Job Description

Please note: this position is full time and in Berlin (you need to already be in Berlin too). We don’t use agencies.

Most messaging networks are created to serve their creators. Email is designed to serve humankind. For over 50 years inspired technicians have architected email to provide the greatest good to the greatest number. Their openness and design principles made email the world’s #1 communication channel and identity provider with 4.2 billion users (2x Facebook). Email is a critical foundation stone of the Web.

Lightmeter is reinventing email infrastructure to overcome threats from centralised tech oligharchs like Microsoft and Google. An epic platform war is behind fought behind the scenes to wrestle control over digital comms and incorporate it into closed service platforms, where the customer is a product to be sold to the highest bidder.

We are 3 years of research and 1 year of development in to building Lightmeter Control Center - the all-in-one mailops management system repeatedly featured in Heise and ZDnet. It’s fully Open Source (on GitLab) – feel free to check the unit and user acceptance test code coverage : ) . Our engineering team has a background in embedded and fintech, with a focus on performance and feedback.

A mix of public and private funding fuels our work, and we’ve been recognised by the European Commission as part of ‘Next Generation Internet’. We have hundreds of active users, a few of whom we interview each week, including banks, public universities, Internet Service Providers, and marketing agencies.

Our mission is to strengthen the foundations of digital society by making mailtech easy and convenient.

That’s a brief intro to what you’ll be working on. But first, you need to know if you’ll even like working with us. Let’s talk about life at Lightmeter and then we’ll go into detail about what we’re looking for.

Who you’ll be working with

One luxuary of being an early-stage team is that you get to work directly with everyone. That said, you’ll be reporting to Sam, our CEO. He gets easily excited about engineering patterns and workflows, and likes bright colours and house music with vocals.

You’d work along-side Lead Developer Leandro, who calls himself a Software Craftsman, and who others call a philosopher. Leandro has deeply held unfashionable beliefs like “all code should be fast and light”, and cares more about design patterns than what language he’s coding in. He love the outdoors and pines for the mountains.

Suela is our Product Manager and x-ray seer of quality and value. She has a nack of turning our telescopes around, pointing out better perspectives, opportunities, and efficiencies. She’s an Open Source fangirl, community organiser of the OpenLabs Hackerspace, and secretly learning Python so she can make bots to replace herself. Just kidding!

How You’ll Work at Lightmeter

We work hard to make working here a great experience, and have a team of truly exceptional people — the kind you’ll be excited to work with. You’ll get to design and create new components and services, working on features like those on our roadmap (https://lightmeter.io/roadmap).

Here’s how we operate

No Crazy Hours
You’ll very rarely work more than 40 hours per week, unless you really want to. Ocassionally things can heat up, but noones going to force you to work more than is comfortable. When you do work overtime you balance it out with time off afterwards. We work hard and smart, planning carefully, but we’re in this for the long haul: sustainability trumps anything short term.

Face time and alone time
Most of us have worked fully remote before and miss the benefits of face time, so we like to work together a lot of the time. However focused time alone, in cafes or home-office is nice too, so we aim for a good mix. So long as you can reach the people you need, when you need them, and vice versa, your preferences for office vs remote work shouldn’t be an issue.

Take Vacation
A small team means it’s easy to coordinate time off to relax and recharge. Notice you’ll be away a week in advance is usually enough.

Up Your Game
We’re serious about helping you improve your craft. Everyone wins when you get better and your job, and enjoy the process. Think conferences, online courses and subscriptions, dedicated time away from work to learn something new.

Compensation and Legal
We can’t currently offer you a salary to compete with Amazon or Microsoft. What we can offer you is the same salary that we are paying ourselves: €50,000 / year.

We’re an early-stage startup, funded, pre-revenue, and growing. We are owned and managed by our Founders. Making sustainable, profitable products with a committment to openness is hard; we’re demonstrating how it’s done. If you care deeply about digital freedom, empowerment, and collaboration, you’ll probably fit right in!

What we’re looking for

Lightmeter has ambitious goals and our team is growing to meet them. You’re the Software Engineer we’re looking for if you’re collaborative, mission-motivated, creative, disciplined, and productive. (So far, so good?)

You love solving complex problems — both internally and for your users — and know what it means to build a mature, evolving product. You are more focused on the outcome than on the output of your work, and prefer to deliver something useful sooner, rather than something perfect later. You welcome feedback, and are curious about users’ challenges and how to address them. You demand a lot from your colleagues and expect the same in return, taking personal pride in collective achievement.

Requirements (these are real, actual requirements)

• You must live in Berlin most of the time, so we can meet up and work together sometimes
• You must have at least five years working in the software industry, of which at least four are as a software engineer.
• You must have experience working in cross-functional teams. And we really mean that cross-functional part — in other words working directly with designers, quality assurance, product managers, or other related roles.

Our tech stack (repos: https://gitlab.com/lightmeter)

• Golang
• SQLite
• VueJS
• A little Python
• Some big data

Recommended skills

• Golang
• Git with large and distributed teams
• Linux (server and desktop) and tools such as make, SSH and shell scripting
• Docker and related technologies
• TDD and SOLID

Ideal skills

• Development of high performance, distributed systems
• Continuous integration / delivery
• Some Javascript
• Some Python
• Email related technologies, such as SMTP and Postfix
• Standard crypto libraries and principles
• VueJs
• Interest in learning (and teaching!); Rust is welcome

Work Remotely

• No

COVID-19 Precautions

• Remote interview process
• Virtual meetings

• You are interested in the big picture! You want to know and understand how everything is connected, starting with our public APIs, to our internal services and the PostgreSQL database. It is your goal to ensure an error free operation for all our production systems through a mixture of code reviews, unit + integration tests and monitoring.

We know you are in high demand. Here is why we are different and why you will love working for us:

• Our office is located in the middle of Berlin and is easily accessible using public transportation. We will procure your preferred technical devices, so that you can code as productively as possible. We also offer flexible working hours and the possibility to develop yourself further not just in your work-related area of expertise, but in other areas as well.
• We have experts in the IT, as well as in all other departments, with excellent connections to other companies throughout Berlin and Germany. You can learn a lot of new things and experience how to build a “FinTech” from the ground up and how to establish it in the market.
• After creating a solid base of operations in Germany over the last 8 years, we plan to realize several large projects in coming months, which build upon our existing payment infrastructure.

We will be happy to tell you more about this in a personal chat.

Job Description

Today, some Python using TDD. Tomorrow, clean code in Go and Elixir. Next week, maybe pair programming in Node.js? Feeling like writing a custom Nginx module in plain C? We have that too!

Sounds too cool to be true? Well, that’s exactly how we roll here in the Tech Team at caseable!

Don’t let yourself be fooled by a quick visit to the (fancy!) caseable.com website. What seems to be yet-another-boring-ecommerce-startup, is actually much more behind the scenes. We are a tech platform that allows other businesses from different sizes to achieve great customer experience, by horizontally increasing the range of products available with smart cross-selling solutions. You would have never guessed it, right?

Not to mention that we do quite a lot of image processing and provide solutions to our production facility (yes, we have a factory and manufacture physical products too!), with systems that will generate PDFs, control printers, organize logistics and much more.

This is a great opportunity to join a passionate team and make substantial impact on our business growth. You will experience supportive team members and the freedom to use your technical expertise and initiative to achieve shared goals. This position requires authentic curiosity and will to learn every day. We focus on quality and maintainability of what we do, in order to maximize the company goals in the long term, while executing urgent tasks with surgical precision when needed. We expect strong organizational skills, critical thinking and enthusiasm for achieving company and self-oriented goals.

What we offer

We offer you the opportunity to be part of an international team who is not afraid of learning on a everyday basis. You will have the possibility to experiment with new technologies and the freedom to choose your own equipment (high-end Linux or Mac laptops, with UHD external monitors) and software (your favorite IDE or simply Vim if you want).

Our environment is very supportive, where proposals for change and suggestions for improvements are encouraged. In addition, we offer flexible working hours and home office possibilities, an informal working environment with flat hierarchy, and competitive salaries. You will also enjoy our BBQ’s and events together with the caseable team.

As learning is a fundamental part of our style, you can expect to be going to congresses, conferences and meetups, doing workshops and reading books and other technical material in a regular basis.

Skills & Requirements

Your most important skill…

…is that you are open minded and eager to learn new technologies. You receive and give honest feedback and criticism, never taking it to the personal level, but as a fundamental part of achieving excellency.

We run on a microservices architecture, with containerized services in a very polyglot environment. We expect that you find this incredible, very exciting and maybe a bit scary, but in a good way. Python, Node.js, Elixir, Go, C and PHP are currently used, but we already have plans to introduce others, like Rust, Erlang, Lua and literally anything else that we believe will be a great tool for the task given.

Responsibilities

• Code according to industry and team standards, adhering to good practices
• Write maintainable, readable code with extensive test coverage, ideally applying TDD
• Work with source control, dev/stage/prod release cycle and continuous integration
• Get actively involved in the code and functional reviews of fellow developer’s work
• Be able to spot logic and functional issues and effectively communicate feedback
• Actively engage with team members to discuss backlog items, design issues, and best coding practices
• Create technical documentation
• Optimize application for maximum performance, scalability and maintainability
• Working and developing RESTful APIs
• Be in direct contact with infrastructure topics and understand the systems architecture
• Work especially well with green field projects and sometimes with some legacy systems (luckily we already managed to kill most of these).

Skills & Experience

Mandatory:

• Backend development, independent of the programming language, but including at least two of the following:

• Python

• Elixir

• Go

• Node.js

• PHP

• Erlang

• C

• Linux, Bash & command line feels like home to you

• Database knowledge (SQL and NoSQL)

• Good knowledge of HTTP and RESTful APIs

• Adherence to good practices and standards

• Focus on quality, maintainability, readability, scalability and performance

• Likes to work in an international, multicultural team

• Enjoys pair programming, code reviews and knowledge sharing

• Good English skills (written and verbal)

Good to have:

• AWS
• Continuous Integration
• Ansible
• Terraform
• Microservices architecture

Job Description

We are looking for a Golang developer who helps us develop an MVP for a nice Infrastructure as Code project. The MVP consists of a command-line application and a REST API for managing AWS cloud infrastructure in Golang. The project is running only for a few weeks, so you’ll have the opportunity to contribute a cool project right from the start!

tl;dr

• Develop a Golang command-line application and a REST API
• Strong focus on internal and external software quality
• Ambitious project context in the AWS cloud (Infrastructure as Code, High Availability, a high degree of automation)
• For 10 to 16 hours per week
• We speak English and German
• AWS cloud / Infrastructure as Code / Part-time / Freelance

Project Background

We are developing the prototype of an innovative product for managing cloud infrastructure. It is all about running web applications in the AWS cloud in an easy-to-use, reliable, and automated way. Our users should be able to create and maintain the resources that they need without any external help. Behind the curtains, there is a framework that manages those resources in the AWS cloud with Terraform. This concept aligns with the Infrastructure-as-Code principle, which aims at providing documented and managed-like-source-code infrastructure definitions. We set a strong focus on economic factors, in that it should be viable to run both small and large applications and to scale those applications with high load and amount of users. The platform should be highly available and self-repairing – nobody should be on-call and responsible for fixing server deployments in the middle of the night. We have already validated a solution for creating and managing such an infrastructure, and we are in the process of bringing it to life.

The Task at Hand

The platform’s user interface is a command-line application which talks to the REST API, which we also develop. We want to implement these tools in Golang, and engineering has just started. We have a strong focus on software quality: in the end, we want to have a well-designed, robust software architecture with clear responsibilities and interfaces. The product should be automatically testable and maintainable for an extended period. An important factor will be integrating several data sources to deliver the right information to the user at the right time. The challenge lies in the heterogeneity and complexity of the data sources (for example, Terraform and AWS). It is also important to us that the product is intuitively usable: it should transform hosting infrastructure from a bothersome task to something fun. To achieve this, we want to gather user feedback and act on it iteratively.

Your Qualifications

You should have considerable experience with Golang and see yourself on an intermediate-to-senior level. In particular, you should engage with topics such as software architecture, testing on unit/integration/end-to-end level, and picking the right frameworks and libraries. You are also excited about clear software architecture and clean, well-maintainable code. We really care about this! ;) If you’ve got experience with infrastructure tools such as Terraform, Docker, Kubernetes, or cloud platforms such as AWS or Azure – that’s a plus, but we don’t expect you to know everything. And you won’t have to dive deep into all those topics (depending on your personal preferences, of course). There are more bonus points if you know how to integrate 3rd party CLI apps in a stable and reliable way.

The Scenario

You’re living in Berlin, Potsdam, or somewhere nearby, and you have one to two days per week to spare. The project is sponsored by a company for digital products in Münster (Zweitag). However, there is no need to travel there because you work together with a team member who lives in Berlin. The current project is projected to take six months. If it all works out fine, we can see you being invited to work with us for longer. 🙂
