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

• Ruby

• Passion for tested software: unit testing, automated tests, TDD

• You can’t imagine how to code without Git

• 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
• Docker
• Monitoring tools (NewRelic, Kibana, Graylog, PagerDuty, etc)
• Scrum, Kaban
• Jira, Confluence

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. 🙂
