Caseable Logo
Backend Engineer with Caseable
Berlin, Germany€50k - €70k
7 months ago

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).

  • Python

  • Elixir

  • Go

  • Node.js

  • PHP

Golang Developer for PaaS MVP - Part-Time with Zweitag GmbH
Berlin, Germany€50k - €70k
10 months ago

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. 🙂

Senior Golang Backend Developer for Blockchain/FinTech with Herdius
Remote / Berlin, Germany€30k - €100k
1 year ago

Job Description

About Herdius:

Herdius is a Berlin based Blockchain Company. We are working on building homomorphic distributed private key generation which then is turned into value bearing products in different sectors. Currently we are very close to open beta-testing for the Herdius-Crypto-Wallet.
What we focus on on the blockchain field specifically is interoperability and trading. When connecting different chains on the key level, users can eliminate communication channels, bridges and complex systems. In other words, users can do cross-exchange and chain token swaps very conveniently and profitably for the user due to the cross-exchange arbitrage opportunities. The broader vision is one day to replace API auth keys with public-private key cryptography in order to provide layered access to user data.

All this makes for a crypto eco system and hedge fund that pays interest on all cryptocurrencies (that right now are unfortunately somewhat unusable and just laying around on wallets).

About the role:


Herdius is seeking for a Gopher Guru - an experienced Senior Golang Backend-Developer - to join our team of smart and visionary individuals. Experience in Blockchain is not necessary but a big plus.

We do not look at this role as another standard job but rather as great opportunity to build something really meaningful und amazing. Become a member of our great collective of top nodge engineers and people - altogether working to create cutting edge tech for the masses.

Besides the Herdius HQ in Berlin our Dev-Team is working mostly remote on different time-zones - so this vacancy surely also is location agnostic.

We would expect you to contribute at least 20hrs per week for part-time but joining full time is possible, too.



Cool things you will work on:

  • Implementation and design of Herdius’ consensus algorithm and p2p order routing protocol.
  • Lots of work around trading and high volume data handling and transfer.
  • Design and implementation of a low-latency, high-availability, and performant algorithmic hedge fund and exchange order book.
  • Integration of the Herdius distributed private key generation protocol.
  • Constant performance testing and improvement of our architecture.
  • Working on new financial products that have not been seen in the crypto world, setting up the base-layer infrastructure of a trading system and hedge fund

Skills & requirements

  • Strong proficiency & experience working with Golang
  • 3+ years of experience as a backend engineer, language agnostic but Go, React, NodeJS, Vue.JS, Scala, Angular, Rust preferred
  • Experience and passion working with distributed systems and networking
  • Strong interest in blockchains and related technologies
  • Passion for delivering quality, secure code with loads of testing
  • User authentication and authorization between multiple systems, servers, and environments
  • Interest in privacy and cryptography, trading and financial service
  • Understanding fundamental design principles behind various consensus algorithms
  • Understanding differences between dPOS, DAGs, Plasma, BFT, aBFT, etc.
  • Implementing automated testing platforms and unit tests
  • Proficient understanding of code versioning tools, such as Git

Interview Process

Your education or professional experience at the end of the day does not matter to us. It all comes down to us being convinced by your skills and drive! 
We mainly look for people who are passionate about projects they work on and have the drive to see a project through. Our code is mostly done in Golang with some Solidity for connectivity with Ethereum.

How to apply:

Send anything that reflects on your knowledge and experience in the field. Besides a CV/LinkedIn-profile you can send links of your GitHub/Stack Overflow/Portfolio/ or something awesome you’ve built that you’re simply proud of.

Software Engineer with Cash Payment Solutions GmbH
Berlin, Germany€35k - €45k
1 year ago

Job Description

How do you design and implement an API that communicates with thousands of cash registers in all stores of REWE, Penny and real,-? How do you automatically transfer money between different banks?

Software Engineer (m/f/*)

At Barzahlen we operate Germany’s largest independent payment infrastructure. Customers can use different services in several supermarkets to e.g. pay their invoices and deposit or withdraw cash from their private bank accounts using smartphone apps.

In order to further develop our systems and to implement new projects we are looking for software engineers. It is important for us that the following applies to you:

  • You love coding! Software development is not just a job for you. You are coding on private projects as well and you are interested in the latest developments in the industry. You are fluent in at least one programming language.
  • In the future you want to program in Ruby and Go! It would be awesome, if you’ve already worked with these two languages in the past but in case you haven’t, that’s also no big deal: In our experience developers get productive in these languages very fast.
  • You are interested in the big picture! You want to know and understand how everything is connected, starting with our public APIs, over to our internal services and the PostgreSQL database. It’s your aspiration to ensure an error free operation of all our production systems through a mixture of code reviews, unit + integration tests and monitoring.

High requirements merit appropriate compensation. We are competing with other companies for your time and knowledge. So why should you decide to join us? Naturally this is quite hard to answer and depends on a lot of factors. Therefore we would be happy to answer all your questions regarding Barzahlen in a personal chat.

You can expect the following working for us:

  • Our office is located in the middle of Berlin and easily accessible using public transport. 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 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-Startup” from the ground up and to establish it in the market.
  • After creating a solid base of operations in Germany over the last 4 years we plan to realize several large projects in the coming months which build upon our existing payment infrastructure.

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