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. 🙂
