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. 🙂

Job Description

We created Jodel to let you instantly connect, share, and engage with the community around you. We built thriving local communities across Europe and continue to expand globally. With over 1 million users creating more than 6 million posts per day, we have one of the industry's highest retention rates. We've attracted great investors such as Christophe Maire, Adam d’Angelo, and the Floodgate Fund, and even been the subject of several academic papers.

We're growing our Engineering team around a culture of sustainability and empowerment. We're dealing with dynamics such as being local, signup-lean and many more, which give us new problems to solve -- we’re literally breaking new ground in the Social Network space. Data-driven by default, with a bias for quality and code sustainability, and fostering a solid DevOps and Automated Testing culture, Jodel's Engineering team is the place to be!

Attitude we're looking for * You’re naturally motivated and proud of doing great work; * Numbers and data are the best way to drive your decisions; * You have a strong personality, sense of ownership and responsibility; * You put people and human interactions above processes and rules; * You understand the value of "measure twice - cut once" and you work by this mantra; * You own your successes and your failures, and constantly seek to improve; * You keep your mind on the product we're building, and are permanently aware of how each small action influences its success.

What we value * Your studies were in Computer Science, Mathematics or Engineering; * You're a problem solver, and you’re eager to experiment and learn new things; * You write code optimizing for clarity and readability; * You value testing very highly; * You write software aiming at reducing the cost of change; * You enjoy pair programming and code reviews, and see your job as a collaborative effort rather than solitary work; * Engineering work is mostly about compromises and so you're always open to discuss different approaches to problems; * You're happy to collaborate with your community and industry, either in open source projects or presenting at meetups and conferences;

Skills we're looking for * You have experience with either Node.js or Golang, but you're definitely interested in doing more Golang as part of your job; * You want to work in Distributed Systems; * You have experience with MongoDB and Redis, beyond "I have played with it in the past"; * You have a bias to automate things when possible; * You’re ready to embrace a DevOps culture, because an Engineer’s work doesn’t end after we ‘git push’; * You're ready to work with Linux, Cloud providers, Docker, Kubernetes

What do we offer? * An Empowered Team -- Engineering owns tech debt and tech improvement decisions; we collaborate tightly with our product team but we're all very mindful not to step on each other's toes. We own technical decisions, take responsibility and are accountable for them.. * Preventive culture, rather than reactive -- While some of us participate in on call duties, we have a very low amount of actual production emergencies. A lot of energy goes into fixing root causes and we are very proud of not having anyone in firefighting mode. * Career building is part of the deal -- you don't join to just write tests and contribute to the product - you also join to improve your career. We pay special attention to your personal development and make sure you're focusing on the skills that matter the most to you. * Lean processes -- we try hard to cut meetings and processes to a minimum, to ensure that you’re being productive. And we encourage all interactions to be direct and open, not forcing you to go through any intermediaries to get your work done. * United in diversity -- with people from all over the world, from Tunisia to France, from India to the Poland, we are multicultural by default and proud to be so. We all come from different walks of life and cultural backgrounds, and we continue to push for diversity in our team! * We're building a team, not just making money -- we solve hard problems together but we also relax and have fun. From team cooking to going on company trips, from office parties to go-karting, we'll make sure you have a good work-life balance. * The future will be amazing -- the list of non-trivial challenges we'll be dealing with includes developer APIs, security issues, scaling access to a lot of data (among other things we can't tell you about :-) ); all of this with location and anonymity as their own dimensions in Jodel. * No one else is doing what we're doing -- it's that simple. We're pioneering local communication and since communication is a basic human need, our work is super exciting. On top of that, we are one of the few large scale European Social Networks. There’s not that many and we're very proud to be "Made in Europe".

Job Description

*The product: A containerized data science environment*

Our ambition is to create a platform that gives data scientists a flexible, consistent, and simple environment based on Docker containers, where their code can be written in a large variety of languages (Python, R, Go, Scala). This tool then turns their code into stateless functions that can be easily deployed into powerful data pipelines.

*The stack*

Kubernetes, OpenFaas, Docker

*The challenge*

• Having great DevOps engineering support is crucial in order to guarantee that our micro-service based platform runs smoothly and reliably, no matter where it is deployed (we support cloud and on-premise deployments).
• Our components are mostly written in Go, with some Scala and a bit of Python mixed in, and all of them expose well-defined interfaces. We always keep operational requirements in mind when developing new services.
• We're looking for someone who can actively drive our roadmap in the area as part of our technical operations team, who can evaluate new technologies and wants to be a great partner for the rest of the tech team.

*Your profile*

• You have senior-level experience with complex production deployments, know your way around Kubernetes and have in depth operational experience with at least one of the big three cloud providers (AWS, gcloud, Azure).
• Software engineering experience is a big plus, particularly in Go.

*About us*

*Who we are*

• Contiamo is a Berlin-based, fast-growing tech company. We offer a flexible data platform enabling businesses to create interactive, data-driven decision tools and automations. Our mission is to combine sophisticated data science with a great user interface and experience.
• We are a tech-driven company and keep a close watch on recent scientific developments and emerging technologies. We love open-source. We are a very international team with interesting people from all over the world (95% of us have relocated to Berlin).

*How we work*

• We strongly believe in the importance of uninterrupted time to get stuff done and quality over quantity when it comes to working hours. We prefer to keep our schedule meeting-light and work in a library-like atmosphere during the core hours.
• We believe the ability to give and get constructive feedback and express divergent ideas is crucial to making innovation come to life. We live a very open discussion culture and prefer the evaluation of ideas based on merit over top-down decision making.
• We strongly believe in ownership of one's features, from spec to implementation to operation. We also understand that ownership comes with a sense of responsibility towards others that depends on the results of our work.
• We believe that everybody should be able to find meaning in their work. We match assignments based on both ability and individual interests and discuss your progress and individual needs every 3 months.
• We don't see people as "resources" and genuinely care about each other. We also understand that there's more to people's satisfaction and engagement than fancy perks and cool events. We continuously work towards an environment providing a lot of autonomy, transparency and development opportunities and rely on everybody's feedback to hold us accountable for maintaining our high standards.

Sound like the kind of atmosphere you would work well in? We're looking forward to receiving your application! We see the interview process as a mutual opportunity to get to know each other — at eye level. That's why we always strive to respond within hours, not weeks.
