Senior Developer, CI/CD
CI/CD Backend Developers are primarily tasked with improving the Continuous Integration (CI) and Continuous Deployment (CD) functionality in GitLab. GitLab CI/CD is widely used by a number of organizations over the world. CI/CD engineers are expected to be self-directed, communicative, and versatile; they should have experience with different developer technologies and frameworks. Engineers working in that position should be willing to learn Kubernetes and Container Technology.
Engineers at that position should always have three goals in mind:
1. Provide value to the user and communicate such with product managers,
2. Introduce features that work at scale and in untrusting environments,
3. Always focus on defining and shipping the Minimal Viable Change.
We, as a team, cover end-to-end integration of CI/CD in GitLab, with components being written in Rails and Go. We work on a scale of processing almost two millions of CI/CD jobs on GitLab.com monthly. CI/CD is interlaced with a number of teams across a GitLab. We build new features by following our direction. Currently, we focus on providing a deep integration of Kubernetes with GitLab:
1. by automating application testing and deployment through Auto DevOps,
2. by managing GitLab Runners on top of Kubernetes,
3. by working with other teams that provide facilities to monitor all running applications, in the future implement A-B testing, feature flags, etc.
Additionally, we also focus on improving the efficiency, performance, and scalability of all aspects of CI/CD:
1. Improve performance of developer workflows, e.g. faster CI testing, by improving parallelization,
2. Improve performance of implementation, ex.: by allowing us to run 10-100x more in one year,
3. Identify and add features needed by us, ex.: to allow us to test more reliable and ship faster.
Being part of the CI/CD team, you have a unique opportunity to use bleeding edge technologies, such as Kubernetes and Docker, and work on Ruby and Go projects. Not only will you work on features that deliver value for hundreds of thousands of organizations around the world, but you will also face massive scale issues with running a CI/CD system.
For this position, a significant amount of experience with Ruby is a strict requirement.
We would love to hire all great backend developers, regardless of the language they have most experience with, but at this point we are looking for developers who can get up and running within the GitLab code base very quickly and without requiring much training, which limits us to developers with a large amount of existing experience with Ruby, and preferably Rails too.
For a time, we also considered applicants with little or no Ruby and Rails experience for this position, because we realize that programming skills are to a large extent transferable between programming languages, but we are not currently doing that anymore for the reasons described in the merge request that removed the section from this listing that described that policy.
If you would still prefer to join the backend development team as a Ruby developer, please consider contributing to the open-source GitLab Community Edition. We frequently hire people from the community who have shown through contributions that they have the skills that we are looking for, even if they didn’t have much previous experience with those technologies, and we would gladly review those contributions.
GitLab Inc. is a company based on the GitLab open-source project. GitLab is a community project to which over 1,000 people worldwide have contributed. We are an active participant in this community, trying to serve its needs and lead by example. We have one vision: everyone can contribute to all digital content, and our mission is to change all creative work from read-only to read-write so that everyone can contribute.
We value results, transparency, sharing, freedom, efficiency, frugality, collaboration, directness, kindness, diversity, boring solutions, and quirkiness. If these values match your personality, work ethic, and personal goals, we encourage you to visit our primer to learn more. Open source is our culture, our way of life, our story, and what makes us truly unique.
