Backend Developer, CI/CD

Employment: Full Time Experience: Mid-Level

CI/CD Backend Developers are primarily tasked with improving the Continuous Integration (CI) and Continuous Deployment (CD) functionality in GitLab. Engineers should be willing to learn Kubernetes and Container Technology. CI/CD Engineers 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 a few million of CI/CD jobs on monthly.

CI/CD engineering is interlaced with a number of teams across 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,

1. by managing GitLab Runners on top of Kubernetes,

1. by working with other teams that provide facilities to monitor all running applications,

1. 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,

1. Improve performance of implementation, ex.:by allowing us to run 10-100x more in one year,

1. 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.

See the description of the CI/CD team for more details. CI/CD Backend Developers report to the CI/CD Lead.

About GitLab

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.

Avoid the confidence gap; you do not have to match all the listed requirements exactly to apply. Our hiring process is described in more detail in our hiring handbook.

Work remotely from anywhere in the world. Curious to see what that looks like? Check out our remote manifesto.

We value results, transparency, sharing, freedom, efficiency, frugality, collaboration, directness, kindness, diversity, boring solutions, and quirkiness.
