Our mission is to enable everyone to contribute to and co-create the software that powers our world. When everyone can contribute, consumers become contributors, significantly accelerating the rate of human progress. This mission is integral to our culture, influencing how we hire, build products, and lead our industry. We make this possible at GitLab by running our operations on our product and staying aligned with our values. Learn more about Life at GitLab.

An overview of this role

As a Backend Engineer joining our team, you will work on the foundational layer of GitLab Continuous Integration (CI). Our team is largely involved in scaling CI, along with ensuring our CI features remain performant and reliable by driving improvement to critical database infrastructure.  As many of our efforts are Engineering led, you will also have an opportunity to provide input towards our CI data management strategy. 

About the team

TheCI Platform group was created in 2024, as part of the Verify stage, upon evaluating that we needed a dedicated team to work on the operational aspects of GitLab CI to ensure our platform remains best-in-class. The team has been largely focused on partitioning CI/CD Data and has started to explore aspects of CI Data retention and improved data management. You will get to dive into some complex technical challenges and collaborate with our infrastructure teams to strategize on solving these exciting challenges related to how we scale and grow CI.  More details can be found in our technical roadmap for Verify.

We live our transparency value by designing our systems and planning our work with publicly facing artifacts.  Some examples of our work include: 

What you’ll do  

  • Implement performance and scale improvements for GitLab CI in a fast-paced, iterative environment.
  • Collaborate with other stakeholders within Engineering (e.g. other Database or Infrastructure teams) to set best practices in managing a sustainable platform and to maintain a high bar for quality.
  • Advocate for improvements to reliability, security, and performance.
  • Craft code that meets our internal standards for style, maintainability, and best practices for a high-scale web environment. Maintain and advocate for these standards through code review.
  • Recognize impediments to our efficiency as a team (“technical debt”), propose and implement solutions.
  • Ship small features and improvements with minimal guidance and support from other team members. Collaborate with the team on larger projects.
  • Work with your team to assess technical feasibility and discuss how best to iterate on complex problems. This might involve working on proof-of-concept proposals to help guide technical discussions.
  • Take ownership of what we build, focusing on stability and availability.

What you’ll bring

  • Professional experience with Ruby on Rails and PostgreSQL.
  • Experience working with a platform or complex application (Large scale is a bonus).
  • Familiarity building and deploying software with CI/CD or other internal tooling. 
  • Familiarity with distributed, scalable and reliable systems.
  • A user of modern DevOps platforms. (GitLab is a bonus.)
  • Proficiency in the English language, both written and verbal, sufficient for success in a remote and largely asynchronous work environment.
  • Experience working in a highly agile, iterative software development process.
  • Self-motivated and self-managing, with excellent organizational skills.
  • Demonstrated ability to work closely with other parts of the organization.
  • Share our values, and work in accordance with those values.

Linux Foundation is hiring a Remote Backend Engineer (Contractor)

Job Description

You will join the LFX platform team for a high-impact role in building a mission-critical application for the entire open source ecosystem. You will be part of an open-source-obsessed team where you do more than writing code: you will lead your own projects, be in contact with users, make architectural decisions, manage infrastructure, and you will always be encouraged to take the initiative. Furthermore, at the Linux Foundation, you will be contributing to a fully open-sourced codebase. Your contributions will be public, and you will join us in building toward an open future.  

The expected salary range is $90k-$120k based on your experience level. The position is fully remote within European time zones (CET +/- 2 hours).

Our tech stack 

We use a modern, lightweight tech stack to provide an enjoyable and productive development experience. 

  • The backend is built with Node.js, backed by a PostgresSQL and a QuestDB database. 

  • We use Kubernetes for orchestration hosted on Oracle Cloud. 

  • We use Temporal for orchestrating long-running and distributed workflows.

  • We use Vue.js for frontend development, with Tailwind CSS for styling. 

We have a philosophy of buying-over-building. We try never to reinvent the wheel and use the best open-source solution for problems that are not our core. We work with exciting, cutting-edge technologies such as LLMs, text and vector search engines, and semantic database layers. You will find the team is always excited to try new technologies. 

Your tasks 

  • Build the backend of an application that will potentially help millions of developers and companies in the open source ecosystem

  • Develop a lean and scalable architecture capable of handling billions of data points. 

  • Lead your own projects

  • Support in managing our infrastructure

  • Work closely with the whole development team on the technical big picture, and contribute to strategic and company-wide decisions with the entire team.

Qualifications

  • 5+ years of professional experience working with backend technologies. 

  • Proficiency in Node.js, SQL, and Kubernetes. Experience with time series databases is an advantage.

  • Knowledge of scaling applications for big data 

  • Professional experience with Snowflake or other data warehouses. Knowledge of DBT is an advantage. 

  • A strong team player, willing to put on many hats and contribute towards the team's goals. 

  • Professional proficiency in written and spoken English. 

  • Able to working during the European time zone (CET +/- two hours)

  • Having previously built or maintained an open-source project is a plus.
