Intermediate Backend Engineer, SSCS: Supply Chain

An overview of this role

As an Intermediate Backend Engineer on the SSCS Add-On team at GitLab, you'll help build a dedicated software supply chain security feature for regulated enterprise organizations. In this role, you'll contribute to capabilities that help customers control software dependencies, verify artifact integrity, and identify malicious packages before they reach production.

Your work will sit at the intersection of backend engineering, product integration, and security-focused development. You'll build in Ruby on Rails, work alongside Go services as needed, and help connect Add-On functionality with GitLab's existing security scanning experience so findings are surfaced consistently for users. Because the team is small, you'll have meaningful influence on implementation details, team practices, and the product experience.

This role is part of GitLab's all-remote, async-first, values-driven environment, where clear written communication and thoughtful coordination across time zones are essential.

What you’ll do

• Implement well-scoped backend features across the Add-On's supply chain security product, including package policy integrations, ingestion pipeline improvements, signing and verification support, and reliability-focused work, delivering maintainable code on agreed timelines and meeting team-defined delivery commitments.
• Build and maintain integrations between Add-On functionality and GitLab's existing software composition analysis scanning infrastructure so findings appear consistently and accurately in merge request security reports, reducing integration issues and supporting a reliable user experience.
• Write and maintain comprehensive automated test coverage, including RSpec and integration tests, to improve test reliability, reduce regressions, and support safe, consistent releases as the codebase grows.
• Take on work across multiple feature areas as priorities evolve, contributing as a generalist where the team needs support most.
• Participate actively in code review by giving thoughtful, actionable feedback and incorporating feedback constructively into your own work to help maintain code quality and reduce rework.
• Contribute clear internal documentation for the features and behavior you ship so teammates can support, extend, and troubleshoot the product effectively.
• Coordinate with adjacent Software Supply Chain Security teams, including Dependency Firewall and Malware Database, as the Add-On brings together capabilities from across GitLab, helping deliver aligned functionality and smoother cross-team execution.
• Collaborate effectively in an async-first environment across global time zones, including occasional off-hours overlap when needed, to keep work moving and decisions documented clearly.

What you’ll bring

• Backend development experience with the ability to deliver maintainable production code.
• Solid proficiency in Ruby on Rails and strong PostgreSQL fundamentals. 
• Familiarity with Golang, or a willingness to learn and work across both Ruby on Rails and Go.
• Strong testing discipline, including experience with RSpec or an equivalent testing framework.
• Clear, direct written communication skills and experience collaborating with distributed teammates in asynchronous workflows.
• Ability to manage scoped work independently, communicate progress clearly, and adjust as team priorities shift.
• Interest in package ecosystems such as npm, Maven, PyPI, or OCI containers, or adjacent experience that helps you ramp in this domain.
• Interest in software supply chain security, dependency management, DevSecOps, or security-adjacent product development, with the ability to apply security considerations in backend development work.

About the team

The SSCS Add-On team is part of GitLab's Software Supply Chain Security stage and is focused on building a commercial offering that addresses real supply chain security challenges for enterprise customers. The team works on capabilities that combine multiple parts of the GitLab product into a more complete security solution for organizations with strong compliance and risk management needs.

The work is both technically interesting and strategically important. The team is building in a space shaped by fast-moving threats, evolving customer requirements, and close coordination with nearby teams across the broader security area. That combination creates an environment where engineers can contribute to product direction while solving practical backend challenges in a visible part of GitLab's platform.
