An overview of this role
As a Staff Engineer on GitLab's Software Composition Analysis team, you'll drive hands-on implementation of security features that help customers understand and manage risks in their software supply chain. Your focus will be on enhancing GitLab's SCA capabilities in dependency scanning and container scanning. You'll work directly on technical implementation and help the team push forward on three core goals: Gather (introducing data points that help customers understand the urgency of issues, like reachability analysis and supply chain poisoning detection), Integrate (providing other teams with innovative collection techniques for better workflows), and Optimize (solving data correlation at massive scale). You'll contribute hands-on code, help solve novel technical challenges, and establish patterns that improve how the distributed team works together across multiple time zones.
What you’ll do
  • Implement complex features in dependency scanning and container scanning, shipping improvements that increase scan coverage, improve accuracy, and drive adoption of GitLab's SCA capabilities
  • Solve novel technical problems in SCA, establishing reusable patterns that reduce delivery time and improve engineering effectiveness across the team
  • Guide architectural and implementation decisions in collaboration with engineering managers, product managers, and peer staff engineers to improve scalability, reliability, and delivery outcomes across the team's SCA architecture
  • Contribute code, design reviews, and technical mentorship that raise quality standards, improve maintainability, and strengthen performance across the codebase
  • Collaborate across GitLab's security domain to align SCA work with related efforts in vulnerability management and adjacent product areas, accelerating delivery of shared roadmap goals and improving coordination across related security efforts
  • Identify and resolve technical debt, prioritizing changes that improve team velocity, code health, and long-term maintainability across the team's core SCA services
  • Translate product needs and customer feedback into technical solutions in partnership with product and security stakeholders, delivering features that address high-impact customer risks and advance shared roadmap goals
What you’ll bring
  • Hands-on experience in Software Composition Analysis and the ability to contribute to complex security features in dependency scanning and container scanning
  • Deep hands-on expertise in building and evolving dependency scanning and container scanning capabilities
  • Demonstrated ability to design solutions that balance complexity, performance, and maintainability
  • Expertise with backend technologies, particularly Go and/or Ruby on Rails, with ability to pick up new technologies quickly
  • Ability to evaluate technical tradeoffs in SCA and security tooling, with proven success delivering maintainable solutions that help customers manage software supply chain risk
  • Ability to work effectively in distributed, async-first teams across multiple time zones
  • Experience explaining complex technical and security concepts to engineers and stakeholders
About the team
The Software Composition Analysis team is part of GitLab's Sec Engineering group, and we focus on building capabilities that help customers identify and manage risks in their software supply chain. We work across areas including dependency scanning and container scanning, and we work closely with product, security, and adjacent engineering teams to close important feature gaps in GitLab's platform. Our team members are distributed across regions including Europe and North America, so we rely on clear documentation, asynchronous communication, and thoughtful coordination across time zones. This opportunity is centered on helping us deliver complex security features while balancing hands-on technical progress with strong team execution.
