Senior Fullstack Engineer, AST: Secret Detection (Ruby)

An overview of this role

As a member of the Secret Detection team, you'll be at the forefront of protecting sensitive data by creating specialized tools that prevent, detect, and remediate leaked secrets in code. Our team focuses on the complete secret management lifecycle - from push protection to pipeline-based scanning, providing automated remediation workflows and audit trails when necessary. We’re passionate about embedding security into the development process seamlessly, allowing developers to focus on innovation while we handle security concerns proactively.

You'll help developers safeguard their credentials, API keys, and other sensitive information by building sophisticated detection patterns, reducing false positives, and creating seamless remediation paths when secrets are discovered. Your work will enable organizations to quickly identify exposed secrets, understand their impact, and efficiently revoke and rotate compromised credentials.

Your impact will be significant and far-reaching, as our solutions protect both GitLab's ecosystem and the sensitive data of thousands of organizations worldwide, preventing costly data breaches before they happen.

Some examples of our projects:

• Prevent secret leaks in source code with GitLab Secret Push Protection
• Verify validity of secret detection findings

What You’ll Do

• Lead the design and implementation of fullstack features for our Secret Detection offering, contributing to both the frontend (Vue.js) and backend (Ruby on Rails, GraphQL).
• Write clean, well-tested code that meets our internal standards for style, maintainability, and best practices for a high-scale web environment.
• Mentor and support fellow engineers, especially those looking to grow into fullstack contributors.
• Collaborate with Product Management and other stakeholders within Engineering (Frontend, UX, etc.) to maintain a high bar for quality in a fast-paced, iterative environment
• Experience with performance and optimization problems and a demonstrated ability to both diagnose and prevent these problems.
• Contribute to code reviews, RFCs, and Proof-of-Concepts that shape the technical direction of the product
• Recognize impediments to our efficiency as a team ("technical debt"), propose and implement solutions
• Work async-first with a globally distributed team, while also participating in necessary sync meetings like high level planning, engineering brainstorming sessions and pairing sessions.

What You’ll Bring

• 3+ years of professional experience with Vue.js, GraphQL, and Ruby on Rails.
• Proven ability to mentor engineers, lead technical initiatives, and drive frontend and fullstack best practices.
• Knowledge of security concepts, vulnerabilities, mitigation techniques, and secure coding practices is preferred.
• Background in developing or using security tools or products
• Hands-on experience with reverse engineering tools such as Ghidra, Binary Ninja, or diffoscope for analyzing, unpacking, and extracting data from compiled binaries and executable files
• Experience with Go programming language or strong motivation to learn
• Ability to work across the stack to deliver end-to-end solutions.
• A strong product mindset and ability to collaborate closely with cross-functional teams including Product, Design and Technical Writing.
• Demonstrated ability to work closely with other parts of the organization.
• Excellent written and verbal communication skills, especially in async-first, remote environments.
• A proactive, self-managing approach to work with a bias for action and ownership.

About the team

GitLab’s Secret Detection team is responsible for the Secret Detection feature category. We want to help developers write better code and worry less about common security mistakes. We do this by helping developers easily identify common security issues as code is being contributed, and mitigate these issues proactively.

We work closely with the larger GitLab security product suite while maintaining our specialized focus on the unique challenges of secret detection. Our technical stack spans Rails and Go backends, Vue.js frontends, and custom parsing engines that enable efficient and accurate secret identification.

We're committed to making sophisticated security tooling accessible to developers of all skill levels. We'd like to continue to expand our capabilities across these workflows, while also continuously improving the result quality across all types of findings our security tools are responsible for detecting. We balance security best practices with practical developer experience to ensure protection doesn't come at the cost of productivity.
