Security Engineer
Greptile · San Francisco
Security Engineer
We want to build agents that autonomously validate code changes. Today that looks like AI that reviews pull requests in GitHub, catching bugs and enforcing standards.
Greptile reviews 5B lines of code every month for 22,000+ customers.
Own Greptile’s security posture across the product, infrastructure, and internal systems. We’re looking for a hands-on Security Engineer to conduct penetration testing, triage bug-bounty reports, remediate vulnerabilities, and harden Greptile’s infrastructure. You’ll work directly with engineers on secure product and infrastructure improvements and critical architecture decisions.
Problems we’re excited about
Coding standards can be idiosyncratic and are often poorly documented; can we build agents that learn them through osmosis like a new hire might?
Can we identify for each customer what types of PR feedback they do and don’t care about in order to increase signal-to-noise ratio?
Some bugs are best caught by running the code. Can we autonomously deploy feature branches and use agents to try to break the application?
How do we secure a product that processes highly sensitive code across cloud, self-hosted, and air-gapped environments?
Trajectory
22,000+ customers

Team
We have assembled a small, talent dense team who have scaled critical functions at companies like Stripe, Google, Figma, etc.
Responsibilities
Own Greptile’s security posture across the product, infrastructure, and internal systems.
Consult on risky code changes and critical architecture decisions.
Conduct penetration tests, fix pentest findings and patch reported vulnerabilities.
Manage our bug bounty program, triage incoming reports, and coordinate vulnerability response.
Harden Greptile’s infrastructure and internal systems. Design, implement, test, and deploy secure product and infrastructure improvements.
Work directly with engineers to make security part of how we build, rather than a final review step.

3+ years of software engineering, DevOps, or security engineering experience
Experience with JavaScript/TypeScript
Deep knowledge of application, infrastructure, and cloud security
Experience working on security-critical products and complex architectures
Strong judgment when evaluating vulnerabilities, technical tradeoffs, and risk
You will like this role if
You want to work on a product that thousands of developers rely on
You want real ownership over the security of a fast-growing technical product
The chaos of high growth and things breaking is exciting to you
You like being in an office every day around other smart people who are excited about what they’re building
You love solving very hard problems.
You specifically prefer working in-person over working remote
