Senior Engineering Manager, Guardian

Join our team at Semgrep and play an integral role in shaping the future of software analysis and security.

We run a mixed model — co-located in some geographies and distributed in others.

We think that our culture is more about what we value, who we bring on board, and the quality of our work rather than just being stuck in the same office space. But hey, we do enjoy hanging out with each other and we like to encourage our teams to get together every now and then throughout the year.

Our HQ is located in downtown SF, easily accessible by public transit.

Our satellite office in the Big Apple is small, but mighty.

Enjoy the flexibility and convenience of working from home or wherever you work best.

We look for upside, asking "What can go right?" rather than “What can go wrong?”. We question everything and relentlessly look for the big opportunities to serve our users, impact our mission, and improve ourselves.

We offer health, dental, and vision plans for you and your dependents.

We work hard so it’s important to recharge. Time off is mandated and at least 3+ weeks is encouraged.

Semgrep, the leader in code security for builders, empowers invention without friction. Teams catch, flag, and fix real issues before they ship, powered by security that learns as they build. Semgrep secures code as it’s written and provides guardrails that pave the road for developers to move fast and stay secure. Built for builders and trusted by security, Semgrep lives where developers work, delivering fixes without breaking flow, and giving security teams visibility, control, and confidence.

Semgrep gets smarter as you build, with AI that learns your context to cut false positives and prioritize reachable vulnerabilities, validated by 95% of security reviewers across 6M+ findings. Semgrep makes zero false positives a reality with App Sec teams triaging 80% fewer false positives across Code and Supply Chain, dramatically shrinking the backlog.

Founded in San Francisco and backed by Menlo Ventures, Felicis Ventures, Lightspeed Venture Partners, Redpoint Ventures, and Sequoia Capital, Semgrep is recognized by Gartner in Application Security Testing and is trusted by leading organizations, including Vanta, Lyft, and Dropbox. Learn more  .

As a Senior Engineering Manager for Semgrep Guardian, you'll lead the platform team making security a native property of software at the moment it's written — not a gate applied afterward. Code is increasingly authored inside AI agents, the MCP layer, and the IDE, and Guardian is the platform layer that embeds Semgrep's deterministic security analysis directly into that loop. Semgrep's detection teams own best-in-class SAST, secrets, SCA, and malware engines;
Guardian owns the integration, orchestration, and distribution that turn them into a single, low-latency risk verdict an agent or developer can act on in the moment.
Your team owns the surfaces where that verdict is produced and consumed — agent-harness hooks and the partner SDK, the security MCP server, IDE and editor extensions, the orchestration and policy layer, and the unified risk API. Success is measured not by findings produced, but by adoption of that verdict across Semgrep's products, our partners' agents and IDEs, and the trust developers place in it.

Through Semgrep's culture of transparency, you'll see and influence the decisions that make a startup successful.
