An extensible developer-friendly application security platform that scans source code to surface true and actionable security issues with AI-assisted SAST, SCA, and Secrets Detection solutions. Backed by Lightspeed, Sequoia and Felicis.
About the role
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.
What they're looking for
- 3+ years of experience leading software engineering teams
- A strong foundation in product development and bringing products to production via a multi-disciplinary engineering team — including understanding best practices for design, iterative milestone creation, and utilizing customer feedback
- Familiarity with agile development principles and iterative milestone development
- A strong desire to help engineers and other leaders grow through coaching and mentorship
- You have opinions on building durable platforms, APIs, or SDKs for demanding consumers, have worked on developer tooling, IDE/editor extensions, or AI agent, MCP, and protocol integrations, or have built a security product before
