Responsibilities

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.
Work closely with your product and design partners to create a roadmap for the success of your platform that balances iterative changes with big bets
Prioritize and direct your team's schedule, balancing the needs of developing new technology, serving internal and external consumers, and maintaining internal technical quality
Retain and strengthen engineers with coaching and mentorship, regular feedback, performance reviews, and performance management when necessary
Build an environment of trust that rewards creativity, risk taking, and personal responsibility
Continually grow your team through the hiring of diverse, productive, high-level technical talent
Please note, this role sits onsite 3 days a week in either of our office hubs( San Francisco, New York City, Denver, or Boston).
You are ideal for this role if you have:
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
