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. 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. You will: - 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 - 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 COMPENSATION The estimated starting annual salary range for this position is $230,000 to $288,000 USD. The actual base salary will be determined based on a number of factors, which may include job-related skills, relevant experience, qualifications, location, internal equity, and market data. In addition to base salary, total compensation may include equity, variable compensation, and benefits. We view equity as a meaningful part of our compensation philosophy and a way for employees to share in the long-term value they help create. Compensation ranges are reviewed regularly and may be adjusted as the role, individual performance, or market conditions evolve. WHAT WE OFFER (FTE ONLY) Our goal is to competitively and fairly compensate every Semgrep employee with a system that equally rewards those who are vocal and those who are less comfortable making demands during the final steps of the hiring process. To that end, we generate internal compensation bands that are used when discussing and negotiating salaries. We update these based on market data to make sure they’re above the average for comparable roles. We invest in our employees’ well-being and long-term success through a competitive, market-aligned benefits program that meets or exceeds local market standards across all of the regions in which we hire.

WHO WE ARE We bring together people from a wide range of backgrounds and disciplines—from physics and philosophy to formal methods research and full-fledged corporations.
