About Semgrep

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 AppSec 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.

About the role

You will lead the team of Security Researchers responsible for driving the coverage through rules for Secrets, Code, and Supply Chain: across all of our products. This team owns:

• Writing high-quality detection rules

• Advancing research and automation to make rule writing faster and more accurate

• Measuring and improving the overall quality and coverage of detections

As the Manager of the Security Research Coverage team, you’ll report to the Head of Security Research. You’ll set the roadmap, partner with Product Management to focus on the most impactful detection areas, and drive continuous improvements in both accuracy and breadth of our vulnerability coverage. Success in this role means leading a team that delivers world-class detections, scales rule generation through automation and AI, and pushes the boundaries of what modern vulnerability research can achieve.

You will:

• Hire, develop, and grow the team, cultivating a productive, engaging, diverse, and inclusive work environment that aligns with Semgrep's core values

• Work closely with product management, sales, and product development teams across all product lines

• Understand, measure, and elevate the velocity and quality of Semgrep detection rule delivery

• Prioritize your team’s work and schedules, balancing current product needs with strategic research that will help scale the team through AI and automation

• Contribute to the technical direction and to the research (depending on your profile)

• Directly impact the security posture of many customers by improving the quality of our detection

You are ideal for this role if you have:

• 2+ years experience as a People Manager

• 5+ years experience as a Tech Lead in the Security space: App Sec Engineer, Security Researcher, Vulnerability Researcher, etc

• Comfortable working in a fast-paced environments where prototypes are rapidly iterated or discarded

• Comfortable tech leading and mentoring Security Researchers

• Excellent proactive communication skills, both verbal and written

• Fit in our low-ego high-impact culture

• Excitement about building for customers, iterating fast, and seeing solutions solve real developer problems

• Curiosity and a love of new technologies, especially AI/ML

• Comfortable writing code, especially in Python or Rust

Some example projects you might work on include:

• Improve and scale Semgrep’s automated pipelines for generating and validating high-confidence detection rules

• Lead a team to identify and analyze vulnerability patterns (CVEs or from first-principle) across languages and ecosystems, and turn those into detecti
