Senior Backend Software Engineer

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.

We offer retirement plans, including 401(k), for investing in your future.
