About r2c
Our mission is to make world-class software security available to everyone. This means building program analysis tools that are open source, easy to use, powerful, and fast. It also means building a team with security expertise and a passion for great developer experiences. Most of all, it means working with honesty and respect in a diverse community of dreamers and builders. We’ve redefined static analysis tooling by committing to all of these, and turned our project, Semgrep, into an essential safeguard for code at Snowflake, Dropbox, and more.

Along the way, you will work with a dedicated group of full-stack, backend, and infrastructure engineers, as well as security researchers and program-analysis developers. You’ll learn from and meet with developers and security professionals at organizations ranging from single-person startups to social-media giants. You will attend lunch and learns from all over the company – learning about backend, infrastructure, and full-stack paradigms as well as sales and product ideas. And, as a member of our team, you’ll be a part of the decisions that make an early-stage startup successful. Every feature you build will have an impact on our users’ lives and your own.

  • A passion for software security and developer enablement

Some example projects that you might work on include

  • Adapt semgrep to run in CI workflows
  • Improve the runtime performance of Semgrep
  • Build authenticated rule upload and download to registry CDN
  • Build tag and search functionality over registry to improve discovery of rules in registry

We update these based on market data to make sure they’re above the average for comparable roles.

We also invest in our employees’ well-being and long term success with comprehensive health plans, generous vacation time, 401k matching, learning stipends, and more.
