Senior IDE Engineer, Semgrep Analysis Foundations

About Semgrep

Semgrep is on a mission to make it expensive to exploit software. As the team behind the most popular SAST, we built the Semgrep AppSec Platform to deliver industry-leading code, dependency, and secrets scanning to enable organizations to ship secure code quickly without slowing down development.

With fast, customizable code analysis across large codebases, Semgrep helps teams catch vulnerabilities early and fix them faster. Leading companies like Snowflake, Plaid, Figma, Lyft, and Dropbox rely on Semgrep to secure their software.

Semgrep is funded by top investors, including Felicis Ventures, Lightspeed Venture Partners, Menlo Ventures, Redpoint Ventures, and Sequoia Capital.

About the role

As a member of the Semgrep Analysis Foundations team, you’ll enable developers to code securely — whether they handwrite code in an IDE, work in conjunction with LLM-enabled tools, or let agents run autonomously. You’ll own our IDE integrations and MCP server, adding whatever functionality is needed to help developers find and fix vulnerabilities in their code with minimal friction. This includes the code analysis underlying our scanning, so that you can make improvements as needed to our actual detection software. All the while, you’ll ensure we release improvements frequently and painlessly, supporting our culture of fast experimentation. Through Semgrep’s culture of transparency, you’ll see and influence the decisions that make a startup successful. Your decisions will be key to making Semgrep a world-leading static-analysis project, giving you lasting influence not only at Semgrep, but in the world’s developer community.

You will :

• Own and improve the reliability and user experience of our IDE extensions across VSCode, IntelliJ, and other popular editors
• Design IDE-native workflows that integrate seamlessly with AI coding assistants and autonomous development agents
• Maintain the infrastructure for our MCP (model context protocol) server
• Ensure frequent, easy releases to all supported platforms
• Build comprehensive observability and debugging tools that help us quickly identify and resolve issues in diverse customer environments
• Advocate for architectural decisions that make our code easy to reason about and allow us to scale with an exponentially growing number of users
• Advise and mentor other engineers via thoughtful code reviews, planning discussions, technical documentation, and formal mentorship

Our benefits are for everyone, so that you’re taken care of, and we work with individuals to make sure they have what they need, whether that’s quiet work space, adjusted hours, or something else.

Who we are

We have people from France and the Philippines, physics and philosophy, formal methods research and full fledged corporations. We’re new parents and new grads, aspiring authors and aspiring Americans, dog lovers and dogfooders. We get together often to bike, bake, and meet up in parks. In our interactions, we believe respect and honesty go hand in hand, and prioritize both.
