Staff Software Engineer - AI Developer Tools

About Us

Endor Labs is building the premium Application Security platform for the software development revolution. Modern software is complex and dependency-rich, making it increasingly difficult to pinpoint the risks that truly matter. Endor Labs solves this challenge by building a call graph of your entire software estate—enabling teams to clearly identify, prioritize, and fix critical risks faster.

Trusted by companies that are one or one hundred years old, Endor Labs secures code whether it was written by humans or AI, and whether it's 40-year old C++ code or cutting-edge Bazel Monorepos. Endor Labs was founded by serial entrepreneurs Varun Badhwar and Dimitri Stiliadis, and is backed by leading VC firms such as Dell Technology Capital, Lightspeed, and Sierra Ventures.

How You'll Make an Impact

We are looking for a Staff Engineer to lead our efforts in building developer-centric solutions for AI-driven software development. This is a high-impact role where you will shape how developers write secure code using modern AI coding assistants.

• Build Seamless Integrations: Create robust integrations with AI coding assistants, enabling developers to receive real-time security feedback as they write code.
• Architect MCP & Language Server Solutions: Develop and maintain Model Context Protocol (MCP) servers and Language Server Protocol (LSP) implementations that power intelligent, context-aware security recommendations.
• Drive the "Shift Left" Vision: Embed security directly into the development process, making secure coding the path of least resistance for developers using AI tools.
• Shape the Product Roadmap: Work closely with Product and Engineering leadership to define the strategy for our AI-assisted secure development tooling.
• Lead with Technical Excellence: Set the standard for modular, secure, and maintainable code across our developer tools portfolio.
