About your team and your mission

You would be joining the Endpoint team, which develops an agent running directly on developers' machines to detect secrets and sensitive configurations before they leak — and centralize this information for security teams.
The product is already live with over 100 daily active users and is entering its scale phase. It's the perfect time to join: the foundation is solid, and the upcoming architectural decisions are the ones that will determine how we move to the next order of magnitude.

The technical challenges are up to the role:

• Across-platform agent(macOS / Linux / Windows), deployed directly in developers' environments

• A Rust-based scan engine, built for performance and low footprint

• Real-time data ingestion and structuringat scale

Your role will be cross-functional, high-visibility, and high-impact:

• Drive architectural decisions— You define how the agent and platform evolve to scale. Your vision shapes the team's technical choices and influences engineering as a whole.

• Guide and grow engineers— As the team's technical reference, you mentor, challenge, take part in code reviews, and raise the collective bar over the long term.

• Contribute directly to the code— This role isn't just oversight: you're in the code on the most complex and foundational topics.

• Work closely with Product— You are a key counterpart for PMs to frame product ambitions, navigate technical trade-offs, and co-build the roadmap.
