• You thrive in fast-paced startup environments
• You are an expert in Python, with strong experience working with Django and large monolithic codebases
• You have significant experience with Rust
• You have experience working on embedded software / on-device applications (software installed and running on a machine, not web applications)

What the job involves

• 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
• 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
• 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
