## About the role

We're hiring a Senior Application Security Engineer to own the security of the software we build. You'll partner closely with engineering to embed security into the Software Development Lifecycle (SDLC), keep our dependencies and supply chain safe, and make sure the product our customers trust is built on a secure foundation. You’ll also have the chance to influence our product, as an internal SME and early security user, your feedback loop directly shapes what we ship.

## What they're looking for

- 5+ years of extensive security engineering experience within product / application security, upholding the highest Trust standards
- Strong hands-on engineer who ships - you produce and automate, you don't just manage process
- Strong software engineering skills, comfortable working in code across the stack (e.g. Python, Go, Typescript, and/or similar)
- Depth in application/product security: secure SDLC, threat modeling, code scanning, and supply-chain / dependency security
- Fluency with the modern AI landscape and how it’s influencing the security picture - staying up to date with the rapidly changing environment
- Able to flex up and down: strategic when it matters, in the weeds when it counts
