Senior Software Engineer - Encryption & PHI

We are looking for a senior Python engineer who has built security-critical product systems.

You will join the Core Engineering team and build the systems that determine how StackAI encrypts customer data, manages keys and signatures, handles PHI and PII, protects customer credentials, and enforces tenant and authentication boundaries.

We’re looking for an engineer who brings strong security judgment to the software they build: someone who can move between architecture and implementation, reason carefully about trust boundaries, and turn security requirements into reliable product capabilities.

This is hands-on backend engineering in an existing, fast-moving codebase. You will write production Python and take projects from initial investigation and design through implementation, migration, rollout, and operation.

The systems you build will shape which sensitive and regulated workloads enterprises can run on StackAI and how confidently they can put them into production.
