Hands-on offensive security testing of Go/Python services, with a growing focus on AI/ML attack surface and crypto custody flows

Robinhood's Offensive Security team is hiring a Senior Penetration Tester based in Bellevue (3 days/week onsite) to run application security assessments, code reviews in Go and Python, and threat modeling, while scaling the team's throughput with AI-assisted tooling. The role explicitly covers attacking AI/ML systems (prompt injection, agent misuse, RAG/MCP exposure) and cryptocurrency custody/signing flows, on top of classic web app and cloud pentesting. Expect technical depth checks on real vulnerability classes plus how you use AI as a force multiplier in your own testing.
