• Investigate and resolve complex security incidents with limited context

• Partner with engineering and product to balance security with user experience

• Shape Gamma's long-term trust and safety strategy and technical roadmap

What you'll bring

• 5+ years as a software engineer with a focus on abuse, spam, or fraud prevention

• Strong systems thinking and experience building highly available web APIs, with proficiency in at least one programming language and comfort working across a modern web stack

• Hands-on experience implementing trust features like rate limiting, content detection, and fraud prevention

• Experience with event streaming systems (Redis, Kafka, or similar)
