You’ll partner across the company to solve high-impact security problems and ship secure, reliable, AI-powered features quickly and safely.
About the Team:
The Product & AI Security Engineering team sits at the intersection of product, platform, and AI at Gusto. We prioritize high‑leverage projects that reduce risk, harden our foundations, and unlock faster delivery for other teams.

- Provide leadership in promoting security and software engineering excellence.
Here’s what we're looking for:
- 7+ years of experience as a backend engineer, building and operating large-scale server-side services and APIs
- Deep experience with authentication and authorization, such as SAML/SSO, RBAC, and ABAC.
- Proven track record building secure, highly available distributed systems and services.
- Hands-on experience with modern security tooling and practices (e.g., SAST, DAST, SIEM, SCA).
- Proficiency in one or more of: Ruby, Python, Kotlin, JavaScript/TypeScript
- Experience with AI tools for coding (ex: Cloud Code, Cursor, Github Copilot)
- Bonus: experience with authorization platforms/policy engines (e.g., Open Policy Agent, SpiceDB) and technologies like GraphQL, gRPC, Kubernetes, Terraform, Traefik, Flask, Okta.
- Strong collaboration skills and comfort breaking down complex, cross‑cutting security and AI problems into clear, practical solutions.
