Job Description
Staff Backend Engineer
StackAI
• Architect and scale core systems — Design, build, and own the backend services that power our no-code AI platform, from API layer through data pipeline. • Lead authentication and identity infrastructure — Own our SSO, SAML, and OIDC integrations, ensuring enterprise-grade auth that scales with our customer base. • Set technical direction — Define system design patterns, service boundaries, data modeling approaches, and long-term infrastructure strategy. • Mentor and elevate the team — Raise the bar through design reviews, pairing, knowledge-sharing, and establishing best practices across backend engineering. • Drive reliability and observability — Proactively identify bottlenecks, improve performance, and evolve our infrastructure before problems become incidents.
Job Requirements
- 6+ years of backend engineering experience, with a track record of operating at Staff level or as a technical lead on complex, production systems.
- Deep expertise in SSO, SAML, and OIDC — you've built or owned identity and authentication systems, not just consumed them.
- Broad understanding of identity provider (IdP) architecture and enterprise auth patterns.
- Strong proficiency in Python with experience in FastAPI or similar modern frameworks.
- Deep knowledge of distributed systems design, database architecture, and scaling strategies.
- Hands-on experience with SQL and NoSQL databases (e.g., Postgres, Supabase, SQLAlchemy).
- Strong command of cloud infrastructure (AWS: EC2, S3, RDS, Lambda) and containerization (Docker, Kubernetes).
- Comfort operating in a fast-paced startup where priorities shift and impact is immediate.
- Experience with entitlements management, usage-based metering, or billing systems (e.g., Stripe Billing, Lago, or custom metering pipelines).
