- Build core product systems: Design and implement backend services and end-to-end flows that power the Identity product.
- Go deep on data SQL: Ability to design correct, performant, and maintainable Raw SQL.
- Engineer for reliability and security: Build systems with strong execution guarantees, resilience, and clear operational behavior—especially in a constrained, low-level runtime.
- Own critical architecture decisions: Evaluate tradeoffs, document reasoning, and choose solutions based on requirements—not tool trends.
- Operate with high autonomy: Identify what needs to be built, propose approaches, and execute with minimal hand-holding.
- Use AI responsibly: Leverage AI tools where helpful, while demonstrating the depth to review, validate, and correct AI-generated code.
- Raise the bar through collaboration: Participate in code reviews and technical discussions with a focus on clarity, quality, and long-term maintainability.

- Proven ability to work independently, take ownership, and drive projects from concept to delivery
- Strong engineering judgment: requirements-first problem solving and clear articulation of tradeoffs
- Comfortable working in an environment with limited “black boxes” and high responsibility for core flows
- Ability to work onsite in Miami Tuesday through Thursday as part of our hybrid schedule
- Full-stack experience (with a backend/data emphasis); React experience is a plus
- Experience designing or supporting systems with high correctness requirements (e.g., idempotency, guaranteed execution, fintech/payments-like constraints)
