Develop and maintain automated tests (unit and integration) and CI/CD pipelines to ensure quality and rapid delivery.
Enforce security best practices, authentication/authorization, and data privacy across backend services.
Implement end-to-end changes across backend services with clean, maintainable, well-styled code.
Translate product and data requirements into robust technical specifications and solutions.

Knowledge of security best practices, authentication/authorization, and data privacy in backend services.
Ability to match an existing codebase's style and implement changes end-to-end.
Excellent collaboration skills across product, data, and frontend teams.
A demonstrated track record of exceptional performance or notable achievements.
Nice to Have:
Experience with AI productivity tooling (e.g., Cursor or similar).
Background at companies working in AI/ML infrastructure, LLM tooling, or marketing analytics SaaS.
