  • Experience leveraging AI-first coding workflows and spec-driven development practices using tools like Codex or similar
  • Proven experience working in a monorepo environment (Nx, Turborepo, Lerna, or similar)
  • Strong programming fundamentals, data structures, algorithms, design patterns, and problem-solving
  • Familiarity with relational databases (PostgreSQL preferred) and RESTful/GraphQL API design
  • Experience with cloud platforms (GCP, AWS, or Azure), including CI/CD, containerization, and infrastructure basics
  • Comfortable working with Git, pull request workflows, and modern development tooling


Nice-to-Have
  • Prior experience with .NET (C#) or Java in an enterprise setting
