The core technology stack includes TypeScript, React, Next.js, tRPC, Prisma, and PostgreSQL.
What You'll Do- Build and deliver full-stack features spanning React interfaces, backend services, APIs, and relational data models.

- Improve checkout and payment reliability, accounting for concurrent activity, interrupted connections, retries, and transaction recovery.
- Develop reusable components, internal tools, and workflows that help other engineers build more effectively.
- Monitor and improve the systems you deliver, investigating performance issues across the browser, application, and database.
- Use logs, metrics, and tracing to diagnose production incidents and address their underlying causes.
