About the RoleJoin a pre-seed-funded energy tech startup that is building the operating system for the next generation of energy.

- Build and maintain API routes and server-side services using TypeScript (Node.js) and Next.js.
- Work with PostgreSQL and Drizzle ORM for reliable, performant data access.
- Integrate and extend Stripe-based billing and payment flows.
What We're Looking For- Required: Proficiency in backend development using TypeScript (Node.js) with a strong grasp of asynchronous programming.
- Required: Experience with PostgreSQL and at least one ORM (Drizzle preferred) for data access.
- Required: Experience with Next.js, including API routes or server components used for backend services.
- Required: Familiarity with distributed systems concepts and designing scalable, maintainable core services.
- Required: C1+ professional language proficiency (English).
- Experience integrating Stripe payments and related billing flows.
- Strong written and verbal communication with an ownership mindset.
- Strong CS fundamentals - formal degree or equivalent practical experience (3-10+ years of relevant backend experience).
Tech Stack- TypeScript, Node.js, Next.js
