About the Role
This is a core infrastructure role at a pre-seed energy tech startup building the foundational systems that power dynamic electricity plans — including a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger. You'll be a key contributor shaping scalable, reliable backend architecture at an early and critical stage of the company's growth.
What You'll Do
-
Design systems that tame complexity and make hard problems tractable at scale.
-
Build and scale core backend services that underpin dynamic electricity plans and billing infrastructure.
-
Move fast with a bias for action, shipping meaningful work in an ambiguous, fast-moving environment.
-
Set and uphold a high technical bar across the codebase and team.
What We're Looking For
-
3–10+ years of backend engineering experience with strong proficiency in TypeScript (Node.js) and asynchronous programming.
-
Solid experience with PostgreSQL and an ORM (experience with Drizzle is a plus).
-
Familiarity with Next.js, including API routes or server components for backend services.
-
Understanding of distributed systems concepts and how to design scalable, maintainable services.
-
Hands-on experience integrating Stripe payments and billing flows.
-
Strong CS fundamentals — formal degree or equivalent practical experience.
-
Excellent written and verbal communication, a strong sense of ownership, and comfort operating in ambiguity.
