About the Role

This is a Backend Engineer role on the core infrastructure team at a pre-seed energy technology startup building the operating layer for next-generation dynamic electricity plans. You will help design and scale a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger, foundational systems that power how energy is priced, delivered, and billed.

What You'll Do

  • Design for complexity: architect scalable, maintainable backend systems that handle real-world energy billing and market data challenges.

  • Scale the core: build and improve the infrastructure underpinning dynamic electricity plans and reliable billing flows.

  • Ship with ownership: take features from design through production with a bias for action and a high bar for quality.

  • Raise standards: contribute to engineering culture, code quality, and technical decision-making as an early team member.

What We're Looking For

  • At least 3 years of experience building reliable backend infrastructure in production environments.

  • Proficiency in TypeScript and Node.js, including strong command of asynchronous programming patterns.
