Volter is a top-tier climate VC-backed B2B energy tech platform building the products that make clean, renewable power simple for businesses everywhere. The energy transition is a huge and vital opportunity, but it's currently too difficult for commercial & industrial companies to achieve. Historically, the energy industry has been too opaque, complex and lacking in trust. We’re fixing that. We aim to be the “Octopus Energy for industry”: a modern tech platform providing new renewable energy products with radical transparency — accelerating deployment of renewables and helping customers cut costs and carbon without complexity. We’re excited to use technology to help our customers deploy & utilise more renewable energy and fast-forward the energy transition - and we need your help!

As a key member of the team, you'll own end-to-end delivery of product features across the stack, building both customer-facing interfaces and the backend services, APIs and data-powered functionality behind them. You’ll work closely with founders, engineers, data scientists and commercial teams to solve complex problems and ship customer- and internal-facing features at high velocity — days, not weeks — while laying pragmatic, scalable foundations for our supply operations across pricing, billing and data ingestion.

- Strong proficiency across the stack: backend (ideally Go and/or Python) and frontend (ideally TypeScript and React)
- Comfortable working with data-intensive features, architectures and systems, with an appetite to keep improving how we scale them
- Proficient with data: schema design, query optimisation and data modelling, including time-series data
- Experience designing and consuming REST APIs; event-driven patterns and background workers
