Senior Software Engineer - (Home Energy)

About Enode The grid was built for predictable, centralised power. Today it's absorbing intermittent supply from grid scale solar and wind, alongside dynamic demand from EVs, heat pumps, and home batteries. The missing piece is software that can connect and orchestrate these devices at scale. Enode provides the infrastructure layer that makes this possible. Our Connect API gives energy companies a single integration to 1000+ devices across 80+ brands. Our optimisation tooling gives energy companies the building blocks to manage those devices locally - think smart charging for EVs. Our Flex product turns those connected devices into a flexible, controllable asset for energy companies. We work with device manufacturers across the energy hardware ecosystem - from EV brands to heat pump and solar inverter producers. Our customers are energy retailers, utilities, and traders building the next generation of energy services. We're backed by Y Combinator, Lowercarbon Capital, and Creandum. The decisions made now will shape how the energy system gets built. We're looking for people who take ownership, move fast, and care deeply about the role technology can play in the energy transition. What we're looking for: We're hiring a Senior Software Engineer to help build the software layer that makes home energy devices work as one system. The Home Energy team owns Enode's integrations and APIs for batteries, solar inverters, HVAC, and smart meters, along with the home energy management (HEM) system and statistics that customers build on. You'll build integrations with leading OEMs and help mature our API surface into the unified control layer for the home, at a moment when customer demand for battery and home energy optimization is accelerating. You'll join the Home Energy team, reporting to the team's Engineering Manager. You'll collaborate closely with your PM, fellow backend engineers, and our partnership and commercial teams, from assessing OEM API feasibility to shaping how customers control energy assets through our platform. In this role, you will: • Build and maintain integrations with OEM cloud platforms across batteries, solar, smart meters, and HVAC. • Design and evolve our home energy APIs, unifying telemetry and controls across HEM system, batteries, and curtailment into a product surface customers can build optimizations on. • Improve observability and vendor performance across our integrations, and take part in the team's triage rotation. • Work with partnership and commercial teams on API feasibility for new OEM integrations. • Build strong relationships with the customers who rely on our platform, working alongside your PM and commercial partners, and let what you learn from them shape what we build. • Debug and ship production features in Node/TypeScript on our AWS-based stack. • Take a product-engineer mindset, balancing speed, quality, and customer impact in your day-to-day decisions. Curious what you'd actually be building? Explore our API docs and the Enode Tech Blog to see what we ship and how we think about it. This role will be right for you, if: You're an ambitious backend engineer who likes to own things end to end: from an ambiguous problem, through design and integration work, to something shipped and running in production. You find integration challenges satisfying rather than frustrating, including working with third-party APIs of varying maturity, and you're energized by tough technical problems. You're comfortable navigating ambiguity and bringing clarity and structure that help a team move forward. You collaborate naturally with engineers, PMs, and commercial partners, and you like being close enough to the product to influence where it goes. Above all, you care about building software with real-world impact that supports the shift toward a cleaner, more flexible energy system. You bring: • Experience building and maintaining backend services in production, ideally in API or integration-heavy systems. • Strong skills in designing for reliability, scalability, and performance. • Ability to own work from initial scoping to production rollout, including iterating based on customer or usage insights. • Comfort in fast-moving, sometimes ambiguous environments where teams create clarity together. • Clear, thoughtful communication across engineering, product, and customer-facing teams. • A product mindset: you care about solving the right problem and making life easier for customers and teammates. Nice to have: • Experience with TypeScript/Node, AWS services, PostgreSQL, TimescaleDB, or similar production tooling. • Familiarity with home energy assets (batteries, solar/inverters, HVAC, smart meters), energy markets, or IoT/device ecosystems. • Prior exposure to API-first products or integration platforms. • On-call or incident response experience. What we offer: • Opportunity to join and impact an early-stage climate tech startup with global aspirations as we sc
