Energy is humanity’s most valuable resource. NOVA is building the software backbone that will power the installation, optimisation, and scaling of the clean-energy transition.

As one of our earliest team members, you'll play a critical role in driving our vision forward, shaping our product, and creating lasting impact. Join us if you're passionate about solving climate change and excited to build something that truly matters.

What the job involves:

• Build and ship core product features across the full stack.
• Help design and implement the core systems that power the OS for energy installers - from workflows and scheduling to data, automation, and integrations.
• Own features end-to-end: problem definition, architecture, implementation, deployment, and iteration.
• Work closely with founders and customers to deeply understand user pain and translate it into elegant, scalable solutions.
• Move fast when speed matters, and slow down when foundations matter.
• Shape our technical direction, engineering culture, and early hiring decisions.

Must haves:

• You’ve shipped production systems - 2–5 years experience designing, building, and operating full-stack applications in production.
• You’re fluent in TypeScript and Python - They’re core to our stack, but you choose tools pragmatically and can adapt to other languages or technologies as needed.
• You think like a product owner - You can put yourself in the shoes of our customers and deliver products that are 10x better.
• You're extremely ambitious - A strong track record of exceptional performance.
• You move fast with AI - You use appropriate tooling, in particular LLM agents in your coding workflow to deliver fast.
• You’re confident using automated testing - To validate the correctness of important aspects of the software you develop.

Nice to haves:

• Experience building CI/CD pipelines and infrastructure as code tooling like Terraform
• You’ve developed applications on one or more of the major cloud platforms like AWS/GCP/Azure.
• You’ve built for the real-world before - Built software used in physical industries such as energy, construction or manufacturing.
• You’re a proven self-starter - Built and shipped your own side projects, tools, or products outside of formal roles.

• 25 Days Holiday (excl. bank holidays)

Our culture:

• Mission obsessed - We're not here to build another startup. We're here to fix the planet.
