Salary: GBP 75,000 - 200,000 / annual
Axle Energy is building software infrastructure for the decarbonized energy system. The company controls hundreds of thousands of distributed energy assets—vehicle chargers, heating systems, home batteries—and moves them to times when electricity is cheap and green. Backed by Energize Capital and Accel, Axle operates at speed in a legacy industry, moving real gigawatt-hours of electrons while scaling rapidly.
As a Software Engineer, you will build core infrastructure for connecting to distributed energy devices, orchestrating them, and enabling them to participate in electricity markets. This is a generalist role spanning product engineering, DevOps, and data engineering. You'll own as much of the problem-space as you can: talking to clients, gathering user feedback, and working closely with market operators. The company operates in a deliberately flat structure with fewer layers, faster decisions, and more ownership for everyone.
Your work will involve forming deep understanding of the energy domain and business to execute independently at speed, focusing on outcomes over process, and taking ownership for end-to-end product delivery. You'll manage your own time and adapt to changing scope and deadlines, delivering high-impact value efficiently.
The tech stack includes Python and React for the frontend, Docker for all deployments, GCP for cloud infrastructure, and aggressive use of AI tools (Claude Code). You'll work hybrid from the dog-friendly office near Farringdon, with an expectation of 2–3 days per week in-office to maximize collaboration.
Compensation includes a meaningful equity slice alongside competitive salary (total compensation £75k–£200k), enhanced parental leave, bi-annual team retreats, and the opportunity to directly shape the future of energy markets and accelerate the low-carbon transition.
REQUIREMENTS
The posting does not explicitly state years of experience, specific technical certifications, or formal education requirements. However, the role expects: generalist software engineering capability across product, DevOps, and data domains; ability to form deep domain understanding independently; ownership mindset and self-direction; and comfort working in a flat, fast-moving structure. The company explicitly welcomes candidates who don't fit traditional stereotypes and encourages applications from those motivated by the climate mission even if they feel they don't check all boxes.
