Axle Energy is building software infrastructure for the decarbonized energy system, controlling vehicle charging, heating systems, and home batteries across hundreds of thousands of energy assets. The company operates at high speed in a legacy industry, moving gigawatt-hours of electrons while growing rapidly to meet customer demand. Backed by leading investors including Energize Capital and Accel.
As a Software Engineer, you'll build core infrastructure for connecting to distributed energy devices, orchestrating them, and enabling participation in electricity markets. This is a generalist role spanning product engineering, DevOps, and data engineering. You'll form deep understanding of the energy domain and business to execute independently at speed, focusing on outcomes rather than process. You'll own end-to-end problems, talk directly with clients, gather user feedback, and work closely with market operators.
The company operates a deliberately flat structure with fewer layers, faster decisions, and more ownership for everyone. You'll manage your own time and adapt to changing scope and deadlines, delivering high-impact solutions efficiently.
Tech stack: Python and React for frontend, Docker for deployment consistency, GCP cloud infrastructure, and aggressive use of AI tools (Claude Code) to enhance workflows.
Compensation includes meaningful equity alongside competitive salary (£75k–£200k base + equity), with a deliberate 1:1 median pay ratio between founders and team. Benefits include enhanced parental leave, bi-annual team retreats, and hybrid working with a dog-friendly office near Farringdon (2-3 days/week in-office expected). The role offers direct impact on energy market transformation and acceleration of the low-carbon transition.
