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, and home batteries—and moves energy usage to times when electricity is cheap and green. Backed by Energize Capital and Accel, Axle operates at high speed in a legacy industry, moving real gigawatt-hours of electrons while scaling rapidly to meet customer demand.
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, spending time with clients, gathering user feedback, and collaborating closely with market operators. The company operates in a deliberately flat structure with fewer layers, faster decisions, and more ownership for everyone.
Day-to-day work involves forming deep understanding of the energy domain and business to execute independently at speed, focusing on outcomes rather than process, and taking ownership for end-to-end products shipped to the world. You'll manage your own time and adapt to changing scope and deadlines, delivering maximum value efficiently.
The tech stack centers on Python and React for the frontend, Docker for deployment reproducibility, GCP for cloud infrastructure, and aggressive use of AI tools (Claude Code) to rethink engineering workflows.
The company offers a meaningful equity stake alongside competitive salary (total compensation £75k–£200k), operates with a 1:1 median pay ratio between founders and team, provides enhanced parental leave, holds bi-annual retreats, and maintains a dog-friendly hybrid office near Farringdon requiring 2–3 days per week on-site to maximize collaboration. The role offers direct impact on shaping the future of energy markets and accelerating the transition to a low-carbon world.
REQUIREMENTS
The posting does not explicitly state years of experience, specific certifications, or formal education requirements. However, the role is described as a generalist Software Engineering position requiring the ability to form deep domain understanding independently, execute at speed, and own end-to-end outcomes. The tech stack (Python, React, Docker, GCP) and emphasis on AI tool adoption suggest comfort with modern development practices. 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.
