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 energy assets—vehicle chargers, heating systems, and home batteries—optimizing when they consume electricity to align with cheap and green supply. Backed by Energize Capital and Accel, Axle operates at speed in a legacy industry, moving real gigawatt-hours while scaling rapidly.
As a Software Engineer, you will build core infrastructure for connecting 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 own substantial problem-space, talking directly with clients, gathering user feedback, and collaborating with market operators. The company operates a deliberately flat structure with fewer layers, faster decisions, and more ownership for everyone.
Your work will involve forming deep domain and business understanding to execute independently at speed, focusing on outcomes over process, and managing scope and deadlines to deliver high-impact results efficiently. You'll be encouraged to reconsider workflows regularly and explore AI tools aggressively (the company provides unlimited Claude Code tokens).
Tech stack: Python and React for frontend, Docker for deployment, GCP for cloud infrastructure.
The company offers a meaningful equity slice alongside competitive salary (total compensation £75k–£200k base + equity), enhanced parental leave, bi-annual team retreats, and hybrid working with a dog-friendly office near Farringdon (2–3 days per week in-office expected). The company maintains a 1:1 median pay ratio between founders and team to ensure equity.
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; comfort with Python and React; familiarity with Docker and cloud deployment (GCP); ability to work independently with minimal guidance; strong communication skills for client and stakeholder engagement; and alignment with the company's mission to accelerate the energy transition.
