About Us

At Axle Energy, we're building the infrastructure that will underpin the decarbonised energy system. Our software moves energy usage to times when electricity is cheap and green, by controlling vehicle charging, heating systems, and home batteries. We control hundreds of thousands of energy assets. We're building in a legacy industry and moving gigawatt-hours of electrons in the real world, but we operate at lightning speed, and we're growing the team to meet customer demand. We're proud to be supported by world-leading investors, including Energize Capital and Accel.

About The Role

Read more about what we're building here.

• Building, optimising, and deploying models that operate reliably at scale
• Developing a deep understanding of energy markets, grid dynamics, and trading strategies
• Taking ownership of the full lifecycle of your work, from research and prototyping through to production
• Writing clean, production-quality code and contributing to robust, scalable systems
• Working beyond notebooks, turning ideas into real-world, productionised solutions

It’d be nice if you could bring:

• Knowledge of the electricity system, specifically power trading
• Comfort speaking to clients (we’re a small team and wear many hats)
• Familiarity with time-series data

Tech stack

We build in Python + React for the frontend (less relevant for this role).

Everything we build lives in Docker, for minimal cross-platform faff and maximal reproducibility.

Unlimited Claude Code tokens - we are aggressive users and explorers of AI, and encourage everybody to reconsider their workflows regularly.

We deploy on GCP.

What's In It For You

A meaningful slice of equity in Axle, alongside a competitive salary, with total compensation ranging from £75k–£200k (base salary + equity).

We operate with a deliberately flat structure and aim to keep pay equitable across the company, with a 1:1 median ratio between founder and team compensation.

Enhanced parental leave to support you through life's meaningful moments.

Bi-annual retreats to strengthen team connection & shared purpose.

Hybrid working - We have a dog-friendly office around Farringdon. To maximize collaboration, we ask that you spend 2-3 days a week in the office.

The opportunity to directly shape the future of energy markets and accelerate the transition to a low-carbon world.

We are extremely keen to build a diverse company, and we're particularly eager to hear from candidates who don't fit the traditional role stereotypes.
