Software Engineer

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
Software Engineers at Axle build the core infrastructure for connecting to distributed energy devices, orchestrating them, and allowing them to participate in electricity markets.
This is a generalist Software Engineering role, encompassing product-engineering, devops, and data engineering. We encourage engineers to own as much of the problem-space as they can: you’ll spend time talking to clients, getting feedback from users, and working closely with market operators.
At Axle, we work in a deliberately flat structure. That means fewer layers, faster decisions, and more ownership for everyone.

Software engineering at Axle looks like

• Forming a deep understanding of the domain & the business, so you have enough context to execute independently at speed

• Focusing on outcomes, not process, and taking ownership for the end product you ship into the world

• Managing your own time and those of others to adapt to changing scope and deadlines, delivering 80% of the value in 20% of the time

Tech stack
🐍 We build in Python + React for the frontend
🐋 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. If you’re motivated by our mission, please do reach out, even if you feel you might not ‘check all the boxes’.
