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

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.
