Axle Energy is building software infrastructure for the decarbonized energy system. The company controls hundreds of thousands of energy assets and moves gigawatt-hours of electrons by optimizing vehicle charging, heating systems, and home batteries to shift 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 while scaling rapidly to meet customer demand.
As a Solutions Engineer, you will be a generalist engineer bridging software engineering, customer implementation, and solution design. You will work closely with customers to understand their technical requirements, build integrations with distributed energy devices and third-party platforms, troubleshoot complex technical issues, and help shape the product based on real-world feedback.
Key responsibilities include:
- Forming deep understanding of Axle's domain, platform, and customers' technical challenges to execute at speed
- Building and maintaining integrations with customer systems, distributed energy devices, and third-party platforms
- Working closely with customers to troubleshoot issues, support implementations, and design scalable solutions
- Steering customers toward optimal launch plans and user experiences
- Collaborating with the Product team to turn customer feedback into product improvements
- Taking ownership of outcomes and quality of delivered solutions
- Managing your own time and supporting others to adapt to changing scope and deadlines
The role operates within a deliberately flat organizational structure with fewer layers, faster decisions, and more ownership for everyone. You will spend time talking to customers, gathering user feedback, and working with market operators while collaborating with Product to deliver scalable solutions.
Tech stack: Python + React frontend, Docker containerization, GCP deployment, and aggressive use of AI tools (Claude Code).
The company offers hybrid working with a dog-friendly office around Farringdon, asking for 2-3 days per week in-office to maximize collaboration. You will have the opportunity to directly shape the future of energy markets and accelerate the transition to a low-carbon world.
REQUIREMENTS:
The posting does not explicitly state years of experience, specific technical certifications, or formal education requirements. However, the role assumes strong software engineering fundamentals, experience with integrations and APIs, and comfort working across the full stack from backend systems to customer-facing implementation.
