The Company
The energy industry is undergoing one of its biggest transformations in decades.
We're partnering with a well-funded, early-stage climate technology company building software that sits at the heart of the transition towards a cleaner, more intelligent electricity grid.
Rather than improving existing systems, they're building an entirely new platform from the ground up - combining real-time data, distributed hardware, AI, and energy trading to solve complex problems that have a genuine impact on the future of energy.
Still a small engineering team, they're at the stage where every engineer has a meaningful influence on the product, technical direction, and success of the business.
The Role - Product Engineer (Backend, Full Stack) | Python, TypeScript, AWS | Climate Tech x Energy Trading | Real-Time Systems, High Ownership, 0→1 Product Builds | London (Hybrid, 3 Days) | £80-120k + Bonus + Equity
You'll join a highly technical, product-focused engineering team building software that powers real-time operational and commercial decision making.
This is a backend-first role (Python ≈70%) with exposure across the full stack, working on data-intensive systems where correctness, scalability and performance genuinely matter.
You'll work across multiple product areas - from backend services and APIs through to customer-facing products, internal tooling and complex operational workflows.
Expect plenty of ownership, ambiguity, and the opportunity to solve difficult engineering problems from first principles.
What You'll Be Doing - Product Engineer (Backend, Full Stack) | Python, TypeScript, AWS | Climate Tech x Energy Trading | Real-Time Systems, High Ownership, 0→1 Product Builds | London (Hybrid, 3 Days) | £80-120k + Bonus + Equity
Building and owning backend services in Python
Developing scalable APIs and data-heavy systems
Designing products that process large volumes of real-time information
Working closely with Product to deliver features end-to-end
Contributing across the stack where required (TypeScript)
Building software that interacts with physical devices and operational systems
Improving reliability, performance and engineering standards as the platform scales
This is a fast-moving Product Engineering environment where engineers are trusted to own problems rather than simply deliver tickets.
