## Description

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.
