Product Engineer (Backend, Full Stack) | Python, TypeScript, AWS | Climate Techx Energy Tradin[...]

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.

• 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.

• Python
• TypeScript
• AWS
• Event-driven & distributed systems
• CI/CD

• 2-6+ years of software engineering experience
• Comfortable contributing across the full stack
• Experience building data-heavy or highly numerical products
• Product mindset with strong ownership
• Comfortable operating in startup environments
• Excellent problem-solving ability
• Strong communication and collaboration skills

Nice to have:

• Experience within energy, trading or financial markets
• Billing or payments platform experience
• Maths, Physics or Engineering background
• Evidence of exceptional technical achievement or deep personal passion for building products

This role will suit engineers who enjoy solving difficult business problems just as much as writing great code.

• Introductory conversation
• Technical pairing session
• Final conversation with the founders

A collaborative interview process focused on real-world engineering rather than algorithm memorisation.

• Join an exceptionally early-stage business tackling genuine technical complexity
• Work on products involving real-time data, distributed systems and intelligent decision making
• High ownership from day one with direct access to founders
• Small, highly capable engineering team with no unnecessary hierarchy
• Opportunity to influence architecture, product and engineering culture
• Equity alongside a competitive salary
• Work on technology with meaningful climate impact

If you’re a product-minded software engineer who enjoys solving complex backend problems, thrives in startup environments, and wants to build systems where every decision has real-world impact, we’d love to hear from you. #J-18808-Ljbffr

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.
