Founding Engineer (EnergyTech / AI)

London Hybrid (3 days onsite) 70k- 120k + Equity

A venture-backed EnergyTech start-up is building a new type of power company designed for the electrified future.

As renewable energy adoption accelerates, the challenge is no longer just generating power, but storing, managing, and intelligently dispatching it. This team is developing software that sits at the centre of that transition, enabling a new generation of energy suppliers built around flexibility, storage, and intelligent automation.

Backed by leading investors and founded by operators with experience from some of the most respected names in the European energy ecosystem, the business has already launched its first product and is growing rapidly month-on-month. The next phase is building the core technology platform that will power a fully integrated energy supplier launching later this year.

This is an opportunity to join a small, highly capable engineering team building core infrastructure for a next-generation energy platform.

The Role

You will work across the full product stack, helping design and build the systems that power both the customer experience and the operational backbone of the platform.

Engineers here take ownership of problems end-to-end, from shaping early ideas through to delivering production features used by customers.

Responsibilities include:

• Building full-stack product features across web, backend services and data systems
• Designing APIs and integrating with hardware and energy data platforms
• Developing AI-enabled capabilities, including LLM-powered workflows and operational tooling
• Contributing to core supplier infrastructure such as billing systems, operational tooling, and internal platforms
• Working closely with founders and customers to shape the product direction

Tech Stack

• Frontend: React, React Native, TypeScript
• Backend: Python, FastAPI, PostgreSQL
• Infrastructure: GCP, Terraform, Airflow
• AI: LLM integrations and AI-driven automation

What They’re Looking For

• Experience as a Full-Stack Engineer building production systems
• Strong engineering fundamentals and the ability to work across backend and frontend systems
• Comfort operating in a fast-moving start-up environment where priorities evolve quickly
• A proactive mindset with a bias towards ownership and solutions
• Interest in the energy transition or climate technology is a strong plus

Engineers who thrive here tend to enjoy working close to the problem, communicating clearly across technical and non-technical teams, and taking initiative rather than waiting for direction.

Package

• 70k- 120k salary depending on experience
• Meaningful equity
• Private health insurance
• Meal allowance and team dinners
• Hybrid working (London office 3 days per week)

Founding Engineer (Python, LLMs, TypeScript) Salary up to £250k + Equity London based onsite
Build the Future of AI Voice
Top VC backed Series A Startup, building AI voice agents that transform how trades businesses operate, from handling customer interactions to streamlining operations at scale.

As a founding engineer, you won’t just ship features; you’ll shape the product, define the architecture, and play a key role in how AI interacts with real-world customers every day. Roles like this are rare: high ownership, direct customer impact, and the chance to build something foundational from the ground up, a hallmark of early-stage AI startup.
What You’ll Do

• Build and ship core product features across a modern stack (Python, TypeScript, cloud, event-driven systems)
• Own problems end-to-end from customer discovery through to production deployment
• Work directly with users to turn messy, real-world workflows into elegant AI-powered solutions
• Balance speed vs scalability, knowing when to prototype and when to harden systems
• Set the standard for engineering excellence across reliability, testing, and security

What You Bring
Experience

• 5-10 years in full-stack engineering (backend-leaning)
• Proven track record building and shipping AI products end-to-end — especially agentic systems
• Experience in early-stage startups (or founder-level ownership mindset)
• Bonus: direct experience working with customers

Technical

• Strong Python or TypeScript skills (async Python is essential)

• Hands-on experience with LLMs and modern AI tooling

• Deep understanding of:

• async/await, coroutines

• httpx, AsyncOpenAI

• production-grade error handling in async systems

Experience with cloud infrastructure (Kubernetes, serverless, distributed systems) Mindset

• You move fast and take ownership
• You’re comfortable with ambiguity and building from first principles
• You care about shipping real products — not just prototypes

If you’re excited by the idea of building foundational AI products from scratch, and want your work to directly shape what gets built, this is that opportunity!
