Full Stack Product Engineer at Octopus Ventures-backed climate tech startup

Deadline: 6 Jul 2026

London, England, United Kingdom

Overview

Seed-stage climate tech startup backed by Octopus Ventures and Aenu VC building the AI-native operating system for commercial solar. Salary is not disclosed.

Job Description

You will lead the development of an AI-native asset management platform for the UK’s £22B commercial solar market. Moving beyond ticket‑taking, you’ll own problems end-to-end—from real‑time energy monitoring to automated billing. Join a high-performing team scaling ARR 6x and build the digital backbone for a smarter, cleaner energy grid.

Why this role is remarkable

• Massive Ownership: Building “Workspace,” the company’s future‑defining AI-native interface, from the ground up rather than just maintaining legacy systems.
• Proven Traction: The platform is already live with 20 customers and over 5,350 solar projects across the UK, backed by a recent Seed round from elite climate‑tech investors.
• Direct Impact: Your code directly optimizes renewable capacity, helping maximize every kWh of energy in a mission‑critical infrastructure sector.

Responsibilities

• Build End-to-End: Ship features across the full stack using Node.js, TypeScript, and AWS to solve complex challenges in data ingestion and event‑driven architectures.
• Ship AI‑Native Features: Develop the first AI‑powered asset management command center for renewable operators, integrating LLMs with live project data and workflows.
• Engage with Customers: Interface directly with solar asset operators to understand their pain points and translate real‑world needs into high‑impact product solutions.

Ideal Candidate

• Product-Minded Engineer: ~5+ years of experience and a track record of owning complex systems end-to-end, ideally in a scrappy, fast‑paced startup environment.
• Technical Generalist: Proficient in TypeScript and Node.js with the ability to move fluidly between frontend and backend depending on the problem at hand.
• Entrepreneurial Driver: Thrives in ambiguity, communicates proactively, and is comfortable making deliberate trade-offs to balance technical excellence with commercial speed.
