Founding Product Engineer

About the RoleThis is a founding engineering hire at an early-stage, AI-powered platform built for industrial energy procurement and cost optimisation. You'll join a small, high-conviction team and take genuine ownership — from shaping the architecture to shipping features directly with customers. The platform handles real-time energy market data, forecasting, portfolio management, and optimisation at enterprise scale. If you're a generalist engineer with a strong product mindset, comfort with ambiguity, and a curiosity for data-intensive domains, this role is a rare opportunity to have outsized impact from day one. Note: Visa sponsorship is not available for this role. What You'll Do• Own the full product lifecycle — from design and requirements through to deployment and iteration. • Translate product objectives into clear, actionable requirements in close collaboration with customers. • Design simple, iterative solutions to complex energy procurement and market problems. • Build performant backend services for a highly data-intensive application. • Develop intuitive, elegant user interfaces for a sophisticated decision-support system. • Train time-series forecasting models for power consumption and renewables production. • Develop and refine linear optimisation algorithms to reduce customer energy costs. • Help define and evolve the core tech stack — including PostgreSQL, TypeScript, React, and Python. What We're Looking ForMust-haves: • 2+ years of software engineering experience delivering scalable web applications in an early-stage startup environment. • Proven track record of delivering full product features independently, working directly with customers. • Strong software engineering fundamentals — you write robust, maintainable, scalable code. • Hands-on experience building backend services for data-intensive applications. • Experience building frontend UIs for complex, data-rich decision-support tools. • A genuine product mindset: you think
