Software Engineer (Mid-Senior)

Software Engineer | Energy & Climate Tech | London (Hybrid)

A fast-growing energy technology company is building the intelligence layer for a cleaner, more resilient power grid - and they're looking for engineers who want their code to have measurable, real-world impact.

The team is developing large-scale optimisation systems that coordinate EV charging, home batteries, and heating to automatically shift demand toward cleaner, lower-cost energy. The result: a smarter grid, lower emissions, and better outcomes for millions of households.

Backed by top-tier investors and scaling rapidly, this company is laying the technical foundation for a low-carbon energy network.

Why this role

• Build systems used by millions, not demos or dashboards

• Work with real-time data, optimisation, and ML-driven decision-making

• High ownership, high trust, and meaningful influence on product direction

What they're looking for

• Engineers who enjoy solving complex, real-world problems

• A genuine interest in energy, climate, or sustainability

• Comfortable working in a fast-moving startup environment

Python is the primary language, but engineers from any modern OOP background are welcome.
