Job description

Lead Systems Engineer / Technical CTO | Energy Tech | Fully Remote

Immediate Start

I'm working on an exciting opportunity for a hands-on Lead Systems Engineer / Technical CTO to take ownership of a growing energy technology platform, with the opportunity to shape its technical direction and build out the engineering function as the business scales.

This is a great opportunity for someone who combines strong software engineering skills with a solid understanding of the UK energy retail market, someone who can own the architecture, write code, integrate complex systems and help build the technology behind a new approach to energy supply.

The Role

You'll take ownership of the platform from day one, working closely with the founders and playing a key role in shaping the technical roadmap, product and future engineering team.

Key responsibilities include:

• Owning the platform architecture, technical strategy and roadmap.
• Designing and building customer-facing platforms and dashboards.
• Integrating billing, CRM, customer accounts, metering data and settlement systems.
• Establishing and managing the technical operations required to support an energy supplier.
• Contributing to product design and technical decision-making.
• Building and leading the engineering function as the business grows.

What We're Looking For

• A strong background in UK energy supply or energy retail, ideally within a startup or mid-market supplier.
• Experience designing and integrating distributed systems across an energy supplier's technology stack.
• hands-on experience with industry-standard billing, CRM and customer platforms.
• A track record of building customer platforms and dashboards.
• Experience connecting billing systems, customer accounts and complex data flows.
• The ability to take ownership of architecture while remaining hands-on with development.

Particularly Interesting

Experience with high-frequency transaction ledgers, billing, payments or settlement platforms would be a real advantage, as would familiarity with half-hourly settlement data, matched supply models or building a technical function from the ground up.

The Details

• Location: Fully remote.
• Opportunity: Lead Systems Engineer initially, with scope to grow into a Technical CTO role.

If you're an experienced energy technology specialist who wants genuine technical ownership and the opportunity to build something from an early stage, I'd love to hear from you.
