Who We Are

Threefold is an energy technology company with a growing UK business and an international footprint.

We build intelligent battery storage and energy management technology that helps businesses reduce electricity costs and carbon emissions while making better use of available energy.

Our systems are behind‑the‑meter, plug‑and‑play and independent of solar. They require no planning permission, no construction programme and no operational downtime. We charge when energy is cheap and clean, and discharge when it is expensive and carbon‑heavy, displacing fossil generation at peak.

We’re led by Founder & CEO Luke Gamble, alongside an interdisciplinary leadership team drawn from energy, engineering, technology, finance and real estate.

Between them, they’ve structured gigawatts of renewable transactions, scaled commercial teams across continents and built businesses from zero.

As our UK team grows, we want to bring the same care and rigour to our organisational structure and people experience that we bring to our technology.

What We Stand For

• Evidence over claims: We don’t do generic offsets or greenwashing. Everything we deliver is measured, audited and certified.
• Zero disruption: Our technology fits around the customer, never the other way round.
• Pace with purpose: The energy transition has a deadline. We work like it does.
• Partnership, not supply: We’re in the business of sharing the value we create.

Your New Adventure

This is the first dedicated People hire at Threefold, with a UK-centric remit and a close working relationship with Luke and the senior team.

Your immediate priority will be to help the business navigate its next phase of growth: shaping an evolving organisational structure, supporting several planned Q4 hires and making sure new colleagues join with clear responsibilities, expectations and support.

Partner with the Founder & CEO

You’ll work closely with Luke to understand the business goals and translate them into practical people priorities. You’ll be a trusted sounding board, bringing sound judgement, constructive challenge and hands‑on support as plans develop and decisions need to be made.

Shape the Organisation as It Grows

You’ll help the senior team clarify roles, reporting lines, responsibilities and capability gaps. As new colleagues join, you’ll ensure the structure supports the work that needs to be done and gives people clarity about how they contribute.

Support Q4 Hiring

You’ll help define the roles we need, shape how we interview and assess candidates, and support the senior team in making considered hiring decisions. You’ll keep the process moving while ensuring each appointment supports the wider business plan.

Make Joining Count

You’ll develop onboarding that helps new colleagues understand the business, build relationships and become effective quickly. From the practical essentials to clear objectives, you’ll make joining Threefold feel purposeful from day one.

Build Practical People Foundations

You’ll put proportionate UK people processes in place, covering contracts, right-to-work checks, policies and employee relations. You’ll help managers navigate their responsibilities and know when specialist advice is needed.

Support Performance and Culture

You’ll establish clear expectations, useful feedback and honest conversations, helping the business retain its pace and entrepreneurial spirit as the team grows.

About You

You’re an experienced People professional working independently, whether you call that fractional, consultant, interim or portfolio.

You’ve supported a founder-led scale-up before and understand the importance of building a productive, trusted relationship with the CEO. You can listen, advise, challenge constructively and turn agreed priorities into action.

You’ve helped businesses adapt their organisational structure as they grow, bringing clarity to roles and responsibilities without creating unnecessary layers.

You’re comfortable supporting recruitment and onboarding alongside the wider People remit. You can move between a conversation about organisational priorities and the practical work needed to welcome a new starter.

You have strong working knowledge of UK employment law and practice, with the judgement to manage day-to-day matters and recognise when further expertise is required.

You’re commercially aware. You understand the business goals and can explain how your recommendations will help achieve them.

You’re comfortable with ambiguity and changing priorities. Working closely with a founder can bring demanding conversations and quick changes of direction. You bring composure, perspective and a practical way forward.

You’re direct, warm and resilient, with the confidence to contribute your own view and the flexibility to work collaboratively. There’s no established HR team behind you, so you’ll enjoy taking ownership and delivering hands‑on.

Desirable

• CIPD qualified.
• Experience in energy, cleantech, engineering or deep-tech scale-ups.
• Experience supporting a period of concentrated hiring and organisational change.
• Exposure to investor-backed or high-growth funding environments.
• A track record of building people foundations that can evolve with the business.

Why Join Threefold?

• Work directly with the Founder & CEO and senior team, with a clear connection between your contribution and the business goals.
• Help shape the UK organisation at a significant stage of growth.
• Make an immediate impact through Q4 hiring, onboarding and team development.
• Build practical people foundations with scope to influence how they work.
• Apply your experience in a fast‑paced, innovative clean energy sector and asset class.
• Take on a varied, sometimes challenging brief where progress is visible and rewarding.
• Flexible, outside IR35 engagement that fits alongside your other clients.
• Remote‑first working, with time in West London to build relationships and support the team.
• Negotiable Day Rate (Outside IR35)
• Strong scope to extend beyond the initial engagement.
