£40,000 - £60,000 / Full-time / On-site / London

The electricity grid is running on 130-year-old technology. While the world has poured attention and money into renewables, EVs, and AI data centres, the infrastructure that everything connects back into has been left behind.

IONATE is fixing that. Founded seven years ago by a neuroscientist and an electrical and control systems engineer, we are building the hardware-software backbone to bring energy systems into the 21st century – making them smart, more reliable, and capable of handling what's coming next.

The tech has been proven. Early commercial projects are going live across Portugal, Spain, the Nordics, Austria, and the UK. The US market is pulling hard. A Series A of $17M closed in 2025.

The technology risk has been removed. Now it's about execution.

Why This Role Exists

IONATE is scaling from around 50 to 100 people across multiple geographies. Matthew, the CEO, is stretched across every part of the business. He needs a right hand – someone who can look across business units and external stakeholders, organise priorities strategically, and protect his time for the work only he can do.

What You'll Do

• Work directly with Matthew day-to-day as his right hand - learn his role in depth and remove the blockers that slow him down
• Own Matthew’s time - keep him focused on the handful of priorities only he can drive, and handle or delegate the rest
• Act as a strategic thought partner - analyse market data and dynamics, understand what drives investors and customers, and bring your own point of view
• Prepare for and sit in on his meetings, including with major global investors and multinational partners, so he goes in fully briefed on what was said and committed to last time
• Drive follow-through from every meeting - write it up, align with Matthew, and get actions in front of the right people
• Act as the filter between Matthew and the wider team - manage what lands on his calendar and decline on his behalf when something doesn’t need him
• Turn long reports and documents into sharp executive summaries, flagging only what needs his attention
• Write documentation and build presentations tailored to the different audiences a CEO needs to reach
• Own the operational detail - coordinating meetings across commercial partners, investors, and internal teams
