About Kaluza

Kaluza is the Energy Intelligence Platform, turning energy complexity into seamless coordination. We help energy companies overcome today’s challenges while accelerating the shift to a clean, electrified future.

Our platform orchestrates millions of real-time decisions across homes, devices, markets and grids. By combining predictive algorithms with human-centred design, Kaluza makes clean energy dependable, affordable and adaptive to everyday life.

With teams across Europe, Asia and Australia, and a joint venture with Mitsubishi Corporation in Japan, we power leading companies including OVO, AGL and ENGIE, as well as innovators like Volvo and Volkswagen.

What you’ll do

• Own UX strategy for our EU programme end to end, with real judgement over what to prioritise and how, as the market and the team's shape itself still takes form
• Partner directly with Product, Engineering, and Data on the ground locally, including wider teams and client-side engineers,bringing user needs into decisions from the start, not added on afterward
• Use our established research methods to bring real insight into your own design work, and feed what you learn locally back into the wider team's shared understanding
• Lead and grow two designers based in London, building one genuinely connected team across EU and the UK from early on
• Shape how local work becomes part of our shared platform and design system, so what you build here compounds for every client after, not just this one
• Build directly in code where useful, using AI-assisted tools to prototype or ship small front-end changes yourself, closing the gap between design and delivery
• Go beyond representing UX, be an active voice in the trade-offs between PMs and Design, holding the right balance between client-specific needs and our global approach, including directly with clients and stakeholders in workshops, showcases, and pre-sales conversations across the EU market
• Help define what design leadership looks like across a genuinely distributed function, UK, EU, and Australia, while it's still being built

What you’ll bring

Ideally you’ll have/be

• A track record owning UX strategy and delivery end to end for a complex, multi-stakeholder product, ideally in a regulated or operationally complex industry
• Experience designing in B2B or B2B2C environments, for professional, repeat users rather than casual consumers
• Direct experience managing or mentoring other designers, comfortable leading a small team while still doing hands-on design work yourself
• Experience working from, and contributing back to, a shared platform or design system, not just consuming one
• Comfort working close to code, confident using AI-assisted development tools (such as Claude Code) to go from design to a working interface yourself
• A genuine appetite for building something from an early stage, comfortable with ambiguity that comes with shaping a team and a market presence, not just operating inside one already settled

Where you'll work
We offer flexible working, with an expectation of 3 days a week in the office. This gives us the best of both: real time together to collaborate and build relationships, with the flexibility to work in the way that suits you best the rest of the week.

Our Values

• Play to win: Collective pride in decarbonising energy at scale.
• Solve the real problem: Cutting through complexity to focus on real-world outcomes.
• Build trust every day: Consistency, transparency and doing what we say.
• Own the outcome: Full accountability, wins and setbacks, without ego.
• Go further together: Collaboration, respect and different perspectives.

Our Perks

• Financial & Insurance: Discretionary bonus, Alan Mutuelle Health Insurance, x3 Life & Death insurance (Prévoyance) via Alan, and standard Sécurité Sociale contributions (pension, family allowance, unemployment insurance)
• Allowances: 50% commuting expense reimbursement, €200 Home Working Allowance, and €150 Learning Fund
• Time Off & Flexibility: 25 days holiday + bank holidays + RTT days, Moments That Matter Leave, Compassionate Leave, two paid Volunteering Days, Flexible Working, and Career Break eligibility
