About the Position

Head of Product (Flex)

Location: London, United Kingdom

Department: Product

Salary: £112,000 - £140,000

Work Location Type: Hybrid Office (3+ days per week)

Join Kaluza as Head of Product (Flex) to lead our residential VPP platform globally, shaping the future of clean energy.

Responsibilities

As Head of Product for Flex, you will:

• Set and own the global product strategy for Flex, translating Kaluza's company-level strategy into a roadmap spanning device integrations, multi-asset optimisation (EV, battery, solar, HEMS), monetisation and market access, and self-serve SaaS capabilities.
• Build and lead a high-performing product organisation - hiring, developing, and retaining Product Managers of all levels, and identifying and growing the next generation of product leaders within Flex.
• Make the trade-off calls that matter: balance the needs of our two core client segments - energy retailers and device OEMs - defaulting to retailer priorities where they conflict, in line with Flex's strategy, while protecting the long-term health of the platform.
• Partner closely with the Head of Engineering and our Commercial and Partnerships teams to align product, technical, and commercial strategy, and to make resourcing and investment decisions across Flex's product and engineering teams.
• Define annual goals and OKRs for Flex, aligned to Kaluza's company strategy, and hold your organisation accountable for delivering measurable commercial and platform-quality outcomes.
• Be the client-facing expert for Flex product: lead demos and pitches for prospective retailer and OEM clients, contribute to proposals and pricing, and represent Flex's product practice at Kaluza-wide and industry forums.
• Own the long-term roadmap narrative - kept current, accessible, and able to be told confidently to prospects and clients two years out - as well as internally to engineering, design, partnerships, and commercial teams.
• Build and maintain your network with Product, Partnership, Engineering, and Commercial leaders across Kaluza, ensuring insight from Flex feeds into - and benefits from - the wider Kaluza product strategy.
• Champion product craft and ways of working across Flex, raising the bar for discovery, prioritisation, and measurable impact, in a fast-moving, resource-constrained environment where judgement on trade-offs matters as much as vision.

Requirements

• Proven, experienced product leader with a track record of building, leading, and developing product teams and people managers, not just individual contributors.
• Seasoned expert in product strategy and execution across the full product lifecycle, with a track record of translating ambiguous, complex problems into a clear strategy and roadmap.
• Strong commercial instincts - comfortable owning pricing input, business cases, and ROI, and able to demonstrate commercial impact and business growth through your teams.
• Excellent communicator, able to present complex, ambiguous problems clearly and persuasively to technical and non-technical audiences, from engineers to clients to Kaluza's leadership team.
• Deep experience with, or a genuine ability to quickly get up to speed in, complex multi-sided B2B/B2B2C technology platforms - direct experience in energy, DER orchestration, IoT device platforms, or smart devices is a strong plus.
• Comfortable operating with high ambiguity, making the call yourself where appropriate and knowing when to escalate, in a fast-paced and frequently changing environment.
• Track record of fostering a strong product culture and coaching others - including peers without being their formal manager - to raise the standard of product work around them.
• Data-driven in how you measure impact, and able to hold yourself and your teams accountable to outcomes, not just outputs.

Nice to Have

• Experience in energy trading, national and regional flexibility markets, or other VPP monetisation opportunity spaces (e.g., balancing markets, capacity markets, wholesale/imbalance trading, ancillary services).
• Direct experience with VPPs, EV/battery smart charging, HEMS, or residential demand-flexibility products.
• Familiarity with UK and/or international energy market mechanics (e.g., BSC, NEM, market settlement, DER integration standards).
• Experience selling or supporting the sale of platform/SaaS propositions to enterprise clients.
