You've worked inside B2C retail environments, or close enough to have scars. You understand complex, high volume billing systems, whether in energy, telecoms, financial services, or subscription-based businesses. Not at a surface level, but deeply enough to hold your own with a client's Head of Billing or CTO
,
You've operated in complex enterprise sales, pre-sales, consulting, or solution architecture. You've been part of deals where the sales cycle is long, the stakeholder map is wide, and the technical evaluation is rigorous
,
You can translate technical complexity into clear, compelling narratives, whether you're whiteboarding with engineers or presenting a business case to a CFO
,
You're analytical and customer-obsessed. You reach for data before opinions and you measure what matters
,
(Desirable) Direct experience selling or implementing SaaS platforms in the energy sector
(Desirable) You've worked at or with a retailer operating at scale (millions of accounts)
,
(Desirable) You've built something from scratch before. A function, a practice, a playbook. And you enjoyed the ambiguity that comes with it
What the job involves
You'll go deep on real problems. Discovery workshops with CTOs and Heads of Billing at retailers running millions of accounts. Not surface-level demos. Proper problem decomposition, working through migration paths, integration architecture, and commercial trade-offs
,
You'll work globally. Kaluza powers OVO, AGL, ENGIE, and partners with Mitsubishi Corporation in Japan. The retailers you'll work with span Europe, Asia-Pacific, and North America. The transformation programmes are large-scale and impactful. We're talking about re-platforming core systems that touch millions of customers
,
You'll shape the product. You're not just selling what exists. You're feeding real market signal back to Product and Engineering. When three prospects in a row ask about the same gap, you're the person who turns that into a roadmap conversation
,
You'll build something from early stages. This is a growing function. You'll help define the playbook, the tooling, the demo estate, and eventually the team around you. If you want a well-trodden path with established processes, this isn't it. If you want to build the path, keep reading
,
Lead technical discovery with prospective and existing clients, understanding their current solution landscape, pain points, regulatory constraints, and target outcomes
,
Design tailored solutions that map client needs to Kaluza's platform capabilities, with a clear eye on implementation feasibility
,
Drive the technical narrative in RFP responses and proposals. Not filling in templates, but crafting compelling, credible answers
,
Negotiate scope as part of commercial discussions, balancing client ambition with deliverability
,
Support and advise our demo engineering function to ensure we build compelling experiences that bring the platform to life
,
Act as the connective tissue between what the market needs and what we build, translating client conversations into product insight
