We want the best people

We're keen to meet people from all walks of life - our view is that the more inclusive we are, the better our work will be. We want to build teams which represent a variety of experiences, perspectives and skills, and we recognise talent on the basis of merit and potential.

Kaluza is the Energy Intelligence Platform. We help energy companies manage complexity in real time - orchestrating decisions across homes, grids, EV charging and energy markets. We work with OVO, AGL, ENGIE, Volvo and Volkswagen, with teams across Europe, North America, Asia and Australia. Our People and Finance teams are at the heart of how Kaluza operates, and we think AI is going to fundamentally change what's possible for both functions. We're looking for a People & Finance Systems Developer to be at the centre of that change. Working closely with both teams, you'll help identify where AI can make the biggest impact and build the tools to make it happen. This is a hands-on role where you'll own your solutions from the initial idea to the live AI-powered production system. What will I be doing? * Design, build and deploy AI-powered workflows using modern agentic LLMs (Anthropic, Gemini) to genuinely transform how our People and Finance teams work. * Partner closely with stakeholders in People and Finance teams to understand their challenges, build solutions, and iterate based on feedback. * Integrate AI capabilities into the tools our People and Finance teams use every day, from Workday and Greenhouse to Slack, Jira, and Google Workspace. * Be a genuine advocate for AI adoption across People and Finance, helping the team build confidence and use it effectively and responsibly.
