This role is based in London, Bristol or Edinburgh and requires an existing right to work in the UK.

At this time, we are not able to offer visa sponsorship for this role. We are committed to building a diverse, global team and our sponsorship policy is evaluated on a role-by-role basis. We encourage you to keep an eye on our careers site to stay informed about future opportunities where we are able to offer visa sponsorship.

What will I be doing?

  • Own the People service desk queue day-to-day: triaging, responding to, and resolving employee queries, and keeping response times and queue health on track.
  • Continuously improve our Jira Service Desk itself - refining triage, workflows, and automations - and feed recurring ticket themes back into our People Bot's knowledge base, so the answers people get before they ever need a human just keep getting better.
  • Be the main point of contact for new joiners between offer and day one, partnering with Talent Acquisition to make pre-boarding seamless and ensuring nothing falls through the cracks.
  • Own and continuously improve the onboarding experience end-to-end - from offer acceptance to day one and beyond - so every new hire feels genuinely welcomed and set up for success.
  • Support payroll inputs, benefits administration, and compliance activities, making sure our processes hold up against internal policy and employment law requirements.
  • As you grow into the role: help audit and redesign People processes, identifying where automation, AI, or self-service can reduce manual effort and put information directly in employees' hands.
  • Roll up your sleeves on cross-functional People projects as they come up - whether that's a Reward cycle, a hiring initiative, or an experience improvement.

About You

Ideally, you'll have/be:

  • Some experience in a People Operations or HR administrative role, with a genuine interest in how operational rigour underpins the employee lifecycle.
  • Hands-on comfort with a HRIS, ideally Workday - confident entering and updating records accurately as part of onboarding and lifecycle admin, even if deeper reporting and analysis isn't your focus.
  • A naturally curious, detail-oriented approach to data - happy to flag something that looks off, even while you're still building the experience to know exactly why.
  • Some exposure to payroll input processes, or strong eagerness to learn them, with the attention to detail accurate processing demands.
  • Some experience administering employee benefits (enrolment, changes, queries), and comfortable being a point of contact when something needs sorting.
  • A habit of noticing when a process is clunky and saying so - you don't need to have led a full redesign yet, but you think about why something works the way it does.
  • Experience using a service desk tool (Jira or similar) to manage and triage a queue, with a good instinct for keeping things moving and knowing what needs escalating.
  • Awareness of compliance and employment law basics, and the judgment to flag rather than guess when something feels off.
  • Clear, warm communication - equally comfortable writing to a nervous new joiner as flagging something to a manager.

What will set you apart:

  • You're curious about what AI and automation can do for People Operations, and you're already poking at tools and forming opinions rather than waiting to be told to explore what's next.
  • You hold yourself to a high bar, and you'll say so if you think something could be better - even if you're not yet the one leading the fix.
  • You share what you know and keep people in the loop - a new joiner never feels like they're chasing you for answers.

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.

About Kaluza

Company Overview

Name

Kaluza

Headquarters

London, England, United Kingdom

Founded

2019

Size

Approximately 50 employees (source: linkedin.com). Revenue figures are not publicly disclosed as Kaluza remains privately held without a parent company beyond its OVO origins and key shareholders like AGL and Mitsubishi Corporation through joint ventures.

What They Do

Kaluza is a London-based energy software company that specializes in a real-time SaaS platform designed to optimize energy operations, integrate smart devices, and support decarbonization for utilities worldwide. The company was launched as a spin-out from OVO Energy, which recognized the need for a platform capable of managing smart meter data, EV chargers, solar inverters, and dynamic tariffs to facilitate the sustainable energy transition. Kaluza's technology is built on a cloud-native, modular architecture that leverages AI-driven forecasting to enable dynamic load balancing and renewable integration, making it a pivotal player in the energy sector (source: sustainabletimes.co.uk).

Projects & Track Record

Kaluza has made significant strides in the energy sector, notably powering OVO's acquisition of a large UK incumbent, which allowed it to consolidate tech stacks and become the UK's fourth-largest energy provider. The company manages over six million meters and has successfully delivered over 100 GWh of load optimization through its innovative tariffs. Major ongoing projects include deploying its platform for AGL Energy in Australia, following a substantial $100 million investment and licensing agreement, as well as a joint venture with Mitsubishi Corporation aimed at enhancing energy solutions for utilities and automakers in Japan. Additionally, Kaluza signed a multi-year global agreement with Engie in September 2025, which will enable real-time intelligence for distributed energy resources across Engie's extensive consumer contracts (source: eurelectric.org).

Recent Developments

In June 2024, Kaluza secured a $100 million investment and licensing deal from AGL Energy, which significantly boosted its valuation to $500 million. This investment is particularly timely, given the current volatility in energy prices and the growing demand for EV and solar solutions. Shortly thereafter, Kaluza launched a joint venture with Mitsubishi Corporation to expand its operations in Japan, targeting utilities and automakers. In September 2025, the company further solidified its market position by signing a multi-year global agreement with Engie, which followed a rigorous technology evaluation process. This agreement will facilitate the optimization of distributed energy resources across Engie's markets, showcasing Kaluza's leadership in the energy transformation space (source: kaluza.com).

Working There

Kaluza offers a dynamic work environment with roles spanning engineering, product development, commercial/sales, operations, and sustainability. The company is focused on building teams that specialize in various platform modules, including energy optimization, billing, customer care, and data intelligence. Recent leadership additions, such as a Chief Commercial Officer, reflect Kaluza's commitment to expanding its teams in key markets like the UK, Australia, Japan, and the US. The company culture is mission-driven, emphasizing innovation and a shared goal of accelerating the clean energy transition. Kaluza's B Corp certification and commitment to net zero by 2030 further illustrate its dedication to purpose-led operations (source: kaluza.com).
