Kaluza reimagines energy to bring net-zero within everyone’s reach. Our intelligent platform enables energy utilities to unlock the full value of a radically changing energy system and propel us to a future where renewable energy is sustainable, affordable and accessible for all. 

From automating and simplifying core operations including billing to create a lower-cost, higher-engagement experience, to optimising energy usage across smart devices in the home, we turn tough challenges into win-win-win outcomes for customers, suppliers and the energy system. 

At Kaluza we embrace a flexible, hybrid work model that balances autonomy with the power of in-person connection. Many of our teams find value in coming together regularly to collaborate, strengthen relationships, and accelerate progress. We’re focused on shaping thoughtful, team-driven approaches that support both business impact and individual well-being.

We also prioritise meaningful company-wide gatherings like our annual conference and end-of-year celebrations, that bring us together to align, connect, and celebrate.

What will I be doing?

A technical leader in our Deployment Design team, you will be responsible for designing bespoke target architectures for our clients. You will understand the best approaches for deploying the Kaluza platform into our clients’ technology landscapes, how best to integrate with existing and new systems via modern / progressive methods, and how to maximise the potential of Kaluza’s software.

You will be a key member of the Deployment Design team: a specialist unit focused on winning Kaluza new business and then delivering on the deals made. The team’s mission is to create seamless, scalable, and secure deployment solutions that empower our clients to accelerate innovation, achieve operational efficiency and business success. Through collaboration, a focus on repeatability, and a user-centred approach, we design and implement reliable SaaS deployment architectures that enhance performance, minimise risk, and support future growth.

As well as exceptional technical skills, you must have an acute commercial understanding of technology-based transformations, including contributing to business case development, the ability to solve complex problems and make well-reasoned recommendations to stakeholders who are both technical and non-technical.

Responsibilities:

• Future state architecture design for new and existing clients
• Leading technical and architectural elements of commercial proposals
• Active participation in Kaluza architecture community - driving best practices
• Leading technical efforts within overall deployment and implementation design
• Developing technical documentation both specific to a client implementation and for use in Kaluza as playbooks helping standardise future Kaluza deployments
