Engineer II - API Platform Team

Kaluza reimagines energy to bring net-zero within everyone’s reach. The Kaluza 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.

You'll be joining the Kaluza Technology community. We’re a diverse group of both data-led and product-focused engineers, pushing the boundaries of technology and working at an extraordinary scale. We strive for engineering quality & innovation, continuously improving our best practices across our highly collaborative community.

The API Platform team is a newly combined team of software engineers within the Client Integrations squad responsible for building & supporting the retail platform-critical components of Kaluza’s Graph

QL API (KaPI) & event gateway (KEG) solutions. Our vision is that Kaluza is the easiest, most intuitive retail platform with which to integrate - our API Platform sits alongside our other large-scale analytical offering (KDM) to provide a coherent, low latency way for retail clients to maintain and find their data.

The team is well-distributed across the UK so we operate as a remote-first team, although we do organise physical meet-ups every 6-8 weeks in our London, Edinburgh or Bristol offices for workshops & fun.

Core technology-wise, we use Scala, Graph

QL and Dynamo

DB, alongside Kafka & Avro. We deploy on to our internal Kubernetes platform with Terraform & Aiven as our IaC and Git Hub for code repositories and workflows.

As an engineer within the API Platform team, you’ll play a crucial part in both developing and support the KaPI and KEG products; in particular:

• Working on a mixture of discovery/spike tasks, tech debt and core delivery tickets on our backlog
• Providing in-hours support for KaPI and/or KEG as part of our team rota
• Playing an active part in our team’s weekly planning, daily stand-ups and regular ops health, backlog refinement and retros

There will also be opportunities to…

• Join in on our squad’s innovation time (and/or Kaluza innovation time)
• Get involved in our team meet-ups & socials, and squad events (e.g. Coffee & Donuts sessions, in-office meet-ups)
• Pair or swarm on improving shared services/products, such as kpi-config
• Represent our team at squad or engineering community level (e.g. Platform health reviews, post-mortems, etc)

For this role it’s essential that you have:

• Backend and/or full stack development experience
• Experience with Scala
• Evidence of working with a breadth of tooling from CI/CD pipelines to Infrastructure As Code.
• Evidence of proactively & independently solving problems, as well evidence showing your ability to pair on development or problem-solving tasks
• An enthusiasm to learn new technologies and about new domains

It would also be advantageous, but not essential, that you have some of:

• Awareness of core SRE concepts such as disaster recovery and platform health monitoring
• Experience with building, deploying & monitoring AWS components
• Experience with Kubernetes hosted components
• Experience working with Kafka & Avro
• Experience working with DynamoDB
• Software design, service architecture and/or technical options analysis

Here at Kaluza we have five core values that guide us as a business:
