Software Engineer - Energy

Hi! We're UW. We’re on a mission to take the headache out of utilities by providing them all in one place. One bill for energy, broadband, mobile and insurance and a whole lot of savings!

We’re aiming to double in size as we help more people to stop wasting time and money—big ambitions, to be delivered by people like you.

We work together. Your team and the people you will work with…

We work in small, fully autonomous teams with real ownership of their products.

Energy is at the heart of UW, with over 95% of our customers taking at least 1 Energy service. As a Software Engineer in the Energy team, you'll find yourself working on high-impact projects such as our ongoing Energy Transformation and Market Wide Half Hourly Settlement - projects which lay the foundation for the next phase of UW.

You'll be joining one of our Energy engineering teams - the driving force behind our Energy Transformation. Working primarily with Go, Postgres, Kafka & Kubernetes, you'll contribute to the systems which underpin our Energy product offering.

We put people first. It’s all about you…

We’re looking for a backend-focused engineer to work across our core energy platforms. You’ll support end-to-end deployments within our team’s Kubernetes namespaces, contributing to delivery while collaborating with senior engineers. You’ll help build and operate systems where resilience, reliability, observability, and uptime are important to the team’s success.

You’ll thrive here if you enjoy autonomy and solving distributed systems problems. Collaboration, pragmatism and low-ego teamwork are essential.

Required Skills and Experience

To be successful in this role, you’ll need:

• Strong, hands-on production experience with Go (non-negotiable)
• Proven fluency with Postgres, Kafka, and Kubernetes
• Solid experience building distributed systems, including concurrency and event-driven architectures
• A strong understanding of system resilience, observability, uptime, SLAs, and progressive degradation
• The ability to deliver end-to-end solutions, from design through build, deployment, and ongoing support
• Experience working with CI/CD tooling, Terraform, and modern cloud workflows
• Familiarity with Kafka and database migrations (e.g. CockroachDB to RDS) as a plus
• Strong communication, collaboration, and problem-solving skills
• The ability to thrive in an agile, iterative environment while delivering continuous feature improvements
• Experience mentoring mid-level engineers and modelling engineering best practices
• Comfort working in autonomous, product-focused teams

We deliver progress. What you’ll do and how you will make an impact.

Impact: Contribute to team goals by delivering well-scoped work that aligns with agreed objectives. Participate in prioritisation discussions and raise risks or opportunities as they arise.

Technical Skills: Design and implement reliable technical solutions within existing architectures and standards. Make sound technical decisions for your work, drawing on experience across relevant technologies and seeking guidance when needed.

Planning & Delivery: Deliver features and improvements from design through to completion with support from senior engineers. Balance quality and progress, address technical debt as part of regular work, and help keep services and processes maintainable.

Business & Domain Knowledge: Build a solid understanding of the product and services your team supports. Understand how your work contributes to user and business outcomes, and factor this into day-to-day technical decisions.

Collaboration & Growth: Work collaboratively through pairing, code reviews, and team discussions. Be open to feedback, support teammates when possible, and actively develop your technical and professional skills.
