Company Description

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. Got your attention? Read on…

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 Senior 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 our Products, Tariffs and Discounts team - a key part of our Energy Transformation. Working primarily with Go, Postgres, Kafka & Kubernetes, you'll contribute to our tariff management platform, which underpins our Energy product offering.

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

We’re looking for a senior backend-focused engineer to work across our core energy platforms. You’ll own deployments end-to-end within our team’s Kubernetes namespaces and contribute to systems where resilience, reliability, observability and uptime really matter. You’ll thrive here if you enjoy autonomy, solving distributed systems problems, and mentoring others as a player-coach. Collaboration, pragmatism and low-ego teamwork are essential.

Required Skills and Experience

  • 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 (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.

Senior Software Engineer Responsibilities (Based on our Engineering Career Progression Framework):

  • Impact: Be integral in defining team goals, ensuring proposed work aligns with our objectives and driving prioritisation to best achieve them.
  • Technical Mastery: Design and implement complex technical solutions that align with our strategy, influencing guidelines and standards across the wider engineering group. Take responsibility for technical decisions within your team, demonstrating expertise across multiple technologies.
  • Planning & Delivery: Own large technical features from design to completion, making well-informed trade-offs between progress and perfection. Provide technical direction to your squad, proactively tackling debt and reducing complexity in our services and processes.
  • Business & Domain Knowledge: Develop a high-level understanding of our multi-service business model, leading discussions on how your squad’s work contributes to the broader company strategy.
  • Leadership & Culture: Teach our culture to others and mentor engineers via pairing and code reviews, fostering collaboration where all voices are heard. Lead complex projects and discovery into unknowns, working well under pressure to drive the team forward.
