Senior Software Engineer - Partner

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.

Partner is at the heart of UW’s growth, enabling thousands of Partners to introduce new customers to our services. As a Senior Software Engineer in the Partner team, you’ll work on products that support every stage of the partner journey—from onboarding and lead management to helping Partners grow and run their businesses. You’ll have the opportunity to shape new initiatives while continuously improving existing experiences through experimentation and data-driven decision making.

You’ll be joining one of our Partner engineering teams, building the platforms and services that power our Partner proposition. Depending on the team, you’ll contribute to systems such as our Lead Platform, which intelligently routes leads to Partners, or the journeys that help Partners join UW, schedule appointments, and manage their business across our web and mobile applications. Working primarily with Go, Postgres, Kafka and Kubernetes, you’ll build scalable, reliable systems that support one of UW’s most important growth channels.

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

We’re looking for a senior backend-focused engineer who enjoys building scalable platforms and solving complex business problems. You’ll own deployments end-to-end within your team’s Kubernetes namespaces and help deliver services that are reliable, observable and resilient.

You’ll thrive here if you enjoy taking ownership, working across distributed systems, and collaborating closely with product managers, designers and engineers to deliver meaningful outcomes. Whether you’re improving lead routing, simplifying partner onboarding or enabling new Partner propositions, you’ll combine technical excellence with a pragmatic, low-ego approach while mentoring others as a player-coach.

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.
