Job description

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.

The Customer Experience team is responsible for the main page of the web app, the main screen of the mobile app, navigation, and the overall information architecture that connects our services into clear, end-to-end user journeys.

This team integrates the work of other product teams, requiring a strong understanding of how applications fit together and how people, processes, and data flow across the platform. You’ll collaborate closely with other teams to deliver cohesive, high-quality experiences.

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

We’re looking for a Senior Frontend Engineer to work across our core Customer Experience platforms.

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 experience in Web React/ Next.js apps (using TypeScript)
• Strong knowledge of developing mobile apps using React Native
• Experience with CI/CD tools and practices
• Collaborative approach to ensure quality design and practices
• Familiarity with GraphQL or willingness to learn
• Experience in test automation
• 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

Senior Software Engineer Responsibilities

• 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.
