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.

The challenge

For our Customers and Partners, UW just needs to work – there when you need it, and invisible when you don't. Just like flicking a switch.

Our proposition to customers is simple, but for our technology teams, the behind the scenes complexity is what makes it so interesting. Learn more about life in our Tech teams.

We put people first. It's all about you

The ideal candidate is someone who has a strong background in building and maintaining software and microservices within an event-sourced architecture. They should be proficient in Golang and have hands‑on experience with technologies such as Kafka, PostgreSQL, AWS, and Terraform. This role requires a problem‑solver who can design, implement, and optimise scalable data contract frameworks and abstraction tools that integrate with our internal CRM, while ensuring the reliability and performance of existing systems. The ideal candidate thrives in a collaborative environment, working closely with software engineers and product teams to deliver robust, high‑quality solutions. Previous Rust exposure or interest to develop is highly desired.

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

We work in small, fully autonomous teams that have real ownership of their products. We use the best tool for the job and constantly look for better.

The Data Infra team delivers & maintains strategic tools that are used by multiple internal teams and covers two major product areas:

• A standard framework and platform for the definition, creation and maintenance of data products. It enables ELT processes from standard sources (i.e. databases, Kafka, APIs etc.) to our warehouse (BigQuery) while supporting the toolset for data contract definition and maintenance.
• Integration software and abstraction tools between Golang applications running on Kubernetes and our internal CRM. These are developed in Golang, some are using Rust and are at the core of internal application communication between domain team applications and the internal CRM.

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

We are looking for a software engineer with experience in planning and implementing software and microservices within an event-sourced architecture. This role is essential for maintaining and developing UW's data product framework and will involve collaborating with a team of software engineers and product managers.

What you'll do

• Are comfortable diving into an area that they're not familiar with and making changes.
• Keep simplicity at the core of their workflow, reducing unnecessary complexity.
• Evaluate and propose multiple approaches to a problem, understanding the wider business implications of each.
• Take a complex user story, break it down into sub‑tasks, and complete them with minimal oversight.
• Identify and communicate project risks to their team and stakeholders.
• Set, monitor and uphold standards for their team's workflow, documentation, security and quality of code.
• Create and advocate for the technical roadmap of their team and area.
• Run technical team meetings and drive them to actionable outcomes.
• Review pull requests from engineers of a wide range of skills and abilities.
• Mentor and provide guidance to junior engineers.

So why pick UW?

We've got big ambitions so there's going to be plenty of challenges. There are also a lot of benefits:

• An industry benchmarked salary. We'll share it during your first conversation.
• Share Options and Save as You Earn scheme.
• Discount on our services and you get our coveted Cashback Card for free.
• A matched contribution pension scheme and life assurance up to 4x your salary.
• Family‑friendly policies, designed to help you and your family thrive.
• Discounted private health insurance, access to an Employee Assistance line and a free Virtual GP.
• Belonging groups that help UW shape an even more inclusive future.
• A commitment to helping you develop and grow in your role.
