The role

We are looking for a highly motivated senior backend Engineer to join our Platform & Infrastructure team. You will take ownership and drive the evolution of our mission-critical platform and services, recognising that platform is the product for our engineers. You’ll contribute to the technical roadmap, lead hands‑on implementation and ensure operational excellence across our backend foundation, focussing on simplicity, scalability, performance and security. We require someone passionate about defining best practices, mentoring others and developing systems that allow our product teams to move quickly and reliably in a high‑growth environment.

What you’ll do

• Design, implement and maintain core platform services and tools that enhance developer productivity, reliability and security for all engineering teams.

• Help drive the technical roadmap for our cloud infrastructure, promoting architecture principles focused on simplicity, scalability, and cost efficiency.

• Establish and advocate for best practices in areas like CI/CD pipelines, observability (logging, metrics, tracing), and automated testing to ensure operational excellence.

• Lead the resolution of complex production incidents and proactively identify and mitigate reliability and performance bottlenecks across our platform foundation.

• Mentor and guide product engineers on proper platform usage, architectural patterns, and operational best practices, embodying the "platform is the product" mindset.

What You’ll Bring

• Extensive experience operating production systems in a high availability, cloud environment.

• Deep expertise in a strongly typed language and the ability to quickly deliver value in C#.

• Practical experience with Infrastructure as Code tools, like Terraform.

• Proficiency in modern build and deployment processes, including automated, progressive continuous deployments.

• A proven track record of building robust, reliable systems with a strong focus on observability and operational excellence.

• Experience with containerization and orchestration technologies, including Docker and Kubernetes.

• Strong foundation in networking and security best practices.

Who you are

• United - you focus on “we” over “me”, you lead your team and colleagues to solve problems together.

• Unstoppable - action orientated, you get going, embrace challenges, provide clarity in ambiguity and elevate everything around you to new levels.

• Useful - You focus on solving real problems for our customers, you consistently look to innovate and are not limited by the 'scope' of your role.
