Descripción de la vacante

Kernel is building the backend services behind its investment platform in Auckland, designed to serve tens of thousands of Kiwi savers. You’ll design, build and run backend services in C# and .NET on AWS, owning your work from sketch to production in a small, collaborative team.

We value clear, testable code, strong API design and a hands-on approach to building scalable systems. If you enjoy solving hard problems with pragmatic, reliable software, this role is for you.

Formación

• Commercial experience building backend systems in production.
• Strong C# and .NET skills with a keen interest in functional programming concepts.
• Cloud-native experience, ideally in AWS (Azure counts too).
• Experience with NoSQL databases such as DynamoDB, not just relational SQL.

Responsabilidades

• Design, build and operate the backend services, APIs and integrations behind KiwiSaver, investing and savings at Kernel
• Own your work end-to-end, from planning and design through to running it reliably in production
• Write clean, functional-style C# that favours correctness, clarity and testability over shortcuts
• Build on our AWS serverless architecture, including Lambda and DynamoDB
• Work across both monolithic and microservice architectures, and help shape how our systems evolve as we grow
• Own quality, building in testing and observability from day one, with QAs who coach rather than test for you
• Plan thoroughly with your team, then ship often in small, valuable milestones, using feature flags where needed
• Share what you know through code reviews and pairing, and help the engineers around you grow
• Partner with Product and Design to turn customer problems into reliable, well-built features
