Senior C# Software Engineer

Responsibilities

You’ll work with C#, Kafka, Kubernetes, Docker, AWS Aurora Postgres, and other modern technologies. If you haven’t worked with all of these, we value skilled engineers with a willingness to learn. We’ll support your transition and cross‑training into a JVM/Kotlin environment.

You’ll design and evolve the services that power core banking products. The systems you help build process thousands of financial transactions every day and must be scalable, resilient, and secure. When money moves, it has to work – every time. You will shape technical direction, influence cross‑team initiatives, own complex, high‑impact work from concept through to production, and help decide not just how we build, but what we build and why.

• Own complex initiatives end to end, from idea to measurable outcome.
• Design scalable backend systems that stand up to real‑world scale and complexity.
• Make architectural decisions that balance immediate delivery with long‑term sustainability.

Qualifications

• Track record of delivering high‑impact, complex systems in production environments.
• Strong testing discipline and commitment to strictly following Test‑Driven Development (TDD).
• Strong systems thinking and architectural judgement.
• Ability to navigate ambiguity and turn complexity into clear, actionable plans.
• Confidence making data‑informed technical decisions with long‑term consequences in mind.
• Experience influencing beyond your immediate team.
• Deep customer focus and bias toward measurable outcomes.
• Experience mentoring others and amplifying team impact.
• Ownership beyond your own output.
• Willingness to learn and adapt to new technologies if not familiar with all listed tools.
• Experience with fintech or banking is a plus, but problem‑solvers from all backgrounds are valued.
