  • Strong SQL and relational database knowledge.

  • Production troubleshooting and debugging.

  • Observability, monitoring, logging and alerting.

  • AWS and/or Azure.

  • Docker and Kubernetes.

  • CI/CD and automated testing.

  • Software design principles, design patterns
    and clean architecture.

  • Scala or other JVM technologies considered.

  • Strong .NET engineers considered with distributed systems experience.

    What We’re Looking For

  • End‑to‑end systems understanding.

  • Experience with production systems at scale.

  • Ability to diagnose complex problems independently.

  • Knowledge of scalability, resilience, failure handling and performance.

  • Ownership of system reliability and production performance.

  • Ability to mentor and support engineers.

  • Clear communication with technical and business stakeholders.

    Banking / Payments Experience

  • Experience in banking, payments, fintech or high‑volume financial environments advantageous.

  • Other large‑scale, distributed, transaction‑heavy or business‑critical systems experience considered.

    Ideal Candidate
