• Proficient in RESTful API design and consumption, with secure authentication and authorisation practices (OAuth, JWT).
• Solid SQL Server/database skills, including data modelling and query optimisation for high-throughput financial systems.
• Experience working in regulated banking or fintech environments, applying best practices in code and data security.
• Confidence with Git, agile software workflows, and collaboration tools (Jira, Confluence, Azure DevOps).

• Familiarity with cloud-native development (Azure, AWS) in financial workloads.
• Knowledge of event-driven or messaging systems (Kafka, RabbitMQ, Azure Service Bus) for high-performance financial applications.
• Experience integrating with FIX protocol, SWIFT, or real-time financial data feeds.
• Domain-driven design, microservices, and containerisation (Docker, Kubernetes) in a banking or trading context.
• Understanding of regulatory reporting, compliance systems, or risk/valuation engines is a bonus.

Work Model
