Role OverviewWe are looking for a Senior Platform Engineer (m/f/d) to join the Data and AI Transformation Engineering team, responsible for designing and building scalable backend platforms that expose AI and automation capabilities as reliable, production grade services.The role focuses on developing API driven systems deployed on Kubernetes, combining AI driven components with deterministic logic to support complex transformation and automation use cases across multiple business units. Operating in a regulated financial services environment, the role requires a strong engineering mindset with compliance, governance, and responsible use of AI treated as core design principles.What You DoDesign and maintain RESTful APIs with robust versioning strategies, ensuring stability as model behaviour evolves across releases.Define structured, validated response schemas that deliver deterministic, auditable outputs suitable for enterprise consumption.Implement streaming response patterns (SSE / chunked HTTP)



to enable real-time model output delivery to frontends and downstream systems.Implement authentication and authorization frameworks (OAuth 2.0, JWT, RBAC, scopes) including service principal patterns for cloud-to-cloud integration across Azure, AWS, and Databricks.Enforce data controls at the API layer — including input sanitisation, output filtering, and guardrails — ensuring responses meet compliance standards before leaving the system.Build audit logging into the API contract so that every request and response is fully traceable for regulatory purposes.Design background job patterns that return immediately to callers while model inference executes asynchronously.Integrate with message queues and event-driven architectures (Azure Service Bus, SQS, Kafka) for pipeline orchestration.Implement polling and webhook callback mechanisms to deliver results without blocking consumers.Establish structured logging on every API call — capturing inputs, outputs, latency, and model v
