ROLE SUMMARY Sits within a newly acquired startup building an AI-enabled, autonomous banking platform for Tier-1 financial institutions within the banking group. The role builds, operates, and scales the services at the heart of the platform — spanning Core Banking, workflows, and compliance. These systems define financial products, manage accounts, execute and record money movement, orchestrate banking processes, and enforce regulatory rules at Tier-1 scale. Requires deep experience with complex distributed systems, a correctness-first mindset, sound engineering judgement, and full end-to-end ownership from design through production operation. KEY RESPONSIBILITIES Banking Platform Engineering Build and evolve the capabilities that bring modern banking products to life — from products and accounts through transactions, transfers, journals, balances, and interest, to durable workflows and compliance controls. Define reliable APIs, events, and data contracts that connect these capabilities into a coherent, auditable banking platform. Production Ownership Own services throughout their lifecycle: design, implementation, testing, deployment, operation, and continuous improvement. Participate in on‑call and incident response, diagnosing failures across distributed services, data infrastructure, and event‑driven workflows. Establish effective observability, alerting, operational controls, and recovery procedures; learn from production incidents to improve reliability, performance, and operational maturity. Architecture and Delivery Design systems for correctness, auditability, scalability, and resilience at Tier‑1 banking scale, making pragmatic trade‑offs between delivery speed, operational complexity, and long‑term maintainability. Improve engineering practices across automated testing, CI/CD, safe deployment, rollback, and recovery. Use AI‑assisted engineering, MCP servers, agent workflows, and automated runbooks where they materially improve engineering or operational outcomes. Contribute to team excellence through knowledge sharing, mentoring, and coaching, helping to develop technical capability and promote engineering best practices across the organization. REQUIRED EXPERIENCE a relatively small portion of our hiring is through recruitment agencies. FIS does not accept resumes from recruitment agencies which are not on the preferred supplier list and is not responsible for any related fees for resumes submitted to job postings, our employees, or any other part of our company.
