These systems define financial products, manage accounts, execute and record money movement, orchestrate banking processes, and enforce regulatory rules at Tier-1 scale.\nRequires deep experience with complex distributed systems, a correctness-first mindset, sound engineering judgement, and full end-to-end ownership from design through production operation.\nKEY RESPONSIBILITIES\nBanking Platform Engineering\nBuild 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.\nDefine reliable APIs, events, and data contracts that connect these capabilities into a coherent, auditable banking platform.\nProduction Ownership\nOwn services throughout their lifecycle: design, implementation, testing, deployment, operation, and continuous improvement.\nParticipate in on-call and incident response, diagnosing failures across distributed services, data infrastructure, and event-driven workflows.\nEstablish effective observability, alerting, operational controls, and recovery procedures; learn from production incidents to improve reliability, performance, and operational maturity.\nArchitecture and Delivery\nDesign 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.\nImprove engineering practices across automated testing, CI/CD, safe deployment, rollback, and recovery.\nUse AI-assisted engineering, MCP servers, agent workflows, and automated runbooks where they materially improve engineering or operational outcomes.\nContribute to team excellence through knowledge sharing, mentoring, and coaching, helping to develop technical capability and promote engineering best practices across the organization\nREQUIRED EXPERIENCE & CAPABILITIES\nEngineering Depth\nDeep experience designing and building complex distributed systems at scale, using a strongly typed, compiled language. Go is preferred, but deep experience with a comparable language is welcome.\nExperience with event-driven architectures and technologies such as Kafka or equivalent streaming platforms.\nStrong understanding of concurrency, consistency, invariants, idempotency, failure modes, and distributed-system trade-offs.\nProduction Experience\nSubstantial experience operating and debugging critical systems in production, ideally including on-call and incident response across application, data, and infrastructure boundaries.\nPractical experience with observability, reliability engineering, capacity planning, deployment safety, and disaster recovery.\nExperience with automated testing, CI/CD, GitOps, and modern production-engineering practices.\nJudgement and Communication\nPractical judgement and common sense, with the ability to evaluate and clearly articulate architectural trade-offs rather than apply technologies or patterns mechanically.\nAbility to explain complex systems in simple, precise terms and work effectively across coding, architecture, operations, and cross-team delivery.\nEffective use of AI to amplify genuine engineering expertise, with human ownership of design, validation, security, and production outcomes.\nIMPACT & SCOPE\nDirect impact on core banking capabilities shipped to and supported in production for Tier-1 global institutions.\nHigh autonomy and accountability within a small, senior team.\nOwnership of mission-critical systems operating at enterprise scale.\nWHY THIS ROLE\nThis role offers the autonomy, ownership, and technical depth of a startup, combined with the scale, stability, and long-term impact of FIS. Engineers in this role shape foundational banking infrastructure while operating with clear accountability, enterprise resources, and real-world production responsibility.\nFIS is committed to providing its employees with an exciting career opportunity and competitive compensation.
