Senior/Staff Software Engineer
About The Position
This role is part of a newly acquired startup within FIS, building an AI-enabled autonomous banking platform for Tier-1 financial institutions. The engineer builds, operates, and scales services across 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. The role requires deep experience with complex distributed systems, a correctness-first mindset, sound engineering judgment, and end-to-end ownership from design through production operation. The position offers high autonomy and accountability within a small, senior team, with direct impact on core banking capabilities shipped to and supported in production for Tier-1 global institutions. It combines startup-level autonomy, ownership, and technical depth with FIS’s scale, stability, enterprise resources, and long-term impact.
Requirements
- Deep experience designing and building complex distributed systems at scale using a strongly typed, compiled language.
- Experience with event-driven architectures and technologies such as Kafka or equivalent streaming platforms.
- Strong understanding of concurrency, consistency, invariants, idempotency, failure modes, and distributed-system trade-offs.
- Substantial experience operating and debugging critical production systems, ideally including on-call and incident response across application, data, and infrastructure boundaries.
- Practical experience with observability, reliability engineering, capacity planning, deployment safety, and disaster recovery.
- Experience with automated testing, CI/CD, GitOps, and modern production-engineering practices.
- Ability to evaluate and clearly articulate architectural trade-offs using practical judgment.
- Ability to explain complex systems in simple, precise terms and work across coding, architecture, operations, and cross-team delivery.
- Ability to use AI to amplify engineering expertise while retaining human ownership of design, validation, security, and production outcomes.
Nice To Haves
- Go experience; deep experience with a comparable strongly typed, compiled language is also welcome.
Responsibilities
- Build and evolve banking capabilities spanning products, accounts, transactions, transfers, journals, balances, interest, durable workflows, and compliance controls.
- Define reliable APIs, events, and data contracts that connect platform capabilities into a coherent, auditable banking platform.
- Own services throughout their lifecycle, including 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 observability, alerting, operational controls, and recovery procedures, and use production incidents to improve reliability, performance, and operational maturity.
- Design systems for correctness, auditability, scalability, and resilience at Tier-1 banking scale.
- Make pragmatic trade-offs among delivery speed, operational complexity, and long-term maintainability.
- Improve engineering practices for 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.
- Share knowledge, mentor and coach colleagues, develop technical capability, and promote engineering best practices across the organization.
