About FIS
At FIS, our technology and our people are moving forward. We advance the way the world pays, banks and invests. We believe in building inclusive, diverse teams. Together, we innovate to help our colleagues, clients and communities succeed. If you’re ready to grow your career and make an impact in fintech, we have one question: Are you FIS?
About the Role
We are seeking a highly technical Senior AI Engineer to lead the development of our next-generation banking customer experience by building real-time, conversational Agentic AI voice systems from the ground up.
Above all else, your primary skill must be an insatiable curiosity to learn, deconstruct, and implement emerging systems. The generative AI landscape evolves weekly, and this role requires a relentless drive to experiment with novel architecture, ingest new research, and translate bleeding-edge concepts into production-grade banking solutions.
This role will focus on building production-grade, multi-agent solutions that combine deterministic workflow control with LLM-driven reasoning, real-time speech interaction, secure API integration, and measurable business outcomes.
The ideal candidate brings deep software engineering expertise, strong curiosity for emerging AI architectures, and the ability to translate rapidly evolving agentic AI capabilities into reliable, compliant, and scalable financial technology solutions.
What You Will Be Doing
Architect and deliver enterprise-scale Agentic voice AI systems that combine deterministic workflow control, LLM-driven reasoning, tool orchestration, memory management, and secure API integration across regulated banking use cases.
Build production-grade Agentic AI solutions that integrate speech-to-text, text-to-speech, LLMs, cognitive services, and backend enterprise systems to deliver natural, reliable, real-time customer interactions.
Design agentic workflows that enable AI systems to complete complex, multi-step tasks using structured planning, function calling, tool routing, state management, and human-in-the-loop escalation where appropriate.
Optimize real-time voice interactions for low latency, reliability, scalability, and cost efficiency through streaming architecture, token optimization, semantic caching, prompt tuning, and performance engineering.
Deploy highly available AI services using cloud-native architectures across Azure and AWS, including Kubernetes, container platforms, serverless services, multi-region resilience, and secure DevOps practices.
Build evaluation, experimentation, and observability frameworks to measure conversational quality, routing accuracy, latency, containment, hallucination risk, tool-call reliability, and production performance.
Implement security, privacy, Responsible AI, and compliance guardrails to protect sensitive customer data and ensure AI systems operate within financial-services regulatory expectations.
Troubleshoot complex issues across distributed AI systems, including network latency, model behavior, prompt failures, token-limit breaches, API errors, orchestration defects, and non-deterministic agent outcomes.
Collaborate with product, architecture, engineering, cloud, data, security, and business teams to translate business requirements into scalable AI solutions.
Mentor engineers in AI-first software engineering practices, including reusable component design, automated testing, defensive programming, observability, deployment discipline, and production support.
