Principal Solution Architect, Platform Engineering

Job Description

About the role

Reporting to the Head of Architecture for Platform Engineering, the Principal Solution Architect plays a crucial role in designing and delivering enterprise platform capabilities. Platform Engineering is chartered to deliver the shared capabilities that product engineering teams use to deliver secure, reliable, performant, high-quality products to clients faster.

Platform Engineering’s portfolio spans AI Engineering, API & Event Management, Front End, Site Reliability Engineering (SRE), Developer Experience & Quality, and Customer Identity & Access Management.

This role’s primary focus is public cloud enablement, the foundation that every platform and product in the enterprise will build on. You will architect how public cloud environments are vended, provisioned, secured, governed, and operated, covering cloud-native serverless ecosystems and containerized workloads, all delivered through infrastructure as code (IaC) that manages both cloud and on-premise environments.

Like every architect on the team, you will also contribute across all platform domains and may lead initiatives in any of them, so broad, enterprise-level platform thinking and engineering excellence are as essential as cloud depth.

What you will be doing

You will make a significant impact on the company’s modernization and transformation journey by designing, documenting, and driving adoption of modern engineering patterns for next-generation platform capabilities and the ways product teams consume them.

Public cloud adoption is central to that journey. Your focus spans the full cloud lifecycle, from landing zones, account structures and vending, network connectivity, and inherited IAM and network policies, through workload placement and migration, to cost management and ongoing operations.

Together these form the secure baseline that Platform Engineering and product engineering teams consume and build upon. You will draw on significant hands-on software engineering experience in product delivery to turn complex business needs into thoughtful, practical solutions.

You will bring cloud-native patterns to our platforms, build roadmaps that clearly sequence the steps of our modernization journey, and apply enterprise architecture practices such as governance, ecosystem analysis, and vendor evaluation, while providing thought leadership on what is possible as we transform engineering culture at FIS.

Specifically, you will be responsible for:

• Contributing platform thinking and subject matter expertise across all platform domains, applying modern engineering and architectural patterns to design systems (APIs, services, events, data, UI, and supporting capabilities) that enable engineering teams to deliver product capabilities rapidly
• Creating and communicating best-practice target-state designs that use cloud-native patterns and are easy for engineering teams to consume, supported by clear artifacts such as business case and process context, context and sequence diagrams, and architecture decision records
• Leading the architecture and roadmap for public cloud foundations, including landing zones and multi-account structures, automated account vending, hybrid and private network connectivity, identity federation and least-privilege IAM, encryption and key management, and guardrails delivered as policy as code that delivery teams inherit by default
• Defining the paved paths product teams use to build and run workloads in the cloud, including serverless and event-driven patterns, managed Kubernetes and container platforms, reusable IaC modules with GitOps-based delivery and drift detection, multi-zone and multi-region resilience, and FinOps practices such as tagging, cost visibility, and optimization
• Partnering with leaders across the Platform Engineering organization to introduce, socialize, and champion modernization of front-end, middle-tier, and back-end technology stacks within an AI-first delivery model
• Leading evaluations of new and existing vendors for fit with Platform Engineering’s strategy, technology approach, and integration patterns
• Defining and driving adoption of integration patterns across internal systems, services, and capabilities so that quality data, events, and services are available for consumption regardless of channel
• Partnering with platform owners, product partners, and other stakeholders on the intake and evaluation of platform capabilities and features, influencing design decisions and approaches before execution and delivery begin
• Validating designs through hands-on proofs of concept and reference implementations, and contributing to architecture reviews and governance across the team
• Articulating the business value of the architectural roadmap, including fact-based “over the horizon” perspectives with options and trade-offs that align to the broader business and engineering strategy

What you will need

• 10+ years of solution architecture and senior software engineering experience, including significant hands-on product delivery, in a fast-paced, global software delivery organization that operates with ambiguity
• Expert understanding of software and internet architecture, including modern front-end and back-end stacks, API management and identity and access management, cloud-native and on-premises infrastructure (containers, Kubernetes, infrastructure as code), networking and internet connectivity, and browser and mobile application delivery
• Deep expertise designing and delivering public cloud capabilities at enterprise scale on one or more major providers (AWS, Azure, or Google Cloud), including landing zone and account architecture, serverless and container platforms, cloud networking and hybrid connectivity, IaC and policy as code, and workload migration and modernization
• Strong understanding of how IAM, security, and network policies inherited by engineering teams affect the security, reliability, operability, and troubleshooting of their services, and how to design those policies so teams remain both safe and productive
• Demonstrated track record of delivering platform capabilities that power consumer-facing software products, especially API- and event-driven systems
• Deep experience adopting and operating within a modern SDLC and engineering practice (AI-enabled development, DevSecOps, CI/CD, GitOps, and platform-as-a-product)
• Thorough understanding of modern information security and data protection practices, including the cloud shared responsibility model, and how to apply them across technology stacks in regulated environments
• Collaborative, low-ego approach focused on business outcomes, with the ability to motivate and energize others and influence without authority to achieve common goals
• Exceptional communicator who can navigate and influence at every level of the organization, tailoring the message to any audience to achieve the desired outcome

Preferred qualifications

• Experience in financial services or other regulated industries, including operational resilience and third-party risk requirements (such as cloud concentration risk and exit planning) and how they shape architecture decisions
• Experience shaping multi-cloud or hybrid cloud strategy, including workload placement, portability trade-offs, and data residency
• Experience designing cloud infrastructure for AI workloads, such as GPU capacity planning, managed AI services, and secure access to models and data
• Professional-level cloud architecture certifications (for example, AWS Certified Solutions Architect – Professional, Microsoft Certified: Azure Solutions Architect Expert, or Google Cloud Professional Cloud Architect)
• Undergraduate degree in Engineering, Computer Science, or another technical field

Personal characteristics

• Demonstrates sound judgment and flexibility, thinking comprehensively about issues and developing solutions that account for the broader context and strategy
• Maintains a positive, adaptable approach to rapidly shifting priorities, topics, and environments
• Takes initiative, translating strategy into action and driving delivery with a “roll up the sleeves” approach
• Remains calm and structured under pressure, bringing clarity to high-stakes situations such as major incidents and critical decisions
• Builds strong relationships and negotiates effectively with internal and external stakeholders, grounding decisions in data
• Combines intellectual curiosity and a drive for excellence with a track record of success and a reputation as someone others enjoy working with
• Brings strong attention to detail, a commitment to adopting and implementing best practices, and a bias toward continuous improvement
• Embodies and delivers the firm’s values and culture towards colleagues, clients, and communities:
