Head of Infrastructure Architecture

What You'll Do:

The Executive Director, Platform Architecture leads Platform Architecture team, owning the technical strategy and standards for all infrastructure domains cloud, on-premises, networking, compute, storage, and observability. This is a people leadership role responsible for developing a team of principal architects and ensuring their work produces coherent, enterprise-wide platform standards rather than isolated domain expertise.

The Executive Director, Platform Architecture translates resilience objectives and regulatory obligations into actionable platform architecture strategy, drives adoption of that strategy across Engineering and Operations, and ensures the platform layer keeps pace with technology transformation including the Renaissance/Ovation program and ongoing cloud adoption.

Primary Duties and Responsibilities:

To perform this job successfully, an individual must be able to perform each primary duty satisfactorily.

Lead the Platform Architecture Team

Lead, develop, and set direction for a team of principal architects covering cloud, on-premises infrastructure, networking, compute, storage, and observability domains

Own the Platform Architecture vision: deliver the resilient, scalable foundation upon which critical market functions depend making resilience the default, not the exception

Ensure individual architect domain expertise is synthesized into coherent, enterprise-wide platform standards not siloed recommendations

Manage team priorities, capacity, and delivery against architecture commitments across programs and initiatives Develop team members through coaching, feedback, and exposure to enterprise-scale architectural challenges

Define and Govern Platform Architecture Standards

Establish and maintain authoritative platform architecture standards spanning cloud (AWS), on-premises data center, hybrid connectivity, networking, compute, storage, and container platforms

Define reference architectures and infrastructure patterns that Engineering and application teams can consume without requiring per-project architecture engagement Own non-functional requirements standards at the platform level availability, fault tolerance, disaster recovery, latency, throughput, and capacity as first-class concerns applicable across all tiers of client's system portfolio

Enforce platform standards through Architecture Review Board participation and design review processes

Maintain infrastructure architecture documentation, ADRs, and transition plans that accurately reflect current and target state

Drive Infrastructure Modernization and Cloud Strategy

Own client's infrastructure architecture strategy for cloud adoption defining what moves to AWS, what remains on-premises, and how hybrid connectivity is structured

Ensure cloud architecture patterns for networking, security, identity, and compute are consistent, compliant, and operationally sound across all workloads Drive GitOps and infrastructure-as-code adoption pipeline standards, environment promotion, configuration management, and secrets management at enterprise scale

Lead architecture direction for container platform (Kubernetes/EKS), streaming infrastructure (Kafka), and stream processing (Flink) as foundational platform capabilities

Identify and systematically reduce infrastructure risk single points of failure, end-of-life dependencies, capacity constraints, and gaps in recovery capabilities

Partner Across the Organization

Serve as the primary platform architecture partner to Application Architecture, ensuring application designs are grounded in platform reality and platform capabilities evolve to meet application needs

Collaborate with Engineering, Security, and Operations to ensure platform architecture decisions are implementable, operable, and aligned to security requirements

Engage with Technology Leads, program management, and senior leadership to represent platform architecture in strategic planning, budgeting, and vendor decisions

Coordinate with Governance/Risk and Compliance to ensure platform architecture satisfies client's regulatory obligations under Regulation SCI and CPMI-IOSCO resilience principles

Ensure Operational Resilience

Establish observability standards metrics, logging, distributed tracing, and alerting as platform-level capabilities delivered to all application teams

Define and govern disaster recovery, business continuity, and resilience architecture across infrastructure domains

Drive capacity planning and performance engineering practices; ensure the platform is sized and architected ahead of demand, not reactive to it

Lead platform architecture participation in incident postmortems; ensure operational findings drive durable infrastructure improvements

Supervisory Responsibilities

Manages a team of principal architects and senior individual contributors across infrastructure architecture domains

Qualifications:

The requirements listed are representative of the knowledge, skill, and/or ability required. Reasonable accommodations may be made to enable individuals with disabilities to perform the primary functions.

Experience with Apache Kafka as enterprise streaming infrastructure deployment, operations, and topology design

Demonstrated experience leading GitOps and infrastructure-as-code programs Terraform, Helm, ArgoCD, Flux, or equivalent

Experience with hybrid and on-premises/cloud connectivity architecture network design, routing,firewalling, and security zoning

Ability to lead through influence and authority building alignment across Engineering, Security, Operations, and Governance

Strong communication skills able to represent infrastructure strategy to executive leadership and translate architecture decisions into actionable standards for engineering teams

Preferred

Experience in financial services, particularly regulated environments (SIFMU, clearinghouse, exchange, or bank)
