What You'll Do:
OCC's Platform Architecture team is responsible for the infrastructure, cloud, networking, compute, storage, and observability tooling that critical market functions depend on. The Principal, Platform Architecture is a senior individual contributor who defines the technical direction for OCC's core platform capabilities - owning how we build, deploy, operate, and evolve the infrastructure layer across both legacy and cloud-native environments.
This is a hands-on architecture role with enterprise-wide impact. You will lead POC efforts, drive platform standards adoption, and serve as the senior technical voice on platform concerns across programs including the Renaissance/Ovation transformation. You will work closely with Application Architecture, Engineering, Security, and operations teams to ensure the platform is a resilient, scalable foundation - not a bottleneck.

Primary Duties and Responsibilities:

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

Define and Own Platform Architecture

• Lead architecture design and decision-making for OCC's core platform capabilities: container orchestration, streaming infrastructure, cloud architecture, CI/CD and
• GitOps pipelines, and observability
• Develop and maintain target-state platform architectures with clear transition plans from current state
• Own reference architectures for Kubernetes-based workloads, Kafka streaming topologies, Flink stream processing, and AWS infrastructure patterns
• Establish platform architecture standards and guardrails that application teams can build against reliably
• Ensure non-functional requirements - availability, latency, throughput, recoverability - are addressed at the platform level, not delegated to individual application teams

Drive Platform Modernization

• Architect and guide migration of workloads to cloud-native patterns on AWS, including compute, networking, storage, and security services
• Define OCC's GitOps model - infrastructure-as-code practices, pipeline standards, environment promotion, and configuration management at scale
• Evaluate and recommend platform technologies and tooling; lead proof-of-concept efforts to validate architectural decisions before commitment
• Identify and reduce platform risk across the portfolio - single points of failure, unsupported dependencies, capacity constraints, and operational gaps

Collaborate and Influence

• Partner with Application Architecture to ensure platform capabilities match application design requirements - particularly for high-throughput, low-latency clearing workloads
• Engage Engineering and operations teams to ensure platform designs are buildable, operable, and supportable - not just theoretically sound
• Facilitate architecture working sessions with technical leads and business stakeholders; communicate platform decisions clearly to both technical and non-technical audiences

Raise the Bar on Resilience and Operability

• Establish observability standards - logging, metrics, tracing, and alerting - as a platform-level capability, not an afterthought
• Define capacity planning and performance engineering practices for platform infrastructure
• Participate in incident reviews and post-mortems; translate operational findings into durable platform architecture improvements
• Ensure platform architecture satisfies OCC's regulatory obligations under Regulation SCI and CPMI-IOSCO resilience principles

Supervisory Responsibilities:

None

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.

Required

• 10+ years of experience in infrastructure, platform, or systems architecture roles with demonstrated ownership of enterprise-scale platform decisions
• Deep, hands-on expertise with Kubernetes - cluster architecture, workload design, networking, security, and operational patterns at scale
• Hands-on experience architecting Apache Kafka deployments - topic design, partitioning strategy, consumer group patterns, schema management, and operational concerns
• Practical experience with Apache Flink or equivalent stream processing frameworks - job design, state management, and deployment on Kubernetes
• Strong AWS architecture experience - VPCs, EC2, EKS,MSK, S3, IAM, KMS, networking, and security services
• Demonstrated experience designing and implementing GitOps pipelines - infrastructure-as-code, environment promotion, secrets management, and release automation using tools such as Flux, ArgoCD, Terraform, or Helm
• Experience with brownfield/legacy environments alongside cloud-native programs
• Ability to produce clear, comprehensive architecture artifacts: diagrams, ADRs, reference architectures, and transition plans
• Strong communication skills - able to present platform decisions to executive audiences and work through technical trade-offs with engineering teams

Preferred

• Experience in financial services, particularly regulated environments (SIFMU, clearinghouse, exchange, or bank)
• Familiarity with Regulation SCI, CPMI-IOSCO resilience requirements, or equivalent financial market infrastructure regulatory frameworks
• Experience with observability tooling at scale - OpenTelemetry, Prometheus, Grafana, Splunk, or equivalent
• Familiarity with high-performance and low-latency computing patterns relevant to risk and clearing workloads
• Experience with enterprise architecture frameworks such as TOGAF

Technical Skills

• Kubernetes (EKS or self-managed), Kafka, Apache Flink
