Principal Platform Architect - Kafka, Flint, Kubernetes, Observability

· Lead architecture design and decision-making for 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

· Architect and guide migration of workloads to cloud-native patterns on AWS, including compute, networking, storage, and security services

· Define GitOps model - infrastructure-as-code practices, pipeline standards, environment promotion, and configuration management at scale

· 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

· 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 company regulatory obligations under Regulation SCI and CPMI-IOSCO resilience principles

· BS degree in Computer Science, Information Systems, Mathematics, or a similar technical field, or equivalent practical experience.

· 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

· CI/CD pipelines: Jenkins, GitHub Actions, or equivalent

· Observability: OpenTelemetry, Prometheus, Grafana, Splunk, or equivalent

· Unix/Linux environments; container and image management (Docker, Nexus/Artifactory)
