PrincipalSoftwareEngineer

**Job Requisition ID #** 26WD97610 **Position overview** We are building a large-scale, API-first streaming platform on Apache Flink, Apache Kafka, and AWS. The platform powers near-real-time ingestion, processing, and delivery of data for many internal and product-facing use cases. Everything is exposed and governed behind well-designed APIs, and teams consume capabilities through a self-serve portal as well as programmatic interfaces. We are hiring a Principal Engineer to own architecture and technical design for this platform: from stream topology and operational model to control-plane services, developer experience, and production excellence. This is a high-impact role with real architectural ownership - you will partner across product, platform, and data teams, mentor engineers, and raise the bar on reliability, security, and velocity. **Responsibilities** * Architect and design the streaming platform * Define end-to-end architecture for stream processing: ingest, stateful processing, delivery, replay, and integration with downstream systems on Flink and Kafka * Design API-first boundaries (REST and event-driven patterns as appropriate) so streams, jobs, schemas, and operational workflows are manageable and safe at scale * Shape multi-tenant or multi-team patterns: quotas, isolation, naming, observability, and upgrade strategies for long-running Flink workloads * Evolve AWS-native deployment and operations (networking, IAM, scaling, resilience patterns) aligned with organizational security and compliance requirements * Build and evolve platform surfaces * Lead design of Spring Boot-based services that implement the platform control plane, metadata, orchestration hooks, and integration with Kafka/Flink operations * Contribute to the self-serve portal and related UX: work with product and design and apply solid frontend engineering practices so internal users can onboard, configure, and operate without excessive manual support * Drive developer experience: docume
