  • Support the Crew Tech Lead by lifting engineering capability through technical leadership, coaching, and consistent engineering practices.
  • Partner with product, architecture, and engineering teams to improve resilience, delivery flow, and customer outcomes, with clear ownership for operating the services the squad builds.

Requirements

  • Highly technical engineering leader who combines deep expertise in distributed systems, data platforms, with expertise in modern software engineering and AI-enabled delivery.
  • Led full-cycle engineering in a “you build it, you run it” environment, with experience designing, building, deploying, and operating software at scale.
  • Deep technical expertise across distributed systems, data platforms, and streaming-first architecture, ideally including Apache Flink.
  • Built or modernized microservice-based platforms using Java, Spring Boot, AWS, Kubernetes (EKS), and well-designed REST APIs.
  • Comfortable contributing code while setting high standards for engineering practices, code quality, patterns, and architecture.
  • Practical experience applying AI or GenAI in product, engineering, or decisioning environments, with sound judgment around governance, safety, and business value.
  • Understand how to design and evolve service domains, reusable APIs, and data products in a structured, domain-led architecture.
