  • Strong API design skills: REST, OpenAPI, webhooks, pagination, versioning, and error contracts.

  • Production experience with event-driven architecture, including retries, poison messages, out-of-order delivery, and feedback loops. 

  • Strong GCP experience, including GKE or Kubernetes, serverless compute, managed messaging, managed databases, IAM, and Terraform. 

  • Experience leading customer-facing technical conversations with partner engineering teams. 

  • Ability to manage technical kickoff, API negotiation, go-live support, and live incident de-escalation. 

  • Practical AI-native engineering workflow experience, including AI-supported code production, review, testing, delivery, and validation. 

  • Strong written and verbal communication skills in English.

Nice to Have: 

  • Experience in logistics, last-mile delivery, autonomous vehicles, or robotics 

  • Experience with telephony, identity, or compliance-sensitive third-party integrations
