This is a hands-on technical leadership role for an engineer who thrives on solving complex distributed-systems problems, sets the technical bar for the team, and cares deeply about resiliency, latency, and operational excellence at high transaction volumes.

Responsibilities

• Design and develop core Traffic Platform components, including the API Gateway, MCP Gateway, AI Gateway, and Service Mesh.
• Lead the gathering of functional requirements, authoring of technical specifications, and project and test planning across initiatives.
• Present designs, architectural decisions, and their trade-offs to technical review forums and drive alignment with stakeholders.
• Manage priorities, deadlines, and deliverables across concurrent projects with minimal oversight.
• Define comprehensive test strategies, including both positive and negative cases, to validate correctness and resiliency of solutions.
• Perform code reviews (primarily Go, Python, and Java) and provide clear, actionable feedback that raises the quality of the codebase.
• Debug complex, distributed failures including tracing transactions that traverse multiple Kubernetes clusters before reaching the destination service.
• Demonstrate a strong operational excellence mindset, with attention to observability, reliability, and incident readiness.

• Practical knowledge of Istio - how it works, how to configure it, its core features, and how to author Envoy filters.
• Strong understanding of Envoy internals and configuration.
• Hands-on experience with AWS (or an equivalent cloud), including Route 53, IAM, Transit Gateway, NAT Gateway, and managed data stores such as ElastiCache and DynamoDB.
• Strong programming proficiency in Go-lang and Java.
