Job summary

Intuit is seeking a Staff Software Engineer to design and build core traffic infrastructure that powers our platform at scale, including API Gateway, MCP Gateway, AI Gateway, and Service Mesh.

This hands-on technical leadership role requires solving distributed-systems challenges, setting technical standards, and ensuring resiliency and low latency across high-volume transactions. You will actively contribute production code in Go, Python, and Java.

Qualifications

• 10+ years of experience designing and developing platform software backend services, distributed systems, and cloud infrastructure operating at scale on Kubernetes with Istio/Envoy.
• Hands-on experience with AI-assisted development tools such as Claude or Cursor or equivalent.
• Deep understanding of Kubernetes fundamentals, including the control plane, clustering, Deployments, StatefulSets, and DaemonSets.
• Solid understanding of how Kubernetes controllers operate.
• Strong grasp of networking concepts and protocols, including TCP, TLS, HTTP/1.1, HTTP/2, and gRPC.

• 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.

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.
• Remain hands-on: contribute production-quality code and continuously improve existing solutions.
