Staff Software Engineer - Traffic

Intuit is the global financial technology platform that powers prosperity for the people and communities we serve. With approximately 100 million customers worldwide using products such as TurboTax, Credit Karma, QuickBooks, and Mailchimp, we believe that everyone should have the opportunity to prosper. We never stop working to find new, innovative ways to make that possible.

Job Overview Intuit's Traffic Team sits at the center of every request that moves through Intuit's digital ecosystem. The team owns a custom-built API Gateway that handles all North-South traffic across Intuit's products, and a Service Mesh that governs East-West traffic between internal services. As a central platform team, the reliability, security, and performance of this team's systems have a direct and immediate blast radius across every consumer-facing and internal Intuit service — an outage or regression here does not stay contained to one product, it cascades. We are hiring a Staff Engineer to provide technical leadership across this platform, with particular focus on two of the team's highest-leverage, fastest-moving initiatives: the MCP Gateway (the transitional and target-state authentication and routing layer that lets AI agents such as Claude securely interact with Intuit services) and the broader shift toward AI-agent-driven traffic operations — including agent-assisted troubleshooting, config impact analysis, and automated service onboarding. This role requires someone equally comfortable operating at the depth of Envoy/Istio internals and at the altitude of a multi-quarter platform roadmap. Responsibilities Serve as a senior technical leader for the Traffic platform, setting architecture and engineering direction across API Gateway, Service Mesh, and MCP Gateway with a systems-wide view of how they interact. Drive the technical design and hardening of the MCP Gateway, including authentication flows for AI agent clients, performance and security readiness, and the path from transitional to target-state architecture. Lead or heavily influence AI-agent-enabled traffic operations work — agent-driven troubleshooting, automated config impact analysis, and service onboarding — as part of the team's recurring delivery cadence. Own or co-own major migrations (e.g., Envoy adoption, Java-to-Go transitions, ICGW/3X consolidation) end-to-end, from design through rollout, with explicit attention to backward compatibility and blast-radius containment given the platform's central role. Apply and evolve resiliency practices — FMEA, Game Day exercises, load shedding — to reduce the frequency and severity of P1/P2 incidents on shared infrastructure. Act as a technical escalation point during high-severity incidents affecting gateway or mesh traffic, driving root-cause analysis and
