Job summary

Intuit is seeking a Staff Engineer to lead the Traffic platform, owning API Gateway, Service Mesh, and MCP Gateway efforts. You will guide architecture and security for high-stakes traffic between internal services and customer-facing products.

You will mentor senior engineers, drive migrations, and shape resiliency practices while partnering across the org to deliver a multi-quarter platform roadmap that enables AI agent interactions at scale.

Qualifications

• 8+ years of software engineering experience in large-scale distributed systems.
• Expertise with Envoy and Istio or modern service mesh architectures.
• Strong systems-level programming in Go and/or Java.
• Experience designing authentication systems for high-throughput traffic.
• Incident response and root cause analysis experience.
• Experience with AWS networking at scale.

Responsibilities

• Set architecture and engineering direction for API Gateway, Service Mesh, and MCP Gateway.
• Design and harden MCP Gateway, including auth flows for AI clients.
• Lead AI-agent-enabled traffic operations and service onboarding.
• Own major migrations end-to-end with backward compatibility focus.
• Apply resiliency practices to reduce P1/P2 incidents.
• Act as escalation point during high-severity incidents.
• Partner with cross-functional engineers to align technical strategy.
• Mentor engineers and participate in design reviews.
• Contribute to FY roadmap with scoping and risk assessment.

Job description

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 durable fixes (not just mitigation).
• Partner cross-functionally with adjacent Principal Engineers and engineering managers across Gateway, Mesh, MCP/3X, and Resiliency to align technical strategy across the org.
• Mentor senior and staff-track engineers, and raise the technical bar across the team through design reviews, and hands-on pairing on the hardest problems.
• Contribute to FY roadmap planning, providing grounded technical input on scope, sequencing, and risk trade-offs (e.g., what is realistic to land in a given quarter given platform constraints).

Qualifications

• 8+ years of software engineering experience, including significant time operating large-scale, low-latency distributed systems in production.
• Deep hands-on expertise with Envoy and/or Istio, or equivalent experience with modern service mesh and API gateway architectures (xDS APIs, sidecar/ambient models, traffic routing and policy enforcement).
• Strong systems-level programming ability in Go and/or Java, with experience migrating or operating hybrid-language platforms at scale.
• Demonstrated experience designing authentication/authorization systems for high-throughput, security-sensitive traffic — bonus for experience with agent-to-service or machine-to-machine auth patterns (OAuth, mTLS, token exchange).
• Track record of leading incident response and root-cause analysis for P1-level production issues on infrastructure with broad organizational impact.
• Experience with AWS networking and infrastructure (VPC, NAT/TGW, load balancing) and cost/performance trade-offs at scale.
• Proven ability to operate as a technical leader without direct reports — influencing through design docs, architecture reviews, and cross-team alignment rather than authority.

Preferred

• Direct experience building or operating infrastructure for AI agent traffic — MCP (Model Context Protocol), LLM gateway patterns, or similar emerging agent-to-service protocols.
• Experience with eBPF-based traffic capture or observability tooling.
• Familiarity with WASM or Go-based Envoy extension development.
• Background in FMEA methodology, chaos engineering, or Game Day-style resiliency practices.
• Experience operating within a platform team whose systems sit on the critical path for many downstream teams, with the discipline that entails (rigorous rollout gating, backward compatibility, staged enforcement).
