Responsibilities

We're looking for a Senior Staff Platform Engineer to set technical direction for our platform, not just build within it. This is the most senior IC role on the team: you'll own architecture for our most consequential, cross-org infrastructure initiatives, and be the person other senior and staff engineers look to when a design decision needs to hold up across every team that depends on it. Recent and current flagship work at this level includes leading the Istio service mesh rollout as single-threaded owner across the entire organization; shaping the architecture behind our Multi-Region Resilience Program; and owning the technical direction of our AI-enriched Service Catalog. You'll operate at the intersection of deep technical execution and org-wide influence, staying hands-on in critical code and infrastructure paths while setting the patterns other teams build on.
Own group-critical platform initiatives: Take single-threaded ownership of multi-quarter, cross-org programs — service mesh adoption across independent clusters and business units, multi-region resilience strategy, and foundational platform initiatives. Align systems and abstractions to long-term organizational strategy.
Set direction others build on: Define the architectural patterns, golden paths, and platform primitives (Istio mTLS/traffic policy, AI agent golden paths, MCP-backed service APIs) that other engineers implement against. Create shared components that improve delivery consistency across teams rather than one-off solutions per squad.
Lead through hands-on technical excellence: Stay deeply engaged in the hardest parts of the systems you own — debugging production incidents at the mesh layer, hardening migration tooling, resolving cross-team architectural conflicts — earning credibility through visible, high-quality technical work rather than through title alone.
Drive execution across organizational boundaries: Coordinate rollouts that depend on multiple engineering orgs contributing resources on a schedule (e.g., a named engineering champion per business unit for a service mesh migration). Anticipate systemic blockers — resourcing gaps, conflicting migration sequencing, environment drift between staging and production — and resolve them before they stall the program.
Own testing infrastructure strategy end-to-end: Serve as DRI for how engineering teams validate changes before production, spanning iteration environments, pre-prod confidence gates, and multi-service validation for cross-service changes.
Mentor Staff and Senior engineers: Coach engineers below you on system design, migration strategy, and how to navigate ambiguity in cross-team initiatives. Raise the technical bar of the org by example, not just by review.
Drive org-wide reduction of technical debt and cost: Lead large-scale infrastructure consolidations and migrations (CI/CD platform changes, artifact registry modernization, dependency upgrades) end-to-end, with the rollout discipline, cost modeling, and stakeholder communication that a multi-hundred-repo change demands.
Establish the metrics that prove platform investment works: Define and drive adoption of the leading indicators — adoption rate, incident trends, cost trajectory, developer sentiment — that let leadership see platform work as a business asset, not overhead.

Qualification

12+ years in PlatformDeepA track record of leading complexProficiency in at least one of Go

Required

12+ years in Platform, Infrastructure, DevOps, or SRE roles, including demonstrated ownership of at least one initiative that spanned multiple teams or business units, not just a single team's roadmap.
Deep, production-proven expertise in Kubernetes/EKS, service mesh (Istio strongly preferred — mTLS, traffic shaping, sidecar architecture, multi-cluster rollout), and Infrastructure-as-Code (Terraform or similar) at meaningful scale.
A track record of leading complex, multi-quarter technical programs from architecture through execution — including the ability to produce the kind of cost/risk analysis and phased proposal that secures leadership buy-in and funding.
Experience debugging and resolving production incidents in distributed, multi-hop systems (e.g., proxy/sidecar-layer failures, cross-service auth issues, environment-specific config drift between staging and production).
Proficiency in at least one of Go, Python, TypeScript, or Java, with the judgment to know when to write code yourself versus when to set direction and delegate.
A demonstrated ability to influence without direct authority — driving alignment across engineering orgs that don't report to you, and building the kind of technical credibility that makes other senior engineers want to build on your patterns rather than route around them.
Experience mentoring Staff-level engineers and shaping how a broader engineering org approaches system design, not just your immediate team.

Preferred

Experience with AI-native platform tooling: agentic tooling, MCP-backed APIs and golden paths for deploying AI agents in production.
A track record of driving large-scale cost or infrastructure consolidation initiatives (CI/CD platform migrations, cloud cost optimization, vendor consolidation) with measurable business impact.
Experience with multi-region or high-availability architecture, including RPO/RTO planning and per-journey SLO definition.
Comfortable authoring RFCs and leadership-facing technical proposals and presenting them directly to senior engineering leadership.
