Senior Software Engineer — Data Layer Automations (Rust, Node & GraphQL)

Job Title: "Senior Software Engineer — Data Layer Automations (Rust, Node & GraphQL)
Location: Sunnyvale, CA
Duration: 6 months Hybrid role


Role Description:

• About the role We run a federated GraphQL data layer that composes many back-end services into a single, typed API powering large-scale, consumer-facing web experiences.
• At its center is a Rust-based federation router; around it sit dozens of subgraphs, many written in Node/TypeScript, owned by teams across the org.
• We're looking for a senior engineer who writes production code and builds the automation that carries it safely to production.
• You'll own the pipelines for the router and its plugins end to end — build, test, benchmark, schema checks, and progressive rollout — and you'll contribute directly to the Rust and Node code those pipelines ship.
• If you believe the path to production is itself a piece of software worth engineering well, this role is for you. What you'll do Engineer the router's path to production.
• Design, build, and own the CI/CD pipelines for our GraphQL router on Rio (our internal CI/CD platform) — from Rust compilation, cross-target builds, and container images through automated testing and progressive deployment.
• Make router builds fast and reproducible: Cargo workspace and dependency caching, incremental and parallel builds, artifact signing, versioning, and provenance.
• Build in quality gates that matter for a latency-critical service: unit and integration suites, performance benchmarks with regression detection, fuzzing, dependency and vulnerability scanning, and config validation.
• Automate canary and staged rollouts with health- and SLO-based promotion, fast rollback, and zero-downtime config and binary updates across environments. Build the router and its extensions.
• Write and maintain Rust code in the router — custom plugins, coprocessors, auth, caching, telemetry, and query-governance features — alongside the core router team.
• Build the Node/TypeScript tooling and services that surround it: coprocessors, CLIs, test harnesses, and internal developer tools. Keep the graph safe to change. Own schema delivery workflows: automated composition, breaking-change and operation checks against real traffic, schema registry integration, and gated publishing for every subgraph.
• Provide paved-path pipeline templates so partner teams can build, test, and ship Node subgraphs onto the graph with minimal friction and strong guardrails. Raise the bar on developer velocity.
• Measure and improve build times, pipeline reliability, flaky-test rates, and lead time to production.
• Partner with platform, infrastructure, and security teams on environment provisioning, secrets management, and compliance requirements.
• Minimum qualifications 6+ years of software engineering experience, including significant time building and operating production backend or platform systems. Hands-on experience designing and owning CI/CD pipelines for production services — on Rio (our internal CI/CD platform) or a comparable platform (GitHub Actions, Buildkite, Jenkins, GitLab CI, Tekton, Argo).
• Production experience writing Rust, and a working understanding of the Rust toolchain: Cargo workspaces, features, cross-compilation, and build performance. Strong Node.js / TypeScript skills for building services, tooling, and automation. Solid experience with GraphQL APIs — schema design, resolvers, and how schema changes affect clients.
• Experience with containers and orchestration (Docker, Kubernetes), plus deployment strategies such as canary, blue/green, and feature flags. Comfort owning services in production: observability, SLOs, and incident response.
