We're hiring a Senior GraphQL Engineer (GraphQL Federation) to design, build and scale high-performance GraphQL APIs in a modern TypeScript/Node.js stack, deployed to Kubernetes in a cloud-native environment. This is an ideal contract for a GraphQL specialist who loves clean schemas, resilient services, and production-grade delivery.

The Role (Key Responsibilities)

  • Own end-to-end GraphQL API delivery: schema design through to production integration, focusing on performance, maintainability, security, and scalability.

  • GraphQL Federation expertise: design and implement supergraphs, subgraphs, resolvers, and governance patterns (versioning, evolution, backward compatibility).

  • Build and maintain TypeScript + Node.js Back End services, integrating with modern frontends and varied data sources.

  • Apply DevOps best practices: CI/CD pipelines (Jenkins, Concourse), Docker, Helm, Kubernetes, and YAML-based deployments.

  • Work in an Agile engineering environment: collaborate closely, review PRs, influence architecture, and continuously improve delivery.

  • Ensure APIs are observable and reliable in production using modern telemetry and APM tooling.

  • Champion GraphQL best practices and share knowledge across teams (mentoring/coaching desirable).

Required Experience (Skills & Tech)

  • Strong commercial experience delivering Federated GraphQL in production (schema-first design, supergraph/subgraph architecture, resolvers, schema governance, and API evolution).

  • Advanced TypeScript and Node.js Back End development.

  • Testing experience with modern frameworks such as Vitest and Playwright (API + end-to-end).

  • Hands-on delivery with Kubernetes, Helm, Docker, and YAML (cloud-native deployments).

  • Observability/telemetry: Prometheus, Grafana, OpenTelemetry, Datadog, APM tools.

  • Good understanding of CI/CD, infrastructure-as-code concepts, and production support best practices.

  • Ability to improve existing codebases and influence architectural direction.

  • Experience mentoring/coaching engineers is a plus.
