What we're looking for

  • "Developer First" Mindset & Sensitivity to Developer Experience (DevEx):
  • Understands that their primary users are dozens of software engineers across internal squads. Listens, understands, discusses, and prioritizes developer needs within product and technical contexts.
  • Designs APIs, boilerplates, and platform solutions focused on reducing cognitive load, abstracting infrastructure complexity, and enabling team autonomy.
  • "Platform Engineering" Vision:
  • Investigates developer pain points across squads and delivers high-value self-service capabilities.
  • Automates platform processes and provides clear, comprehensive documentation.
  • Hands-On Approach & Pragmatism:
  • Delivers practical, value-driven engineering solutions. Enjoys solving real operational bottlenecks while avoiding unnecessary abstractions or over-engineering.
  • Communication & Autonomy:
  • Communicates architectural decisions effectively, leads internal technical workshops, and writes high-quality integration guides.
  • Proactively identifies bottlenecks in developer workflows and tools, implementing quick wins without requiring micromanagement.
  • Backend & Integration Ecosystem:
  • Node.js & TypeScript (Portal Extension): Proficiency in Node.js and TypeScript tailored specifically for governing, building, and extending our Developer Portal (Backstage backend plugins, custom integrations, catalog processors, and Scaffolder actions).
  • .NET Ecosystem: Strong experience developing robust, scalable services using.NET Core / C#.
  • API Design & Resilience: REST API design and consumption using resilience patterns (circuit breakers, retries, rate limiting) with libraries like Polly.
  • Workflow & Event Orchestration: Experience with event-driven architecture, webhooks, or workflow engines (e.g., Temporal, Argo Workflows, KEDA) to handle long-running, asynchronous infrastructure tasks and reliably interact with external APIs.
  • Frontend Ecosystem:
  • Core Frameworks: Advanced knowledge of React and TypeScript for building modular, high-performance portal interfaces and custom Backstage UI plugins.
  • UX for Developers: Ability to translate complex infrastructure workflows into intuitive, low-friction user interfaces for engineering teams.
  • Containers & Orchestration:
  • Docker: Hands-on experience with container management, image optimization (multi-stage builds), and container security.
  • Kubernetes (K8s): Experience deploying, managing, and orchestrating applications in Kubernetes clusters (deployments, services, ingresses, configmaps).
  • CI/CD & GitOps:
  • CI Pipelines: Building and managing Continuous Integration pipelines for automated builds, testing (unit/integration), static code analysis, and container registry management (Harbor).
  • GitOps & Delivery: Practical experience with GitOps workflows and Continuous Delivery, preferably using ArgoCD.

Nice to have

  • Nice-to-Have:
  • Platform Engineering, IDPs & Control Planes:
  • Internal Developer Platforms & Control Planes: Experience with tools like Crossplane, Humanitec, Kratix, or custom Kubernetes Operators/CRDs for infrastructure provisioning and abstraction.
  • Backstage Ecosystem: Advanced experience building custom Backstage templates and integrating complex software catalog structures.
  • Configuration Management: Familiarity with Helm, Kustomize, or declarative configuration tools for managing application environments.
  • Cloud Computing & Infrastructure as Code (IaC):
  • Cloud Platforms (GCP/Multicloud): Knowledge and practical experience with Google Cloud Platform (GKE, Cloud Run, IAM, Secret Manager) or cross-cloud migration projects (Azure to GCP).
  • Terraform / OpenTofu: Experience provisioning and automating cloud infrastructure using IaC.
  • Observability & Telemetry: Familiarity with OpenTelemetry standards and building/querying observability dashboards using the Grafana Stack (Prometheus, Loki, Tempo).
  • AI-Assisted Development: Interest or experience leveraging AI-assisted development tools (Gemini, Copilot, Cursor) to automate platform and workflow tasks.
