Your Impact

  • Full Lifecycle Development: Own the design, codification, testing, and delivery of Kubernetes-based microservices configurations (Deployments, Services, Ingress, ConfigMaps) using Kubernetes, Helm. Build reusable base configs with environment overlays and enable safe promotion across dev, staging, and production.
  • DevOps & Microservices: Drive operational perfection in a GitOps model using Argo CD. Implement progressive delivery (canary releases, validation gates), codify autoscaling and resiliency, and manage secure secrets via HashiCorp Vault and Kubernetes Secrets.
  • Embrace AI technology: Use AI-assisted tools to accelerate development, validation, and optimization of configuration-as-code, improving delivery speed and reducing deployment risk.
  • Adaptable & Problem-Solver: Address complex challenges across configuration, policy, observability, and data services. Apply a data-driven approach using Prometheus and Grafana to improve reliability and performance.
  • Ownership & Quality: Own end-to-end configuration quality, enforcing governance with Open Policy Agent. Ensure secure, compliant deployments and full reproducibility, including backup, restore, and disaster recovery.
  • Support & Growth: Advance a self-service platform using Backstage and Argo CD, enabling teams to deploy via declarative configs while promoting standard processes and continuous improvement.

Minimum Qualifications:

  • Analytical Degree or equivalent experience: Bachelor's or higher degree in an analytical subject (e.g. Computer Science, Electronic/Software Engineering).
  • Work experience: 8+ Years demonstrated experience in software development.
  • Coding Aptitude: Extensive architecture and programming experience and the willingness to learn new technologies quickly.
  • Strong Kubernetes + microservices experience
  • Experience with GitOps (CI/CD)

Preferred Qualifications:

Any of the following skills would be particularly advantageous, but we encourage applications without these:

  • Hands-on with Helm or Kustomize
  • Experience with GitOps (e.g., Argo CD)
  • Knowledge of secrets management (e.g., HashiCorp Vault)
  • Experience with observability (metrics/logs/tracing)
