Your Future Role within QRT
You will help automate all aspects of a growing, cutting-edge datacentre and research platform. You will build tooling, pipelines, and guardrails that turn network intent into safe, repeatable outcomes for QRT's high-performance on-premise datacentre.

  • Design and evolve the network automation framework (source of truth, templating, validation, change control).
  • Build idempotent automation to provision and operate data centre fabrics at scale.
  • Integrate with vendor APIs and SDKs (e.g. Arista EOS, NetQ etc.)
  • Capture network intent as code, ensuring peer reviews and quality gates.
  • Instrument the network with telemetry, alerting, and SLOs to drive automated remediation.
  • Adhere to NetDevOps practices and share knowledge across the team.
  • Collaborate with network and platform engineers to translate designs into automated workflows.
  • Deliver frequent, incremental improvements through safe, tested changes.
  • Monitor vendor and industry developments and propose practical adoption paths.

Your Present Skillset

  • Advanced Python development for production-grade tools and services.
  • Go (preferred) for performant tooling.
  • Strong Ansible experience (roles, collections, YAML/JSON data models).
  • Git proficiency including branching, pull requests, and semantic versioning.
  • Observability fundamentals (Prometheus, Grafana, logging and tracing).
  • Source of truth/CMDB systems (NetBox, Nautobot etc.).
  • Linux networking (iptables, DHCP, DNS) and strong Bash scripting.
  • Workflow orchestration (Temporal or equivalent).
  • Network validation and testing tools (pyATS, NAPALM etc.).
  • Containers and orchestration (Docker, Kubernetes).
  • Secure secrets and configuration management (Vault, PKI best practices).
  • Experience with data centre fabrics, QoS, and high-performance networking is a plus.

In addition to professional achievement, we are offering initiatives and programs to enable employees achieve a healthy work-life balance.
