You’ll be part of a collaborative environment where you’ll play a key role in both day-to-day operations and longer-term projects, working across infrastructure, automation, and containerised environments.



Responsibilities

  • Use Helm charts to drive consistency and reliability in deployments.

  • Work with Rancher for cluster management and configuration.

  • Configure Ingress and networking for secure, reliable public access to services.

  • Collaborate directly with customers and internal stakeholders, ensuring technical requirements are met and solutions are well-documented.

  • Produce high-quality technical documentation and share knowledge across the team.

  • Support automation and CI/CD practices to improve efficiency.



Skills & Experience



  • Strong commercial experience with Linux administration (5+ years).

  • Proficiency with Helm charts for deployments.

  • Solid understanding of networking concepts (DHCP, subnetting, routing, firewalls).

  • Good documentation and communication skills, with customer-facing experience.

  • Comfortable troubleshooting and problem-solving in complex environments.

  • Exposure to Rancher and/or Istio Service Mesh is highly desirable.



Why Join?



  • Opportunity to take ownership of modern, containerised environments.

  • Work closely with customers as well as internal teams, delivering tangible business impact.

  • A collaborative culture that values innovation and professional growth.



If you’re a System Administrator with strong Kubernetes, Helm, and Linux expertise, and you’re excited about working directly with customers in a fast-paced environment, we’d love to hear from you.



We’re on a mission to put people and the planet before profit, leaving the world in a better place than we found it.
