Ocean Infinity is seeking a Senior Platform Engineer to design, build, and evolve the core platform systems that underpin our software delivery and operational reliability. This role sits within our Software organisation and focuses on strengthening the cloud, Kubernetes, CI/CD, and internal tooling foundations that enable teams to deploy, operate, and troubleshoot services with confidence.

You will take ownership of key platform components, improve developer self-service capabilities, and enhance observability, resilience, and operational efficiency across a complex, distributed technology landscape.

What will you do:

  • Design, build, and evolve core platform systems supporting cloud infrastructure, Kubernetes, CI/CD pipelines, and internal tooling.
  • Contribute to platform architecture and implementation strategies that support scalable, reliable operations across the organisation.
  • Own and deliver high-impact platform improvements across infrastructure, deployments, and automation.
  • Develop secure, fault-tolerant, and efficient platform capabilities that are easy for product teams to adopt.
  • Improve developer productivity by creating internal tools, services, and workflows that reduce friction across build, test, and deployment processes.
  • Strengthen observability by improving monitoring, logging, alerting, and operational visibility across environments.
  • Investigate and resolve complex issues across distributed systems, cloud services, networking, and Kubernetes, translating findings into measurable improvements.
  • Collaborate closely with engineering and product teams to support new features, resolve integration issues, and ensure services run reliably on the platform.
  • Evaluate and introduce new cloud-native and DevOps technologies that improve delivery speed, reliability, and developer experience.
  • Promote and reinforce platform standards, patterns, and best practices that enable secure, scalable, and well-operated services.

Who you are:

You are a hands-on, pragmatic platform engineer who enjoys owning complex systems and making them simpler, more reliable, and easier to use. You are comfortable operating in production environments, troubleshooting distributed systems, and working closely with delivery teams to remove friction. You balance technical depth with a strong sense of responsibility for reliability, security, and developer experience.

Qualifications and skills:

Essential:

  • Degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
  • 5+ years’ experience in Platform Engineering, SRE, DevOps, or infrastructure-focused software engineering roles.
  • Strong experience with cloud platforms (Azure preferred), including networking, identity, compute, and storage fundamentals.
  • Deep, hands-on experience operating Kubernetes in production environments.
  • Experience running and supporting containerised services at scale.
  • Strong use of infrastructure-as-code to automate environments and operational workflows.
  • Experience building, owning, and maintaining CI/CD pipelines, internal tooling, or delivery automation.
  • Proven ability to troubleshoot complex issues across distributed systems, containers, networking, and cloud services.
  • Solid understanding of monitoring, logging, alerting, and observability principles.
  • Ability to develop scripts or tools in languages such as C#, Python, or Go to support platform operations and automation.
  • Strong autonomy, time management, and ability to operate effectively in fast-moving environments.
  • Clear communicator who collaborates well across teams.
  • Fluent written and spoken English.

Desirable:

  • Experience with infrastructure-as-code tooling such as Terraform and modern Kubernetes configuration approaches (e.g. operators, GitOps).
  • Strong understanding of Kubernetes internals, cluster lifecycle management, and multi-cluster architectures.
  • Experience operating platforms across both cloud and on-prem environments, including Windows and Linux systems.
  • Understanding of distributed system design, service networking, messaging patterns, and event-driven architectures.
  • Familiarity with software architecture concepts such as CQRS and domain-driven design.
  • Good grasp of structured observability concepts across metrics, traces, and logs.

Salary: The salary varies for this position as we are recruiting in multiple regional locations and job grades. The salary process is based on skills, abilities, and experience required.

What you can expect:

At Ocean Infinity, we believe in creating equal opportunities for all, celebrating each and everyone’s differences.
