Job Description: As a Platform Engineer in R&D, you'll join the Platform Team to design, build, and maintain the foundational infrastructure, tooling, and automation that product teams rely on to develop and deliver software efficiently. This is a hands-on role, if you enjoy making developers' lives easier through great tooling, automation, and rock-solid Kubernetes-based infrastructure, we'd love to hear from you. Please note this is a hybrid position, and would require 2 days per week in the Cambridge office.

What will I be doing:

• You will be responsible for running and evolving our Kubernetes platform across multiple environments, ensuring applications are deployed reliably at scale.
• Your deep experience with container orchestration and cloud-native tooling will be central to everything you do.
• You will support development teams in optimising their use of public cloud resources and assist with the transition of new applications to production.
• Collaborating with development teams to ensure infrastructure meets their requirements while promoting scalable, cloud-native application practices.
• Operating and improving Kubernetes clusters day-to-day, with a focus on reliability, observability, and performance.
• Building and maintaining CI/CD pipelines to accelerate software delivery.
• Driving infrastructure-as-code practices using tools like Terraform or CloudFormation.
• Staying current with the cloud-native ecosystem, introducing pragmatic solutions to the team, and addressing operational challenges through automation.
• Embedding security into platform design and coaching other teams on best practices.
• Designing solutions and services with security controls engineered to mitigate threats.
• Managing service components to ensure they meet business needs and key performance indicators.
• Liaising with other team members to coordinate changes across components.

What experience do I need:

• You should have strong Kubernetes experience, at least two years operating, troubleshooting, and scaling clusters in production environments.
• You should be comfortable with networking, storage, RBAC, and workload scheduling.
• Familiarity with infrastructure provisioning tools such as Terraform and CloudFormation, along with Infrastructure as Code methodologies, is important.
• A good understanding of networking and security principles is crucial, as is the ability to solve problems and analyse patterns in behaviour and logs.
• Experience with continuous integration systems such as GitHub Actions, GitLab CI, and Jenkins.
• Proficiency in working with source control systems.
• Strong communication and interpersonal skills, with fluency in English both in written and verbal forms.

Nice to have:

• Scripting or programming ability (Python, Bash, Go, or similar) — useful for building tooling and automation but not a prerequisite.
• Experience with observability stacks (Prometheus, Grafana, OpenTelemetry).
• Familiarity with service mesh, GitOps workflows, or platform-as-a-product thinking.

As a growing business strengthening its governance and controls, this role plays a part in supporting high standards of integrity and accountability.
