Senior Platform Engineer

• We’re looking for a Senior Platform Engineer to join our engineering team and champion the deployment architecture that drives our platform maturity
• You’ll be embedded within our engineering teams, optimizing day-to-day delivery across our on-premise estate while acting as the key engineering stakeholder to help shape, configure, and roll out our new Kubernetes platform, modernising how we deploy and scale workloads
• This is a hands-on role with real impact. You won’t be rubber-stamping tickets; you’ll have true autonomy over our CI/CD pipelines, automated guardrails, and migration strategies, shaping how engineering safely and rapidly ships value to production
• Utilise and contribute to Ansible-based deployment automation to facilitate seamless product feature releases, adhering to established TechOps peer-review processes
• Monitor application-level health within the cluster, collaborating with TechOps on incident response and driving post-mortems for engineering-led deployments
• Maintain clear documentation, deployment runbooks, and developer self-service guides to streamline the engineering onboarding and release processes
• Represent Engineering as a key stakeholder in platform design: Collaborate with TechOps to shape engineering self-service workflows, guardrails, and standards. This includes contributing requirements for Kubernetes primitives (such as Gateway API, RBAC, admission controllers, and resource policies) to ensure engineering teams can move fast safely, without compromising core platform stability
• Standardise application-level configurations: Work alongside TechOps to establish clear engineering standards within the namespaces for ingress, RBAC, namespacing strategy, and secrets management
• Drive phased application migrations: Partner with engineering teams to containerise and migrate existing workloads to Kubernetes, starting with non-critical environments to establish confidence before moving business-critical systems
• Build robust deployment pipelines: Establish CI/CD workflows for Kubernetes-based deployments (using Helm, Kustomize, ArgoCD, or similar) with automated guardrails to ensure fast, repeatable, and safe code delivery
• Implement application observability: Set up application-level metrics, logging, and alerting within the namespaces, ensuring engineering teams have the visibility they need to monitor workload health
• Create developer self-service documentation: Document deployment runbooks, manifest templates, and best practices so that engineers can onboard and self-serve safely within the established guardrails

Benefits

• Generous wellness benefits and paid time off
• Robust parental leave
• Competitive retirement savings benefits
• Employee learning & development opportunities

A methodical, security-conscious approachExperience with GitOps tooling: ArgoCD or FluxAbility to think creatively within constraints and plan pragmatically around them: our stack is real-world, not greenfield-perfect, and we need someone who can deliver iteratively, working with what exists today while roadmapping towards the ideal stateExperience with observability tooling (Prometheus, Grafana, Loki, Alertmanager or equivalent)Understanding of networking fundamentalsStrong scripting ability: Bash and PythonStrong interpersonal and communication skills: we’re a people-first culture where teamwork is paramount. On highly technical projects with many moving parts, the ability to collaborate openly, communicate clearly, and bring people with you is just as important as technical abilityStrong, demonstrable experience with Ansible: roles, inventories, vault, idempotency, the lotComfortable with Docker and Docker Compose in production environmentsFamiliarity with Helm chart authoring and managementExperience with infrastructure-as-code tools such as Terraform (even in an on-prem context)Prior experience in a role where you balanced greenfield work alongside BAU responsibilitiesExperience with secrets management tooling (HashiCorp Vault, Sealed Secrets, External Secrets Operator)Autonomously drive outcomes: we’re looking for people who demonstrate intent and take initiative, not those who wait to be told what to do nextYou have opinions about how things should be done, but you’re pragmatic; you know when to pick the right tool vs. the perfect toolYou write things down. Runbooks and diagrams: you treat documentation as part of the job, not an afterthoughtYou’re comfortable being the person engineering teams come to when something’s on fire, and you’re also comfortable saying \"let me schedule that properly\" when it isn’tYou can hold your own in a conversation with a software engineer, a network engineer, and senior leadership even if they all want different thingsWe welcome applications from candidates who don’t tick every box. If you’ve got strong Ansible and Kubernetes experience and the right mindset, we’d love to hear from you
