Platform Engineer

Waystone is a leading provider of institutional governance, administration, risk and compliance services to the asset management industry. With over 25 years’ experience, we support many of the world’s largest asset managers, providing a comprehensive range of specialist services from a global network of offices.

The Platform Engineering team builds and operates Waystone’s engineering platform, spanning cloud infrastructure, CI/CD, observability, on-call and our internal developer portal. We provide the secure, automated foundations that the firm’s regulated services run on. We are looking for a Platform Engineer to help scale this platform through standardised, automated and compliant patterns, accelerating delivery for our development delivery teams while raising operational resilience across the estate.

We are a cross-skilled team by design: rather than narrow specialisation, we want every engineer able to work across the platform, giving us broader coverage, resilience and shared ownership.

• Take ownership of larger, moderately complex pieces of platform work, setting objectives and delivering against project goals with a direct impact on team results.
• Design, implement and maintain scalable cloud infrastructure patterns and reusable Terraform modules across Azure, AWS and OCI, with a primary focus on Azure.
• Develop and maintain Infrastructure as Code (IaC) libraries to ensure consistent, compliant and repeatable environments across all cloud providers.
• Build and support CI/CD and deployment automation using Git Hub Actions, Octopus Deploy and ArgoCD, and configuration management using Ansible and Octopus Deploy.
• Support and enable development delivery teams – provisioning autonomous environments and reducing deployment friction while maintaining guardrails and separation of duties.
• Provide operational support for containerised and micro-service workloads on Azure Kubernetes Service (AKS), maintaining high availability and reliability.
• Manage core infrastructure lifecycle tasks – vulnerability remediation and patching, upgrades, scaling and decommissioning across the Windows and Linux estate.
• Drive the adoption of cloud governance policies, security standards and architectural best practice, and help maintain continuous compliance evidence against the firm’s obligations (SOC 2, ISO 27001, GDPR, DORA).
• Contribute to observability and monitoring across the estate, and to incident response and on-call, including troubleshooting and root cause analysis that drives systemic improvement.
• Support disaster recovery testing to validate recovery plans and ensure rapid, reliable restoration of services.
• Identify and recommend improvements to systems, processes and infrastructure patterns to improve operational resilience, performance and cost efficiency.
• Explain and advocate technical approaches to development delivery teams and colleagues across IT, influencing platform practices and standards at an operational level.
• Provide guidance, code review and support to junior engineers, helping them develop across the platform.
• Document infrastructure blueprints, standards and standard operating procedures in Confluence and our internal Platform Portal to enable self‑service.
• Participate in the on‑call rota to support critical infrastructure services.

• University degree or equivalent practical experience, with a minimum of three years’ experience as a Platform Engineer, Cloud Infrastructure Engineer, Dev Ops Engineer or similar role.
• Strong experience designing and implementing infrastructure in Azure and AWS.
• Deep, hands‑on expertise with Infrastructure as Code using Terraform.
• Experience building and debugging CI/CD and deployment pipelines (e.g. Git Hub…
