About the Company

Join a growth-stage technology company investing in the next phase of their engineering and platform capability. As they scale, they're building out a dedicated platform function to support secure, reliable, and developer-friendly delivery across the organisation.

Role Overview

This is an opportunity for a lead/principal-level Platform Engineer to help build a secure, reliable, developer-friendly platform function that enables engineering teams to deliver quickly and safely. You'll start as a hands-on senior technical contributor, laying the foundations for a future platform engineering capability, with the role expected to evolve as they scale.

This is a platform enablement role, not traditional ops support — focused on automation, operational maturity, resilience, and developer experience.

Key Responsibilities

• Design, build, and maintain scalable cloud infrastructure and platform tooling
• Improve reliability, observability, deployment automation, and CI/CD pipelines
• Build reusable platform capabilities (e.g. event streaming, storage/provisioning patterns, secrets management)
• Improve developer experience through self-service tooling, golden paths, and reduced operational friction
• Partner with security/engineering leadership to operationalise RBAC, access governance, and compliance requirements
• Support incident response, monitoring, and operational SLAs
• Mentor engineers and help shape long-term platform strategy and standards

Required Experience & Skills

• Strong background in platform engineering, DevOps, SRE, or cloud infrastructure
• Deep experience with AWS
• Strong infrastructure-as-code skills (Terraform, Pulumi, CloudFormation, etc.)
• Experience with CI/CD, Linux, containerisation, and Kubernetes
• Experience with distributed systems, event-driven architecture, or streaming platforms
• Working knowledge of RBAC, IAM, secrets management, and operational security practices, ideally in a regulated environment
• Strong automation/scripting ability and systems-thinking approach
• Comfortable operating in a scaling, growth-stage environment

Key Competencies

• Automation-first, ownership-driven mindset
• Strong communication and cross-team collaboration
• Calm under operational pressure
• Ability to simplify complexity and improve engineering flow

We are an equal opportunities employer and welcome applications from all suitably qualified persons regardless of their race, sex, disability, religion/belief, sexual orientation or age.
