Role Overview
We are looking for an experienced Platform Engineer to join a security-focused engineering programme, with responsibility for delivering automation across the full enterprise certificate lifecycle.
You will play a hands-on role in implementing and improving processes for certificate issuance, renewal, rotation, revocation and governance across cloud, infrastructure and application environments.
This is a delivery-focused position rather than a solution architecture role. You will be expected to work directly with platforms, infrastructure and application teams to implement robust, scalable automation within a fast-moving and security-critical environment.
Key Responsibilities
- Develop and implement automated certificate rotation processes across cloud, infrastructure and application environments.
- Automate certificate renewal workflows and support the implementation of certificate revocation processes.
- Integrate certificate lifecycle management capabilities with cloud platforms, services and enterprise applications.
- Make application-level code changes where necessary to enable or improve certificate automation.
- Manage and automate certificate operations using native AWS and GCP certificate management services.
- Build reusable and scalable infrastructure automation using Terraform and Ansible.
- Support certificate management across public and private cloud environments and enterprise platforms.
- Work closely with engineering and security teams to improve the reliability, consistency and security of certificate operations.
- Create and maintain operational runbooks, technical documentation and reusable automation components.
- Troubleshoot certificate-related issues and contribute to the continuous improvement of lifecycle management processes.
Essential Experience & Technical Skills
- 5+ years' commercial experience in hands-on platform, infrastructure or cloud engineering roles.
- Strong practical knowledge of Certificate Lifecycle Management (CLM) and Public Key Infrastructure (PKI).
- Proven experience working with AWS and/or GCP, including their native certificate management capabilities.
- Strong hands-on experience with Kubernetes and Linux.
- Extensive experience using Terraform and Ansible to automate infrastructure and operational processes.
- Strong Python development and scripting capabilities.
- Experience implementing security-focused infrastructure and platform automation.
- Demonstrable ability to take requirements through to hands-on implementation and production delivery.
- Comfortable working in environments where security, reliability and operational resilience are critical.
