Platform Engineering & Delivery

• Lead the design, development, and evolution of LOCP platform capabilities across development, test, and production environments.
• Build, enhance, and maintain platform services using Infrastructure as Code, automation, and engineering best practices.
• Contribute to platform architecture decisions and technology roadmaps, ensuring solutions align with strategic objectives and engineering standards.

Reliability & Operational Excellence

• Champion Site Reliability Engineering (SRE) principles across the platform, driving improvements in reliability, availability, resilience, and scalability.
• Implement and improve service observability through metrics, logging, tracing, dashboards, alerting, and operational tooling.
• Support incident analysis, root cause investigations, and continuous improvement activities to reduce operational risk and improve service quality.

Technical Leadership & Collaboration

• Act as a technical leader within the team, providing guidance, mentorship, and support to engineers across the platform organisation.
• Partner with architecture, product, security, infrastructure, and application teams to deliver platform capabilities aligned with business needs.
• Promote a culture of engineering excellence, collaboration, continuous learning, and innovation.

Ways of Working

• Operate effectively within agile and iterative delivery models.
• Manage multiple priorities in a dynamic and evolving environment.
• Drive high quality engineering standards including testing, documentation, peer review, and automation.
• Advocate for platform quality, reliability, supportability, and long-term maintainability.

Qualifications & Experience
