Validation Engineer - Service Assurance

You are an organized and credible validation professional who can bring structure to complex change, ask constructive questions and turn technical inputs into clear assurance and readiness decisions. You are comfortable working across cultures and time zones and can travel to terminal and stakeholder locations when required. 

Key responsibilities

• Coordinate end-to-end validation and assurance activities for Edge Platform products, services and deployments, including third-party solutions. 

• Maintain clear validation plans, assurance checklists, acceptance criteria, entry and exit criteria, and readiness gates aligned to agreed requirements and risk. 

• Confirm traceability from requirements and controls through test coverage, results, defects, operational evidence and final acceptance decisions. 

• Review the quality and completeness of validation evidence, challenge gaps and ensure decisions are supported by objective records. 

• Coordinate functional, resilience, performance, recoverability, security and operational readiness validation with the accountable subject matter experts. 

• Facilitate assurance reviews, validation workshops, defect triage, readiness checkpoints and service acceptance forums. 

• Ensure defects, deviations, risks, dependencies and non-conformances are recorded, owned, assessed and resolved or formally accepted before release. 

• Assess operational readiness across support models, monitoring, backup and recovery, documentation, runbooks, service management processes, access, training and handover. 

• Provide concise, evidence-based readiness summaries and recommendations, including clear conditions, residual risks and actions where acceptance is not yet appropriate. 

• Work with Platform Architects, Product and Engineering teams, Cyber Security, Operations, Service Management, regional IT and terminal IT to achieve quality outcomes. 

• Support independent assurance by respectfully challenging assumptions, identifying control weaknesses and escalating material gaps through the agreed governance route. 

• Define and maintain useful validation and assurance measures, including evidence completeness, defect status, readiness progress, exceptions and acceptance decisions. 

• Capture lessons learned and turn them into practical improvements to standards, templates, controls and ways of working. 

Essential skills and experience 

• Relevant experience in validation engineering, service validation, quality assurance, test coordination, operational readiness or service acceptance. 

• Experience supporting complex infrastructure, platform, operational technology or enterprise technology change in a multi-stakeholder environment. 

• Practical knowledge of validation lifecycle activities, test planning, assurance methods, acceptance criteria, evidence management, defect governance and readiness assessment. 

• Ability to interpret requirements, risks and controls and establish clear traceability to validation evidence and acceptance outcomes. 

• Working knowledge of ITIL practices and service transition or service acceptance governance. 

• Broad technical understanding of infrastructure and platform services, with the ability to coordinate validation and assurance across networks, compute, storage, virtualisation, backup, recovery, monitoring, observability and cyber security. 

• Experience producing validation plans, assurance packs, readiness reports, decision papers, dashboards or governance updates. 

• Strong analytical skills, attention to detail and confidence identifying gaps, inconsistencies and unsupported claims. 

• Clear written and verbal communication, with the ability to explain evidence, risk and readiness to both technical and non-technical audiences.
