• Engaging with engineering, operations and customer-facing stakeholders
• Supporting readiness assessments and acceptance milestones
• Managing and operating test environments across networking and infrastructure layers
• Ensuring conformance to requirements, standards and compliance obligations

• Experience in systems verification, validation, system integration, or system test roles
• Strong understanding of the systems V-Model lifecycle, particularly V&V activities
• Solid hands-on experience with Networking & Infrastructure
• Proficiency with Unix and Linux environments
• Experience in secure, mission-critical or defence-related environments
• Ability to work full-time on customer premises (5 days per week) due to the nature of the work and secure environment requirements
• Strong reporting and documentation capability
