KEY RESPONSIBILITIES
- Own test design and execution for assigned workstreams across the client’s estate.
- Review requirements, HLDs, LLDs, and project documentation to identify test scenarios and coverage gaps.
- Produce and peer-review test scripts, test cases, and execution evidence to sign-off standard.
- Lead defect triage, root-cause analysis, and retest coordination across delivery, design, engineering, and operations teams.
- Validate System Integration, Functional, Non-Functional, Disaster Recovery, and Operational Acceptance test coverage before execution windows open.
- Provide technical guidance and mentoring to Test Engineers; raise the standard of scripts, evidence, and defect records across the workstream.
- Maintain ALM discipline: test case structure, requirements traceability, defect lifecycle, and reporting accuracy.
- Execute and lead complex testing across routers, switches, firewalls, hosting, data centre, LAN/WiFi, SD-WAN, UC & Unity, telephony, mobility, MPN & Cloud, IoT, fixed connectivity, cloud & security, and service transition.
- Set up and validate complex test environments, including network test equipment and RFC 2544 performance testing where required.
- Support Test Managers with status reporting, risk identification, defect trend analysis, and milestone readiness assessments.
- Represent testing in technical design discussions, ensuring testability is considered in HLD/LLD reviews.
- Interface confidently with client stakeholders and customer representatives in test working groups and triage calls.
- Escalate risks and blockers within the same working day, with proposed mitigations rather than bare problems.
- Drive reuse: contribute and curate test assets, automation candidates, and AI-assisted test design patterns supporting the programme’s productivity commitments.
- Support onboarding, knowledge transfer, and continuity across joiners and leavers with no impact to the Project Test Plan.
- Comply with client security policy, data handling, and audit requirements at all times, on and off site.
- Attend client hubs and customer sites as required, including liaison with the wider Test team and, where applicable, the customer lab.
TECHNICAL SCOPE & DOMAIN COVERAGE
Testing services are delivered across the full client product and service estate: Hosting; LAN & WiFi; Data Centre; Service Transition; SD-WAN; Telephony; UC & Unity; MPN & Cloud; IoT; Fixed Connectivity; Mobility; Cloud & Security.
Test phases in scope: Unit Testing, System Integration Testing (SIT), Functional Testing, Non-Functional Testing, Disaster Recovery Testing, and Operational Acceptance Testing (OAT).
Deep hands-on telecom/network infrastructure testing: routers, switches, firewalls, Cisco console competence.
Strong technical understanding across hosting, data centre, SD-WAN, LAN/WiFi, UC, mobility, cloud & security, and service transition.
Ability to interpret complex infrastructure designs and translate them into structured, traceable test scenarios.
Advanced ALM usage: coverage modelling, traceability, defect analytics, and management reporting.
Performance and conformance testing: RFC 2544, network test equipment, service management toolsets (e.g., StableNet).
MANDATORY SKILLS & EXPERIENCE
- Minimum 5 years’ relevant experience, with demonstrably deeper hands-on telecom/network testing than the Test Engineer band.
- Strong QA and test industry knowledge of standards and methodologies.
- Proven test design ownership on complex infrastructure or service transition programmes.
- Strong defect management, root-cause analysis, and test evidence discipline.
- Excellent organisational, coordination, and stakeholder management skills, comfortable in customer-facing settings.
- Proficient Excel and strong Microsoft Office, Teams, and SharePoint skills.
DESIRABLE SKILLS & EXPERIENCE
- Experience in customer-facing or critical infrastructure environments (CNI / National Grid advantageous).
- Test automation experience and AI-assisted test design exposure.
- Experience mentoring or technically leading small test teams.
- ITIL working experience.
- Multi-domain breadth across three or more of the twelve domains.
CERTIFICATIONS & QUALIFICATIONS
- ISTQB Foundation – expected.
- ITIL – desirable.
- Relevant network/cloud certifications (e.g., CCNA/CCNP, cloud provider certs) are desirable
