Diagnose and repair circuit card assemblies and assembled units, develop and integrate complex test solutions, and troubleshoot test systems to component level. Collaborate with the Test team and pursue continuous skills development and progression.

Lead firmware development and verification for safety-critical avionics mission computers using VHDL and FPGAs. Ensure compliance with RTCA/DO-254, lead design reviews, support system architecture, and contribute across the full development lifecycle while advancing team capabilities.

Perform systems engineering and cybersecurity work for LC5ISR-T: design system/security architecture, document requirements and interfaces, conduct vulnerability assessments and threat modeling, support integration/test and SPR management, produce SA&A artifacts (SSPs, risk assessments), and ensure compliance with NIST RMF, ITSG-33, DISA STIGs, and FIPS.

Design and prototype graphical user interfaces for military embedded devices and software within interdisciplinary teams. Develop low-to-high fidelity UX artifacts, define UI requirements, create development assets, prepare and review design documents, and document analysis, design and test activities following SAFe processes while coordinating closely with developers and human factors specialists.

Sell Tactical Communication and Information Systems internationally as a technical subject-matter expert. Capture customer requirements, deliver demos and POCs, support proposals and pricing, collaborate with product and engineering, act as post-sale technical escalation for upsell, and gather market and competitor intelligence. Travel internationally and support hybrid work from Oakdale, South Wales.

Lead and deliver high-quality, compliant proposals across the full bid lifecycle. Coordinate cross-functional inputs, develop win themes, manage timelines, governance and reviews, improve bid processes and support wider business activities.

Support engineering and production of military circuit cards: perform bring-up, circuit simulation and testing, component selection, root-cause investigations, test development, and support factory debugging. Learn from senior engineers and progress to schematic capture and design ownership.

Manage and monitor master production schedules, validate manufacturing deliverables and forecasts, identify capacity bottlenecks, prepare weekly/monthly schedules and status reports, coordinate cross-functional recovery plans, support BOE for bids, and ensure timely shipment of finished goods.

Develop and execute system verification and validation test plans in a lab and field environment. Configure systems, create automated tests, troubleshoot networks and radios, support external test events, review technical documentation, and collaborate with software, systems engineering, and customers in an Agile team.

Develop, test, and maintain mission-critical Air & Naval sonar software. Perform requirements analysis, design, coding (C++/Java), code reviews, troubleshooting, integration, validation, and documentation. Collaborate across teams, present at design reviews, follow Agile practices, use Linux and version control, and support stakeholders throughout the development lifecycle.

Design and deliver electro-mechanical assemblies from concept through verification for defence products. Produce 3D CAD models and drawings, support DFMA and BOM creation, lead design reviews, plan and execute environmental testing, develop assembly methods and tooling, mentor junior staff, manage configuration/change control, and collaborate with manufacturing and project teams to meet requirements, cost, schedule, and compliance.

Design and validate rugged mechanical components, subsystems, and enclosures for military platforms. Support full product lifecycle from requirements and concept through prototyping, environmental testing, manufacturing support, RCCA, and design reviews. Collaborate with cross-functional teams, mentor junior designers, and contribute to continuous improvement.
