Principal Antenna Engineer

I’m working with a specialist RF and antenna technology company based in Belfast that develops advanced antenna solutions for body‑centric, space‑constrained wireless applications, including wearables, medical devices and next‑generation IoT products.

Principal Antenna Engineer – taking a leading technical role within the engineering team. This position offers genuine technical ownership, hands‑on design responsibility and influence across R&D, product development and customer integration.

• Lead the design, simulation and optimisation of advanced antenna systems using EM tools such as CST Microwave Studio or equivalent
• Develop antenna solutions for body‑centric and RF‑challenging environments
• Design and evaluate RF front‑end elements including matching networks, filters and LNAs
• Perform antenna characterisation and validation using VNAs, anechoic chambers and other RF test equipment
• Support manufacturing and assembly process development to improve yield, repeatability and robustness
• Provide senior‑level technical support for customer integration, troubleshooting and performance tuning
