• Conduct RF system analysis, performance optimisation, and troubleshooting of complex designs.
• Conduct simulation and modelling of RF circuits using tools like ADS, CST, MWO or similar
• Carry out RF measurements, characterisation, and validation of prototypes and production hardware.
• Develop and maintain detailed technical documentation, including design reports, test plans, and results.
• Ensure designs meet required specifications, standards, and customer requirements.
• Contribute to technology and product roadmaps with innovative RF design solutions.
• Support RFQs, proposals, and customer engagements with technical input where required.

Project & Product Management:

• Work with project managers and engineering leads to deliver designs on time, within budget, and to agreed quality standards.
• Support the transition of designs from concept through prototyping into volume manufacturing.
• Collaborate with process engineering and operations to ensure manufacturability and yield of RF products.
• Assist in risk identification and mitigation during the design and development process.

Collaboration & Communication:

• Support a culture of innovation, knowledge sharing, and continuous professional development.

ESSENTIAL

• Degree (or equivalent) in Communications/Electronic Engineering, Physics, or a related discipline.
• Significant hands-on experience in RF and/or mmWave design, simulation, and test.
• Strong knowledge of RF CAD tools (e.g., ADS, AWR, CST, or similar).
• Proven track record in RF circuit and subsystem development (LNAs, PAs, filters, mixers, oscillators, etc.).
• Experience in RF measurement techniques and use of VNAs, spectrum/network analysers, and test automation.
• Strong problem-solving ability and analytical skills.
• Excellent communication and teamwork skills.

DESIRABLE

• Experience in high-frequency design (Ku, Ka, Q, V and E-band).
• Familiarity with volume manufacturing processes and DFM/DFT.
• Experience working to quality standards and regulatory requirements.
