ROLE SUMMARY

We are looking for an RF Engineer to join our antenna design and validation team. This is a hands-on engineering role covering the full lifecycle of antenna product development, from matching network design and PCB-level RF debugging through to performance validation and measurement campaigns. You will work closely with our internal engineering team and engage directly with OEM customers on technical integration challenges, antenna characterisation, and product optimisation. This is a great opportunity for an RF engineer who wants broad exposure across antenna design, test, and customer-facing applications engineering.

KEY RESPONSIBILITIES

Design and optimise antenna matching networks (Pi, L-network) using Smith chart analysis and VNA measurements

Perform antenna characterisation including return loss, VSWR, radiation efficiency, gain, and TRP/TIS measurements

Conduct PCB-level RF debugging and support antenna integration reviews for OEM customer designs

Participate in antenna design reviews and contribute to product development from concept through to mass production

Execute antenna chamber testing and measurement campaigns, and document results in detailed technical reports

Engage with OEM customers as a technical engineering resource, supporting antenna integration and resolving performance issues

Evaluate PCB stackups and CPW/microstrip transmission line designs for RF performance

Solder and assemble RF test boards, antenna prototypes, and evaluation samples

Assist with incoming quality inspection and supplier technical evaluations for antenna and RF components

Contribute to root cause analysis and corrective action for field and customer technical issues

REQUIRED SKILLS AND EXPERIENCE

Solid understanding of antenna theory, matching network design, and RF fundamentals

Hands-on experience with RF test and measurement equipment (VNA, spectrum analyser, signal generator)

Proficiency in Smith chart analysis and impedance matching techniques

Experience with antenna test methods including return loss, VSWR, radiation pattern, and efficiency measurement

Ability to read, interpret, and review RF schematics and PCB layouts

Familiarity with PCB transmission line design (CPW, microstrip) and stackup considerations

Proficient soldering skills including SMD components and RF connectors (MHF, U.FL, SMA)

Strong technical documentation and reporting skills

Good written and spoken English for customer and partner technical engagement

PREFERRED / NICE TO HAVE

Experience with cellular antenna testing and validation (LTE, 5G NR, Cat-M, NB-IoT)

Familiarity with GNSS, BLE, Wi-Fi, or ISM band antenna products

Experience in an applications engineering or technical support role with OEM or module manufacturers

Knowledge of 3GPP standards or OTA test methodologies (CTIA, PTCRB)

Experience with LDS, FPC, or embedded antenna product types

Simulation experience with tools such as HFSS, CST, or similar

WHAT WE OFFER

Flexible working hours to support work-life balance

20 days of paid annual leave per year

Company performance bonus scheme

Monthly phone bill allowance covered by Synzen

Broad exposure to antenna design, test, and product development across multiple technology domains

Direct involvement in product development from early design stage through to mass production

Collaborative, technically driven team environment
