Job description

We are partnering with Singapore-based company that makes communication radios — not drones. looking for candidates with RF module/system-level design experience (not component-level, telecom, IoT, or semiconductor backgrounds), ideally with R&D and design-to-production experience within the last 5 years. They're open on seniority — individual contributors only.

About the Role

The Senior RF Engineer will play a critical hands-on role in designing, validating, and transferring high-performance radio modules from concept through production.

In this role, you will work closely with PCB, mechanical, and product engineering teams to develop advanced wireless systems used in demanding real-world environments. You will lead RF design execution from initial architecture through prototype validation and manufacturing transfer, ensuring designs meet performance, reliability, and manufacturability requirements.

This is a deeply technical role offering end-to-end ownership and direct impact on the performance and capabilities of client's wireless products.

What You’ll Do

• Design and develop production-ready RF radio modules from concept through validation and manufacturing transfer
• Translate product requirements into RF architectures including schematic design, RF front-end development, and PCB implementation
• Lead end-to-end RF design execution including RF circuitry, analog components, power supplies, and system interfaces
• Develop compact and scalable radio module designs that support multiple frequency bands and product configurations
• Perform RF simulations and front-end analysis to validate design decisions prior to hardware fabrication
• Plan and execute RF and system-level validation testing to ensure performance meets product specifications
• Prepare technical documentation including schematics, design rationale, and test results to support product lifecycle management
• Coordinate design reviews with RF, PCB, mechanical, and product engineering teams
• Identify technical risks and develop solutions balancing performance, cost, manufacturability, and schedule
• Support development of next-generation wireless technologies including advanced Wi‑Fi, BLE, GPS, and high‑power RF amplification systems

What Success Looks Like

• Delivery of validated RF radio modules that meet performance specifications and are ready for manufacturing
• Compact, flexible designs that support multiple SKUs and frequency configurations
• Efficient cross-functional collaboration with hardware, product engineering, and manufacturing teams
• Successful transfer of RF designs into production with minimal redesign requirements
• High technical rigor in RF design, testing, and documentation processes
• Strong contributions to next-generation wireless product development initiatives

Who You Are

• Bachelor’s or Master’s degree in Electrical Engineering, RF Engineering, or a related field
• Significant experience designing RF hardware for wireless communication systems
• Strong expertise in RF circuit design, front-end architectures, and radio system integration
• Experience with RF simulation, testing, and performance validation methodologies
• Familiarity with high‑frequency PCB design and RF layout considerations
• Experience supporting product development from prototype through production
• Ability to collaborate effectively with PCB designers, mechanical engineers, and product teams
