Sr. Radio Frequency Hardware Engineer
About the role
We are seeking a Senior RF Engineer to join our multidisciplinary team developing mission-critical RF/electrical systems for unmanned platforms. This role offers a rare opportunity to gain deep insight into RF design and validation, contributing across the full product lifecycle, from early concept and prototyping through production.
Responsibilities
- Lead the development of innovative solutions that span across RF, Mixed signal and mechanical domain.
- Design RF hardware as well as wireless testbeds to support system validation, and lead the execution and documentation of system-level design and verification.
- Provide expertise, mentorship to partner teams regarding EMI mitigation strategies, and cross-functional debug processes.
- Characterize EMI caused by internal & external aggressors by tracing root causes using EMC probes, shielding tests, grounding checks, and layout reviews.
- Conduct rigorous lab and OTA testing of RF systems, including sensitivity and coexistence evaluations across LTE, 5G NR, Wi-Fi, GNSS, and validate performance against industry standards.
- Perform EM simulations using CAD tools (CST, HFSS, ADS) to develop deep understanding of product behavior and drive informed design decisions.
- Clearly communicate technical challenges, gaps and trade-offs to fellow engineers and executives.
Requirements
- Bachelor’s or Master’s degree in Electrical Engineering, with specialization in RF engineering, applied electromagnetics, or wireless systems.
- 6+ years of hands-on experience in designing and testing RF hardware for consumer grade mass-produced products.
- Strong RF fundamentals with expertise in front-end design, desense analysis and system-level optimization.
- Experience working with systems that include high-speed digital interfaces such as MIPI CSI / DSI, PCIe, DDR, SDIO / eMMC.
- Proficient in the use of RF test and measurement equipment, including oscilloscopes, spectrum analyzers, and network analyzers.
- Hands-on expertise in desense mitigation techniques, including shielding, grounding, and filtering, leveraging both simulation and empirical measurement data to drive root cause analysis.
- Excellent data analysis, report writing, presentation skills, and desire to work in fast-paced environment.
Qualifications
- Hands-on experience in RF hardware design and testing for consumer-grade products.
