Senior RF Engineer

Principal RF Hardware Engineer

We are hiring a Principal RF Hardware Engineer to serve as a technical leader for the design and architecture of our wireless products. In this role, you will own the RF architecture of a product family — spanning cellular (4G LTE, 5G NR Sub-6), GPS/GNSS, Antenna and cable selection for FWA, Industrial and Vehicular applications. Highly desirable: Wi-Fi (6/6E/7), and Bluetooth — Experience with end to end product design and NPI. production.

You will participate in the 2–3 year RF roadmap for your wireless products/product family, lead the most challenging technical work yourself, mentor Staff and Senior engineers, and partner closely with antenna vendors, systems, firmware, regulatory, and product teams to deliver best-in-class wireless performance.

This is a hands-on senior IC role for an engineer who enjoys deep technical work as much as architectural leadership — and who wants meaningful scope and influence without stepping fully out of design execution.

RF Architecture & Design

• Own the RF Integration of RF modules for a product family that integrates cellular (4G LTE / 5G NR FR1), Wi-Fi (2.4 / 5 / 6 GHz), GNSS (multi-constellation, multi-band — L1/L5), and Bluetooth radios. Ensure Co-exitance between integrated radio technologies.
• Lead module, cable, and antenna selection for multiple radios and matching network design across all supported bands.
• OwnModule integration performance maintaining 3GPP and regulatory compliance. Perform coexistence/desense studies for multi-radio platforms (LTE–WLAN, NR–GNSS, Wi-Fi–BT coexistence; harmonic and intermod analysis).
• Drive antenna integration strategy in partnership with major antenna Vendors and validate antennas
• Specify and review schematics and RF PCB stack-ups/layouts, including impedance-controlled routing, grounding, shielding, and isolation strategies. Verify any RF Circuit for S-Parameteters via modeling and measurements. Investigate sources of noise and mitigate.
• Own EMC regulatory compliance of systems with radio modules. Work with external EMC test labs to achieve regulatory certifications like FCC, CE and industry specific certifications like IEEE1613 and IEC-61850-3.

Technical Leadership

• Serve as the RF Technical Authority for wireless products, own resolution of the toughest desense, coexistence, and certification issues.
• Mentor Staff, Senior Staff, and other engineers on RF related topics ; help calibrate technical leveling and contribute to interviewing and hiring.
• Experience integrating high performance cellular data modules in large host platforms.
• Drive DFM/DFT for RF enabled products and subsystems

Bring-up, Validation & Certification

• Lead prototype bring-up and RF 3GPP Validation using Keysight UXM Cal box, Amari Network Emulator, VNAs, spectrum analyzers, signal generators, cellular/Wi-Fi testers (CMW500/CMX500, IQxel, Litepoint), and GNSS simulators (Spirent, Keysight).
• Define and execute RF compliance and performance test plans — conducted and radiated TRP/TIS/OTA, TX/RX characterization, EVM, ACLR, spurious emissions, blocking, and selectivity.
• Guide regulatory and operator certification programs: FCC, ISED, CE/RED, MIC, PTCRB, GCF, Wi-Fi Alliance, Bluetooth SIG, and Tier-1 carrier (Verizon, AT&T, T-Mobile,, NTT, etc.) approvals.
• Own field performance debug — RSRP/RSRQ/SINR analysis, throughput optimization, GNSS C/N₀ and TTFF tuning, and root-cause investigation.

What You'll Bring

Required Qualifications

• BS in Electrical Engineering (MS preferred) with emphasis on RF/microwave, communications, or wireless systems.
• 10+ years of RF hardware design experience, leading multi-radio products from concept to mass production.
• Deep, hands-on expertise across multiple of the following domains:

• Cellular: 4G LTE, 5G NR Sub-6, Wi-Fi: 802.11 a/b/g/n/ac/ax/be, MU-MIMO, OFDMA, 6 GHz operation, multi-band concurrent designs.
• GNSS: Multi-constellation, multi-band (L1/L5), active/passive antenna integration, assisted GNSS.

• Proven track record of shipping wireless products at scale through carrier and regulatory certification.
• Expert proficiency with RF lab instrumentation : VNA, SA, VSA, VSG, noise figure analyzer, power meter, cellular/Wi-Fi/GNSS testers, anechoic chambers.
• Strong command of RF simulation and EM tools : ADS, AWR Microwave Office, HFSS, CST, Sonnet, Cadence Allegro/OrCAD or equivalent.
• Solid understanding of PCB stack-up design, controlled impedance, EMI/EMC, and high-speed digital interfaces adjacent to RF (PCIe, USB 3.x, MIPI, DDR).
• Demonstrated ability to lead coexistence and desense engineering in dense, multi-radio platforms.
• Working knowledge of 3GPP specifications (TS 36.xxx / 38.xxx series) and IEEE 802.11 specifications

Preferred Qualifications

• Familiarity with NTN / satellite IoT, UWB, or RedCap.
• A track record of technical contribution — for example, a few issued or pending patents, conference papers, internal technical publications, or standards-body participation. We value demonstrated technical depth more than a specific count.
• Background in automotive (AEC-Q), industrial, and vehicular IoT form factors.
• CTIA test plan execution, or carrier lab campaign management.
