Company

hirify.global develops multimodal artificial intelligence and next-generation hardware designed as a unified interface for interacting with people and the real world.

What you will do

• Design RF architectures, front-end lineups, link budgets, component selections, schematics, and PCBs for cellular, Wi-Fi, Bluetooth, GNSS, NFC, or UWB radios.
• Review RF layouts, routing, impedance control, grounding, shielding, and isolation strategies across PCB and flex designs.
• Plan and execute conducted, OTA, desense, and multi-radio coexistence validation; analyze results and optimize designs.
• Lead system-level RF failure analysis, root-cause investigations, and corrective actions.
• Drive factory RF calibration, test-station bring-up, test limits, yield analysis, and correlation from EVT/DVT/PVT through mass production.
• Own regulatory and carrier certification activities and coordinate with antenna engineers, vendors, test labs, carriers, and cross-functional stakeholders.

Requirements

• BS in Electrical Engineering or a related field with 5+ years of RF hardware design experience, or MS with 3+ years.
• Hands-on experience designing at least one wireless technology: 5G NR/LTE, Wi-Fi, Bluetooth, GNSS, NFC, or UWB.
• Strong understanding of transmission lines, impedance matching, RF front-end architecture, link budgets, noise, and linearity.
• Experience with vector network analyzers, spectrum analyzers, signal generators, communication testers, and OTA anechoic chambers.
• Experience taking a wireless product through at least one complete development cycle to mass production.

Nice to have

• MS or PhD in RF/microwave or wireless communications.
• Experience with FCC, ISED, CE RED, PTCRB/GCF, carrier acceptance, RF simulation, factory calibration, and OTA test development.
• Python, MATLAB, or SCPI instrument-control scripting experience.
• Knowledge of antenna design, tuning, CTIA OTA measurements, and multi-radio coexistence mitigation.

Culture & Benefits

• Work on multimodal AI systems and consumer hardware developed together as a unified product.
• Collaborate with antenna, mechanical, firmware, manufacturing, vendor, laboratory, and carrier partners.
• Total compensation may include additional components and benefits depending on the role.
