Senior RF Engineer

The Role

We are looking for a Senior RF Engineer to join our hardware team. Working closely with our Head of RF in Denmark, you will drive RF development, bring-up, and support from early prototyping through production validation.

• Drive RF development, bring-up, testing, and troubleshooting for Fortell's hearing aid products.
• Tightly collaborate with the Head of RF in Denmark to drive RF strategy, set development timelines, and make architectural decisions that keep the product moving forward.
• Define and optimize the RF front-end architecture, including antenna design, matching networks, and link budget optimization for Bluetooth Classic, Bluetooth Low Energy (BLE), and NFMI.
• Drive miniaturization and integration—finding ways to make the RF subsystem smaller, more tightly integrated, and more manufacturable without giving up performance.
• Read, review, and red-line schematics; collaborate with the electrical engineering team on Altium layout to ensure RF-critical placement, routing, and stackup decisions are correct.
• Build and run RF test and validation efforts—define test plans, operate bench equipment, collect chamber data, and close the loop between simulation and measured performance.
• Prototype and experiment hands-on: solder, rework, probe, and iterate quickly to resolve issues and prove out ideas.
• Support production RF validation and troubleshooting as products move into manufacturing.

What You'll Do

• Support production RF validation and troubleshooting as products move into manufacturing.

What We're Looking For

• Deep expertise in Bluetooth Classic and BLE RF implementation.
• Background in hearing aid, earbud, or ear-worn product development, with an understanding of the unique RF and form-factor constraints these products impose.
• Strong RF simulation skills (ideally CST Studio)—you use these simulation tools to make informed design decisions before committing to hardware.
• Expert-level electrical engineering skills: schematic capture, circuit analysis, component selection, and close collaboration with the electrical engineering team on PCB layout to minimize desense (Altium preferred).
• Hands-on prototyping and lab skills—comfortable with spectrum analyzers, network analyzers, oscilloscopes, and the full RF bench toolkit.
• Experience taking complex RF designs through the full product lifecycle: from architecture through validation and into production.
• High urgency and bias toward action—find ways to get answers fast, whether that means a quick bench experiment, a rough simulation, or a creative workaround, rather than waiting for perfect conditions.

Nice to Have

• Experience with regulatory testing and certification (FCC, CE, IC) for wireless devices.
• Familiarity with NFMI (Near-Field Magnetic Induction) systems—ideally in hearing aids, earbuds, or similar ear-worn devices.
