Job Description

As an RF Systems Engineer, you will engage with an experienced cross-disciplinary staff to conceive and design innovative consumer products. You will work closely with an internal inter-disciplinary team, and outside partners to drive key aspects of product definition, execution and test. You must be responsive, flexible and able to succeed within an open collaborative peer environment.

As part of the RF Systems Integration team, you will be responsible for wireless design and integration at Lab126. This includes the development and optimization of various wireless technologies including LTE, GPS, 802.11 (WiFi), Bluetooth, UWB and other IoT technologies.
In this role you will:
- Work within a project team and take responsibility for the WiFi, BT implementation
- Meet with vendors and technology suppliers to select components
- Simulate, implement, validate and optimize RF circuits (including schematic capture and PCB layout)
- Characterize and debug desenseand EMI issues to meet requirements
- Perform multi-radio coexistence mitigation (including RF link budget planning and issue debugging)
- Perform simulations for RF design and desense mitigation (3D EM and circuit level simulations)
- Take the product through development, compliance testing, operator testing, ramp up and sustaining
- Support radiated manufacturing test and defects in the factory
- Work with software, mechanical engineering, baseband and compliance teams



Key job responsibilities
• Design RF systems for multi-radio integration (Wi-Fi, BT, cellular, satellite, GNSS, UWB, NFC) in compact devices.
• Develop RF sensing solutions: ranging, localization, radar-based presence and occupancy detection
• Define and close TX/RX chain link budgets, including cellular, satellite (NTN), and sub-1GHz long-range links.
• Analyze and mitigate multi-radio coexistence, desense, and blocker effects
• Support RF compliance and carrier certification (FCC/CE/TELEC/MIC, PTCRB/GCF) from design phase through mass production.
• Develop reusable multi-radio and RF-sensing reference designs that scale across the device portfolio.
• Partner cross-functionally with firmware, antenna, algorithms/ML, compliance, PM, and silicon/module vendors to ship on schedule.

Basic Qualifications:

- 4+ years of working in mechanical engineering or equivalent experience
- Experience with prototyping and implementation

Preferred Qualifications:

- Knowledge of SolidWorks simulation or Ansys Finite Element analysis tools
- Experience in the design of complex mechanical products and equipment at volume
