Description
Ring is seeking a RF De-sense Engineer to join our Connectivity RF team. This role is critical to ensuring industry-leading wireless performance by identifying, debugging, and resolving RF de-sense, EMI, and coexistence issues across Ring products.
You will work in a fast-paced, cross-functional environment and collaborate closely with RF, system, baseband, antenna, mechanical, and manufacturing teams. The ideal candidate is hands-on, detail-oriented, and capable of owning complex RF de-sense challenges from early architecture through mass production.
Key job responsibilities
In this role, you will be responsible for de-sense and RF system validation activities as follows:
- Own RF de-sense, EMI, and wireless coexistence analysis across WiFi, BT, GNSS, LTE, and other radios.
- Drive system-level architecture reviews with a focus on noise mitigation, grounding, shielding, and layout best practices.
- Perform RF de-sense and EMI simulation and analysis using CST Studio Suite to predict noise coupling paths, validate mitigation concepts, and correlate simulation results with lab measurements.
- Identify, debug, and resolve de-sense root causes related to digital noise, power integrity, clocks, interfaces, and mechanical structures.
- Work closely with RF HW, antenna, baseband, power, and mechanical teams to implement effective mitigation solutions.
- Define de-sense validation strategies, test plans, and acceptance criteria for EVT / DVT / PVT / MP stages.
- Perform hands-on RF and EMI testing, data analysis, and performance optimization.
- Support second-source component qualification from a de-sense and EMI perspective.
- Act as the technical owner for de-sense issues, coordinating internal engineering teams and driving closure.
- Provide production line support and on-site debugging when required.
A day in the life
You must be responsive, flexible and able to succeed within a fast-paced environment. In this role, you will be responsible for RF hardware design activities and ODM activities.
About The Team
