Wireless System Engineer

Principal Engineer (Wireless Location Algorithm)- role for one of our clients, a wireless services company, this is a full time role located in Belmont, CA.

They’ve developed a platform that can locate devices in real time using wireless signals — no GPS needed. That means it works indoors, underground, or anywhere GPS fails. The role will be all about signal processing and advanced algorithms. It’s a small, sharp team where your work directly shapes the tech.

If you’re someone who enjoys solving hard signal problems, this would hit the mark!

Qualifications:

PhD or Masters in Electrical Engineer

Expertise in the characteristics and nuances of key wireless technologies used for positioning, primarily in WiFi Technology

Strong understanding of wireless systems and protocols (IEEE 802.11 standards)

Strong background in communication theory and digital signal processing (DSP): Understanding concepts like modulation, coding, channel estimation, filtering, and signal detection

Understanding of TDoA (Time Difference of Arrival) and related location techniques.

Python and NumPy

Knowledge of RF hardware

Responsibilities:

Creating innovative algorithms for wireless positioning, often using techniques like trilateration, triangulation, sensor fusion (combining data from different sensors like Wi-Fi, Bluetooth, UWB, GPS, IMUs), and probabilistic methods (e.g., particle filters).

Build custom test fixtures to benchmark system and components

Building and using computer models (often in MATLAB, Python, or C++) to simulate wireless environments and test the performance of their algorithms under various conditions

Prototype improvements to existing location estimation techniques and adapt them to new industry standards

Analyzing and resolving issues related to location accuracy and system performance in complex wireless environments
