About The Position

Rochester Sensors, an Amphenol Company, develops sensors for various industries including industrial, heavy vehicle, power generation, and storage. They are expanding their sensor expertise and in-house technologies to create engineered solutions. Rochester is a multinational company with headquarters in Dallas, Texas, and manufacturing facilities across the USA, Mexico, Belgium, the UK, Ireland, and China. They focus on building quality, accuracy, and reliability into their products, which are sold to OEMs and distributors in markets such as Agricultural, Aircraft, Automotive, Refrigeration, Industrial, LP Gas, Marine, Heavy Truck, Off-Road, Construction, Locomotive, Petrochemicals, and Process Equipment. This specific role is for a Senior / Principal Electrical Engineer to architect and develop next-generation liquid level sensing systems for demanding heavy vehicle and off-road environments. The role requires a deep technical expert who has designed sensors from first principles and taken them to production. Responsibilities include developing advanced sensing technologies like Guided Wave Radar (GWR), Capacitive sensing, and Ultrasonic sensing, ensuring reliable operation in extreme mechanical and environmental conditions. The position is hands-on, requiring ownership of the sensing architecture from physics through production, covering electronics, signal processing, environmental robustness, and system integration. Products developed in Dallas will be deployed globally in construction, agriculture, mining, commercial vehicle, and industrial markets. The position requires the candidate to be located in the DFW area and is not a remote position.
