Radio-Controlled Mower Door Circuit -- 2

I'm looking for an experienced electrical engineer to design a sensor-based circuit for a swinging mower door. The door will be part of a fence system and should integrate seamlessly with a radio control mechanism.

Key Requirements:
- Design a sensor to break a normally open circuit
- Create a reliable radio-controlled mechanism for a swinging door
- Ensure safe and efficient operation

Ideal Skills and Experience:
- Expertise in analog and mixed-signal circuits
- Experience with radio communication systems
- Strong background in designing and implementing sensors

Please provide examples of similar work and estimated timelines.
