Detection Subsystem Hardware Engineer

We’re looking for a Senior Detection Subsystem Engineer to own the full lifecycle of detection technology across our trail camera product line - from PIR signal processing to on-device AI classification and beyond. You’ll serve as the technical authority on how our cameras sense and respond to wildlife and other subjects, with a mandate to keep Moultrie’s detection capabilities ahead of the market.

This hands-on leadership role blends hardware, firmware, and applied machine learning, and puts you at the table for critical architectural decisions across product, engineering, and executive stakeholders., Technical Leadership

• Own the detection subsystem architecture - sensor technology, signal processing, AI inference strategies, and system-level trade-offs
• Define the multi-generation detection roadmap with product and engineering leadership
• Set standards and best practices; mentor junior and mid-level engineers

Detection Technologies

• Own end-to-end PIR subsystem design including sensor selection, Fresnel optic design, sensitivity tuning, and false-trigger mitigation
• Design and tune signal processing pipelines
• Lead on-device AI pipeline development - model selection, edge quantization, and integration with low-power embedded platforms
• Define and track key KPIs: detection range, trigger latency, false positive/negative rates, and power consumption

Hardware, Integration & Validation

• Select and qualify PIR sensors, optics, signal conditioning circuits, and AI inference hardware
• Partner with mechanical and electrical engineers on sensor placement, thermal shielding, and enclosure design
• Own the Verification and Validation strategy - including automated test frameworks, hardware-in-the-loop rigs, and field validation protocols across diverse environments and target subjects
• Maintain defect tracking and root cause analysis; partner with QA and product to validate fixes

Future Technology & Cross-Functional Work

• Research and prototype emerging technologies
• Author roadmap proposals and present to engineering and executive stakeholders
• Represent the detection subsystem in program reviews; support manufacturing with test fixture design and yield optimization

• Bachelor’s or higher in Electrical Engineering, Computer Engineering, Physics, or related field; advanced degree preferred
• 8+ years in embedded hardware/firmware development focused on sensing or detection systems
• Deep hands-on PIR experience: analog front-end design, signal processing, pyroelectric signal characterization
• Proven experience deploying ML/AI models on edge devices (TensorFlow Lite, ONNX, or similar)
• Proficiency in C/C++ for embedded firmware; strong low-power design fundamentals
• Experience building Verification and Validation frameworks including automated test and field validation
• Strong communicator with technical and non-technical audiences

Preferred

• Experience with radar sensor modules (TI mmWave, Infineon BGT series) or other non-optical detection technologies
• Familiarity with RTOS environments (FreeRTOS, Zephyr, etc.)
• Experience training or fine-tuning computer vision models (YOLO, MobileNet, EfficientDet) for wildlife or object classification
• Background in outdoor, ruggedized consumer electronics or IoT products
• Knowledge of PIR Fresnel lens or thermal imaging optics
• Experience with schematic review and PCB design
• Prior tech lead or mentorship experience; familiarity with IP/patent process
