Responsibilities

Own end-to-end performance of the magnetic sensing subsystem: signal chain, dynamic range, noise, saturation/clipping avoidance, and environmental robustness

Define sensor KPIs and verification methods (e.g., sensitivity, false alarm rate, drift, environmental robustness) and drive them through lab/field validation

Design, characterize, and match coils/sensor assemblies to improve gradiometer/common-mode rejection and repeatability

Define and execute calibration methods (factory and field), including fixtures, procedures, and acceptance criteria

Drive sensor-related mechanical requirements (alignment, stability, tolerance stack-ups) in partnership with ME/ID

Lead lab and field validation: test plans, data collection, root-cause analysis, and performance improvements

Characterize repeatability and unit-to-unit variation; support process capability improvements in manufacturing

Develop/debug embedded software supporting the sensor stack (device drivers, interfaces, timing/synchronization, signal integrity, and data integrity)

Build internal tools in Python for sensor data capture, analysis, diagnostics, and automated regression testing

Collaborate with ML/software teams on data quality, labeling workflows, and sensor-driven model improvements

Design manufacturing test and QC workflows for sensor assemblies (automated tests, calibration rigs, traceability)

Document procedures, requirements, and test results for engineering and operations teams

Required

B.S. in Electrical Engineering, Computer Engineering, Physics, or related field (or equivalent experience)

3+ years in sensor, signal chain, or embedded systems engineering (product-focused, hands-on)

Strong fundamentals in low-noise measurement, ADC/DAQ systems, and practical signal processing

Hands-on experience with analog front ends (AFE), filtering, grounding/shielding, and noise/EMI mitigation

Proficiency in C/C++ (embedded) and Python (tooling/data/test automation)

Experience with SPI/I2C, hardware bring-up, and debugging mixed hardware/software issues

Comfort working directly with electronics boards for bench testing, bring-up, probing, connectorization/rework as needed, and hands-on debugging

Ability to read schematics/datasheets and translate requirements into measurable specs

Preferred

Experience with magnetic sensing, gradiometry, EMI/EMC mitigation, and calibration under real-world interference

Embedded Linux experience (drivers, system services, data pipelines), NVIDIA edge platforms a plus

Experience building manufacturing tests and production calibration processes

Familiarity with Yocto, Docker, and modern CI/test practices

Experience supporting fielded systems (debugging, instrumentation, reliability improvements)
