Electrical Engineering, Electronics Engineer, Test Engineer
Job Description & How to Apply Below
Location: Los Angeles, CA or Louisville, KY
About the workDevelop the sensing electronics and test infrastructure that let Astra Sense observe degradation in motors, inverters and high-voltage wiring. Connect physical measurements with labeled datasets and requirements-based engineering evidence.
What you will do- Design sensor front ends and signal conditioning for requirements-driven voltage, current, temperature, vibration and acoustic channels.
- Evaluate target measurement ranges of 0–450 V, −400 to +200 A, temperature channels up to 215 °C and vibration up to ±50 g. Confirm channel specifications, isolation and measurement uncertainty before selecting hardware.
- Develop insulation-monitoring and electrical-noise/EMI sensing approaches for the selected high-voltage subsystem.
- Build instrumented motor/inverter benches and controlled degradation or fault-injection experiments under approved high-voltage laboratory procedures.
- Measure harmonics and electrical noise; deliver labeled datasets with calibration, operating-condition, timestamp and provenance records to the AI team.
- Plan subsystem operation against the −40 °C to +85 °C environmental target and applicable DO-160 qualification objectives. Distinguish planned qualification from completed evidence.
- Document schematics, PCB designs, test procedures, anomalies and changes, and coordinate data-quality checks with modeling and embedded engineers.
- BS/MS in electrical engineering, plus at least three years in power electronics, motor drives or high-voltage systems.
- Analog front-end and PCB-design experience, including safe high-voltage laboratory practice.
- Hands-on inverter/motor testing with oscilloscopes, power analyzers and data-acquisition equipment.
Insulation-resistance or partial-discharge monitoring, EMI/EMC testing, DO-160 work, EV powertrains or eVTOL-related engineering.
First 90 days: scope to agreeAgree a first-90-day objective: an instrumented bench and an approved experiment that produce a traceable dataset for a selected insulation or harmonic fault mechanism. Confirm safety review, equipment, channel ranges and labeling criteria before committing the scope.
About Astra QuaAstra Qua is developing a modular autonomy architecture with AQFM as its shared intelligence foundation. Specialized agents contribute perception, reasoning, health and coordination. Astra Sense is the health‑intelligence agent, with electrified aviation as an initial research application; it connects condition and remaining capability with mission decisions. Our approach to safe AI emphasizes defined operating boundaries, deterministic safety controls, operator authority and behavior designed for verification and validation.
