Operations Technician Role

As an Assembly Technician for Perception & Compute Payloads, you will be a hands-on contributor responsible for assembling, integrating, and validating Field AI’s sensing and compute payloads. You will build electro-mechanical subsystems, integrate sensors and embedded compute platforms, perform harnessing and power system checks, support functional testing, and ensure every payload is field-ready and reliable. This role bridges mechanical assembly, electrical integration, and practical system-level debugging. You will support both prototype development and production workflows while working closely with engineers to improve build processes and increase system reliability.

1. Payload Assembly & Integration

●     Assemble perception payloads including LiDAR, cameras, IMUs, GPS receivers, and auxiliary sensors using engineering drawings and build instructions.

●     Install and integrate CPU/GPU compute modules, carrier boards, and microcontroller-based subsystems.

●     Build and route wire harnesses for power, high-speed data, synchronization, and control.

●     Install mounts, enclosures, gaskets, seals, thermal components, and structural hardware.

2. Electrical, Power, and Communication Bring-Up

●     Perform continuity checks, grounding/EMI checks, and power-rail validation.

●     Assist in bring-up of Linux- or ROS2-based embedded compute systems.

●     Validate communication links across Ethernet, USB, CAN, GMSL, and other interfaces.

●     Verify correct pinouts and harness strain-relief practices.

3. System Testing & Quality Assurance

●     Run functional tests including sensor bring-up, calibration checks, compute boot/health tests, and network verification.

●     Document test results, deviations, rework, and repair actions with high accuracy.

●     Support environmental, vibration, mechanical alignment, and thermal characterization tests led by hardware engineers.

●     Conduct inspections for workmanship quality, mechanical stability, and electrical safety.

4. Debugging & Continuous Improvement

●     Diagnose wiring faults, mechanical misalignments, intermittent communication issues, thermal faults, and other integration failures.

●     Work closely with electrical, mechanical, and compute engineers to root-cause issues and improve build processes.

●     Provide feedback on assembly workflows, documentation clarity, and opportunities to streamline production.

5. Field & Operations Support

●     Prepare, stage, and service payloads for real-world deployment.

●     Support integration and troubleshooting activities during lab tests, field trials, and live demonstrations.

●     Perform rapid repairs and reconfigurations in dynamic testing environments.

●     2+ years of hands-on technician experience in robotics, aerospace, electronics, automotive, or related  electro-mechanical assembly environments.

●     Proficiency with hand tools, power tools, torque drivers, and basic machine-shop tools.

●     Ability to read and follow wiring diagrams, mechanical drawings, and assembly instructions.

●     Experience building wire harnesses and working with low-voltage electrical systems.

●     Familiarity with embedded compute systems, sensors, or robotics hardware.

●     Strong attention to detail, documentation discipline, and ability to deliver reliable assemblies.

●     Ability to lift up to 50 lbs. and work in workshop, lab, or field environments.

●     Experience working with perception systems such as LiDAR, cameras, radar, or IMUs.

●     Familiarity with Linux, ROS2, or embedded system bring-up workflows.

●     Soldering, crimping, or IPC-certified workmanship skills.

●     Understanding of thermal management, weather sealing, EMI/EMC basics, and ruggedized mechanical design.

●     Experience supporting prototype builds, rapid iteration cycles, or field test deployments.

●     Ability to design or suggest simple fixtures or jigs to improve assembly and repeatability.

●     Experience assembling complex electro-mechanical systems, especially robotics, drones, or ruggedized field hardware.
