Electro-Optical Technician Santa Clara, CA (Onsite) The Opportunity We are seeking a hands-on Electro-Optical Technician to support electrical board rework, troubleshooting, board bring-up, test, and assembly of next-generation spectroscopy platforms and gas measurement products. Picarro’s products deliver real-time measurements of critical gases at parts-per-billion and parts-per-trillion levels. As an Electro-Optical Technician, you will work closely with engineering, manufacturing, and test teams to bring up prototype and production circuit boards, perform precision board-level rework, troubleshoot electrical and electro-optical issues, and support the integration of electronics into high-performance CRDS instruments.

Optical assembly experience is valuable in this role, but the primary focus is hands-on electronics support, board debug, and reliable execution in the lab. The Ideal Candidate The ideal candidate is a detail-oriented technician with strong hands-on experience in PCB rework, electrical troubleshooting, board bring-up, and lab-based hardware support. They are comfortable working under a microscope, replacing fine-pitch components, probing analog and digital circuits, using standard electrical test equipment, and documenting issues clearly.

This person can follow schematics, assembly drawings, test procedures, and engineering direction while also applying practical judgment to isolate faults and recommend next steps. Experience with optical assemblies, fiber handling, alignment, or precision mechanical assembly is important and will be used regularly.

Key Responsibilities

Support the building, rework, bring-up, troubleshooting, and integration of electro-optical hardware for Picarro’s CRDS products. Perform board-level rework and repairs, assist with prototype and pilot builds, execute electrical tests, document findings, support root-cause investigations, and contribute to reliable handoff of hardware, processes, and test methods into manufacturing. Technical Expertise: PCB Rework and Repair : Perform high-quality board-level rework, including component removal and replacement, jumper wires, trace repairs, connector work, fine-pitch soldering, and microscope-based inspection.

Board Bring-Up : Support first-power-on, functional checkout, calibration setup, and debug of prototype and production PCB assemblies using engineering instructions and test procedures. Electrical Troubleshooting : Use schematics, layout files, DMMs, oscilloscopes, power supplies, signal generators, and other lab equipment to diagnose board-level and system-level electrical problems. Electro-Optical Integration : Install, connect, and test electronics within electro-optical assemblies, including detector boards, laser-related electronics, cables, harnesses, sensors, and related hardware.

Test, Debug, and Root Cause Support : Execute engineering tests, collect data, record observations, help isolate failure modes, and support corrective actions for build, rework, and bring-up issues. Optical and Precision Assembly Support : Support optical assembly, fiber handling, alignment, adhesive bonding, mechanical assembly, and clean handling practices as needed for electro-optical systems. Prototype and Pilot Build Support : Assist with prototype builds, pilot builds, ECO implementation, fixture setup, cable and harness work, and transition of repeatable processes into manufacturing.

Documentation and Communication : Maintain clear rework records, bring-up notes, test results, nonconformance details, and build documentation; communicate issues and status clearly to engineering and manufacturing teams.

Qualifications

and Experience Associate degree, technical certificate, military electronics training, or equivalent hands-on experience in electronics, electro-mechanical assembly, test, or related technical work.
