Opto-Mechanical Engineer II

<h2><strong>Opto-Mechanical</strong><strong> Engineer II &nbsp;</strong></h2> <p>Santa Clara, CA<strong> </strong>(Onsite)</p> <h3>The Opportunity</h3> <p>We are seeking a hands-on, mid-level Opto-Mechanical Engineer to help design, build, align, test, and productize next-generation spectroscopy platforms and gas measurement products.</p> <p>Picarro’s products deliver real-time measurements of critical gases at parts-per-billion and parts-per-trillion levels. As an Opto-Mechanical Engineer II, you will join a world-class team developing high-precision systems based on Cavity Ringdown Spectroscopy (CRDS), broadband lasers, and advanced optomechanical assemblies. This role is intended for an engineer who can contribute independently to defined design, build, test, and troubleshooting activities while continuing to grow into broader technical ownership. The position reports to the Director of Opto-Mechanical Engineering.</p> <p><strong><u>The Ideal Candidate</u></strong></p> <p>The ideal candidate is a practical, hands-on engineer with solid fundamentals in mechanical design, optical alignment, precision assembly, and experimental troubleshooting. They are comfortable working in the lab, building and debugging complex electro-optomechanical systems, and using data to drive design and process improvements. This individual can own well-scoped technical tasks, collaborate effectively with senior engineers, technicians, manufacturing, and suppliers, and communicate findings clearly. The right person is curious, detail-oriented, and motivated to develop manufacturable, reliable, high-performance products at the intersection of optics, mechanics, electronics, and spectroscopy.</p> <h3>Key Responsibilities</h3> <p>Contribute to the design, build, integration, and transfer of advanced electro-optomechanical systems for Picarro’s next-generation CRDS products. Support prototype and pilot builds, develop and refine assembly and alignment processes, create practical tooling and fixtures, document procedures, troubleshoot build and test issues, and work with cross-functional teams to improve performance, manufacturability, reliability, and yield.</p> <p><strong>Technical Expertise: </strong></p> <ul> <li><strong>Hands-On Opto-Mechanical Engineering</strong>: Build, align, test, and troubleshoot high-precision optomechanical assemblies while contributing to design improvements and process development.</li> <li><strong>Optical Component Expertise</strong>: Work with near-infrared optical components such as lasers, detectors, isolators, fiber components, mirrors, lenses, filters, and coated optics.</li> <li><strong>Precision Design and Alignment</strong>: Apply sound mechanical design, tolerancing, ma
