Senior NPI Engineer - Optomechanical SystemsSanta Clara, CA
The OpportunityWe are seeking an experienced, hands-on NPI Engineer to lead the transition of next-generation spectroscopy products from prototype through pilot build and into volume manufacturing.
Picarro's products deliver real-time measurements of critical gases at parts-per-billion and parts-per-trillion levels. In this role, you will take ownership of translating advanced CRDS-based optomechanical designs into robust, scalable, and high-yield manufacturing processes.
You will operate at the critical interface between R&D and manufacturing-driving productization strategy, leading build execution, and ensuring that complex optical systems can be manufactured with precision, repeatability, and cost-effectiveness.
This position reports to the Director of Spectrometer Engineering.
The Ideal CandidateThe ideal candidate is a seasoned productization / NPI engineer who thrives in ambiguity and takes full ownership of getting products into production.
- Leads by example as a hands-on builder and problem solver
- Owns complex builds and drives issues to closure across disciplines
- Influences design decisions to ensure manufacturability
- Creates processes, tooling, and documentation from first principles
- Acts as a technical bridge between engineering, manufacturing, and suppliers
- Is comfortable leading builds, mentoring junior engineers and technicians, and making technical trade-offs that balance performance, manufacturability, and cost.
Key ResponsibilitiesNPI Leadership & Product Transfer Ownership- Lead NPI from prototype through pilot build and production ramp
- Own engineering builds from prototype to early production
- Drive alignment across R&D, operations, quality, and supply chain
- Ensure successful transfer to manufacturing with clear ownership of yield, quality, and readiness
Design for Manufacturability & Productization- Lead DFM/DFA/DFX to optimize manufacturability, reliability, and cost
- Influence design through tolerance, alignment, and process constraints
- Identify high-risk areas early and drive design and process changes
Process Development & Industrialization- Develop and validate assembly processes for precision optomechanical systems
- Define process flows, controls, and acceptance criteria
- Establish repeatable alignment processes and production windows
- Lead tooling and fixture strategy and validation
Pilot Builds & Manufacturing Readiness- Plan and lead EVT/DVT/PVT builds, including line setup
- Analyze yield, variation, and failures; drive root cause and corrective actions
- Own production readiness reviews and release criteria
Supplier & Manufacturing Interface- Lead contract manufacturer and supplier engagement for production readiness
- Drive supplier selection, qualification, and process alignment
- Resolve technical issues across internal and external manufacturing
Documentation & Process Control- Own manufacturing documentation, including:
- Work instructions
- Process flows and control plans
- Test procedures and validation reports
- Ensure robust configuration control and change management (ECO/PLM)
- Establish scalable documentation standards across programs
Production Ramp & Continuous Improvement- Own technical support during early production ramp
- Drive yield improvement, cost reduction, and process robustness
- Establish feedback loops between production, design, and suppliers for continuous improvement
Technical Leadership & Mentorship- Serve as a technical leader for NPI and productization activities within the team
- Mentor junior engineers and technicians in build practices, debugging, and process development
- Set technical standards for assembly, alignment, and manufacturing processes
Technical Expertise- Strong hands-on experience with high-precision optomechanical systems
- Expertise in optical alignment (active/passive), micron-level tolerances, and stability
- Deep understanding of optical components (lasers, detectors, coated optics, isolators)
- Experience with advanced attachment techniques (epoxies, soldering, welding)
- Strong background in debugging complex electro-opto-mechanical systems
- Experience with process validation, yield analysis, and root cause methodologies
Qualifications- BS/MS in Physics, Optical Engineering, Mechanical Engineering, or related field
- 4-7+ years of relevant experience in the industry
- Proven experience leading NPI/productization efforts for complex hardware systems
- Demonstrated ownership of pilot builds and manufacturing transfer
- Strong cross-functional leadership and communication skills
Preferred- Experience with spectroscopy or precision optical instrumentation
- Experience working with contract manufacturers and supply chains
- Familiarity with cleanroom or precision assembly environments
- Experience with DOE, PFMEA, SPC, or other process control methodologies
