Systems Integration Engineer

Picarro, Inc • Santa Clara, CA

12h • $120,000 - $130,000 • Onsite

About The Position

We are seeking a Systems Integration Engineer to support the prototyping, validation, and transition to production of the next generation of Cavity Ring-Down Spectroscopy (CRDS) gas analyzers. This role sits at the intersection of optics, opto‑mechanics, electronics, firmware, and software, with a strong emphasis on system-level testing, debugging, and productization.
The ideal candidate is a technically deep, hands-on engineer who thrives in early-stage development environments, can diagnose complex system-level issues, and can drive subsystems from concept through qualification and production readiness.

Requirements

• Bachelor’s degree or higher in Engineering (Mechanical, Electrical, Optical, Systems, Physics, or related field).
• Strong experience integrating complex electro‑optical systems or precision instrumentation.
• Demonstrated ability to debug system-level issues spanning optics, opto‑mechanics, electronics, firmware, and software.
• Experience developing system-level test methodologies and executing qualification testing.
• Hands-on experience with opto‑mechanical assemblies, precision alignment, and performance characterization.
• Ability to translate system requirements into subsystem specifications and test requirements.
• Strong technical documentation and communication skills.

Nice To Haves

• Experience with CRDS, laser spectroscopy, or other optical sensing / analytical instruments.
• Familiarity with embedded systems, firmware debugging, and data acquisition systems.
• Experience supporting alpha/beta builds and transitioning products from R&D into production.
• Background in environmental, reliability, or stress testing of precision instruments.
• Experience working in fast-paced prototype development environments.
• Successfully transitioned R&D test setups and processes into full-scale manufacturing environments.

Responsibilities

• Integrate optical, mechanical, electrical, firmware, and software components into complete CRDS analyzer systems.
• Develop and execute system-level test methodologies to evaluate performance, stability, reliability, and environmental robustness.
• Debug complex system-level issues and trace root causes across optical, mechanical, electrical, firmware, and software domains.
• Work closely with discipline experts to isolate failures, drive corrective actions, and validate fixes at the system level.
• Define system-level test strategies, test plans, and acceptance criteria for prototype, alpha, and beta builds.
• Design and implement test setups, automation, and data analysis methods to characterize system performance.
• Lead qualification testing for internal subsystems and full instruments, including performance, stress, and reliability testing.
• Document test results, failure modes, and design recommendations to support design iteration and production readiness.
• Lead programs to turnkey internal opto‑mechanical subassemblies from development into production-ready modules.
• Define subsystem-level specifications, interfaces, and test requirements aligned with system-level needs.
• Coordinate alpha and beta builds, manage build readiness, and drive closure of technical risks.
• Serve as the technical owner for assigned subsystems through qualification and handoff to manufacturing or sustaining teams.
• Support design-for-manufacturing (DFM), design-for-test (DFT), and design-for-reliability efforts during product transition.
• Collaborate with manufacturing, quality, and supply chain teams to ensure robust production test coverage and yield.
• Assist with production issue resolution by performing deep technical root cause analysis and corrective action validation.

Benefits

• Medical, Dental, and Vision insurance
• Flexible Spending Account (FSA) and Health Savings Account (HSA) plans
• Life, Short-Term Disability, and Long-Term Disability Insurance
• Paid Time Off and Paid Holidays
• Employee Referral Program
• 401K
• Social events (summer picnic, holiday party, team lunches, etc.)
• On-site Health & Wellness programs (fitness challenges, outdoor bootcamp, flu-shots, etc.)
