Systems Integration Engineer

Job Title: Systems Integration Engineer Location: Santa Clara, CA (onsite) Group: Opto-Mechanical Engineering Role Summary 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. Roles and Responsibilities System Integration & Debug 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. Test Methodology & Validation 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. Subsystem Ownership & Program Leadership 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. Transition to Production 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. Required Qualifications 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. Preferred Qualifications 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. Salary & Benefits The base salary range for this full‑time position is $120000 to $130000.
