Position Summary
Exosens Scientific is seeking a hands-on Manufacturing Engineer to support electrical testing, troubleshooting, and manufacturing of Microchannel Plates (MCPs) and Channeltron detectors. This role operates directly on the factory floor within an ISO 7 cleanroom and ensures detector assemblies meet electrical, vacuum, and performance specifications.
The ideal candidate is a hardware-focused engineer who enjoys working with high-voltage, high-vacuum systems and is comfortable in a highly technical, hands-on environment. This position plays a key role in sustaining production, improving yield, and supporting the transition from manual to semi-automated test systems.
Candidates with backgrounds in semiconductors, vacuum systems, photonics, electron optics, or similar high-voltage technologies are strongly encouraged to apply.
Key Responsibilities
Electrical Testing & Data Integrity
- Perform electrical testing of MCPs and Channeltron detectors
- Operate and maintain high-vacuum systems (10⁻⁷ to 10⁻⁶ Torr)
- Ensure data accuracy and escalate anomalies as needed
Troubleshooting & Failure Analysis
- Diagnose issues in detector assemblies (electrical and mechanical)
- Perform full teardown and root cause analysis
- Investigate failures such as low gain, shorts, vacuum leaks, contamination, and misalignment
Manufacturing Support
- Partner closely with cleanroom operators on daily production activities
- Provide rapid response to production issues
- Develop and update work instructions, SOPs, and test documentation
- Train operators and engineers on testing and teardown procedures
- Drive yield improvement and scrap reduction initiatives
Process Improvement & Quality
- Track and analyze yield, scrap, and defect trends
- Utilize tools such as MINITAB for SPC and trend analysis
- Support implementation of Lean Manufacturing, 5S, and SPC
- Promote adherence to ISO 9001 Quality Management System
Equipment & Test Systems
- Maintain and configure test equipment (high-voltage power supplies, vacuum systems, electrometers, oscilloscopes)
- Support test fixture setup and modifications
- Assist with transition to automated testing solutions
Cross-Functional Collaboration
- Support BOM development, routings, tooling, and cost estimates
- Provide engineering support across multiple product lines
- Ensure on-time delivery of production outputs
Required Qualifications
- U.S. Citizenship (required due to ITAR regulations)
- Bachelor’s degree in Electrical, Mechanical, Materials, Physics, or related engineering field
- Hands-on experience with high voltage, vacuum systems, precision instrumentation, or cleanroom environments
- Strong troubleshooting skills in electrical and mechanical systems
- Solid mechanical aptitude and willingness to work directly with hardware
- Proficiency with Microsoft Office and general engineering software tools
Preferred Qualifications
- Experience in semiconductor, photonics, vacuum systems, or electron optics industries
- Familiarity with SPC tools (e.g., MINITAB)
- Experience with high-voltage power supplies, turbopumps, vacuum chambers, or electrometers
- Background in assembling/disassembling delicate electro-mechanical systems
- Understanding of electron-multiplying devices (e.g., MCPs, PMTs, avalanche detectors)
Work Environment
- 100% on-site in an ISO 7 cleanroom (gowning required)
- Exposure to high-voltage and high-vacuum equipment (training provided)
- Day shift with occasional off-shift support for critical production needs
- Use of PPE including gloves, safety glasses, and hearing protection
Additional Details
- Experience Level: 5–10+ years preferred
- Highly hands-on role with custom-built equipment (training provided)
Ideal Candidate Profile
- Background in electro-mechanical systems, vacuum environments, and test engineering
- Strong experience in failure analysis, troubleshooting, and production support
- Comfortable working on custom equipment in a manufacturing setting
