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
