Exosens Scientific is seeking a hands‑on Manufacturing Engineer to support electrical testing, troubleshooting, and manufacturing of Microchannel Plates (MCPs) and Channeltron detectors. This engineer will work directly on the factory floor in an ISO 7 cleanroom environment and is responsible for ensuring that detector assemblies meet electrical, vacuum, and performance specifications.

This role supports test station operation, performs full detector teardowns, helps maintain test capability during high priority manufacturing situations, and plays a key role in the transition from manual to more automated equipment. The ideal candidate is an engineer who enjoys practical, hardware‑centric work in a high‑voltage, high‑vacuum environment and is eager to learn specialized detector technologies. Because MCP/Channeltron expertise is rare, candidates from semiconductor, vacuum systems, photonics, electron optical components, or other high‑voltage industries are strongly encouraged.

This engineer ensures product quality by designing, developing, executing, and analyzing tests for software, focusing on high‑speed communication hardware, or physical goods, identifying defects, collaborating with development teams for fixes, and ensuring standards are met through detailed plans, test cases, and reports, often involving automation. Focus on functionality, reliability, safety, and performance across the product lifecycle.

This engineer is responsible for providing engineering and technical support to improve manufacturing yields, reducing scrap, and day‑to‑day production support for our Advanced Performance Detector (APD) production line. The APD is an assembly of several components like anode, phosphorus screen, time of flight detector (TOF), and a glass wafer composed of millions of micron‑sized channels with a bias angle. Within each channel electrons collide with the channel walls to generate more electrons which amplify the weak input signals.

APD’s have electrical properties suitable for Mass Spectrometry. The engineer provides support to manufacturing operations to ensure on‑time deliveries for all product lines.

• Perform electrical testing of MCPs and Channeltrons, including:
  • Operate and maintain high vacuum test systems (10⁻⁷ to 10⁻⁶ Torr)
  • Verify data integrity and elevate test anomalies promptly.

• Diagnose issues with MCPs, Channeltrons, and full detector assemblies.
• Perform full mechanical and electrical teardowns of detectors.
• Investigate failure modes such as low gain, electrical shorts, vacuum leaks, contamination, alignment issues, or component damage.

• Work daily with manufacturing operators in the cleanroom.
• Quickly respond to production issues when needed.
• Create or update work instructions, procedures, and test documentation.
• Assist in training operators and new engineers on testing and teardown methods.
• Completes assigned projects with overall goal of improving manufacturing yields and reducing scrap through process and product improvements.
• Tracks, analyzes, and reports yields, scraps, and defectives.
• Provides support in any or all product lines based upon need, including day‑to‑day support for the assigned product line production areas. Off‑shift work may be required at times.
• Collaborate with team to develop BOMs, routings, fixturing/tooling, and cost estimates of new products as well as updates to existing products and processes.
• Supports implementation of Lean Manufacturing, 5S, and SPC into manufacturing areas.
• Promotes and encourages understanding and use of the ISO 9001‑based Quality Management System.

• Use MINITAB intermittently for simple SPC, trend analysis, and yield monitoring.
• Support the transition from manual test stations to more automated equipment.
• Identify opportunities for improved test repeatability, data capture, and throughput.
