Manufacturing Engineer Technician II (2nd Shift)

At Nextern, we inspire with passion, impact with significance, and act with integrity.. Nextern partners with OEMs, clinicians, and innovators to design, develop, and manufacture world-class medical devices across the full product lifecycle. From single-use disposables to fully integrated systems to precision components, our teams work as an extension of yours to solve patient needs and improve lives worldwide.

Nextern is seeking a versatile, hands-on Manufacturing Engineering Technician who can work across both sides of our product portfolio: complex electromechanical devices — consoles, capital equipment, and their supporting test systems — and precision single-use disposables, specifically catheter and balloon catheter systems. This combined role exists because our programs increasingly pair a capital console with a disposable, and we need technicians who can support the full system rather than one half of it.

The technician serves as a direct extension of the manufacturing engineering team on the floor and is often the first person to touch a problem.

2nd shift hours - Monday through Thursday - 1:30pm to 12:00am

Responsibilities:

• Build, integrate, and debug consoles, capital equipment, and complex electromechanical assemblies — including enclosures, power supplies, motion and pneumatic subsystems, wire harnesses, and cable assemblies — working from large multi-level bills of material and multi-operation routings.
• Handle, install, and troubleshoot printed circuit board assemblies (PCBAs) and electronic subassemblies; perform and inspect solder and rework operations to IPC-A-610 and J-STD-001 workmanship criteria; build and inspect cable and harness assemblies per IPC/WHMA-A-620; maintain ESD controls per ANSI/ESD S20.20.
• Execute firmware loading, device programming, configuration, and serialization steps at the station level, and verify results against the traveler and device history record.
• Support first-article, prototype, and pilot builds; capture build issues, cycle times, and process feedback for engineering; assist in refining work instructions before production release.
• Set up, operate, and troubleshoot electrical safety test stations — dielectric withstand (HIPOT), insulation resistance, ground bond / protective earth continuity, and leakage current — following defined parameters and safety controls, and escalating failures with clear technical documentation.
• Operate, maintain, and debug automated test equipment (ATE), functional test stands, and end-of-line test systems; diagnose fixture, cabling, instrumentation, and unit-under-test failure modes; support test station replication, setup, and periodic verification.
• Use multimeters, oscilloscopes, power supplies, and data acquisition equipment to isolate faults down to the component, connector, or subassembly level; read and work from electrical schematics, wiring diagrams, and interconnect drawings.
• Perform catheter shaft preparation including cutting, grinding, skiving, and surface treatment; execute tip forming operations using heat forming equipment; apply radiopaque marker bands using precision placement fixtures and bonding techniques; support extrusion operations for multi-lumen tubing.
• Perform balloon bonding (proximal and distal), folding, and wrapping using manual and semi-automated equipment; inspect balloons for pinholes, wrinkles, and dimensional nonconformance.
• Assemble complete catheter systems including hubs, strain reliefs, guidewire lumens, hemostasis valves, and Luer fittings using adhesive bonding, thermal bonding, and mechanical crimping operations.
• Conduct burst pressure and rated burst pressure verification, leak testing, compliance testing, and tensile and bond strength testing using pull testers; document all results in batch records and ERP.
• Execute Installation Qualification (IQ) and Operational Qualification (OQ) protocols on new and existing manufacturing and test equipment; document results meticulously and compile clear reports for engineering review.
• Perform routine preventive maintenance on assembly, test, and catheter processing equipment; manage calibration schedules for measurement and test equipment; coordinate repairs with maintenance, engineering, and vendors.
• Perform in-process and final dimensional inspection using calipers, micrometers, optical comparators, and microscopes; conduct visual inspection under magnification against defined acceptance criteria.
• Manage the returned product process — receiving, decontamination, functional and physical evaluation, and initial investigation — and provide precise, well-documented findings to Quality and Engineering to support complaint investigations and product improvement.
• Use Epicor ERP for work order processing, material transactions, labor reporting, inventory management, and BOM and routing verification against the physical build.
• Complete device history records, travelers, batch records, and test data accurately and legibly; draft and red-line work instructions and procedures for engineering review; support deviation and nonconformance investigations and corrective actions.
• Work in full compliance with FDA 21 CFR Part 820, ISO 13485, and cGMP requirements, including DHF and DMR expectations.
• Maintain and operate equipment within Class 7/8 cleanroom environments, adhering strictly to gowning, cleaning, and contamination control procedures; monitor and document environmental conditions.
• Partner with engineers to identify process improvements, fixture and tooling enhancements, error-proofing opportunities, yield gains, and cycle time reductions; build and modify simple fixtures as directed.
• Train and support operators and newer technicians on assembly, test, and catheter processes; serve as a floor-level technical resource across both product families.
• Potential travel to international manufacturing sites (Costa Rica, China, Vietnam).

Requirements

• Required: High school diploma or GED required.
• 5+ years of hands-on technician experience in medical device or comparably regulated manufacturing. This is not an entry-level position.
• Demonstrated depth in at least one of the two core domains — (a) electromechanical / capital equipment build and test, or (b) catheter and balloon manufacturing — with working proficiency and clear aptitude in the other.
• Hands-on experience executing equipment qualifications (IQ/OQ) and writing clear technical reports.
• Proven experience troubleshooting to root cause using both hand tools and electronic test equipment.
• Prior experience working in a Class 7/8 cleanroom environment.
• Working knowledge of Epicor or a similar ERP / manufacturing execution system.
• Strong working understanding of FDA 21 CFR Part 820 Quality System Regulation and cGMP requirements.
• Familiarity with ISO 13485 Medical Device Quality Management System.
• Understanding of Design History File (DHF) and Device Master Record (DMR) requirements.
• Awareness of IEC 60601-1 electrical safety requirements as they drive production test, and ISO 10993 biocompatibility requirements for patient-contacting materials.
• Ability to read and work from electrical schematics, wiring and harness diagrams, interconnect drawings, and mechanical prints.
• Proficiency with electronic test and measurement equipment: multimeters, oscilloscopes, power supplies, HIPOT testers, and data acquisition systems.
• Soldering, rework, crimping, and cable and harness build skills to recognized workmanship standards.
• Understanding of ESD control requirements and proper handling of electronic assemblies.
• Comfort navigating large, multi-level BOMs and multi-operation routings and identifying discrepancies between documentation and the physical build.
