Senior Tech: Electromechanical & Catheters

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…
