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,…
