About Hitachi, Ltd.
Through its Social Innovation Business (SIB) that brings together IT, OT (Operational Technology) and products, Hitachi aims to be a global leader in continuously transforming social infrastructure through digital, contributing to a harmonized society where the environment, wellbeing, and economic growth are in balance. Hitachi operates worldwide across four sectors – Digital Systems & Services, Energy, Mobility, and Connective Industries – as well as a Strategic SIB Business Unit focused on new growth areas.
With Lumada at its core, Hitachi creates value by combining data, technology and domain knowledge to solve customer and social challenges. Revenues for FY2025 (ended March 31, 2026) totaled 10,586.7 billion yen, with 606 consolidated subsidiaries and approximately 290,000 employees worldwide.
The Company
Applied Physics Technologies is a leading manufacturer of thermionic and field-emission cathodes and related electron-source assemblies. Located in the heart of Oregon's wine country, APT combines the global reach and resources of Hitachi High-Tech with the close-knit culture and individual impact of a smaller, growing manufacturing company.
Our products incorporate specialized materials, high-vacuum processes, precision manufacturing, high-voltage conditioning, and exacting assembly and test requirements. Because our engineering and production teams work closely together, Manufacturing Engineers at APT have a direct and visible impact on product quality, delivery performance, manufacturing capability, and customer satisfaction.
Summary:
As a Manufacturing Engineer, you will be responsible for the technical health, reliability, and continuous improvement of assigned manufacturing processes. You will work directly with production personnel to diagnose process and equipment problems, restore production when interruptions occur, reduce recurring failures, and improve manufacturing safety, quality, delivery, productivity, and cost.
APT's manufacturing processes include zone refining of boride materials and tungsten; micromachining and shaping of lanthanum hexaboride and cerium hexaboride crystals;
Schottky emitter assembly; cathode and electron-gun module assembly; tungsten etching; high-voltage conditioning; and cathode and module testing.
The successful candidate will develop sufficient knowledge of these processes to serve as a dependable technical resource when problems arise. This requires strong engineering fundamentals, hands-on mechanical and electrical aptitude, experience with vacuum systems and high voltage, disciplined troubleshooting skills, and the ability to work calmly but urgently during line-down situations.
A Manufacturing Engineer will also identify and implement process improvements, develop and maintain manufacturing documentation, support the company's Quality Management System, and help transfer new or modified products and processes into production.
Essential Responsibilities
Manufacturing Process Ownership
