Senior Assembly Mechanical Engineer

Job Description:

• Develop and design manufacturing process workflows for ultra-clean product assembly in semiconductor and life science applications.


• Develop, transfer, and industrialize new manufacturing processes for the production of optical fiber assemblies and related products.


• Implement customer cleanliness requirements and cleanroom process specifications to ensure stable and repeatable production.


• Optimize assembly processes and manufacturing procedures to improve productivity, quality, efficiency, and cost.


• Lead continuous improvement initiatives and mentor team members to enhance assembly processes and operational excellence.


• Translate customer requirements into practical engineering solutions, design specifications, and detailed manufacturing documentation.


• Create conceptual and detailed engineering drawings, Bills of Materials (BOMs), routing, assembly instructions, and supporting documentation for prototype and production builds.


• Support prototype assembly, product validation, testing, and the transition from development to mass production.


• Conduct tolerance stack-up and GD&T analyses to ensure product manufacturability and compliance with design requirements.


• Review and maintain engineering documentation, including Engineering Change Notices (ECNs), engineering data packs, DFMEA, and other product lifecycle documents.


• Maintain accurate BOMs, routing information, and master data within the ERP/PLM system.


• Prepare, maintain, and update Standard Operating Procedures (SOPs), work instructions, and other technical documentation.


• Translate engineering drawings and technical documents from German to English (where applicable) and upload documentation into local systems.


• Support design reviews, technical discussions, project meetings, and risk assessments.


• Collaborate closely with R&D, Process Engineering, Production, Quality, Supply Chain, Sales, and Marketing teams to ensure successful product development and manufacturing.


• Ensure compliance with Environmental, Health & Safety (EHS) requirements and quality management systems, including ISO 9001, ISO 14001, ISO 13485, and AS9100D.


• Provide project documentation and administrative support for engineering and R&D activities as required.

Job Requirements:

• Bachelor's or Master's Degree in Mechanical Engineering or a related engineering discipline.


• At least 3–5 years of experience in mechanical engineering, manufacturing engineering, process engineering, or product development within the semiconductor, precision engineering, photonics, optics, or related manufacturing industries.


• Experience in optical fiber assembly or precision optics manufacturing is highly preferred.


• Experience in new product introduction (NPI), manufacturing process development, and process transfer to production.


• Hands-on experience in maintaining Bills of Materials (BOMs), routing, master data, and engineering documentation.


• Experience supporting prototype builds, product validation, testing, and production ramp-up.


• Knowledge of mechanical design principles, engineering drawings, GD&T, and tolerance stack-up analysis.


• Familiarity with 2D/3D CAD software and engineering document control practices.


• Understanding of Engineering Change Notices (ECNs), DFMEA, and product lifecycle documentation.


• Knowledge of contamination control and cleanroom manufacturing practices is an advantage.


• Ability to read and interpret engineering drawings; proficiency in translating technical documents from German to English is an added advantage.


• Strong analytical, organizational, and problem-solving skills with excellent attention to detail.


• Good communication and interpersonal skills, with the ability to work effectively in cross-functional and international teams.


• Self-motivated, proactive, and able to manage multiple priorities in a fast-paced manufacturing environment.


• Committed to continuous improvement and compliance with quality, environmental, and safety standards.
