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.
