Mechanical Engineer III, Operations Engineering

Work Schedule Standard (Mon-Fri) Environmental Conditions Office Job Description As part of the Thermo Fisher Scientific team, you’ll discover meaningful work that makes a positive impact on a global scale. Join our colleagues in bringing our Mission to life every single day to enable our customers to make the world healthier, cleaner and safer. We provide our global teams with the resources needed to achieve individual career goals while helping to take science a step beyond by developing solutions for some of the world’s toughest challenges, like protecting the environment, making sure our food is safe or helping find cures for cancer. DESCRIPTION As a Mechanical Engineer III within Operations Engineering at Thermo Fisher Scientific, you will play a key role in the design, development, testing, and implementation of mechanical solutions for new and existing products. Working at the interface between Operations Engineering, R&D, Manufacturing, Quality, and external suppliers, you will transform technical requirements and engineering challenges into robust mechanical designs. You will develop and improve mechanical components, assemblies, mechanisms, and supporting systems , using engineering analysis, CAD design, prototyping, and hands-on testing to evaluate and optimize technical solutions. You will be involved throughout the engineering cycle, from initial concepts and feasibility studies through detailed design, prototype builds, verification testing, design improvements, and implementation into manufacturing. A significant part of the role will focus on testing and verification of mechanical designs . You will define test approaches, design test setups and fixtures, perform or coordinate engineering tests, analyze results, identify failure modes, and recommend design improvements. Your work will help ensure that mechanical solutions meet requirements for performance, reliability, robustness, safety, manufacturability, and serviceability. As a Mechanical Engineer III , you will also work closely with external suppliers and manufacturing partners on the development and optimization of mechanical parts and assemblies. You will provide technical requirements, review supplier designs and manufacturing proposals, resolve technical issues, and support prototype and pre-production builds. You will support the transfer of newly developed or modified mechanical designs into manufacturing, ensuring that solutions are robust, manufacturable, testable, and suitable for reliable production. Your combination of mechanical design expertise, practical testing experience, analytical thinking, and hands-on engineering approach will contribute to continuous product and technology development within Operations Engineering.
