Internship Injection Molding Engineer Jobs in Spring, TX

We are seeking a highly skilled and technically strong Principal Mechanical Engineer to lead mechanical architecture and design for our Actuator product lines. This role requires deep expertise in drive train and gear design, mechanical power transmission, housing and enclosure development, and precision fabrication. You will serve as the technical authority for actuator mechanical systems, driving the design of gears, clutches, housings, sealing systems, and motion components while ensuring structural integrity, reliability, and manufacturability.
As a senior technical leader, you will guide end-to-end mechanical development-from concept through prototyping, analysis, qualification, and launch-while collaborating closely with electrical, controls, firmware, and systems engineering teams. You will also lead design reviews, drive DFM and cost optimization, engage with suppliers, and support lifecycle management and root cause investigations. This role is critical to advancing our actuator platforms and delivering robust, compliant, and high-performance mechanical solutions.
Job Responsibilities:

• Lead actuator mechanical architecture including gears, clutches, housings, sealing systems, and precision motion components.
• Design and integrate complex mechanical assemblies such as gear trains, motors, torque transfer mechanisms, and injection-molded parts.
• Perform structural and thermal analysis using FEA to validate integrity under static, dynamic, fatigue, and thermal loads.
• Drive reliability engineering through load path analysis, stress evaluation, wear modeling, and fatigue life prediction.
• Develop actuator enclosures with consideration for hazardous location requirements, structural integrity, thermal management, EMI shielding, and environmental protection.
• Select materials and manufacturing processes including casting, machining, molding, and advanced coatings.
• Collaborate cross-functionally with electrical, controls, firmware, and systems engineering teams to ensure integration of motors, electronics, sensing mechanisms, control systems, and user interfaces with mechanical systems and housing.
• Lead design reviews and contribute to validation, qualification, and verification activities.
• Maintain engineering documentation including BOMs, specifications, test plans, and ECOs.
• Drive DFM and cost optimization across actuator components and assemblies.
• Engage with suppliers to resolve fabrication issues and ensure quality standards.
• Manage component lifecycles including obsolescence planning and alternate sourcing.
• Lead root cause analysis and corrective actions for mechanical failures or field issues.
• Ensure compliance with global regulatory and industry standards including hazardous locations (UL, CE, ATEX, IEC, RoHS, REACH).
• Provide end-to-end mechanical leadership from concept through prototyping, testing, qualification, and launch.
• Coordinate global engineering teams and collaborate closely with electronics, firmware, and software leaders.

Who you are:
You scan the environment for new technical skills, knowledge, or capabilities that can benefit business or personal performance. You create competitive and breakthrough strategies that show a clear connection between vision and action. You use knowledge of business drivers and how strategies and tactics play out in the market to guide actions.
Required Education, Experience, & Skills:

• Master's degree in Mechanical Engineering (or related discipline) with 8+ years of mechanical or electromechanical product engineering experience OR Bachelor's degree in Mechanical Engineering (or related discipline) with 10+ years of relevant engineering experience.
• Deep experience with industrial equipment including drive trains, gears, housings, sealing systems, and mechanical power transmission.
• Strong background in motor-driven systems, motion control, and integration of mechanical and electrical subsystems.
• Proficiency in advanced CAD modeling and design of machined, cast, and molded components.
• Experience performing structural analysis and FEA, including static, dynamic, fatigue, and thermal evaluations.
• Expertise in formal design processes, including DFMEA, PFMEA, DFM, DFA, design reviews, and structured engineering documentation.
• Demonstrated leadership across the full product lifecycle, from concept through prototyping, testing, qualification, and launch.
• Experience working with cross-functional engineering teams, including electrical, controls, firmware, systems, manufacturing, and suppliers.
• Strong communication, documentation, and technical leadership skills, with the ability to mentor and guide engineering teams

Preferred Education, Experience, & Skills:

• Background in actuator-specific technologies, including sealing systems, environmental protection, and long-life reliability engineering.
• Experience designing and certifying products for use in hazardous locations (FM, ATEX, IECEx, etc)
• Experience with global regulatory and industry standards (ISO 22153, API6DX, RoHS, REACH).
• Experience with castings (sand, investment, high pressure die)
• Familiarity with industrial networking, motor-control systems, and electromechanical integration.
• Experience leading global or multi-site engineering teams and coordinating complex development programs.
• Six Sigma certification (Green Belt or Black Belt) or equivalent process-improvement training.
