Mechanical Design Engineer

Senior Mechanical Design Engineer Job Description This role offers an opportunity for an experienced Senior Mechanical Engineer to lead the design, development, integration, testing, and qualification of complex mechanical systems that support human spaceflight and space exploration programs. The position focuses on advanced product development within high-technology industries such as aerospace, spacecraft, transportation, and robotics. You will apply deep mechanical design expertise across the full product lifecycle, from concept through production, while collaborating closely with multidisciplinary engineering teams to deliver robust, high-performance hardware for next-generation station-side systems. Responsibilities

- Lead the end-to-end design and development of complex mechanical systems, mechanisms, and mechatronic hardware for human spaceflight and space exploration applications.
- Drive product development activities from initial concept through detailed design, prototyping, testing, qualification, and transition to production.
- Develop, decompose, and manage engineering requirements, ensuring that mechanical designs meet performance, reliability, safety, and regulatory expectations.
- Plan and execute risk mitigation activities, including design reviews, trade studies, and failure mode and effects analyses (FMEA/DFMEA).
- Create, review, and maintain detailed 3D CAD models and engineering drawings using SOLIDWORKS or equivalent tools, ensuring adherence to ASME Y14.5 GD&T standards.
- Perform or oversee structural, thermal, and dynamic analyses using finite element analysis (FEA) tools such as ANSYS and Nastran, and support modeling and simulation using MATLAB and Simulink.
- Apply Design for Manufacturing (DFM) and Design for Assembly (DFA) principles to optimize designs for producibility, cost, and reliability.
- Define and support qualification testing and acceptance testing plans, ensuring that hardware meets all verification and validation requirements.
- Collaborate closely with cross-functional teams, including systems, electrical, software, manufacturing, and test engineering, to integrate mechanical designs into complex hardware systems.
- Provide technical leadership and mentorship to engineering team members, fostering best practices in mechanical design, analysis, and documentation.
- Support functional management responsibilities by contributing to planning, resource allocation, and technical decision-making in a highly regulated engineering environment.
- Ensure compliance with relevant aerospace and spaceflight standards, including NASA standards and verification processes where applicable.
- Troubleshoot and resolve complex engineering issues, exercising sound judgment to drive timely, effective solutions in a fast-paced development environment.
- Coordinate with stakeholders to support program milestones, design reviews, and customer or regulatory audits related to mechanical systems.

Essential Skills

- Minimum of 8 years of experience as a Mechanical Design Engineer or Mechanical Engineer in aerospace, spacecraft, automotive, robotics, oil and gas, transportation, or related high-technology industries.
- Extensive experience in mechanical design with emphasis on mechanisms, mechatronic systems, and motion-control hardware.
- Proficiency with 3D CAD software, including at least 8 years of experience using SOLIDWORKS or equivalent modeling platforms.
- Demonstrated ability to create, interpret, and review engineering drawings with geometric dimensioning and tolerancing (GD&T) in accordance with ASME Y14.5 standards.
- Experience utilizing finite element analysis (FEA) tools such as ANSYS and Nastran for structural, thermal, and dynamic analysis.
- Proficiency with MATLAB and Simulink for engineering analysis, modeling, and simulation.
- Strong foundation in statics, dynamics, structural analysis, fracture control, fatigue, thermal effects, materials engineering, and lubrication systems.
- Proven experience leading product development efforts from concept through production, including requirements development, risk mitigation, verification, validation, and system qualification.
- Strong understanding and practical application of Design for Manufacturing (DFM) and Design for Assembly (DFA) principles, as well as qualification and acceptance testing methodologies.
- Demonstrated ability to provide technical leadership and mentor engineering teams in a multidisciplinary environment.
- Experience supporting the design, development, and integration of complex hardware systems in highly regulated engineering environments.
- Bachelors degree in Mechanical Engineering, Aerospace Engineering, or a related engineering discipline.

Additional Skills & Qualifications
