Mechanical Engineer

Sr Mechanical Engineer

The Sr Mechanical Engineer designs and develops innovative mechanical and electro-mechanical components and subsystems for industrial and commercial mobile cleaning robot platforms. This execution-focused role works within a cross-functional development team to deliver robust designs that meet performance, cost, and schedule requirements. The position combines hands-on mechanical engineering, new product development, and system-level thinking to bring advanced robotic solutions from concept through launch.

Responsibilities

• Design and develop mechanical and electro-mechanical product components and subsystems for industrial and commercial mobile cleaning robot platforms.
• Collaborate closely with cross-functional teams, including electrical, software, manufacturing, and supply chain, to ensure designs meet performance, cost, and schedule targets.
• Lead and execute new product development activities, from concept generation and feasibility studies through detailed design, prototyping, testing, and release to production.
• Create and maintain detailed 3D CAD models and engineering drawings using SolidWorks or similar CAD tools.
• Apply mechanical engineering principles to model, simulate, and predict system performance, ensuring that designs meet functional and reliability requirements.
• Perform tolerance analysis and apply GD&T to ensure manufacturability, fit, and function of components and assemblies.
• Develop and implement engineering standards, best practices, and design guidelines for mechanical and electro-mechanical systems.
• Conduct design reviews and present technical information and recommendations to internal and external stakeholders in a clear and compelling manner.
• Use data-driven methods, including statistical analysis and Six Sigma tools, to support design decisions and continuous improvement.
• Prepare and interpret technical documentation, including specifications, test plans, reports, and other engineering deliverables.
• Identify and mitigate risks through methods such as FMEA, ensuring robust and reliable product performance.
• Manage ambiguous design tasks as a self-starter, driving issues to resolution with minimal supervision.
• Support project management activities by providing accurate estimates, tracking progress, and helping to ensure projects stay on schedule and within budget.

Essential Skills

• Proven experience in mechanical design engineering, with four to eight years of relevant industry experience.
• Strong experience in the design and development of mechanical and computer-controlled electromechanical systems.
• Hands-on experience with new product development, including taking products from concept through production; new product development experience strongly preferred.
• Proficiency in CAD tools, with SolidWorks preferred, for creating 3D models and detailed engineering drawings.
• Demonstrated ability in creative and innovative problem solving for complex mechanical and electromechanical challenges.
• Self-starter mindset with the ability to manage ambiguous design tasks and drive them to completion.
• Strong analytical skills, including the ability to model and predict system performance based on engineering principles.
• Experience using data-based decision making and statistical analysis to support design choices.
• Proficiency in GD&T and tolerance analysis to ensure precise and manufacturable designs.
• Experience performing FMEA to identify and mitigate potential failure modes in designs.
• Strong written and verbal communication skills, with the ability to read, analyze, and interpret scientific and technical journals, financial reports, and legal documents.
• Ability to effectively present technical information to a variety of internal and external groups.
• Bachelor of Science in Engineering or equivalent degree from an ABET-accredited four-year college or university.

Additional Skills & Qualifications

• Master of Science in Engineering is preferred.
• Project leadership experience is preferred, including coordinating technical activities and guiding cross-functional efforts.
• Experience developing engineering standards and design guidelines for mechanical and electromechanical systems.
• Familiarity with Six Sigma methodologies and tools.
• Experience in industrial or commercial robotics, automation, or mobile platforms is beneficial.
• Experience with sheet metal design and drafting is advantageous.
• Exposure to project management practices, including planning, tracking, and reporting, is helpful.
