Summary of Position:

The Senior Mechanical Engineer leads mechanical design for automation and material-handling projects, integrating OEM conveyor systems, inspection and labeling subsystems, and custom mechanical solutions into complete, high-performance systems. This role develops mechanical architecture from concept through final drawing release, works closely with cross-functional engineering teams, and contributes to system performance, layout optimization, and innovative design approaches.

The ideal candidate is a strong mechanical designer and an active contributor who welcomes brainstorming, iteration, and concept development. This person helps create solutions that stand out in the market.

Essential Functions:

•    Lead mechanical design and integration of material-handling and automation subsystems.

•    Develop mechanical layouts, frames, guarding, mechanisms, and modular equipment interfaces

•    Design transitions between conveyors and other equipment and produce fabrication-ready drawings for these solutions.

•    Integrate subsystems from multiple vendors and ensure mechanical interfaces are correct and support cohesive system performance.

•    Translate system requirements into clear mechanical specifications for internal teams and external partners.

•    Understand throughput requirements and contribute mechanical solutions that improve flow and reduce bottlenecks.

•    Participate in concept development, brainstorming, early-stage modeling, layout iteration, and process refinement prior to final design.

•    Evaluate mechanical concepts and contribute improvements that make systems faster, smaller, stronger, more reliable, and easier to build.

•    Create fabrication-ready prints with correct tolerances, materials, and manufacturing notes.

•    Coordinate with fabrication partners to clarify design intent and support manufacturability.

•    Lead design and implementation of large-scale mechanical systems and automated equipment.

•    Architect mechanical layouts, frames, guarding, mechanisms, and modular platforms.

•    Perform advanced troubleshooting on complex or intermittent mechanical failures.

•    Develop mechanical design standards, best practices, and documentation requirements.

•    Train, mentor, and support engineers and technical staff.

•    Work with vendors, review proposals, and approve technical deliverables.

•    Ensure system reliability, manufacturability, and compliance with technical specification guidelines.

Work Environment:

This position is based in a professional office setting and regularly utilizes workplace technology, including computers, smartphones, multifunction printers, cloud-based filing systems, and collaboration tools.

Physical Demands:

 This role requires physical capabilities that support the successful execution of key responsibilities. The employee regularly engages in verbal and written communication with colleagues and clients to address project-related inquiries and must be able to convey accurate information clearly and efficiently. The position involves remaining seated at a workstation for approximately 75% of the time, with occasional movement throughout the office to access equipment, supplies, and shared resources. Daily tasks include consistent use of computers and standard office technology such as keyboards, printers, and multifunction devices. The role also involves transporting equipment boxes weighing up to 25 pounds within the building and to other offsite locations as needed for project support.

Required Education and Experience:

• Bachelor’s Degree in Mechanical Engineering or related field    
• 5-10 years of experience

Qualifications:

•    Bachelor’s degree in Mechanical Engineering or related field.

•    Strong communication, collaboration, and problem-solving skills.

•    Expert-level CAD (e.g., SolidWorks, Inventor, Onshape)  modeling and mechanical system design capability.

•    Strong understanding of process flow and automation equipment.

•    Basic understanding of how mechanical systems interface with automation controls, including sensor placement, camera mounting, field of view considerations, encoder usage, and motor-driven actuation.

•    Ability to evaluate system throughput, material flow, and performance and contribute ideas that improve overall efficiency.

•    Demonstrated ability to work with controls, software, and vision engineers to develop integrated and innovative system concepts.

•    Experience leading mechanical projects and supporting commissioning/startups.

•    Experience with release management with PDM/PLM tools (e.g., SolidWorks PDM, Windchill, Arena)  

•    Competence with engineering analysis tools (FEA, mechanism simulation, etc.).

•    Proven advanced troubleshooting and system optimization capability.

•    Ability to develop mechanical standards, best practices, and documentation.

•    Leadership, mentoring, and communication skills.
