Job Summary:
Under the direction of the Engineering Group Lead, the Senior Mechanical Engineer is a key technical leader responsible for the design, development, and delivery of custom, engineered‑to‑order industrial machinery. This role supports BCT’s mission of providing innovative, high‑performance custom equipment by translating customer requirements into robust mechanical solutions.

Beginning with the project kickoff, the Senior Mechanical Engineer leads mechanical design efforts including engineering calculations, 3D CAD modeling, and detailed machine layouts for complex custom assemblies. This position requires strong ownership of designs from concept through build, installation, and final performance, while collaborating closely with Applications Engineering, Controls, Manufacturing, Assembly, and Project Management.

Essential Duties and Responsibilities
This list of duties and responsibilities is not all-inclusive and may be expanded to include other duties and responsibilities as management may deem necessary from time to time.




Custom Machine Design & Engineering Leadership

• Serve as lead mechanical engineer on custom machine projects, collaborating with applications, manufacturing, assembly, and project management teams.
• Lead the conceptual development and detailed design of custom machinery, including mechanisms, frames, weldments, sheet metal, guarding, and system layouts.
• Apply sound mechanical engineering fundamentals and practical manufacturing knowledge (fabrication, welding, machining, assembly methods) to develop manufacturable, serviceable designs.
• Perform and review engineering calculations (loads, stresses, motions, tolerances, safety factors) to validate design performance and reliability.
• Own mechanical design intent and ensure consistency across models, drawings, and BOMs.
• Mentor and guide engineer I/II’s, providing leadership on design best practices, CAD standards, and problem‑solving approaches.
• Contribute to the development and maintenance of engineering standards, design guidelines, and reusable machine platforms

Project Execution

• Manage the mechanical engineering scope of assigned custom machine projects to meet cost, schedule, functionality, and quality objectives.
• Drive design reviews, risk assessments, and release milestones while maintaining alignment with customer requirements.
• Prepare and release complete engineering packages including 3D models, detailed drawings, bills of material, and supporting documentation.
• Communicate engineering status, technical risks, and design changes clearly to internal customers on a regular basis.
• Support continuous improvement by identifying opportunities to improve design efficiency, modularity, and manufacturability.

Cross‑Functional & Manufacturing Support

• Provide hands‑on support to Manufacturing by answering questions, resolving design issues, and issuing timely revisions.
• Collaborate closely with Electrical Engineering to ensure mechanical designs integrate seamlessly with automation systems (sensors, actuators, motion systems).
• Participate in or lead the creation of SOPs, standard machine elements, and common design libraries to streamline future custom projects.
• Partner with PMs to maintain schedule focus and support overall project execution.

Field & Customer Interaction

• Provide field support and occasional travel to assist with machine installation, commissioning, and troubleshooting.
• Participate in customer meetings and design reviews to present concepts, explain design decisions, and incorporate feedback into final solutions.
• Support root‑cause analysis and corrective actions for field issues or performance concerns.

Qualifications

• Strong expertise in SolidWorks or equivalent 3D CAD software for custom machine design.
• Proven ability to design engineered‑to‑order machinery that meets functional, budget, and schedule requirements.
• Experience designing mechanical systems that integrate with automation, motion control, and industrial controls.
• Excellent organizational skills with the ability to manage multiple priorities in a fast‑paced, project‑driven environment.
• Strong written and interpersonal communication skills with a collaborative, team‑oriented mindset.
• Proficiency with Microsoft Office; experience with project tracking tools such as MS Project or Smartsheet preferred.
