We’re searching for a Senior Mechanical Design Engineer in Concord, Canada. This team focuses specifically on packaging, converting, and finishing equipment — machinery that performs printing, labeling, inspection, bank encoding, and end-of-line packaging. In this role, you’ll lead the conceptual design of custom automation systems, working alongside senior designers and cross-functional electrical, programming, vision, and motion-control teams to take machinery from concept through delivery on aggressive project timelines.
Responsibilities Lead the customized portions of machine design — generally the “mad scientist,” first-of-a-kind problem-solving work — while standard modules and components handle the rest
Develop and detail designs using SolidWorks (3D) and AutoCAD (2D), applying GD&T; principles throughout
Build and maintain bills of materials for both standard and custom-designed machine content
Work within SolidWorks PDM, leveraging the team’s library of standard modules alongside custom-designed elements
Collaborate closely with electrical, programming, vision, motion control, and application engineering teams to support the equipment’s PC-based, IP/Ethernet control architecture
Support fast-moving project timelines, from initial concept design through detailed design, integration, and final installation
Partner with field service and commissioning teams, incorporating feedback from onsite installation and troubleshooting to improve design and serviceability
Lead the conceptual design and development of custom high-speed automation systems built for speed, precision, and performance
Drive pure innovation and automation using advanced technologies




Work on cutting-edge engineering projects that truly challenge and excite you
Qualifications 5+ years of mechanical design experience in high-speed automation or custom machine building
Bachelor’s Degree in Mechanical Engineering or related discipline
Strong understanding of servo systems, pneumatics, mechanical motion systems, GD&T;, manufacturing and machining practices
Advanced proficiency in SolidWorks and experience with PDM/document control systems
Strong problem-solving mindset with a passion for innovation and technology
Comfortable working across both 3D and 2D CAD, including AutoCAD
Experience creating and maintaining bills of materials
Mechanical design experience involving moving machinery
Solid knowledge of conveyors, gear ratios, and power transmission, in addition to servos and pneumatics
Background in complex automation equipment design, rather than primarily automotive, mold-making, structural, or sheet metal design
Able to ramp up quickly and take ownership of designs against firm customer deadlines
Must be legally authorized to work in Canada
Preferred Qualifications Prior experience designing packaging, converting, or finishing equipment (printing, labeling, inspection, bank encoding, or end-of-line packaging systems)
Experience with PC-based control architectures using IP/Ethernet communication, rather than traditional PLC-based controls
Experience mentoring or pairing with intermediate-level designers
Comfortable providing remote engineering support to field service and commissioning teams
Schedule: 8:00am-4:30pm
Pay Rate Range: $140,000–$180,000/yr (DOE) CAD
