Job description

Agency Robotics is pioneering the future of logistics by developing advanced robotic systems that optimize the movement of goods and make supply chains more human-friendly.

Founded by veterans of Boston’s leading robotics companies (Amazon Robotics, Motional, and 6 River Systems), we combine deep customer insight with cutting-edge mechatronics, intelligent software, and scalable hardware to transform warehouse operations. We’re passionate about simplifying complex processes through elegant automation—and putting agency back in the hands of the operator.

We’re seeking a Senior Mechanical Engineer to own the mechanical architecture of our flagship sorting solution and to lead the small team that builds it. This is a senior, hands-on role for an engineer who has taken electromechanical products from concept through volume production, and who wants to set the technical direction, standards, and pace for mechanical engineering as we scale.

As a Senior Mechanical Engineer, you will:

• Own the mechanical architecture of our sorting solution, including structures, mechanisms, mobile robots, and assembly tooling
• Lead a small team of mechanical engineers, including project management, design reviews, and mentorship
• Analyze design tradeoffs across performance, cost, durability, and manufacturability
• Design for real-world industrial use, considering loads, duty cycle, wear, ergonomics, safety, and serviceability
• Own the transition to production, including DFM/DFA and supplier selection
• Build and test prototypes, support production builds, and debug deployed systems
• Partner with electrical, controls, and software leads to define system interfaces
• Help grow the team through hiring, interviewing, and onboarding

• Expert proficiency in at least one 3D CAD platform (e.g., Onshape, SolidWorks)
• Skilled in rapid prototyping (e.g., 3D printing, machining, fabrication)
• Strong design process capabilities including drawing creation following GD&T, PLM administration, and BOM management
• Deep familiarity with production manufacturing processes (e.g., sheet metal, machining, weldments, injection molding, casting) and the tradeoffs
• Experience owning supplier and manufacturer relationships from RFQ through scale
• Strong process management skills for
• Experience integrating electromechanical components into mechanical designs
• Comfort and desire to use software tools (e.g., scripting, AI-assistants) to improve engineering workflows
• Excellent communication skills with the ability to document and present complex technical concepts
• Highly self-motivated and thrives in fast-paced, cross-functional startup environments
