OUR MISSION

To tackle the growing e-waste problem, Molg enables circular manufacturing with robotics and design. Its robotic microfactories can autonomously disassemble complex electronic products, and the team partners with leading manufacturers to design electronics with reuse in mind — ensuring one product’s end is another’s new beginning.

Molg combines advanced robotics and intelligent software to transform how electronics are manufactured and recovered. Working with partners like HP, leading hyperscalers, and industrial companies such as ABB and Stanley Black & Decker, Molg’s solutions recover valuable materials from existing devices while helping create the next generation of products optimized for circularity. This dual focus on recovery and design innovation drives Molg’s mission to keep materials in use and reduce waste.

IN THIS ROLE YOU WILL

Join a cross-functional team of software, electrical, robotics, and operations engineers to design, develop, and validate the articulating end of arm tooling (EOAT) that powers our robotic microfactory. This is hands-on, mechanism-forward work — multi-DOF grippers, compliant linkages, actuated fingers, force-controlled contact systems, and tooling that must adapt to real variability in device geometry and assembly state. As the Mechanical Engineering Lead, you will own the full design cycle from concept through production validation and lead a small team of mechanical engineers doing the same.

Design & Engineering

• Lead the design and development of end of arm tooling — grippers, fixtures, and compliance mechanisms — for automated electronics disassembly.

• Define tooling requirements in collaboration with robotics, automation, and operations teams.

• Perform mechanical analysis (stress, tolerance, kinematic) to validate designs before fabrication.

• Oversee prototyping, testing, and iterative refinement of EOAT systems.

• Ensure designs meet reliability, repeatability, and cycle-time targets in production environments.

• Apply DFM principles to minimize cost and lead time.

Technical Leadership

• Serve as Technical Lead Manager for a small team of mechanical engineers — assign tasks, set milestones, and track deliverables across the EOAT workstream.

• Conduct design reviews, provide technical feedback, and maintain quality standards across the team's output.

• Mentor junior and mid-level engineers, supporting their technical growth and career development.

• Act as the primary technical point of contact for EOAT within the project team.

Cross-Functional Collaboration

• Partner with robotics, software, and manufacturing teams to integrate EOAT into the broader automated disassembly system.

• Communicate design status, risks, and dependencies to project leads and stakeholders.

• Contribute to project planning with realistic engineering estimates and technical input.

• Help resolve integration issues and unblock teams during implementation phases.

Process & Documentation

• Maintain design documentation, BOMs, drawings, and revision history to engineering standards.

• Establish best practices for EOAT design, testing protocols, and knowledge sharing within the team.

• Support lessons-learned processes to continuously improve tooling reliability and development speed.

WHO YOU ARE

A hands-on mechanical engineer with deep expertise in kinematic design, mechanism synthesis, and actuation systems — and the technical leadership to drive execution in a fast-paced, hardware-intensive environment. You take full ownership of your workstream and know how to bring a team along with you. Specifically, you have:

• Bachelor's degree in Mechanical Engineering or related field (Master's a plus).

• 5–8 years of experience in mechanical design, with at least 2 years in a technical lead or team lead capacity.

• Hands-on experience designing articulating mechanisms — grippers, compliant linkages, actuated systems, or similar.

• Proficiency in CAD tools (SolidWorks, Fusion, or equivalent) and engineering analysis methods.

• Experience with DFM and mechanical testing and validation processes.

• Familiarity with automation systems, robotics integration, or microfactory environments is strongly preferred.

• Strong communication skills and experience working in cross-functional product or project teams.

WHO WE ARE

We spend our days building robotic systems, developing complex assembly intelligence software, and designing the next generation of circular products for our customers. Given the importance of working hands-on with physical systems, we are a 100% in-person team collaboratively working in our industrial space in Sterling, VA, down the road from the largest data center market in the world. Our facility includes a variety of robots, CNC milling machines, 3D printers, and all the tools needed to build and test our products. It is important to us that anyone on our team that is interested in learning how to use our various pieces of equipment and machinery is taught and can gain the skills and appreciation for making physical things.

THING TO KNOW

• We're a hands-on, collaborative team with big ambitions — expect full ownership and meaningful technical challenge from day one.

• There's a good amount of context-switching. We expect people to be autonomous and drive their own work to completion.

• This role grows with the company. As the microfactory program scales, there is a clear path to expanded team leadership and the opportunity to grow into a principal-level technical contributor.

• We're scrappy and building a great, sustainable company for years to come. Priorities may shift as the business evolves — we give people the context and decision-making power to meet that head on.
