Mechanical Engineer

Harton • Cambridge, MA

5d

About The Position

Harton is seeking a highly motivated Mechanical Engineer with 4–7 years of experience in mechanical design to contribute to the development of its novel bioprocessing platform. The role supports planning, design, prototyping, integration, and testing of complex electromechanical subsystems, working closely with small multidisciplinary science and engineering teams throughout the development process.

The ideal candidate brings strong mechanical design intuition, hands-on experience with electromechanical systems, and enthusiasm for developing technologies that enable the manufacturing of next-generation cell-based products.

Requirements

• BS or MS in mechanical engineering, mechatronics, or a related field, with approximately 4–7 years of experience in complex electromechanical product development.
• High proficiency in 3D CAD and experience collaborating on a hardware product. Harton uses Onshape for 3D CAD.
• Proficiency using AI tools to support routine engineering tasks.
• Experience with rapid prototyping, low- and high-volume manufacturing technologies, and domestic and international supplier relations.
• Excellent communication skills and the ability to explain engineering concepts and workflows to non-engineering colleagues and commercial teams.
• Excellent engineering judgment and the ability to independently evaluate technical trade-offs, cost, risk, and schedule when making decisions.

Nice To Haves

• Experience in electronics design and assembly, actuators, motion control, and sensors; hobby, industrial, and robust theoretical experience are acceptable.
• Proficiency in EDA software, signal analysis, and communication protocols.
• A portfolio illustrating the design and fabrication of personal projects that may highlight technical problem solving, diverse interests or experiences, and the ability to document and share complex work. Candidates should include a portfolio link in their resume.
• Familiarity with thermal and fluid flow simulation as applied to mechanical system design.
• Understanding of cell expansion and fundamental bioprocessing concepts.
• Familiarity with the U.S. technology patent process.
• Experience in optics, microscopy, fluidics, materials science, or the practical intersections of these disciplines.

Responsibilities

• Support the design, prototyping, integration, and qualification of automated cell growth and characterization instruments with cross-functional engineering and biology teams.
• Design, prototype, and test electromechanical subsystems against technical and performance requirements, from concept through release.
• Propose and execute data-driven improvements based on instrument performance and validation testing.
• Manage relationships with domestic and international suppliers for custom and off-the-shelf components.
• Participate in project planning and scheduling under the direction of technical team leads.

Benefits

• Comprehensive medical coverage.
• Company-funded Health Savings Account (HSA) for eligible medical, vision, and dental expenses.
• Wellness incentives and health club reimbursement.
• Mental health resources and telehealth access.
• Paid parental, family, and medical leave.
• Financial wellness education resources.
• Flexible vacation and sick time.
• 12 paid holidays plus an annual winter break.
