Job summary

Activ Surgical is seeking a hands-on Mechanical Engineer to prototype and design mechanical systems and enclosures for real-time medical imaging and sensing devices. You will take concepts from early prototypes through to commercial-grade, manufacturable products while collaborating with electrical, optical, software, and clinical teams.

You should have a strong background in GD&T, rapid prototyping, and materials selection, with experience in 3D printing, sheet metal fabrication, and DFx

Qualifications

• BS, MS, or PhD in Mechanical Engineering or a related engineering discipline.
• Hand s‑on experience designing mechanical systems, enclosures, or housings for electro‑optical or medical devices
• Experience taking designs from concept through rapid prototyping to commercial‑grade, manufacturable products
• Proficiency with CAD software (e.g., SolidWorks) for 3D modeling, tolerancing, and drawing generation
• Demonstrated ability to conceptualize and rapidly prototype novel mechanical solutions using 3D printing, machining, and sheet metal fabrication
• Strong understanding of GD&T, DFM/DFA principles, and materials selection
• Strong communication skills and ability to collaborate closely with a cross‑functional team (electrical, optical, software, and clinical stakeholders)

Responsibilities

• Prototype and design mechanical systems and enclosures for real-time medical imaging and sensing devices.
• Bring concepts from early prototypes through to commercial-grade, manufacturable products.
• Collaborate with electrical, optical, software, and clinical stakeholders to optimize designs.
• Communicate designs clearly through drawings and 3D models.

Job description

Activ Surgical is building a platform for introducing the latest sensing technology to minimally invasive surgery, intended to visualize the invisible to facilitate better surgical decisions and outcomes. As part of the R&D team, you will be responsible for prototyping and designing novel mechanical systems and enclosures for real-time minimally invasive medical imaging and sensing devices, taking concepts from early prototypes through to commercial-grade, manufacturable products. You will be expected to bring a creative, detail-oriented, and dedicated approach to solving complex mechanical design challenges, stay current on the most pressing clinical and manufacturing constraints, and effectively communicate your designs with the broader cross-functional team.

Required Qualifications

• BS, MS, or PhD in Mechanical Engineering or a related engineering discipline
• Hands‑on experience designing mechanical systems, enclosures, or housings for electro‑optical or medical devices
• Experience taking designs from concept through rapid prototyping to commercial‑grade, manufacturable products
• Proficiency with CAD software (e.g., SolidWorks or equivalent) for 3D modeling, tolerancing, and drawing generation
• Demonstrated ability to conceptualize and rapidly prototype novel mechanical solutions using techniques such as 3D printing, machining, and sheet metal fabrication
• Strong understanding of GD&T, DFM/DFA principles, and materials selection
• Strong communication skills and ability to collaborate closely with a cross‑functional team (electrical, optical, software, and clinical stakeholders)

Preferred Qualifications

• Experience designing mechanical systems for medical devices, including familiarity with regulatory and design‑control requirements (e.g., FDA, ISO 13485)
• Experience with precision optomechanical assemblies or camera/sensor housing
• Background in thermal management, sealing/ingress protection, or sterilization‑compatible design
• Experience supporting design verification and validation (V&V) testing
• Familiarity with supply chain and vendor management for prototype and production builds
