Mechatronics Engineer

About Enact

The next defining technological breakthrough will be in the physical world. We stand at a historical inflection point: bringing general-purpose intelligence into robotics.

At Enact we rethink the entire robotic tech stack from model architectures and data pipelines, to the actuators and sensors that feed the model. Pushing beyond pure vision and language approaches, we build a proprioceptive nerve system, and the cortex that makes sense of it, to solve dexterity through whole-body force-awareness and deploy robots for thousands of tasks in industry and beyond.

We are shaping a company where brilliant and unconventional people thrive together on solving the hardest challenges of our time. We are truth seekers. We reason from first principles, test our beliefs against reality, and trust that the best ideas can come from anyone. We move fast. We care deeply about our work and colleagues and are driven by passion to change the status quo.

If this resonates, we're excited to hear from you.

In This Role You Will

• Design mechatronic systems for robotic manipulation: structural components, linkage mechanisms, actuators, and cable/sensor integration

• Own development end-to-end — from concept and system architecture through prototyping, testing, and series production

• Rapid-prototype new concepts to validate ideas quickly, then rigorously analyze (FEM, tolerance stack) and test in to lab to bring them to production quality

• Collaborate closely with manufacturing partners and internal electronics, controls, product, and deployment teams

What We're Looking For

• Degree (BSc/MSc/PhD) in mechanical engineering or related field

• 3+ years working experience designing and developing complex mechatronic systems

• Strong CAD skills (e.g., OnShape) and PDM experience

• Hands-on with rapid prototyping (3D printing, laser cutting), workshop tools, and prototype assembly/testing

• Solid grasp of common manufacturing methods such as CNC machining, sheet metal, 3D printing, tooled parts (e.g., injection molding), and precision assembly

• Curiosity to interface and collaborate with adjacent areas: electronics, software/firmware, robot control, teleoperation

• Fluency in English (spoken and written), with strong interpersonal and communication skills.
  

Bonus Points If You Have

• Hands-on development experience of high DoF robotic systems (e.g., robotic arms, end-effectors, humanoids)

• Development experience of actuator systems (frameless motor, gearbox, housing)

• Experience in the design and integration of electronic PCBs and cable-harnesses

• Thermal management and cooling system design
  

What we offer

• The opportunity to make a real impact working on some of the biggest challenges of our time

• A fast-paced learning environment alongside an outstanding, driven team

• Ownership from day one, with the ability to iterate quickly and see your impact firsthand in an early-stage startup

• Visa sponsorship & relocation benefits to hire the best in the world

• A world-class in-person setup in central Zürich, with excellent prototyping, robotics, and technical infrastructure for hands-on builders

• Competitive compensation and meaningful equity participation
