Merista builds the physical AI workforce for food production. This is our founding team hardware hire, reporting to the CTO, owning the robot’s body that we can build repeatedly, clean, maintain, and operate on a factory floor. Full-time and on-site in Barcelona.

The robot has to handle it accurately, meet the pace of the line, and work in cold, wet environments where cleaning is part of daily operation.
How do we protect components from moisture and cleaning chemicals while managing heat inside sealed enclosures?
How do we turn a working prototype into robots that are straightforward to assemble, service, and repair within a tight cost target?

You’ll lead hardware design choices and define interfaces with the engineers responsible for perception, learning, and control. Structure and mobile base: stiffness, levelling, component layout, and access for maintenance.
Sensing and weighing integration: working with robotics engineers to make measurement and manipulation reliable.
Components, suppliers, and cost:



owning the bill of materials and making explicit tradeoffs between performance, reliability, and build cost.
Build and validation: prototypes, test rigs, assembly jigs, failure investigation, and a repeatable build process for a small fleet.

Experience taking mechatronics devices from design through build, testing, and production use.
Hands-on prototyping and debugging: you can move between CAD, the workshop, and a failing machine.
Willingness to work across mechanical, electrical, sensing, and software boundaries.
We’re interested in the decisions you made, including what you simplified, what you tested, and which tradeoffs you accepted.

Most meals in the developed world pass through a food factory. Factories cannot keep those rooms staffed.
Merista builds the physical AI workforce for food production: operated robots that take over these tasks. One robot rolls onto a factory floor without rebuilding the line. We deploy it and run it, and the factory pays for
