Support Engineer, Mechatronics

Tactus AI is building the first humanoid mobile manipulators purpose-built for clinical and life sciences laboratories. Our robots don't just move samples between instruments - they stain slides, check microbiology plates, load tissue processors, and perform the hands-on work that keeps labs running. Paired with CORTEX, our intelligent lab orchestration platform, they turn fragmented manual workflows into continuous, traceable automation.

Scientists are doing critical work, and patients are counting on them. We're a team of scientists, engineers, and operators in San Diego who believe labs deserve better. We move with the speed and focus that mission demands. We build with modern tools - LLMs and generative AI are part of our daily workflow, not a slide deck aspiration. We're shipping robots into real partner labs, backed by partnerships with leading diagnostics and life sciences organizations.

As our fleet grows, so does this team. Mechatronics support engineers deploy and maintain every robot we ship. When something physical doesn't work, this team figures out why and fixes it. When a robot needs to be ready for a partner site, this team makes sure it's solid before it leaves the building.

The work is physical, varied, and directly connected to whether our robots work in the real world. One week you might be chasing down an intermittent power issue and rebuilding a cable harness. The next you're at a partner lab setting up a robot, validating performance, and troubleshooting on-site.

You'll work alongside our production team, mechatronics engineers, and applications scientists. AI tools help with code — what they can't do is crimp a connector, trace a wiring problem, or build a fixture that holds tolerance.

What you'll do:

• Deploy and maintain robot systems — get things working, figure out what breaks, make them more reliable

• Diagnose and fix hardware problems — trace wiring issues, identify failing components, repair or replace

• Create test fixtures, jigs, and tooling as the team needs them

• Travel to partner sites to install robots, validate performance, and troubleshoot on-site

• Keep the lab and robot fleet operational so the engineering team can iterate without waiting

• Feed reliability insights back to engineering — what breaks, why, and how to prevent it next time

• Contribute to deployment documentation alongside the team — so every deployment gets smoother than the last

• Hands-on experience with electromechanical systems — robotics, automation, medical devices, aerospace, or similar. We care more about what you've built than where you studied.

• You can troubleshoot — read a schematic, pick up a multimeter, and find the problem

• Comfortable building things — hand tools, 3D-printed parts, cable harnesses, connectors, fasteners

• Self-directed — you can show up at a partner site with a robot and come back with a working deployment

• Comfortable with travel (20-40%, primarily to partner labs)

• Experience with mobile robots, articulated arms, or humanoid systems

• PCB rework and board-level troubleshooting

• 3D printing and rapid prototyping

• Experience in field service or production for lab equipment or medical devices

• Build what matters. Nothing ships or deploys unless the robot physically works. Your hands-on work is directly connected to patient outcomes in real partner labs.

• Move with urgency. One day you're building a cable harness, the next you're setting up a robot at a partner lab. The pace is fast and the work is never repetitive.

• Precision matters. You'll touch every subsystem and collaborate with every engineer. The quality of your work defines the reliability of the whole platform.
