Junior Hardware Engineer

Cota Robotics puts robots to work in retail stores. They take on the repetitive, time-consuming jobs like stocking shelves, inbounding goods and sorting stock, currently mostly overnight. They're driven from our control room in Stockholm and increasingly run on their own. We raised a €1.92M pre-seed in August 2026 and are live with retailers in Sweden and Finland. We're a small team based at Sankt Eriksgatan in Stockholm, where half the office is our own dark store.

About the role

You’ll work hands-on with the robot and make it survive real stores. Mounts, brackets, grippers, actuators, sensors, wiring, whatever the robot needs. Some of it will be properly engineered. Some of it needs to work by Thursday. You should be comfortable with both.

What you’ll do

• Build, fix, and improve electrical and mechanical subsystems on the robot

• Deploy robots into stores and see firsthand where they break

• Turn what you learn into the next version of the hardware

• Design, 3D-print, assemble and test parts, fixtures and prototypes

What we’re looking for

• Background in mechatronics, mechanical or electrical engineering, robotics, or similar

• A fast-learning generalist and tinkerer who’s taken more apart than they’ve put back together

• High agency: able to make something work in the short term and improve it later, without confusing the two

• Comfortable with CAD basics and hands-on prototyping

• Fluent in English

• You must already have the right to work in Sweden, as unfortunately, we’re not able to offer visa sponsorship at our current stage

How to apply: Tell us about something you built or fixed on your own, and link to it (project, repo, video, photos).

Why join

• Build on real robots operating in real stores

• Work across disciplines rather than in a narrow silo

• Meaningful equity and a chance to shape the next version of the robot
