Benefits offered by this job

Meaningful equity

Ownership of hardware

Job summary

Cota Robotics in Stockholm is seeking a hardware design engineer to own the physical robot from concept and CAD through prototyping, 3D printing, and manufacturing at scale, with tests in live stores within weeks.

You will work in a small team at Sankt Eriksgatan, moving fast in an unfinished environment where plans evolve. This founding role offers meaningful equity and fast real-world demonstrations of your designs.

Qualifications

• Attitude first: high agency, you spot the problem and ship the fix without being told.
• A strong track record in hardware design, or an unreasonable appetite to build one.
• Comfortable in a fast-moving, unfinished environment where the plan changes.
• Ready for long weeks when it matters and demos that have to work tomorrow.
• Fluent in English; Swedish is a plus.
• You must already have the right to work in Sweden, as visa sponsorship is not available at this stage.
• A founding role with ownership of the hardware.
• Meaningful equity.
• See your designs running in real stores within weeks.

Responsibilities

• Concept and visualize new products and subsystems.
• Model structures, mechanisms and enclosures in CAD.
• Prototype rapidly and iterate from what you see in stores.
• Design for manufacturing and assembly, and take designs through to production.
• Apply solid hardware fundamentals: GD&T, tolerances, tooling, material selection.
• Move fast.

Job description

Cota Robotics puts robots to work in retail stores. They take on the repetitive, time-consuming jobs like inbounding goods, replenishing shelves 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.

The role

We design and assemble our own robot platform in-house. It's CE-marked and working in customer stores, and it's far from done. You'll own the physical robot: from concept and CAD through prototyping and 3D printing to manufacturing and assembly at scale. You'll see your work running in stores within weeks.

What you'll do

• Concept and visualize new products and subsystems
• Model structures, mechanisms and enclosures in CAD
• Prototype rapidly and iterate from what you see in stores
• Design for manufacturing and assembly, and take designs through to production
• Apply solid hardware fundamentals: GD&T, tolerances, tooling, material selection
• Move fast

What we're looking for

• Attitude first: high agency, you spot the problem and ship the fix without being told
• A strong track record in hardware design, or an unreasonable appetite to build one
• Comfortable in a fast-moving, unfinished environment where the plan changes
• Ready for long weeks when it matters and demos that have to work tomorrow
• Fluent in English; Swedish is a plus
• You must already have the right to work in Sweden, as unfortunately we're not able to offer visa sponsorship at our current stage
• A founding role with ownership of the hardware
• Meaningful equity
• See your designs running in real stores within weeks
