Senior Hardware Engineer

Cota Robotics; Stockholms kommun; On-site; SEK 800,000 - 1,200,000; Full time

Job summary

Cota Robotics is reshaping in-store robotics with an in-house designed platform. You will own the hardware, shaping how the robot looks, how it is built, and how it scales for production. From concept and CAD to prototyping and manufacturing, your work will run in real stores within weeks.

You'll apply solid hardware fundamentals and drive decisions in a fast-moving, evolving environment where the plan can change quickly, and where quality must meet tomorrow's demo expectations.

Qualifications

• Track record of taking a physical product from concept to production.
• Comfortable in fast-moving, unfinished environments.
• Fluent in English; Swedish a plus.

Responsibilities

• Own the robot's design across concept, CAD visualization and subsystems.
• Model structures, mechanisms and enclosures in CAD.
• Prototype rapidly and iterate from field feedback.
• Design for manufacturing and assembly, taking designs through to production.
• Apply solid hardware fundamentals: GD&T, tolerances, tooling, material selection.

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. Hardware is where we need to level up the most, and you'll own it: how the robot looks, how well it's built, and how it gets produced at scale. From concept and CAD through prototyping and 3D printing to manufacturing and assembly. You'll see your work running in stores within weeks.

What you'll do

• Own the robot’s design: 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
• Set the quality bar for what ships and what doesn't

What we're looking for

• A track record of taking a physical product from concept to production. It exists in the real world, not just in renders
• High taste: in how the product looks, and in where the bar sits for what's acceptable
• High agency: you spot the problem and ship the fix without being told
• Comfortable in a fast-moving, unfinished environment where the plan changes
• Pragmatic under pressure: you know when to polish and when it just has to work for tomorrow's demo
• Fluent in English; Swedish is a plus
