Frontend Developer

Senior Product Frontend Engineer (AI)

**Stockholm, Sweden Full-time**

We’re looking for an exceptional frontend engineer who doesn’t just build interfaces - they build products people love. Someone who combines outstanding technical ability with strong product intuition, sweats the details, and thrives in a fast-moving startup environment.

This is an opportunity to join early, work directly with the founders, and have a significant influence on the product, technology, and company.

What you’ll do

• Build beautiful, fast, AI-native user experiences.
• Work closely with founders, product, and design to turn ideas into products customers love.
• Prototype, ship, learn, and iterate quickly.
• Own features end-to-end, from concept through launch and continuous improvement.
• Help define how users interact with AI—not just how software looks.
• Improve our frontend architecture, design system, and developer experience.
• Use data and customer feedback to continuously improve the product.

We’re looking for someone who

• Is an exceptional frontend engineer with strong product instincts.
• Has experience at a high-growth startup, or at a world-class technology company with a strong product culture.
• Has deep expertise in React, TypeScript, and modern frontend development.
• Cares deeply about design, usability, performance, accessibility, and user experience.
• Has a high bar for quality and an eye for detail.
• Thinks like an owner and enjoys solving customer problems.
• Loves building and shipping quickly.
• Is excited about the opportunity AI creates to reinvent software.

Bonus points

• Experience building AI-powered products or developer tools.
• Experience designing conversational, agentic, or AI-assisted user experiences.
• Experience with design systems and animation.
• Experience with Next.js, GraphQL, or full-stack development.
• Familiarity with LLMs, AI APIs, or modern AI application frameworks.

Why join?

• Build at the forefront of AI.
• Join early and help shape the product and engineering culture.
• Work alongside ambitious, high-calibre teammates.
• High ownership, meaningful equity, and the opportunity to make an outsized impact.
• Solve difficult problems that matter for customers.

If you’re excited about building category-defining AI products - and want to create experiences that feel magical rather than merely functional - we’d love to hear from you.
