Web Developer

Job Description

Do you want to join a fast-growing company where your work directly shapes how millions of families discover stories, learn, and fall in love with reading?

To support this, we’re looking for a Web Developer to lead the development of our internal creator & operations portal. This role is critical in establishing a scalable frontend architecture that empowers teams to build tools independently while maintaining consistency, performance, and usability.

You will help define our frontend stack (React), set standards for component libraries, and build a shared system that makes it easier for product, content, and operations to ship high-quality experiences faster.

This role is central to shaping how Lylli scales, from our reading app to our studio platform - and ensuring we can grow globally without adding complexity.

What you’ll do:

As a Web Developer at Lylli, you’ll lead the work to design and build a scalable frontend foundation for our internal tools and enabling teams to create, launch, and operate content and AI-powered features with ease.

• Develop and maintain our internal portal, creating a flexible and scalable framework for tools used across product, content, operations, and partnerships.
• Lead the development of a shared component library, ensuring consistency across tools and standardizing UI patterns using modern frontend best practices.
• Optimize performance and usability, creating internal tools that are fast, intuitive, and accessible for a wide range of users — from editors and illustrators to product managers and engineers.
• Improve developer experience, helping set up build pipelines, testing strategies, and deployment practices for frontend applications.
• Collaborate closely with backend developers, designers, and cross-functional teams, ensuring seamless integration with APIs, internal services, and content workflows.
• Shape the future of our internal tooling ecosystem, enabling Lylli to scale efficiently as we expand into new markets, languages, and reading formats.

What we’re looking for:

• Solid experience building and maintaining large-scale frontend applications, ideally with React and Node.js
• Understanding of web platforms such as Webflow and how to build reusable, scalable frontend systems.
• Experience collaborating in cross-functional teams, participating in code reviews, sharing knowledge, and solving complex product needs through strong frontend architecture.
• A passion for building tools that make other people’s work easier — and for shaping structure in a fast-moving environment.

Nice to haves:

• Experience building and deploying Java backend services.
• Strong understanding of API integrations (especially JSON-based).
• Interest in coaching junior developers and helping raise the overall technical bar.

Good to know!

This position is full time and based in our Stockholm office with a hybrid working model (part office, part working from home). We apply a 6-month probationary period. You’ll need to be located in Sweden as we are unable to support relocation. Fluency in English is required as we work with international teams and partners.
