Job description

At Hemnet, we build one of Sweden's most widely used digital services. Every day, we help people navigate some of life's biggest decisions, and that brings high expectations for quality, reliability, and long-term thinking.

We're now looking for a Fullstack Developer to join our B2B & Seller Domain. This team builds products and services that help homeowners and agents make the most of their opportunities in the housing market.

About the role

You'll be part of an experienced, cross‑functional team working across both user‑facing features and backend systems. You'll contribute through hands‑on development, technical leadership, and close collaboration with Product Managers, Designers, Analysts, and Engineers. Together, you'll build solutions that create real value for sellers.

You'll design, build, and maintain scalable backend services using Ruby, Node.js and Nest.js, contribute to frontend development in React, and support and evolve APIs across GraphQL and REST. You'll also play an active role in our transition toward a more service‑oriented architecture, helping break down complex problems and move monolithic systems into modular services over time.

Beyond day‑to‑day development, you'll take part in technical discussions, contribute to architectural direction, support other engineers through collaboration and knowledge sharing, and help us continuously improve code quality, performance, and developer experience. We also hope you'll contribute to a team culture where different perspectives are valued and people can grow together.

Who we think you are

Our current stack includes Ruby and Node.js on the backend and Next.js on the frontend. You'll work with Ruby in this role, but we don't expect you to know everything from the start.

We think you're an experienced engineer who enjoys building production‑grade systems and working through complex problems together with others. You care about code quality, maintainability, and creating solutions that hold up over time.

You're comfortable contributing to technical decisions, and you like collaborating across disciplines to build products that are useful and thoughtful. You don't need to tick every box on day one, what matters most is that you bring solid engineering experience, a learning mindset, and a generous way of working with others.

What you’ll do

• Build and improve Hemnet's products across the system.
• Take part in technical discussions and architectural decisions
• Work closely with product, design, and analytics.
• Contribute to a sustainable pace, high quality, and a great developer experience.
• You’ll use AI tools as part of your day‑to‑day work, for example to explore ideas, speed up implementation, improve code quality, and support learning and collaboration across the team.

A Note on Inclusion

At Hemnet, we believe that diversity in gender, sexual orientation, ability, neurodiversity, cultural background and life experience makes us stronger. We welcome applicants of all identities and backgrounds.

If you meet many but not all of the requirements, we encourage you to apply. We value curiosity, a strong sense of purpose and the motivation to learn and grow, alongside your skills and experiences.

Hybrid Way of Working

Our vibrant office in central Stockholm is the hub of our collaboration and culture, providing a lively space that fosters team spirit. We come together in the office three days a week, with two flexible remote days. To be part of our team, it's essential to be based in or near Stockholm.

Please note that we're unable to provide relocation assistance for this opportunity.
