Lead Fullstack Developer at Sweef

At Sweef, we’re on an epic mission to develop and sell Sweden’s comfiest furniture. We’re extremely selective about our range and only sell pieces we’ve personally tested ourselves, to make sure they truly deserve the title of Sweden’s comfiest. Thankfully, that work has paid off, and as the next step, we’re now looking for a new star to join our team.

We’re doing something big. Sweef has outgrown relying solely on external partners. We’re now bringing all technical development in-house to build an internal team that will set a new standard for digital furniture retail. We’re looking for you, an experienced developer who wants to be there from the start and help build what comes next.

Why Sweef, why now?

• The in-house journey: You'll be one of the first in and get to help set the standard for how we work, deploy and scale.

• Modern Composable Stack: No legacy. We run Next.js, React.js, Crystallize, Inngest and Supabase.

• AI at the centre: We encourage the use of AI tools to eliminate repetitive work, so we can focus on what actually creates value for the customer.

• High visual ambition: With 3D/AR and advanced configurators we're creating an e-commerce experience that is actually beautiful and functional.

Your role:

As a senior developer at Sweef, you will:

• Play a key role in Sweef’s shift from agency-led development to internal technical ownership.

• Use AI augmented development to build, test and ship features at a pace that helps us stay ahead of competitors.

• Continuously strive to build a better website for all of Sweef's brands (Sweef, Happy Fluffy Cloud, Nufferton).

• Work closely with the e-commerce team and partners to identify, prioritise and drive high-impact initiatives on the website with a clear focus on conversion and customer experience.

• Built together, on site: This role is based full time in Stockholm. We believe the best work happens close to the product, the team and the day to day business, so this is not a fully remote role.

Who are you?

We're looking for a senior profile who is "fullstack" in the true sense of the word – you understand both database design and how to polish a UI component with Tailwind.

Must haves:

• 5+ years in modern web development, ideally with React, Next.js and Node.js.

• Strong fullstack capability across frontend, backend and database design.

• Confidence working in production environments and making sound technical decisions around performance, maintainability and scalability.

• Ability to work closely with ecommerce and commercial stakeholders to identify, prioritise and deliver improvements that create customer and business value.

• Practical use of AI tools to improve speed and efficiency in development workflows without compromising quality.

• Experience working with headless or composable e-commerce architectures.

• Comfort working independently, taking ownership and operating in a fast moving environment.

• Sweef has a strong culture rooted in what sits at our core, namely the customer and sales. You're a real "doer", accountable, with a great attitude and always ready to pitch in where needed, whether that's code, customer contact or logistics. Nothing is left to chance.

Nice to haves:

• GraphQL knowledge.

• Familiarity with Crystallize, Supabase, Inngest, Vercel or similar tools.

• Experience working with integrations such as search, checkout, logistics and PIM systems.

• Building high performing e-commerce experiences with a focus on conversion and customer experience.

• Exposure to 3D, AR or advanced product configurators.

• Interest in helping shape future engineering ways of working at Sweef.

Our dream stack:

• Frontend/Framework: Next.js, React.js, Tailwind CSS, GraphQL.

• Backend & Logic: Crystallize (PIM), Supabase, Inngest (Event-driven).

• AI Tools: Claude Code, Cursor, Copilot (we want you to push us here!).

• Integrations: Kustom, Meilisearch, Ingrid.

• Infrastructure: Vercel, Clerk, Sentry.

Is this you?

We're looking for a person, not a piece of paper. Show us what you've built, how you use AI to deliver faster and why you want to be part of Sweef's in-house journey.
