Full stack developer

Senior Full-Stack Engineer (Founding Team)

The Company is a Stockholm-founded, US-focused B2B SaaS startup building the post-sale operating system for the commercial furniture industry. Our platform connects furniture dealers with their enterprise customers through digital closeout, warehouse management, and service request workflows.

Our enterprise customers include Apple, American Express, and several other Fortune 500 companies. We also have a commercial agreement in place that will enable us to onboard a significant portion of the dealer market within the next year.

We’re now looking for a senior engineer to join us at a pivotal stage.

The role

You’ll become one of the first technical engineer and take ownership of engineering together with the founder. Today the team consists of the Founder/CEO and one frontend-focused developer. We’re looking for someone who enjoys building products from the ground up and is excited by taking ownership rather than joining a large engineering organization.

Your first major mission will be to lead our migration from Firebase to Supabase while rebuilding our backend architecture in preparation for a large-scale dealer rollout.

You’ll work closely with customers, shape product decisions, and have genuine influence over both the technical direction and the company itself.

For the right person, this role has a clear path toward a CTO / Founding Engineer / Co-founder-level position as the company grows.

* Lead the migration from Firebase to Supabase

* Design and build scalable backend architecture

* Own features end-to-end, from idea to production

* Work directly with customers to shape the product

* Make key architectural and technical decisions

* Help build the engineering culture from the beginning

Tech stack

* React.js

* TypeScript

* Next.js (API Routes)

* Supabase (Postgres + Auth)

* styled-components

* TanStack Query

* Vercel

* Claude API / Claude Code

We’re looking for someone who

* Has 4+ years of professional software engineering experience

* Is stronger on backend than frontend

* Has experience building production SaaS products

* Enjoys working in early-stage startups or has 0→1 experience

* Is comfortable owning architecture and making technical decisions

* Wants responsibility and long-term impact rather than simply executing tickets

Location

* Remote, or

* Stockholm (preferred if you’re based in Sweden)

Both employment and freelance/contract arrangements are possible.
