Fullstack Engineer

Where you'll be based

You'll be in-office at our central Copenhagen HQ, working alongside the whole team. We're a small team that moves fast, laughs a lot, and celebrates wins loudly - and the distance between "a user hit a problem" and "the fix is in production" is measured in hours, not sprints.

What you'll do

• Build new user-facing features end to end: data model, API, and the UI components users actually touch

• Own the frontend craft: component architecture, state, performance, and the details that make an interface feel finished rather than merely functional

• Ship features that are deeply integrated with LLMs

• Turn a compliance expert's judgment into systems: Encode how classification, risk, and requirements actually work into pipelines that scale, then make the output legible to a non-expert

• Work directly with customers and founders to decide what to build next, then build it

• Shape the architecture, tooling, and engineering culture as the team grows

You will love this job, if you are:

• A senior engineer with several years shipping production fullstack applications, fluent in TypeScript and at home in React and Next.js

• Someone with real frontend judgment: You have opinions about component APIs, interaction detail, and how a UI looks and feels

• Product-minded: You care what the user is trying to do, not just what the ticket says, and you push back when the product shape doesn't feel right

• Experienced with (or seriously hungry to go deep on) LLM-powered systems: RAG, embeddings, orchestrating multiple models in one workflow

• Someone who treats model output as an engineering problem: Evals, grounding, and failure modes, not vibes

• Comfortable with ambiguity and speed: Small team, fast decisions, no spec handed down from above

• Excited to work on-site in Copenhagen with the whole team

• A builder at heart

If you'd rather own the inference pipeline than the interface, take a look at our Backend Engineer and Data Engineer roles instead. Same team, same problems, different end of the stack.

What you get

• Ownership of the interface Europe's biggest retailers and brands do their compliance work in, on top of AI with actual stakes: our system answers "can I legally sell this product?"

• Real ownership of the code, the architecture, and a real say in what gets built

• Zero layers: You sit next to the founders, the AI team, and the compliance experts whose knowledge you're turning into software

• Ground floor of a category-defining company, backed by Y Combinator and investors betting on product compliance becoming the next big thing

• Competitive salary and equity

• An office where the pastries are mandatory

If you've read this far and thought "I want to own that interface," we'd like to meet you.
