We are looking for a
Full Stack Lead Developer with AI Focus
About Us
At Buy2Sell, we develop innovative solutions for e-commerce and product evaluation. We’re building a new platform where AI will
play a central role — including automatic pricing, condition assessment via 3D
images, and machine learning-based analysis of product data.
Your Responsibilities
- Develop web applications using modern frontend technologies like
React or Vue.js - Backend development with Node.js or Python
- Integrate AI models for pricing, image analysis, and recommendation
systems - Deploy via cloud platforms such as AWS, Azure, or similar
- Collaborate with designers and AI specialists to ensure an optimal
user experience
What You’ll Be Doing
Use AI to aggressively ship high-quality code. We
expect you to stay on top of the latest tools, models, and trends in
AI-assisted software engineering. Using AI is no longer optional.
We expect you to be excellent at prompting, know when to leverage different
models, and have hands-on experience with Claude Code, Cursor, and opencode,
among others.
At the same time, we expect you to know when not to use LLMs and instead
debug or design an algorithm manually.
We Expect You To
- Have experience with both frontend and backend development
- Have worked with AI tools and ML frameworks
- Be familiar with Git and CI/CD workflows
- Have a strong interest in innovation and technological development
- Speak and write fluent Danish and English
We Offer
- A creative and informal work environment
- Opportunities to work with cutting-edge AI solutions
- Social events and a strong team culture
This Role Is For You If
- Software is your hobby. You’ve built apps for personal use or
explored side projects to learn new tech - You love styling buttons in the morning, adjusting the database
schema at noon, and deploying to production in the afternoon — you’ll
thrive here - You value speed and pragmatism. You know how to prioritize and cut
the right 5% of a feature to simplify implementation by 100x - You take security seriously, without blindly relying on modern
frameworks - You write fast software. From optimizing SQL queries to reducing
frontend reflows and choosing the right number of threads — you’re always
looking for ways to keep applications fast - You’re a generalist. You don’t need to be an expert in every area of
software development, but you’re comfortable wearing multiple hats and
learning quickly
Application

Interviews are expected to take place in week 3.
