Title: Full Stack Lead Developer with AI Focus
Location: Jyllandsgade 52B, Sønderborg
Employment Type: Full-time
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
