The team and development are growing quickly, so we
need more people in the software department to handle the increased workload. We are looking for an addition to the software team who will work with Buy2Sells ApS software and the software from our subsidiary company Tingster ApS. As a team, the software department works across borders between both companies.

About Us

At Buy2Sell, we develop innovative solutions for e-commerce and product evaluation. We’re building a new platform where AI is playing a central role — including automated pricing, condition assessment via 3D images, and machine-learning-based analysis of product data.

Tingster is a tech startup building an auction platform app that makes it easy to buy and sell used and surplus goods. We are developing the software that connects buyers and sellers in a simple, swipe-based mobile experience. A lot of the experience from Buy2Sells solutions is used in Tingster and vice versa.

Your Responsibilities

• Develop web applications using modern frontend technologies like React and Next.js
• Backend development with Typescript and C#
• Integrate AI models for pricing, image analysis, and recommendation systems
• Deploy via cloud platforms such as AWS, Azure, or similar
• Collaborate with the team to ensure an optimal user experience
• Work with Dbs such as Supabase and Firebase

What You’ll Be Doing

Use AI to ship high-quality code aggressively. 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 using 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 to debug or manually design an algorithm instead.

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 English

We Offer

• A creative and informal work environment
• Opportunities to work with cutting-edge AI solutions
• Social events and a strong team culture
• Pension and health insurance

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
