Software Developer Intern to Copenhagen's most ambitious startup, Keypitt™

Salary Unpaid
Equity To be negotiated

Are you fluent in Next.js? Do you think debugging is a sport? And do you secretly love fixing things before anyone notices they were broken? Then we might be a match.


🚀 About Us

At Keypitt™, we’re eliminating chaos from cloakrooms and replacing paper wardrobe tickets with a smooth digital experience using QR codes, Apple/Google Wallet, and (eventually) a touch of NFC magic. We’ve already run live paid pilots, partnered with Scandinavia’s largest event fair, and are gearing up for our next big wave of venue launches.


We’re a tight team based at Copenhagen School of Entrepreneurship:

  • 👩 Karla (CEO – master of people, vibes, and closing deals - and occasional bad jokes)

  • 👨‍💻 André (CTO – Norwegian builder of strong (clean) code - just like his muscles at the gym)

  • 🌍 One remote intern (and we’re growing...)


We offer a no-fluff, all-action startup vibe where learning is fast, the impact is real, and the coffee… is definitely free (we didn’t say good).


👨‍🔧 Key Responsibilities

  • Develop and maintain web applications using Next.js and TypeScript

  • Work with PostgreSQL via Supabase for our backend and Supabase Auth for authentication

  • Implement Progressive Web Applications (PWAs) to deliver smooth mobile experiences

  • Integrate and optimize Apple Wallet and Google Wallet (incl. pass updates & push notifications)

  • Collaborate with the team to improve overall performance, security, and scalability

  • Help with cloud deployment and infrastructure management

  • (Nice to have) Contribute to future payment integrations and NFC features


🧠 What We’re Looking For

You don’t need to be an expert in everything - but you should bring curiosity, commitment, and some of these:

  • Experience or strong interest in Next.js and TypeScript

  • Familiarity with PostgreSQL and Supabase (database + auth)

  • Interest in Progressive Web Apps and modern web architecture

  • Bonus points if you’ve worked with:

    • Apple/Google Wallet integrations

    • NFC tech or payment APIs

    • Cloud infrastructure tools, monitoring, logging (e.g., Sentry, LogRocket)

  • Someone who thrives in a fast-moving startup where decisions are quick and responsibility is shared.

  • Someone living in Denmark and not remote.


🤝 What We Offer

  • A real-world impact: Your code will be used at venues with thousands of guests.

  • Collaboration with a supportive tech founder, André (he’s nice, we promise)

  • Startup learning curve = vertical

  • Flexible hours (hybrid work is fine)

  • A startup atmosphere: good vibes, tons of learning, and founder-level transparency

  • Office space at CSE with free coffee, cheap canteen, ping-pong table, bad jokes, and cool startup community

  • Experience in product-focused development where your code ships fast

  • Potential equity discussions down the line if we match well


📅 Duration & Structure

  • Preferably 3+ months, but we’re flexible

  • Full-time or flex-time internship with future opportunities

  • Hybrid workweek possible (but we’d love to see you at the office in Frederiksberg some days during the week!)


Feel free to send us an application if this sounds intriguing! Be patient upon hiring proces. We will get back to every applicant fulfilling non-remote criteria. If living abroad today, but considering living in Copenhagen, please state this clearly.
