Our mobile app assists pilots in flying more efficiently, providing fuel efficiency recommendations, showcasing their environmental impact and quantifying their efforts. 




That's where you come in 

  • Be the technical anchor: You'll be the architect and visionary that defines our stack, principles and how we work as an engineering and product organisation. Our stack is predominantly based on Python on Azure (Backend), JS on React Native (Frontend), but we are always open to using different frameworks and/or programming languages.
  • Find opportunities within the data: We receive data directly from the aircraft, with more than 10.000 recorded parameters of high-quality data we are constantly looking for opportunities within.
  • Build what matters: Spend your working hours designing and developing end-to-end solutions that make the experience frictionless for pilots to become more efficient.
  • Shape the team: You'll be setting your dream team in collaboration with the remaining team members.
  • Create an amazing dev experience: Optimise the developer experience for yourself and your team members, allowing us to move the needle efficiently.
  • Establish a technical culture: Establish/promote an honest learning culture, built on trust and a growth mindset.
  • Help others shine: Constructively shape the best technical approaches, improve solutions and own code reviews that help peers and the organisation consistently grow better every day.



  • Salary: 50 - 60.000 DKK/mo. Negotiable depending on experience & salary vs equity.
  • Office: We live in Copenhagen, but believe in full flexibility and a partly remote set-up - However, as a brand new company we want you to help us shape a young, fun, engaging, and inclusive culture.

  • Naturally good at balancing now and future: What matters to you is the real life value our stakeholders get from what you are building. You sense when it's time to pay tech debt and when it can be incurred in the interest of speed.
  • A sharer and teacher: We want you to bring your experience and how you like to work into the mix, so we can create an awesome company together. Similarly, you want to learn from other people's experiences.
  • Okay with ambiguity: Early startup life is never a straight line. You don't mind that ambiguity, and can see when structure is required and when it's in the way.
