UBsend is a scale-up company aiming for developing and implementing state-of-the-art logistic solutions within the parcel industry. We ensure that companies of all sizes receive optimal solutions for their parcels in terms of carrier selection, lead time, prices, track and trace and customer experience. We strive to be the leading integration platform, growing rapidly and working with many well-known B2B and B2C clients. We are a company with a multinational culture, counting roughly 80 employees between our offices in Aarhus and Copenhagen. We keep the daily motivation high through social events and a down-to-earth tone with lots of humor and an inclusive atmosphere.

Your profile

We tackle a wide range of projects, so if you love staying busy and enjoy variety in your workday, you'll fit right in with us. You have an entrepreneurial spirit and always go the extra mile to achieve your goals and meet deadlines.

Since we're not a large corporate IT department, you'll be given significant responsibility, making it crucial that you're comfortable making independent decisions when needed. You bring a positive and innovative mindset and aren't afraid to pitch and implement your ideas. You thrive in an informal environment and are eager to both learn more and share your knowledge. In short – you're a proactive “go-getter” who loves a challenge!

We look forward to hearing from you
