• Well-located offices (with e.g. fully equipped kitchens, bicycle parking, terraces full of greenery) and excellent work tools (e.g., raised desks, ergonomic chairs, interactive conference rooms).


• A 16" or 14" MacBook Pro or corresponding Dell with Windows (if you don't like Macs) and all the necessary accessories.


• A wide selection of fringe benefits in a cafeteria plan - you choose what you like (e.g., medical, sports or lunch packages, insurance, purchase vouchers).


• English classes that we pay for related to the specific nature of your job.


• A training budget, inter-team tourism, hackathons, and an internal learning platform where you will find multiple trainings.


• An additional day off for volunteering, which you can use alone, with a team, or with a larger group of people connected by a common goal.


• Social events for Allegro people - Spin Kilometers, Family Day, Fat Thursday, Advent of Code, and many other occasions we enjoy.
