Seek Impact : Expect work that has a deeper meaning and want to enjoy its results - specifically by building tools that directly accelerate the work of hundreds of other engineers. Value Craftsmanship: Want to be proud of the code they create. They eagerly accept comments and share knowledge during code reviews. Are Problem Solvers: Can look for effective solutions that solve complex business and technical challenges (such as designing dynamic API contracts or handling complex JSON-based component tree structures). Are Life-long Learners: Want to constantly develop their knowledge, not only regarding backend software but also in the world of modern cross-platform rendering, Server-Driven UI, and applied Agentic AI. Communicate Effectively: Know English at a B2+ level. What’s in it for you: 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 ( see more here ), 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. And that's just the beginning! You can read more about the benefits here . #goodtobehere means that: You will join a team you can count on - we work with top-class specialists who have knowledge- and experience-sharing in their DNA. You will love our level of autonomy in team organization, the space for continuous development, and the opportunity to try new things. You get to choose which technology solves the problem and you are responsible for what you create.
