It combines infrastructure work with product-oriented thinking in a large-scale microservices environment. 🗂️ Requirements: Strong experience in Kotlin, Experience with Spring framework, Experience in backend architecture and microservices, Willingness to work as a full-stack developer, Ability to write code in TypeScript and JavaScript, Experience with React, Experience designing APIs, Ability to handle complex JSON structures, English proficiency at B2+ level 📃 Skills: Kotlin, Spring, TypeScript, JavaScript, React, Microservices, API, JSON, Kubernetes, Docker, Consul, GitHub, GitHubActions 🏢 Description: Important things for you: Flexible working hours in the hybrid model (4/1) - working hours start between 7:00 a.m. and 10:00 a.m. We also have 30 days of occasional remote work. The salary range for this position depending on the skill set is as follows (contract of employment, tax-deductible cost): PLN 14 600 - 20 825 Annual bonus based on your annual performance and company results. Our team is based in Warsaw. About the Job Allegro is home to 1,700+ tech experts, but our team? We’re the ones building the backbone. We are part of the Core Platform, focusing on Server-Driven UI platform that allows our product teams to ship native experiences straight from the backend. We’re currently scaling Opbox Studio, our next-gen React-based stack. But we’re not just building another internal tool. We are pivoting to an Agentic AI-first approach. This means we’re leveraging specialized AI agents to automate UI generation and layout logic, effectively redefining how Developer Experience looks at scale. If you hate repetitive tasks, have a product-oriented mindset, and want to build infra that "thinks" for other developers – you’re in the right place. The Role We are looking for a Software Engineer with a strong background in Kotlin and backend solutions (Spring) who is also eager to grow and expand their skills into a full-stack role encompassing TypeScript/JS, React . We are a cross-competent, full-stack oriented team with diverse competencies, bridging the gap between backend microservices and modern web technologies. We are passionate about our internal users and work closely with various product teams. We are looking for people who: Are Polyglots at Heart: Have a strong background coding in Kotlin (and backend architectures) and are highly willing to work as a full-stack developer by actively learning and writing code in TypeScript, JavaScript, and React. 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. You will value our Developer Experience and the full platform of tools and technologies that make creating software easier. We rely on an internal ecosystem based on self-service and widely used tools such as Kubernetes, Docker, Consul, GitHub, and GitHub Actions. Thanks to this, you can contribute to Allegro from your very first days on the job. You will be equipped with modern AI tools to automate repetitive tasks, allowing you to focus on developing new services and refining existing ones (also leveraging AI support). You will create solutions that will be used (and loved!) by your friends, family and millions of our customers. You will meet the Allegro Scale , which starts with over 1000 microservices, an open-source data bus (Hermes) with 300K+ rps, a Service Mesh with 1M+ rps, tens of petabytes of data, and production-used machine learning. You will become part of Allegro Tech - We speak at industry conferences, cooperate with tech communities, run our own blog (it's been over 10 years!), record podcasts, lead guilds, and we organize our own internal conference - the Allegro Tech Meeting. We create solutions we love (and can) to talk about! Send us your CV and… see you at Allegro!
