What if... your
solutions scaled
at Allegro?

We build for both sides of the market. For businesses, we develop everything from onboarding and verification to Allegro Ads, API integrations, and complex billing systems. For consumers, we craft seamless experiences on every platform – web, iOS, and Android – constantly refining the searching and comparing process, as well as the entire purchase journey. Our Marketplace team is the bridge between millions of buyers and sellers. Operating across dozens of dev teams, we work hand-in-hand with UX researchers and data analysts. We thrive on experimentation: testing hundreds of scenarios every month and translating data-driven insights into real product features.

We are the backbone of Allegro. By designing and maintaining our core infrastructure, we enable other teams to focus on what they do best. We equip our staff with the necessary hardware and software to maximize productivity and build robust tools for our customer service departments. We manage the technology stack that drives the platform: private Data Centers, cloud solutions, automated deployment pipelines, and internal SDKs that ensure security and compliance. Our mission is to keep Allegro highly available and secure, providing hundreds of international teams with a modern, efficient ecosystem. We make sure our colleagues have the right tools to build world-class products and deliver market-leading support.

Our area of operation is a vital link in the entire logistics chain. Thanks to our work, Allegro customers know exactly when they can expect their orders, as we specialize in delivery time forecasting. How do we do it? We drive calculations using statistical algorithms and a Machine Learning engine that serves predictions over 12,000 times per second. We select the best-fitted delivery methods for each customer, handling traffic up to 1,000 RPS with a 200ms response time. We also manage integrations with courier companies that power services like Smart! free delivery – processing up to 500 parcel status updates per second. Our goal is simple: to provide customers with the most convenient delivery options on the market.

Data & AI is the core intelligence behind Allegro. We run AI and Data Science implementations (including search engines, recsys, automated support, and fraud detection) at an unprecedented scale. To push our ML solutions and automation further, we are looking for curious, senior-level engineers to join us. Your mission will be to create stable, high-throughput systems (capable of processing millions of RPS) and to bridge these services with batch and streaming processing for massive Big Data sets in public cloud environments.

We build the tech behind Allegro Pay. Our scope covers the entire payment lifecycle: from processing transactions and managing post-sales operations (repayments, splitting payments into installments, overpayments) to building internal CRM systems and maintaining robust automated test suites. In the Data & AI space, we focus on implementing ML models and high-end algorithms to optimize financial products. We operate in specialized teams focused on implementation and development of new functionalities within oboarding, sales, post-sales, and insurance. Beyond product features, we develop our core technical platform, infrastructure, and frontends (Web, iOS, Android) for Allegro Pay and Allegro Care. Our work also involves managing complex two-way integrations with external financial entities (credit bureaus, AIS/PSD2, debt collection) and maintaining high-availability systems for consent management and notifications.

We are a team of talented designers, UX analysts, researchers, UX writers, and communication experts. Our mission is to make buying and selling on Allegro as seamless and convenient as possible. We are truly passionate about great UX – in everything we do, we pay attention to every single detail. We have a deep understanding of design principles, industry trends, and user behavior. We experiment with new methodologies and collaborate on conceptualizing, prototyping, and refining products until they are market-ready. We are constantly looking for ways to evolve our design system and love sharing our knowledge with the wider community by organizing events like the UX Research Confetti conference.

Our team is responsible for operating and maintaining the existing Mall and CZC platforms, which includes both 1P and 3P operations in multiple countries. Additionally, we are supporting the successful launch of Allegro platform and business operations on the new platform. The team works with state-of-the-art tech in a heterogeneous environment - using multiple stacks in a distributed microservice architecture.
