Your responsibilities

  • Low Latency & Massive Scale: Work on high-throughput systems handling massive API traffic with a strict 50 ms time budget. Expect deep technical challenges.
  • API Security & Abuse Detection: Design and build essential tools for API management, key and resource access control, continuous abusive traffic detection, and mitigation to ensure platform compliance.
  • Modern Tech Stack & Big Data: Develop high-performance backend microservices using Kotlin and Java while leveraging GCP big data pipelines (BigQuery, Airflow) and advanced AI tools.

Our requirements

  • Have commercial experience coding in Kotlin or Java (with an eagerness to master Kotlin for our new services);
  • Value high-quality code and engineering best practices to solve complex challenges in massive-scale distributed systems;
  • Are excited to find new ways of using AI in daily work;
  • Embrace a growth mindset, value team stability, and are open to occasionally picking up frontend tasks (React is a nice-to-have);
  • Communicate effectively in Polish and English (at least a B2 level).

What we offer

  • 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.
