Massive Scale: Design, build, and optimize systems that handle thousands of requests per second. This is high-availability, high-performance engineering in practice.
Master advanced technologies: Work in a world-class, cloud-native environment (GCP). Our core technologies include Java, Kotlin, Spring, MongoDB, microservices, and Airflow (Big Data).
True Ownership & Autonomy: We live by the "you build it, you run it" philosophy. You'll join an agile, autonomous team with full ownership of your microservices—from design to deployment.
Engage with diverse business initiatives: Partner with PMs to analyze requirements and drive numerous business initiatives across Allegro.
Drive innovation with LLM: Participate in the development of new tools based on Large Language Models.
Work with an experienced team: Benefit from a high-agency environment with support and development opportunities provided by senior experts. As a senior developer, you will also have the opportunity to share your knowledge and mentor colleagues with less experience.
Ensure system reliability: Maintain the stability of complex architectures through participation in on-call duty.
Our requirements
Commercial experience: 5 years of experience in building and maintaining complex, high-scalability systems.
Strong technical foundation: Proficiency in Java (primary) and Kotlin, with a focus on reactive programming.
