The Chonk Team is the technical powerhouse behind Allegro’s SEO business unit. We are a specialized engineering squad (4 Developers, Project Manager, and Leader) responsible for one of the largest traffic entry points on the Polish internet.
We dont just maintain; we innovate. Last year, we launched Allegro Rankings, a product now scaling internationally. Currently, we are embarking on a high-impact mission: building a Market Trend Prediction engine using Large Language Models (LLMs). This is a rare opportunity to shape the architectural foundations of a project that turns AI experiments into production-grade business solutions.
responsibilities :
Engineering Excellence: Leading by example through mentorship, high-quality code reviews, and establishing engineering standards.
Big Data at Scale: Designing and optimizing systems that handle massive daily request volumes and extract actionable insights from vast datasets.
AI Integration: Leading the technical integration of LLMs to drive our predictive capabilities.
Cross-team Orchestration: Collaborating with over a dozen teams (Offer, Product, Listing, Category) to manage complex technical dependencies.

Ownership: You feel comfortable interacting with stakeholders and taking full end-to-end ownership—from requirements to post-deployment monitoring.
Big Data Ambitions: You want to work with tools like BigQuery and Airflow. Experience with Scala is a significant plus.
AI Curiosity (Nice to have): Familiarity with LLM tuning (LoRA, PEFT) or frameworks like LangChain/AutoGen will help you lead our newest initiatives.
Language: You are fluent in Polish (C1) and English (min. B2). Note: As our current workflow is linguistically homogeneous, Polish is a must-have for this role.
