A hybrid work model requires 1 day a week in the office (Warsaw).
In Learning to Rank, we aim to develop machine learning models for ranking, serving millions of searches a day. Currently, our main area of expertise is neural text-based search and relevance. We also deal with selected machine learning challenges related to the ads system at Allegro.
Why is it worth working with us?
Being a part of Machine Learning Research team, you will be responsible for bringing to production research solutions for Allegro
While working on a new problem, you will explore it in depth and conduct literature review, looking for the most promising techniques for a given problem
You will be responsible for the preparation of the production-grade machine learning models, supporting the development team for a correctly functioning production model and meeting technical and performance requirements
You will support other teams in the implementation of tasks requiring the use of ML models. Your support will be needed both at the technical (e.g., what architecture will be appropriate for the domain) and best-practices level (e.g., building data sets, modeling, metrics, implementation of the ML-based solutions to the production)
To apply state-of-the-art solutions, you will stay up to date with the scientific progress. You will deepen your knowledge by reading the latest papers in your domain, sharing the knowledge with other team members of the research teams operating in Allegro. You will participate in scientific conferences, visiting venues where the latest discoveries are presented
You will have the possibility to share the results of your research in the scientific community, and by taking part in the scientific conferences (oral presentations, poster sessions). You will develop your scientific career, as well as Allegro's presence in the science community
In your daily work you will expand your knowledge by cooperating with people who have hands-on experience in implementation of the ML models at scale unprecedented anywhere else in Poland
In your daily work you will handle the following tasks:
Identify, implement, train, and evaluate state-of-the-art machine learning models in the domains of search and advertising – with a strong emphasis on ranking solutions
Collaborate with engineering teams who consume our models and put them in production
Participate in the code review process
Partake in seminars, prepare and deliver presentations
Work on research papers
What we offer:
Well-located office (with fully equipped kitchens and bicycle parking facilities) and excellent working tools (height-adjustable desks, interactive conference rooms)
Annual bonus up to 10% of the annual salary gross (depending on your annual assessment and the company's results)
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
Working in a team you can always count on — we have on board top-class specialists and experts in their areas of expertise
A high degree of autonomy in terms of organizing your team’s work; we encourage you to develop continuously and try out new things
Hackathons, team tourism, training budget and an internal educational platform, MindUp (including training courses on work organization, means of communications, motivation to work and various technologies and subject-matter issues)

We are looking for people who:
Have a bachelor or master degree in machine learning, mathematics, computer science, statistics or related fields
Have knowledge of deep learning techniques (neural networks, contrastive learning, semi-supervised learning) in at least one domain (information retrieval, natural language generation or understanding, etc.), ideally supported by working experience.
Are ready to work with real data that often deviate from the standard, well-developed collections used in research
Know Python and libraries necessary to work with model development (PyTorch, Tensorflow, Transformers, Pandas, Numpy, etc.)
The following are also a plus
Prior experience in running large-scale computation on cloud platform (GCP, AWS or Azure)
Prior experience in using LLMs for synthetic data generation/solving business problems
