We are looking for a Senior ML Engineer to join our Core team.
As an ML Engineer, you will own ML projects that improve communication activity and monetization across our products. Your main focus will be recommendation systems and user value (LTV) signals, with room to expand into adjacent areas if you want to drive new ideas. You’ll work in a team with other ML engineers, MLOps, and developers who help you ship reliably.
Your daily activities:
- Own a project end-to-end: from data and experiments to production and monitoring
- Improve existing recommender models (ranking/matching) and iterate via offline evaluation + A/B tests
- Build and refine value prediction signals (e.g., LTV@30, first purchase / conversion probability)
- Develop training and scoring pipelines; ensure data quality and reproducibility
- Deploy models to production (batch/API), package solutions into Docker, follow CI/CD practices
- Collaborate with Product and Analytics to define success metrics and turn results into product changes
- Share knowledge through code reviews, documentation, and mentoring within the team
We expect from you:
- 3+ years of hands-on classic ML development (from data exploration to production use)
- Strong Python for ML (pandas, NumPy, scikit-learn; solid coding and debugging skills)
- Solid understanding of ML algorithms and how to choose the right approach for a task
- Experience with recommender/ranking problems and their evaluation (offline metrics, A/B testing basics)
- SQL and experience working with large datasets
- Production ML experience: building training/inference pipelines, deployment, monitoring, Docker
- Cloud experience: AWS / GCP / Azure (at least one)
What do we offer:
- REMOTE OPPORTUNITY to work full time;
- Vacation 28 calendar days per year;

- Workplace organization. The company provides all employees with an equipped workplace and all the necessary equipment (table, armchair, wifi, etc.) in our offices or co-working locations. In the other locations, the company provides reimbursement of workplace costs up to $ 1000 gross once every 3 years, according to the paychecks. This money can be spent on the rent of the co-working room, on equipping the working place at home (desk, chair, Internet, etc.) during those 3 years;
