Job description

Join our dynamic team working on a cutting-edge advertising platform that reaches millions of users globally. As a Machine Learning Engineer, you’ll contribute to the design and development of scalable, high-performance ML pipelines and infrastructure. You'll collaborate with top-tier engineers and researchers to bring real-world impact through applied AI at scale.


🔍 What You’ll Be Doing

  • Develop and maintain scalable, low-latency ML pipelines and platforms

  • Build and optimize models using real-time and batch processing for billions of predictions daily

  • Collaborate with Data Scientists and MLOps teams on model lifecycle — from training to deployment and monitoring

  • Create proof-of-concept prototypes, experiment with new platforms, and support continuous integration and delivery

  • Streamline testing (unit, integration, stress), versioning, and automation of ML solutions

  • Research and apply the latest technologies in ML infrastructure

  • If you're experienced — you'll also get a chance to lead projects and mentor others


✅ What You Need to Succeed

  • 5+ years of experience in machine learning or data science roles

  • Strong Python skills (incl. pandas, scikit-learn) and knowledge of SQL (preferably Snowflake)

  • Experience with ML libraries/frameworks: TensorFlow, PyTorch, Scikit-learn, PySpark

  • Strong grasp of data analysis, statistics, and model evaluation

  • Good understanding of CI/CD, version control (Git), and software engineering practices

  • Ability to communicate technical insights to product teams and stakeholders

  • Openness to learn and work in a cloud-based environment


⭐ Bonus Points for

  • Experience with advertising, recommender systems, or RTB platforms

  • Hands-on with AWS ML tools (e.g. SageMaker, Airflow), Snowflake, Redis, Aerospike

  • MLOps & infrastructure experience: Docker, Kubernetes, Terraform, GitHub Actions, Prometheus, Grafana

  • Previous technical leadership or mentoring experience

  • Experience deploying ML models to production environments
