This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Senior Machine Learning Engineer: ML Recall in Italy.

This role sits at the core of a next-generation ecommerce search and discovery platform that operates at massive global scale. You will be responsible for building and optimizing machine learning systems that directly impact relevance, recall, and business-critical outcomes such as conversion and revenue. Working on cutting-edge transformer-based and multimodal models, you will help shape how users discover products across search, recommendations, and visual shopping experiences. The environment is highly technical and innovation-driven, with a strong emphasis on production-grade ML systems and measurable impact. You will collaborate with talented engineers across distributed teams to push the boundaries of LLMs, deep learning, and large-scale data systems. This is an opportunity to work on one of the most advanced AI-driven ecommerce search infrastructures in the industry.

• Design, build, and deploy robust machine learning systems for search and discovery, including NLP, image-based, and multimodal models that improve recall and relevance.
• Develop and optimize ML/DL models using transformer architectures and LLM techniques to enhance system performance and business KPIs.
• Translate research ideas and hypotheses into production-ready engineering solutions that improve search quality, ranking, and user experience.
• Work on large-scale distributed data pipelines and ML workflows using big data technologies to support end-to-end model development and deployment.
• Collaborate closely with cross-functional engineering teams to integrate models into broader platforms and ensure system scalability and reliability.
• Conduct performance optimization and iterative experimentation to continuously improve model efficiency and business impact.

• 3+ years of professional experience in applied machine learning with a proven track record of delivering production-grade ML systems.
• Strong expertise in NLP, particularly transformer-based models, along with solid understanding of classical machine learning techniques.
• Advanced Python skills and hands-on experience with deep learning frameworks (PyTorch preferred).
• Strong experience with SQL (e.g., SparkSQL, MySQL or similar) and working knowledge of large-scale data processing systems such as PySpark.
• Ability to translate business problems into data-driven hypotheses and implement scalable engineering solutions with measurable impact.
• Strong problem-solving mindset, proactivity, and ownership-oriented approach to technical challenges.
• Excellent collaboration and communication skills, with the ability to explain complex ML concepts clearly and work effectively in team environments.
• Nice to have: experience with A/B testing, cloud platforms (AWS/GCP/Azure), Rust or C/C++, strong algorithmic thinking, and interest in performance optimization.

• Fully remote work setup, allowing you to choose your location.
• Unlimited vacation policy with encouragement to take at least 3 weeks off annually.
• Home office stipend to support your remote work environment.
• Company-provided Apple laptop for all new employees.
• Annual learning and development budget for continuous professional growth.
• Paid maternity and paternity leave for eligible employees.
• Stock options in addition to a competitive base salary.
• Regular team offsites to foster collaboration and connection.
• Opportunity to work with highly skilled peers on impactful, large-scale AI systems.
