Job Profile Summary

Our growing IT Analytics and Data Science team is spread in US, Poland, India and Singapore with a diverse set of skills and backgrounds. We work with our internal customer in departments like Sales, Marketing, Finance, Operations and more, to deliver machine learning solutions to critical data-driven problems directly connected to company’s top-level goals.

We have a variety of datasets generated by our internal systems, that includes tabular/panel data and text (and even videos) and datasets acquired from third-party providers. We have several ongoing projects related to revenue, retention, growth, risk mitigation and a vast green field to explore new ideas. To deliver such solutions we use multiple machine learning tools like classification, regression, clustering, time series, anomaly detection, NLP, graph models and constantly exploring new ones.

We are building our ML platform considering MLOps best practices to increase productivity and reliability across several machine learning use cases. We use GCP (Google Cloud Platform) and its cloud components to architect our solutions, using mostly python, SQL and popular data science libraries for all our work while keeping flexibility to try new technologies along the way.

  • ML thought leadership: Evangelize a strong vision and roadmap on delivering value while developing new capabilities to enable business teams with data. Be a thought leader for statistics and machine learning, providing guidance for your team and assuring the correct tools are chosen and properly implemented
  • People management: Lead team of 5+ data Scientists in Poland and work with cross functional teams located in US, India, Singapore and other parts of EMEA
  • Engage with internal customers: Conduct requirements workshops with stakeholders to identify and deeply understand business problems. Communicate complex concepts and the results of the analyses in a clear and effective manner through creative visualization and presentation skills
  • Data expertise: Work with large volumes of data; extract and manipulate large datasets using tools such as Python and SQL. Leverage a state-of-the-art ML platform to train and deploy models. Drive scalability, reliability and efficiency across projects

Required skills

  • CS fundamentals: You have earned at least a B.S. (MS / PhD desired) in Computer Science/ Statistics/ Applied Math/ Operational Research or related degree and you have a strong ethos of continuous learning
  • Software and ML development experience: You have 6+ years of professional software development experience with languages and systems such as Python and version control (GIT), with good analytical & debugging skills. You have 3+ years in building machine learning or deep learning solutions
  • People management: You have 1+ years of experience leading and/or managing teams of data scientists, providing mentorship and guidance to the team
  • Machine learning: You have worked with python libraries like pandas, numpy, scikit learn, tensorflow, keras, in developing different ML/AI solutions. Knowledge about using classification, regression, time series, NLP, anomaly detection, clustering and other common ML tools. Experience with model interpretability (lime, shapley and similar) is a plus
  • Data manipulation: Deep interest in understanding the datasets related to the projects, spot and communicate data quality issues, knowledge of different feature engineering techniques to feed models with the best possible data
  • Languages & tools: Experience in developing solutions in Python is a requirement. Experience in SQL is a must
  • Cloud environments: You have working knowledge of cloud environments like GCP (preferred), AWS or other cloud data platforms
  • Project management: You demonstrate excellent project and time management skills, exposure to scrum or other agile practices in JIRA. Deep understanding of CRISP-DM or similar methodologies
