Description

  • Act as the founding Data Scientist and define the data science strategy, tools, frameworks, and best practices for the product.
  • Design and build Task Mining and Process Mining solutions that surface workflows, patterns, bottlenecks, and optimization opportunities.
  • Design, develop, and deploy machine learning systems and data pipelines for structured, unstructured, event, and interaction data at scale.
  • Build predictive and pattern-discovery solutions using supervised learning, unsupervised learning, representation learning, sequence modeling, and GenAI or LLM approaches where appropriate.
  • Establish dataset construction, labeling, evaluation, monitoring, feedback loops, and human-in-the-loop review foundations.
  • Own projects end to end from problem framing and experimentation through production deployment and iteration.
  • Collaborate with engineering on data instrumentation, pipeline design, deployment, and integration of production-ready services.
  • Communicate findings, tradeoffs, and technical concepts clearly to technical and business stakeholders.

Requirements

  • 5+ years of professional experience in Data Science, Machine Learning, or Applied ML roles.
  • Experience operating as the sole or lead Data Scientist on a product or team, owning problems end to end without senior DS supervision.
  • Strong experience with supervised and unsupervised ML, modern ML/data tooling, and selecting the right approach for the problem.
  • Practical familiarity with representation learning, sequence modeling, Transformers, LLMs, or GenAI systems for product use cases.
  • Experience handling large-scale structured, unstructured, event, or interaction datasets.
  • Advanced proficiency in Python and SQL.
  • Hands-on experience with tools such as PyTorch, scikit-learn, pandas or Polars, experiment tracking, and production ML workflows.
  • Experience deploying ML models, data pipelines, or intelligent systems into production.
  • Familiarity with Task Mining, Process Mining, event-log analysis, behavioral analytics, workflow automation, or adjacent domains.
  • Advanced degree in Computer Science, Data Science, AI, Statistics, Mathematics, or a related field is a plus; equivalent practical experience is strongly valued.
  • Previous experience as a first or early Data Scientist at a startup or new product line is a plus.
  • Direct experience with LLMs and Generative AI applications, especially evaluation, structured outputs, semantic labeling, summarization, or human-in-the-loop workflows is a plus.
  • Experience working with privacy-sensitive behavioral, productivity, or user-interaction data is a plus.
  • Experience with product experimentation, causal inference, or measuring the impact of workflow or process interventions is a plus.
  • Knowledge of MLOps and distributed processing frameworks such as Spark is a plus.
  • Experience with cloud environments, especially GCP, is a plus.
  • Resumes and communication must be submitted in English.
  • This is a remote role with no visa sponsorship or visa assistance provided.

Benefits

  • Remote position with eligibility to work from anywhere in Europe or South America.
  • Join Toptal’s fully remote global workforce.
  • Work on a new product in a founding role with high ownership and influence.
  • Opportunity to shape the data science function from the ground up.
  • Access to a support structure designed to encourage innovation, social interaction, and fun.
