Job Description

Senior Data Scientist

Optimum

• Own end-to-end methodology for causal inference, identification strategies, and predictive modeling. • Design, run, and evaluate experiments — from hypothesis formulation through power analysis to result interpretation. • Work on product initiatives where data signals are the core deliverable, not just a supporting artifact. • Partner closely with Product, Economics, and Research as primary stakeholders to translate business questions into rigorous analytical frameworks. • Work with Engineering on implementation of models and evaluation pipelines, ensuring analytical work is production-ready. • Produce actionable insights and present complex methodology to both technical and non-technical audiences clearly and concisely. • Document approaches, assumptions, methodologies, and results to a high standard — building institutional knowledge that scales with the team.

Job Requirements

  • Postgraduate degree in Statistics, Mathematics, Computer Science, Economics, Data Science, Engineering or a related quantitative discipline.
  • Minimum of 5 years of hands-on experience in a data science or applied research role.
  • Strong foundations in causal inference and experimental design (A/B testing, quasi-experiments, diff-in-diff, IV, etc.).
  • Proficiency in predictive modeling: regression, classification, time-series, and familiarity with modern ML frameworks.
  • Statistical rigor — you know when a result is meaningful and when it isn’t, and you can defend that position.
  • Fluency in Python (pandas, scikit-learn, statsmodels) and SQL; comfort working in cloud data environments (e.g. BigQuery, Snowflake, or equivalent).
  • Strong written and verbal communication; you can turn a p-value into a product decision.

Benefits

  • Ownership from day one — you will define methodology, not just apply it.
  • Work on genuinely hard problems at the edge of networking and decentralized systems.
  • Close collaboration with a small, senior, cross-functional team.
  • Competitive compensation, equity, and flexibility.
  • Flexible time off.
  • Fully remote — work from wherever you do your best thinking. Most of the team operates on ET or CET, so we look for meaningful overlap with those windows.
