Senior Data Scientist

Requirements:

  • A PhD in computer science, machine learning, statistics, physics, mathematics, or a related technical field – or equivalent industry experience working on advanced, data-intensive problems.
  • Expert-level proficiency in Python and SQL, with a track record of writing clean, testable, production-quality code.
  • Demonstrated experience applying advanced analytical techniques (e.g. graph algorithms, ML, statistical inference) to large, messy datasets.
  • Comfort working with EVM-based blockchain data, or strong evidence of the aptitude to ramp up quickly on EVM data structures and protocols.
  • A demonstrated ability to take ownership of projects: decomposing requirements, driving them to completion, and proactively seeking clarity from stakeholders.
  • An analytical, open-minded approach to problem solving – comfortable navigating ambiguity and willing to dive into problems outside your day-to-day scope.
  • Strong written and verbal communication skills, including the ability to explain complex methodology to diverse audiences.

Nice to Haves:

  • Familiarity with Databricks, DBT, Spark/PySpark, or similar large-scale data platforms.
  • Modified infrastructure-as-code (e.g. Terraform) or contributing to production data pipelines.
  • Mentored junior data scientists or engineers.
  • Knowledge of, or passion for, the cryptocurrency and blockchain space.

What You'll Be Doing:

  • Own the execution of one or more production data science projects, translating broad problem statements into well-scoped tasks and credible analytical results that meet stakeholder expectations.
  • Design, develop, and validate novel behavioral heuristics and algorithms over EVM (and other) blockchain data to attribute on-chain activity and uncover new insights.
  • Apply advanced techniques including graph computation, statistical modeling, and machine learning to large-scale on-chain datasets.
  • Identify and resolve inefficiencies in code, methodology, and workflows; ensure your work integrates cleanly into our production data and tooling stack.
  • Clearly articulate and defend methodology and results to both technical and non-technical stakeholders, maintaining alignment through consistent communication.
  • Mentor junior team members, contribute to technical hiring, and share knowledge.
  • Collaborate closely with peers to bring research from prototype to production.

Perks and Benefits:

  • We believe that diversity of experience and thought makes us stronger.
  • Commitment to continually revisit and reevaluate our diversity culture.
  • Encouraging applicants from all backgrounds.
  • Accessibility accommodations available for the interview process.
