Senior Data Scientist

Chainalysis is inspired by solving the hardest technical challenges and creating products that build trust in cryptocurrencies. We're a global organization who thrive on the challenging work we do and doing it with other exceptionally talented teammates. Our industry changes constantly, and our job is to create user-facing products supported by our best-in-class data, allowing us to adapt to those rapid changes and bring maximal value to our customers.

In this role, you'll: - 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.

We're looking for candidates who have: - 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.
