Senior Data Scientist

The Research, Analytics & Data Science (RAD) team at Fin uses data and insights to drive evidence-based decision-making. We are a team of data scientists and product researchers who use data to unlock actionable insights about our customers, products, and business. We generate insights that build customer empathy, drive product strategy, and shape products that deliver real value. If you get excited about asking the right questions, exploring patterns in data, and turning insights into action, this role is for you.

Data Scientists in RAD partner with teams across R&D to help Fin make sense of our users, products, and business, using metrics, data, and analysis. This role will enable you to drive key data projects that directly impact our customers and millions of end users who communicate via our messaging platform daily.

What will I be doing?

• You’ll partner with product teams to help them identify important questions and answer those questions with data.
• You’ll work closely with product managers, designers, and engineers to develop key product success metrics, set targets, measure results and outcomes, and size opportunities.
• You’ll design, build, and update end-to-end data pipelines, working closely with stakeholders to drive the collection of new data and the refinement of existing data sources and tables.
• You’ll partner closely with product researchers to build a holistic understanding of our customers, products, and business.
• You’ll influence our product roadmap and product strategy through exploratory analysis and quantitative research.
• Increasingly, you will also:
• Use AI-assisted tools (e.g. Claude Code, Cursor) to accelerate analysis, coding, and insight generation.
• Identify opportunities to automate your own workflows and reduce time spent on repetitive tasks.
• Build scalable data products (dashboards, models, internal tools) that enable stakeholders to self-serve insights.
• Help teams interact more directly with data (e.g. through better abstractions, semantic layers, or AI-powered interfaces).
• Raise the bar for how AI is used within RAD - sharing patterns, workflows, and best practices.
• Craft clear, compelling data stories and communicate recommendations across R&D and the broader company.
• Contribute to and shape core RAD foundations, improving how the team operates.

What skills do I need?

• 5+ years experience working with data to solve problems and drive evidence-based decisions.
• Strong SQL skills and solid grounding in statistics.
• Experience working closely with product teams.
• Proven track record of delivering actionable insights that drive measurable impact with minimal supervision.
• Strong product intuition, business acumen, and ability to connect analysis to strategy.
• Excellent communication skills (technical and non-technical), with a focus on driving decisions and outcomes.
• Strong ownership, curiosity, and growth mindset.
• Experience with a scientific computing language (e.g. Python).

And increasingly important:

• Ability to effectively use AI tools (e.g. Claude Code, Cursor) to accelerate and improve your work.
• A mindset of automation and leverage - looking for ways to scale your impact beyond one-off analyses.
• Comfort working in ambiguous, fast-evolving environments where tools and workflows are rapidly changing.

Bonus skills & attributes

• Experience with data modeling and ETL pipelines (especially dbt).
• Experience building internal tools, data products, or self-serve analytics capabilities.
• Experience leveraging AI across the data workflow - from ideation and coding to analysis and communication.

Benefits

• Competitive salary and equity in a fast-growing start-up.
• Unlimited access to Claude Code and best-in-class AI tools; experimentation & building is encouraged & celebrated.
• We serve lunch every weekday, plus a variety of snack foods and a fully stocked kitchen.
• Regular compensation reviews - we reward great work.
• Peace of mind with life assurance, as well as comprehensive health and dental insurance for you and your dependents.
• Open vacation policy and flexible holidays so you can take time off when you need it.
• Paid maternity leave, as well as 6 weeks paternity leave for fathers, to let you spend valuable time with your loved ones.
• MacBooks are our standard, but we’re happy to get you whatever equipment helps you get your job done.
