Relay is a digital banking platform that gives self-made business owners the tools and know-how to be great with money—bringing clarity, confidence, and control to every dollar earned, so they can turn hard work into lasting success. We do this by replacing financial guesswork with real visibility, transforming cash flow from a constant source of stress into a clear signal owners can use to run stronger, more resilient businesses.
We're looking for a Senior Data Scientist to join our high-impact Data team. In this role you'll be responsible for elevating Relay's data capabilities — building predictive models, supporting experimentation across the organization, and helping the business make smarter, faster decisions. You will be a key strategic partner sitting at the intersection of data engineering and business intelligence, translating complex business questions into rigorous, actionable insights that move the needle across GTM, Sales, Finance, and Product.
We are a hybrid environment and collaborate in the office three days a week (Tuesday–Thursday).
What You'll Be Doing
Own predictive modelling work across critical business domains — including customer lifetime value (LTV), churn, retention, and early-signal customer quality assessment
Support the rollout of Relay's experiment infrastructure to teams across the org, establishing rigorous A/B testing standards and helping the org make confident, data-driven decisions
Partner closely with GTM, Sales, Finance, and Product to translate ambiguous business questions into well-framed analytical problems with measurable outcomes
Define and improve core metric definitions so the business is working from a consistent, trustworthy foundation
Deliver stakeholder-facing insights and presentations that tell a compelling story through data — not just surface numbers, but explain what they mean and what to do next
Contribute to roadmap planning and influence prioritization decisions across the data team and cross-functional partners
Mentor junior data scientists and raise the bar for business-aligned, high-impact data science across the team
Who You Are
Hands‑on experience building and deploying predictive models (e.g., LTV, churn, lead scoring) and can walk through your methodology and the business impact it drove
Deeply comfortable with SQL and Python , and can use them appropriately to run statistical analyses and solve complex problems
Strong business instincts — you understand why a metric matters, not just how to compute it, and you're energized by solving real stakeholder problems
Experience with A/B testing and experimentation , can design experiments from first principles, and can communicate results in a way that's digestible to non‑technical audiences
Thrives in ambiguous, fast‑moving environments and has a track record of ramping quickly into new domains and delivering value within weeks, not months
Explicit, confident communicator who can bridge the gap between technical work and business decisions — written, verbal, and visual
Familiarity with Snowflake and dbt is a robust plus; comfort working within a modern analytics stack is expected
What’s Important to Us
Research shows that women‑identifying and other marginalized individuals often apply only if they meet 100% of the qualifications. But no one is a perfect match on paper. If this role excites you, we’d love to hear from you and figure out together if it’s a great fit.
At Relay, we believe that diversity is key to building high‑performing teams, and creating an inclusive work environment is our priority. We are an equal opportunity employer and welcome people of diverse backgrounds, perspectives, and skills.
