Senior Data Scientist I

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.

Please note that we are a hybrid environment and choose to 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

• You have 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

• You're deeply comfortable with SQL and Python, and can use them appropriately to run statistical analyses and solve complex problems

• You bring strong business instincts — you understand why a metric matters, not just how to compute it, and you're energized by solving real stakeholder problems

• You have 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

• You thrive in ambiguous, fast-moving environments and have a track record of ramping quickly into new domains and delivering value within weeks, not months

• You're a clear, confident communicator who can bridge the gap between technical work and business decisions — written, verbal, and visual

• Familiarity with Snowflake and dbt is a strong plus; comfort working within a modern analytics stack is expected

The Interview Process

• Stage 1: A 45-minute Google Meet video call with a member of the People Team

• Stage 2: A 60-minute Google Meet video call with the Hiring Manager

• Stage 3: A 45-minute in-person interview with a member of our Leadership team

• Stage 4: A take-home case study, followed by a 60-minute Google Meet video call with members of our Data team.

Our Compensation Approach

We believe Relayers should feel rewarded for the impact they have on our mission and growth. Compensation follows impact. As impact increases, compensation grows, and we do not limit compensation changes to a once-a-year review cycle.

The annual salary range for this role is $144,000 - $176,000

For candidates who demonstrate full readiness for the defined scope of the role, the typical starting salary is $160,000. Offers below this point reflect candidates we believe can grow into the full scope of the role with support and development. Offers above this point reflect impact that meaningfully exceeds the role’s defined expectations or an expanded scope from day one.

We encourage you to have a conversation with your recruiter and ask questions about compensation throughout the hiring process. For more information on our compensation philosophy and perks and benefits, visit our Candidate Hub.

Why Relay Might Be the Perfect Fit For You

• You push relentlessly for reinvention: You’re built to constantly ask, “How can this be better?” Change excites you and you drive it. 

• You crave autonomy: We trust our team with big challenges and the freedom to solve them. If you’re someone who takes initiative, is comfortable taking risks, and seeks input when needed, you’ll find the freedom here empowering.

• You own your work: You take pride in your work, follow through on commitments, and feel a deep sense of responsibility for outcomes, not just tasks.

• You treat comfort as a red flag: You seek growth. When things feel too comfortable, you lean into change. You’re excited about  stepping into the unknown and navigating new terrain to create something better alongside your team. 

• You care about impact, not noise: You care deeply about the substance of your work. You measure success by results, not recognition and you let your work speak for itself. 

• You’re energized by complexity and ambiguity: You enjoy tackling problems that don’t come with a playbook. You’re comfortable building from scratch, iterating as you go, and collaborating to shape the best path forward.

• You seek out feedback: We value directness, clarity, and respect. We believe honesty fuels great work and career growth. You see feedback as a tool for learning and improvement, and you know that open, honest dialogue is key to achieving the best results — together.

• You’re here for more than a job: At Relay, everything we do is in service of our mission to help small businesses thrive. To drive impact and have purpose here, that mission must matter to you too.
