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.

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 $133,200 - $162,800 For candidates who demonstrate full readiness for the defined scope of the role, the typical starting salary is $148,000. 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.
