About the role

  • You will be accountable for CAC efficiency outcomes, identity match rate and audience quality on paid platforms, and measurable lift from ML-driven lifecycle interventions - all built from greenfield.
  • This is a role for someone energized by the scope of what isn't there yet.
  • This is a hybrid position with on-site expectations in our New York Headquarters or San Francisco/Bay Area Office, 2-3 days per week.

Responsibilities

  • 0→1 Martech Architecture: Design and build Flex's martech stack from the ground up - CDP, identity spine, attribution infrastructure, lifecycle orchestration, and paid media data pipelines.
  • Make deliberate build vs. buy decisions with limited resources and a clear sequencing logic.
  • Attribution and Measurement Infrastructure: Build the measurement architecture that tells us what's actually working in paid acquisition - incrementality testing, MMM, modeled conversions. Move Flex from last-click to something defensible.
  • Identity and Data Architecture: Design the identity spine that stitches anonymous ad exposure to app install to authenticated user to payment behavior. Own match rate outcomes.
  • AI/ML Intelligence Layer: Layer ML-driven capabilities on top of the bought stack - propensity scoring, predictive LTV, dynamic audience segmentation - that create compounding marketing leverage over time.
  • Paid Media Data Infrastructure: Own the data layer underneath paid social - server-side conversion APIs, MMP integration, audience sync across Meta and TikTok and be directly accountable for CAC efficiency.
  • Lifecycle and Campaign Orchestration: Build the lifecycle infrastructure that powers onboarding sequences, payment reminders, re-engagement programs, and cross-vertical messaging as Flex expands beyond rent into other biller verticals.
  • Platform Leadership and Stakeholder Engagement: Act as the primary technical thought partner to the CMO - translating infrastructure capabilities into growth strategy, and translating marketing needs into technical requirements for engineering and data science.
  • Data Governance and Compliance: Design consent management, data governance, and regulatory compliance into infrastructure design.
  • We are growing quickly, but deliberately, with a focus on building an inclusive culture.

Requirements

  • you know what it feels like when the playbook doesn't exist
  • you have hands-on experience with incrementality testing, MMM, or modeled conversions

  • Attribution architecture depth - you've built measurement systems that work when signals are degraded; you have hands-on experience with incrementality testing, MMM, or modeled conversions
  • Paid media data fluency - direct accountability for CAC going up or down; hands-on experience with server-side conversion APIs, MMP integration, or paid social audience infrastructure
  • 8+ years of product management experience specifically in martech, growth infrastructure, or data products -directly building and owning the stack, not in adjacencies
  • 0→1 build experience in a high-growth environment - you've built a martech function, a data platform, or a measurement infrastructure from scratch with limited resources and high ambiguity
  • Attribution architecture depth - you've built measurement systems that work when signals are degraded
  • CDP ownership - you've run the vendor evaluation, made the build vs. buy call, managed the integration, and been accountable for match rate and activation outcomes
  • Paid media data fluency - direct accountability for CAC going up or down
  • Consumer product context - your customers are individuals, not enterprise buyers
  • bonus if that context is fintech
