Staff Data Scientist - Growth & Expansion

About the Role:

We're hiring a Staff Data Scientist, Growth & Expansion to own one outcome - customer growth - across every team that shapes it. Growth at HighLevel isn't the property of a single team: onboarding, activation, trial-to-paid, multi-product adoption, and expansion are driven by the Growth org, GTM, Finance, and product teams across the company. Your job is to connect those efforts with a rigorous, segment-level understanding of what actually turns a new account into a growing, multi-product customer - in a B2B2C model where an agency signs up and then activates sub-accounts - so the company invests behind what compounds, not just what converts.

This is a broad, cross-functional role. You'll work closely with Growth, GTM, Finance, and any product team whose work drives customer growth; you report centrally to Product Analytics & Data Science for craft and standards and carry the growth outcome across organizational boundaries. You'll work amid a data foundation still being built, consuming governed and certified sources rather than rebuilding source logic, and raising the bar as you go. This is a hands-on, direction-setting Staff role - you advise Growth, GTM, and Finance leaders and set growth-measurement standards that analysts on adjacent teams adopt, with a path to grow a pod as the mandate scales.

Responsibilities:

Own the customer-growth outcome end to end - onboarding, activation, TTP, multi-product adoption, and expansion revenue - across Growth, GTM, and the product teams that drive it, with clear, trusted metrics at each stage
Identify which early and mid-lifecycle behaviors predict expansion (second product, higher plan, add-on attach), not just initial conversion, and turn it into a prioritized growth agenda
Connect product signal to GTM/marketing spend and Finance's growth targets - a single evidence base the whole growth motion shares
Model the B2B2C dynamic - agency → sub-account activation and expansion - and surface where compounding value is created or lost
Partner with the Experimentation & Causal Inference lead to design and read growth experiments rigorously; hold causal vs. correlational claims to a real bar
Partner with the Product Strategy & Growth org on the TTP/churn and add-ons charters so definitions and models are shared, not duplicated
Set the technical direction for how customer growth is measured company-wide - own the canonical metrics, segment definitions, and value model on governed, certified data that other teams build on
Build the growth-measurement and causal-inference framework - the standards and reusable methods that Analytics Engineering and adjacent DS teams reuse beyond this mandate
Translate findings into decision-grade guidance for Growth, GTM, Finance, and product leaders; influence roadmap and investment without owning them
Act as a trusted analytical advisor to Growth, GTM, and Finance leaders, and set the analytical standards that DS and analysts on adjacent teams adopt - raising the bar without direct authority
Flag data gaps to Analytics Engineering and shape the event taxonomy the funnel and value model depend on
Use AI tooling (Claude and similar) to move faster on exploration, documentation, and analysis

Requirements:

9+ years in product/growth analytics, data science, or applied statistics, with deep experience across activation, retention, conversion, and expansion motions
Track record where you built a metric or value framework that multiple teams drove real outcomes with - this role owns an outcome across boundaries, not reports for one team
Strong applied statistics - you design analysis to the causal question and know the failure modes of correlational reads
Fluency partnering on experiments (A/B design, power, guardrails) and interpreting results honestly
Strong SQL and working proficiency in Python; comfort in a Snowflake + dbt environment
Experience turning behavioral and revenue data into segment-level insight that changed a product, growth, or GTM decision
Comfort amid imperfect, in-progress data - you consume governed sources and raise the bar rather than rebuilding pipelines
Cross-functional influence - you align Growth, GTM, Finance, and product leaders on shared numbers without direct authority

Nice to Have:

B2B SaaS, CRM, or product-led growth background, especially freemium/trial and land-and-expand motions
Usage-based/consumption or add-on revenue exposure (expansion surfaces)
Familiarity with Statsig or a comparable experimentation platform
Exposure to AI-assisted analytics workflows; experience mentoring analysts

Success in this role looks like:

Growth, GTM, Finance, and product teams share one trusted value model connecting adoption to TTP, retention, and expansion - and invest behind it
Expansion drivers (not just conversion drivers) are named, quantified by segment, and on the roadmap across the teams that own them
Leaders across the growth motion make roadmap and spend calls off your analysis, not gut feel
The customer-growth mandate has reusable patterns and the foundation to scale beyond one IC
