Staff Data Scientist, Product

Location: Open / Hybrid / Remote (role-dependent)

Level: Senior Individual Contributor

Role Overview

This role sits within a growing Product Analytics & Data Science team and serves as the technical anchor for experimentation, causal inference, and advanced statistical methods. The Staff Data Scientist will play a critical role in elevating how experiments are designed, executed, interpreted, and trusted across the organization.

Beyond technical execution, this individual will be responsible for shaping experimentation culture, improving analytical rigor, and influencing product and executive stakeholders without direct authority. This is a high-impact IC role for someone who thrives at the intersection of data science depth, product thinking, and organizational influence.

Key Responsibilities

Experimentation & Causal Inference

  • Own and evolve the experimentation framework across web and in‑product surfaces
  • Design, review, and debug experiments to ensure statistical validity and consistent user experiences
  • Apply Bayesian methods, sequential testing, and multi‑arm bandits to real product decisions
  • Establish best practices for experimentation design, analysis, and rollout
  • Act as the go‑to expert for causal inference questions across the product organization

Product Analytics & Modeling

  • Partner with Product, Engineering, and Design to answer complex questions around:
  • Feature adoption and usage
  • User success and expansion
  • Retention and churn drivers
  • Build and deploy analytical models that inform product strategy and prioritization
  • Translate ambiguous product questions into rigorous analytical approaches with clear recommendations

Technical Leadership & Coaching

  • Review analytical approaches and model implementations from other team members
  • Coach and mentor data scientists and analysts on advanced statistical techniques
  • Set the technical bar for experimentation and analytical quality within the team
  • Promote reproducible, well‑documented, and reviewable analytics work

Stakeholder Influence

  • Educate non‑technical stakeholders on experimentation, uncertainty, and decision‑making
  • Advocate for statistically sound practices in environments where experimentation maturity is low or fragmented
  • Build trust in data science outputs through clear storytelling and business‑aligned insights
  • Partner with leadership to define and prioritize the experimentation roadmap

Tooling & Infrastructure

  • Contribute to the evaluation and implementation of experimentation platforms and tooling
  • Work in a collaborative, code‑first environment using version control and peer review
  • Ensure analytics and experimentation workflows are scalable and reliable

Required Qualifications

  • 6+ years of experience in data science, product analytics, or related fields
  • Hands-on expertise in experimentation methodologies, including:
  • Bayesian analysis
  • Causal inference
  • A/B and multivariate testing
  • Sequential testing or multi‑arm bandits
  • Strong product analytics background within a SaaS or digital product environment
  • Proficient in Python and SQL
  • Comfortable working in Git-based workflows (PRs, code reviews)
  • Experience deploying or productionizing at least one analytical or ML model
  • Proven ability to connect technical work to business outcomes

Preferred Qualifications

  • Experience evaluating or implementing experimentation tooling
  • Exposure to user lifecycle analytics (activation, adoption, retention, churn)
  • Familiarity with modern analytics engineering or experiment platforms
  • Comfort working in ambiguous environments with evolving data maturity
