Staff Data Scientist (Product Analytics)

Role Overview

Join Headway as a Staff Data Scientist (Product Analytics). This senior technical and strategic role will help you own complex product questions, define success metrics, and drive cross-team decisions through rigorous measurement, experimentation, and evaluation systems.

Responsibilities

• Define and own product measurement strategy, align stakeholders on metric definitions, and establish what “good” looks like.
• Lead ambiguous, multi-team initiatives by driving cross-functional work when the answer isn’t obvious.
• Establish experimentation standards, including test design frameworks, safeguards, decision rules, and interpretation guidelines.
• Develop evaluation systems and build scalable analytical assets.
• Develop and mentor other data scientists and act as a thought leader.
• Translate insights into measurable outcomes, not only analyses.

Requirements

• Deep expertise in:
  • Bayesian experimentation
  • Causal inference
  • Measurement design (including common failure modes and how to prevent them)
• Expert proficiency in SQL and strong ability in Python or R, with experience building reliable, reusable analysis workflows.
• Strong applied modeling judgment (choosing when modeling is appropriate; validating and launching responsibly).
• Executive communication and influence: earn trust, align stakeholders, and move decisions forward.
• Track record of leading ambiguous, cross-team work and delivering measurable outcomes.

Nice-to-Haves / Additional Expectations

• 10+ years using data to drive product or business decisions (product, growth, engineering, or operations environments) or equivalent scope.
• Strong product sense and instinct for decision leverage (focus on what changes outcomes).
