About The Position

The Staff Data Scientist, Forward Deployed, leads technical work for strategic customer engagements, partnering directly with customer teams to tailor predictive models to their go-to-market needs and improve pipeline results. The role sets technical direction across multiple engagements while remaining hands-on, and brings learnings from customer work back into the product. The position works with customer marketing and revenue operations teams to understand their data, goals, and go-to-market strategies; adapts and optimizes predictive models; and guides engagements from discovery through production. It also turns recurring customer solutions into reusable patterns and product roadmap input, establishes team standards, and mentors data scientists.

Requirements

  • 10+ years building and deploying machine learning models in production, ideally supervised models on tabular or behavioral data such as propensity, scoring, or ranking.
  • Experience working directly with customers on their data through consulting, client-site work, or a forward-deployed or solutions role.
  • Strong applied machine learning fundamentals, including tree-based models such as XGBoost and Random Forest, feature engineering, evaluation, calibration, threshold setting, and critical interpretation of metrics.
  • Experience owning production model changes end to end, including backtesting, promotion decisions, and rollback.
  • Fluency in Python and SQL.
  • Comfort working with messy, fragmented customer data rather than only clean benchmarks.
  • Ability to run multiple engagements concurrently and switch between them without a fixed sprint plan.
  • Exceptional communication skills, including explaining work to executives and engineers.
  • A product mindset, with a preference for building capabilities reusable across customers rather than repeatedly solving the same problem by hand.

Nice To Haves

  • Experience with B2B go-to-market data, such as CRM, marketing automation, intent, ABM, or predictive scoring.
  • Experience explaining model output to non-technical users.
  • Experience leading a small team or a portfolio of client engagements.
  • Experience building or evaluating LLM-based tools and agents.
  • Experience with data platforms such as SingleStore, Hive, or Spark on AWS.

Responsibilities

  • Lead the technical side of strategic customer engagements from discovery through production deployment.
  • Partner with customer marketing and revenue operations teams to understand their go-to-market strategies, data, and goals, and identify opportunities for predictive intelligence.
  • Tailor and optimize customer models, including ideal customer profiles, industry definitions, keyword and intent strategies, CRM and marketing automation activity inputs, and score thresholds.
  • Shape engagement scope, plans, estimates, and success measures with Professional Services and Customer Success.
  • Lead customer reviews recommending next models, supported by backtests and conversion analyses that customers can verify using their own data.
  • Communicate the work and its results in language appropriate for business leaders and practitioners.
  • Guide customers through model and configuration changes and explain their expected effects.
  • Turn successful approaches into reusable patterns and provide recurring patterns to Product as roadmap input backed by field evidence.
  • Set team standards for discovery, validation, documentation, and handoff.
  • Mentor the team's data scientists.
