Sirector Data Scientce - GTM Strategy & Predictive Analytics

United States | New York

$230,000 - $250,000 base + $25,000-$75,000 bonus

Harnham is partnering with a highly regarded GTM strategy consultancy that works with some of the world's most sophisticated B2B organisations across SaaS, enterprise technology, and Private Equity portfolios.

They are hiring a Data Science Lead to sit at the heart of client delivery - owning predictive modelling, setting analytical standards, and acting as a trusted advisor to senior commercial leaders.

This is a senior, hands‑on "player‑coach" role for someone who combines consulting‑grade communication, deep statistical modelling expertise, and a strong understanding of go‑to‑market, sales, and revenue problems.

The Role

You will split your time across client delivery, technical leadership, and methodology development, including:

  • Leading complex predictive analytics workstreams across GTM use cases (segmentation, targeting, churn, forecasting, pricing, quota optimisation, marketing effectiveness)
  • Acting as the quality bar for modelling and statistical rigor across the team
  • Translating analytical outputs into clear, executive‑ready recommendations
  • Leading and guiding a team of data scientists (7-10)
  • Developing reusable analytical frameworks and IP
  • Supporting business development as a technical expert (no independent selling)

This role is delivery‑led - you will be directly involved in the most complex client problems while advising across the broader portfolio.

What We're Looking For

This role has no room for weaknesses in the core areas below:

Consulting & Communication (Non‑negotiable)

  • Polished, confident communicator
  • Comfortable on senior client calls
  • Able to explain modelling choices and trade‑offs without over‑engineering

Predictive Modelling & Statistics

  • Strong Python (pandas, scikit‑learn, stats libraries)
  • Proven experience with regression, classification, clustering, forecasting, experimentation, causal methods
  • Solid statistical foundation (maths, statistics, economics or similar undergrad strongly preferred)
  • R experience is a plus

Commercial / GTM Domain Expertise

  • Hands‑on experience with GTM, Sales, RevOps, Marketing or Revenue Analytics
  • Familiarity with CRM, pipeline, account‑level and marketing data
  • Able to connect modelling decisions directly to revenue impact

Background

  • 4-10 years in data science / analytics
  • Experience in consulting, PE value creation, financial services analytics, or high growth B2B environments
  • Prior leadership or player‑coach experience required

Why This Opportunity

  • Shape and scale a growing data science capability
  • Work on high‑impact commercial problems, not product feature optimisation
  • High visibility with senior consulting and client leadership
  • Entrepreneurial, intellectually rigorous environment

If you are a consulting‑grade data science specialist who enjoys solving commercial problems with statistical rigour, this is a rare opportunity.
