Data Scientist, Product

The role

You will build models for churn, retention, and lifecycle propensity to drive user actions. You will own uplift modeling, lifetime value calculations, and experimental design to measure the monetary value of campaigns.

What you will do

• Build churn and downgrade prediction for subscribers and repeat-purchase propensity for one-time credit-pack buyers
• Own incrementality for discounts, credit vouchers, trials, upgrade prompts, win-back campaigns, and retention saves
• Design randomized holdouts to make uplift trainable and measurable
• Own LTV based on contribution margin and split by plan, segment and acquisition discount
• Model refunds, chargebacks, credit breakage, plan migration, and compute consumption
• Design and read experiments behind pricing, packaging, offers and lifecycle
• Own work end to end from framing decisions and training to monitoring and retraining
• Monitor models for drift caused by new launches, price changes, or seasonality
• Write down what each model is worth in money

Required qualifications

• Experience shipping models that changed what the business did to real users
• Depth in at least two of: churn and propensity modelling, uplift & causal ML, LTV and subscription economics, experimentation at scale
• Genuine causal literacy: randomized holdouts, incrementality, Qini and uplift curves, selection effects
• Strong SQL and Python
• Understanding of subscription plus one-time purchase mechanics
• Commercial judgment
• Pragmatism
• Clear written and spoken English, B2+

Nice to have

• Growth, retention or monetization data scientists from subscription, gaming, fintech or e-commerce
• CRM and lifecycle data scientists who owned campaign targeting and its incrementality
• Causal inference and uplift specialists who ship policies rather than papers
• Strong product analysts who moved into modelling and kept the decision instinct

Benefits

• Equity participation through the company's stock option program
• Relocation support to Almaty
• Highly collaborative, fast-paced environment
• Opportunities for professional growth, ownership, and career development
• Company-provided equipment
• Meals

• Other office benefits

Before you apply

• Screening call (30 min)
• Technical interview & case study (1 hour)
• Practical home task (7 days)
