Requirements

• 5+ years of applied ML experience with structured business data in production.

• Strong foundations in mathematics and statistics from a rigorous academic programme. An IIT or a similarly strong programme is preferred.

• Experience owning a production model used for business decisions, such as churn, retention, propensity, customer health, or segmentation.

• Strong understanding of classification, precision, recall, fixed test sets, and time-based evaluation.

• Ability to identify and fix data leakage, incorrect labels, and weak features.

• Experience working with messy CRM and product-usage data.

• Strong SQL skills and the engineering ability to ship changes inside a product codebase.

• Ability to work with Go application code. Python can be used for analysis, but improvements must reach production.

• Experience investigating individual prediction errors and explaining them to people without an ML background.

• Ability to independently drive unclear problems through investigation, testing, and implementation.

• A public GitHub profile, side project, or technical blog is a strong plus.

• Candidate currently working at a product based organisation is a must.

Responsibilities

• Improve existing churn, retention, and account segmentation models using customer data.

• Evaluate predictions against actual renewal, churn, expansion, and adoption outcomes.

• Build time-based backtests that prevent models from accessing future information.

• Investigate incorrect predictions account by account and identify gaps in labels, features, or source data.

• Ship improvements into the existing Go product, rather than stopping at analysis notebooks.

• Explain model performance and prediction errors to customers in clear business terms.

• Keep internal queries and training datasets confidential when discussing results.

• In the first 30 days, run recall analysis for every existing customer using fixed test sets and ship improvements identified through that analysis.

• Within 3–6 months, automate evaluation and flag drops in recall, label quality, or product-usage signals before customers report them.

• Build and validate new models for expansion, cross-sell, forecasting, and marketing use cases.

• Work with the Principal Backend Engineer, owning prediction quality while they own the surrounding product.
