# Senior Machine Learning Engineer

> Weekday AI · Mumbai, India · Full-time · Posted 2026-08-07

**Workplace:** on_site

**Department:** Weekday's Client via platform

## Description

**This role is for one of Weekday’s clients**  
  
Min Experience: 5+ years  
Location: Mumbai, Maharashtra, India  
JobType: full-time

This is a model-building role, not an ML platform or MLOps role. You'll be designing the statistical and machine learning models that sit at the core of our sports intelligence products — predictive models over live match data, and player and team performance metrics that are published, sold, and argued about by people who know the sport well.

## Requirements

**Responsibilities:**

\- Design, build, and validate predictive and descriptive models over live and historical sports data  
\- Define performance metrics and rating systems, and defend their methodology to product, commercial, and external stakeholders  
\- Own feature engineering and the analytical datasets your models depend on, working from the team's data marts  
\- Establish validation, backtesting, and monitoring practices appropriate to models whose outputs are published in real time  
\- Take models from prototype to production, working with data and backend engineers on serving and integration  
\- Investigate model failures and drift, and improve accuracy and robustness over time  
\- Translate domain questions from product and sports stakeholders into tractable modelling problems

**Requirements:**

\- 5+ years building statistical or machine learning models in production, with clear ownership of modelling decisions rather than only implementation  
\- Strong grounding in applied statistics: probabilistic modelling, regression, time-series or sequential data, and rigorous validation  
\- Strong Python and the standard modelling stack; strong SQL  
\- Demonstrated ability to work with large, messy, real-world event data  
\- Ability to explain and defend a model's methodology to a non-technical audience — a substantial part of this role is making a number credible, not just accurate  
\- Judgement about model complexity: knowing when a simple, explainable model is the correct answer

### Must-have skills

Python, SQL
