Senior Machine Learning Engineer - Esports (m/f/x)

• Are you excited about building ML systems that make predictions in real-time?

• Are you driven by building things end-to-end, from research to live systems?

If the answers to the above questions are yes, then this role could be ideal for you!

We are building real-time prediction systems for competitive esports (CS2, Dota2, League of Legends). Our models power live betting markets, producing continuously updated win probabilities, handicap lines, over/under totals, and specialty markets during matches.

We are looking for a Senior ML Engineer to own the full lifecycle of our prediction models: from research notebooks to production-grade ML pipelines, deployed at scale in a real-time microservices architecture.

Requirements

What you will do

• Convert existing model training code into reproducible, automated pipelines (experiment tracking, model versioning, automated retraining), following ML best practices

• Work on algorithms and probabilistic market-derivation logic that powers our live predictions

• Define evaluation metrics, build backtesting frameworks, and monitor model performance in production

• Serve models via a Python microservices stack

• Work with the product team to define new betting markets and the statistical models that support them

Your skills will include

• 5+ years of professional experience in ML engineering or applied data science

• Experience developing production-grade ML pipelines and are familiar with workflow orchestration, experiment tracking and CI/CD for ML

• Knowledge of object-oriented programming, using vector operations for optimized performance, and a deep understanding of memory management

• A strong grasp of probability and statistics

Nice to have

• Experience with real-time / streaming ML, models that update or serve live predictions

• Familiarity with betting / trading / quantitative finance, understanding of odds, overround, market-making, or any domain where calibrated probabilities matter

• Experience building MLOps infrastructure

• Knowledge of esports or sports analytics
