About Us
Betty is an innovative entertainment company pioneering at the intersection of real-money online casinos and casual mobile gaming.
Betty Canada is a scale up company accredited by the Alcohol and Gaming Commission of Ontario (AGCO) as a B2C operator in February 2023, we've set a new standard in the industry.
Our mission is to redefine the online casino experience by offering a uniquely transparent environment where players can relax, unwind, and enjoy themselves safely. We are committed to accessibility, fairness, and inclusivity, fostering a community of like-minded individuals who value ethical gaming practices and prioritize our players' safety and enjoyment above everything else.
Our Values
- We are honest: we value honesty in all aspects.
- Bring the Olives: we offer premium customer experience.
- Think Big: we believe in always striving for more.
Key responsibilities
- Design, build and ship AI solutions based on LLMs, such as AI agents, retrieval-augmented generation (RAG) and automated analysis and reporting, that teams across the business use every day.
- Help shape how Betty adopts AI: find high-value use cases, evaluate models and tools, and set up checks that AI outputs are accurate, reliable and cost-effective.
- Partner with the marketing and user acquisition teams on channel and campaign performance, using metrics such as CAC, ROAS, CPA, first-time depositors (FTDs), conversion rates and predicted LTV.
- Build marketing models such as predicted LTV for newly acquired players, attribution, marketing mix modeling, incrementality measurement and budget allocation across channels.
- Work with analysts, marketing, product and business stakeholders to turn business questions into clear requirements, success metrics and use cases.
- Work with large event-level data in Redshift, and combine and clean data from internal and external sources such as player activity, transactions, payments, CRM and marketing platforms.
- Build statistical and machine learning models for problems such as player lifetime value, churn and retention, segmentation, forecasting and driver analysis.
- Form and test hypotheses about player and commercial behavior, and turn the answers into clear recommendations, including how they affect our players.
- Find opportunities and inefficiencies across player segments, games, providers, payment flows and channels, and run deep-dives that support product launches and marketing campaigns.
- Support experimentation and A/B testing: define success metrics, analyze results and know when a result is real.
- Take models from prototype to production and own them end to end, from batch jobs on daily, weekly and monthly schedules to real-time inference where speed matters.
- Build and run real-time pipelines that stream player events (for example with Kafka or Flink), compute features on live data and serve predictions with low latency, such as real-time churn and retention signals.
- Set up the MLOps foundations: CI/CD for models, model registry and versioning, a feature store, automated retraining, and monitoring for drift, data quality and model performance.
- Present results through dashboards and clear recommendations to any audience, up to C-level.
- Help other teams use data and AI on their own, through self-service analytics and shared environments where they can safely deploy their own AI tools.
- Work within the rules of a regulated market, including responsible gambling and data privacy requirements.
Requirements
- 3+ years of experience as a Data Scientist/ML Engineer.
- Strong knowledge of statistics and machine learning methods, such as predictive modeling, classification, clustering, regression, and optimization.
- Advanced Python with strong software engineering practices (testing, code review, Git), and advanced SQL with Redshift or a comparable cloud data warehouse.
- Proven experience deploying and running ML models in production, including CI/CD, containers (Docker), model versioning, automated retraining and monitoring for drift and performance.
- Hands-on experience building solutions with LLMs and generative AI, such as retrieval-augmented generation (RAG), AI agents and tool use, prompt engineering and NLP.
