You’ll address business problems across product, support, acquisition, retention, fraud/risk. You’ll lead initiatives from the concept, mentor engineers, and collaborate across product and analytics to unlock high‑impact AI in gaming.
This role isn't just about building models it's about crafting intelligent systems that learn from player behavior and adapt over time.
Key Responsibilities:
ML Strategy & Ownership: Lead ML solutions for high‑impact gaming use cases—player segmentation, fraud & collusion detection, recommendations, and personalization during live play.
Research & Prototyping: Track emerging research; prototype new ML/LLM techniques; run internal experiments to assess value in gaming environments.
Model Development: Build models on large‑scale player data; deliver reproducible training code & inference artifacts; define quality criteria and ROI evaluation.
Team Leadership: Lead technical discussions, mentor senior ML engineers, conduct code reviews, define standards, and drive adoption of engineering best practices.
CrossFunctional Impact: Collaborate closely with product managers, backend teams, and analytics leads to align ML work with measurable business goals.
Reusable ML Solutions: Drive best practices in reproducible modeling, version control, and interpretability.
Champion AI Innovation: Share demos, run workshops, and promote continuous learning across teams.
