You will own the end-to-end architecture, build pipelines, systems, and models, and scale a cross-disciplinary team of engine developers, game developers, and machine learning engineers. The work spans market forecasting, outcome prediction, multimodal content understanding, evaluation, and agentic systems.\nWhat you'll be doing\nTechnical leadership\nSet the technical vision and architecture for our ML platform, from data ingestion, semantic layer and feature stores through model registry, evaluation and serving.\nMake the calls that keep every model output reproducible and auditable: versioned data snapshots, model and prompt versions, and cost tracked per decision.\nDefine, lead, and spearhead engineering practices for the agentic era, including agentic development workflows and evaluation methodologies.\nMentor engineers from different backgrounds.\nPartner with different functional teams and disciplines to translate expert human judgment into training signals. Shape the roadmap with the product team.\nModeling\nBuild predictors of commercial outcomes such as user acquisition cost, lifetime value and return on ad spend from large, noisy, multi-source signals.\nBuild forecasting models over market signals that detect emerging demand and estimate when a window opens, peaks and closes.\nDeliver every prediction as a calibrated range with stated confidence, and own the ranking and portfolio logic that turns predictions into recommendations within a budget.\nExperimentation and agentic systems\nDesign online experimentation with guardrails, safe exploration and clear human decision points.\nBuild evaluation harnesses for LLM-based agents, including automated playtesting and multimodal assessment of generated content.\nOrchestrate frontier-model agents in production with strict data boundaries and cost control.\nCalibration and measurement\nOwn the feedback loop that scores predictions against realized outcomes and corrects bias, coverage and signal weighting over time.\nMake the system report its own error in plain language so that creators and internal stakeholders can trust it.\nWhat we're looking for\nExperience in machine learning with a track record of owning production ML systems end to end, from data to serving to measured business outcome.\nDeep experience in performance marketing or ad-tech modeling: predicting acquisition cost, lifetime value, return on ad spend, retention or comparable outcomes.\nStrong grounding in probabilistic prediction and calibration: quantile or interval prediction, coverage, bias correction and backtesting of forecasts.\nExperience building LLM-based agent systems in production: orchestration, evaluation harnesses, prompt and model versioning, and cost control.\nStrong Python and modern ML tooling, plus solid data systems fundamentals across a relational store, a columnar analytics store and an event stream.\nProven ability to drive technical direction across teams, mentor senior engineers, and influence decisions without formal authority.\nComfort building in a zero-to-one environment.\nYou might also have\nExperience in mobile game user acquisition, LiveOps or monetization, on the studio or publisher side.\nExperience with Unity or another game engine, or with automated and bot-driven playtesting.\nTime-series and demand forecasting experience over noisy, multi-source market signals.\nExperience with the Claude Agent SDK, Codex or similar frameworks for multi-agent software production.\nHands-on experience with BigQuery, ClickHouse, Kafka, Postgres, pgvector or their equivalents.\nPublications or open-source contributions in forecasting, causal inference, calibration or agentic systems.\nBase Salary Range: We determine the base salary range for this role based on your primary work location:\nZone A: $218,400 - $283,900\nZone B: $194,100 - $252,300\nZone C: $172,200 - $223,900\nThis range reflects the anticipated base salary for this position.
