We are seeking a Lead MLOps Engineer to head an MVP engagement with a major AAA game publisher, building a test intelligence platform for two game franchises in parallel. A core design principle is full re-derivability and model lineage from day one — every run must be replayable from its stored configuration version and feed read positions. The signal catalog feeds a scoring strategy engine with versioned configurations, and calibration sweeps over historical data produce suggested weight updates surfaced directly in the Settings View.This role sets the technical direction for the ML and signal components, ensuring they are production-ready, reproducible, and improvable over time, forming the foundation of the system's long-term value as franchise history accumulates and models are refined.The Lead MLOps Engineer will define standards, mentor engineers, and act as the primary technical authority for all MLOps practices across both franchise workstreams.ResponsibilitiesDefine the overall MLOps architecture and strategy for the platform, establishing standards for reproducibility, lineage, and model lifecycle management across both franchisesOwn Signal Catalogue operations end-to-end: architect signal refresh orchestration triggered by feed read-position advances, define grain translation policies between per-test, per-area, and per-run signal families, and establish provenance capture standards across all 8 signalsSet the strategy for Semantic Vector Index versioning: partner with the Lead AI Developer on model and dimension stamp conventions; design and govern the controlled reindex path when the enterprise AI gateway model changesArchitect, deliver, and own the Back-test & Calibration Harness: as-of temporal filtering across all record families, replay runner, look-ahead spot audit, and configuration sweep runnerEstablish and enforce holdout patch-set discipline, define configuration sweep methodology over route limits, thresholds, weights, and Composition setting; oversee catch-rate vs.



scope analysis per candidate configuration and approve winning configurations as suggested-weight proposals into the Settings ViewLead Model Generation & Experimentation strategy: define the systematic experimentation framework over scoring strategy configurations, guiding the team on which signal weights and route combinations yield the best catch-rate vs. scope trade-offGovern model lineage across configuration versions for both franchises, ensuring cross-franchise consistency and auditabilityDesign and oversee the MLOps Monitor and Data-Health Monitor: catch-rate floor monitoring, run-behaviour drift counters (per-run candidate volumes per route, score distribution vs. usual range), data-health telemetry across all ingestion channelsDefine exploration cadence policy: unbiased random-sample injection with provenance ensuring exploration entries are never counted as model recommendationsAuthor and own operator runbook sections covering signal refresh, calibration campaigns, model generation runs, and embedding reindex proceduresMentor engineers on MLOps best practices, review technical designs, and represent the MLOps function in cross-team architecture discussions with data engineering, AI development, and product stakeholdersRequirements5+ years of experience in MLOps or ML platform engineering, with a proven track record of leading technical initiatives end-to-endDeep expertise in ML model lifecycle management, including versioning, configuration management, and rollback, with experience defining organization-wide standardsStrong background in architecting signal computation pipelines, covering scheduled refresh, provenance capture, and grain translationAdvanced proficiency in calibration methodology: holdout discipline, configuration sweep design,
