Type: Remote, Full-time
About the role
Turn audience science into scalable production systems that help advertisers decide whom to reach. Working with terabyte-scale data, you'll build, score, refresh, and deliver audience segments to activation endpoints across DSPs, clean rooms, CTV, social, and programmatic partners. You bridge data science and platform engineering—converting prototypes into production-grade services and owning the pipelines, MLOps, and integrations behind them. As a senior team member, you'll set engineering standards, lead end-to-end system design, and mentor other engineers. Stack: Databricks, Spark, Snowflake, and Azure.
Responsibilities
Convert data science prototypes (propensity, lookalike, segmentation, fusion) into reproducible, production-quality ML services.
Build and operate large-scale data/feature pipelines on Databricks + Spark, reading from and writing to Snowflake, producing versioned audience segments on schedule.
Own the full model lifecycle: MLflow tracking/registry, CI/CD (Azure DevOps or GitHub Actions), automated retraining, drift monitoring, and rollback.
Engineer the activation layer, governed delivery of segments and scores into DSPs/SSPs, DMP/CDP, clean rooms, and CTV/social/programmatic partners, including identity resolution and onboarding.
Ensure scalability, latency, cost-efficiency, and reproducibility across Azure (ADLS, Azure ML, AKS); support batch and near-real-time scoring.
Enforce privacy-by-design: data minimization, access controls, encryption, and clean-room-compatible patterns.
Essential qualifications
8–9 years hands-on ML engineering, shipping and operating production systems at scale.
Prior experience in media / advertising / audience activation.
Databricks (incl. MLflow and Spark), Snowflake, and production Azure (ADLS, Azure ML, Azure DevOps, AKS).
Expert Python and ML ecosystem; strong SQL at scale.
Strong applied statistics (sampling/weighting, forecasting, causal inference, or experimental design).
CS/engineering degree with strong quantitative foundations.
Desirable
Agile practices, Docker/Kubernetes, advanced Databricks/Snowflake (Structured Streaming, tuning, Model Serving/Feature Store), orchestration (Databricks Workflows, Airflow, Dagster).
Ad tech/identity experience: DSP/SSP, DMP/CDP, clean rooms (LiveRamp, Snowflake), identity graphs, onboarding, delivery APIs.
AWS/GCP a plus.
About you
Pragmatic and deeply hands-on about production trade-offs; a clear communicator with non-expert stakeholders; a proactive team player who mentors others. Comfortable working the second half of the day to overlap with a US-based product team. Fluent in an English-language business environment.
