This team has full ownership of Adikteev's ML ecosystem, building and maintaining the systems that power the core of our business at massive scale. They operate with a strong product ownership mindset, working at the intersection of research and production, where the models they ship have a direct and measurable impact on billions of real-time decisions every day.

WHAT YOU WILL DO

• Team Leadership: Lead, grow, and manage the Machine Learning team, setting technical direction and priorities while directly managing and mentoring ML engineers, including senior+ profiles.
• Model Development: Design and train predictive models for CTR, CR, VTA, bid shading, and auction-win probability across display and video inventory.
• Platform Engineering: Scale our ML platform, feature stores, training pipelines, model versioning, A/B experimentation, to support multiple model families running in production simultaneously.
• Real-time Systems: Drive sub-10ms inference at high QPS through model optimization (ONNX), efficient serving, and latency-aware architecture decisions, informed by hands-on DSP/RTB experience.
• MLOps & Observability: Own end-to-end ML workflows from data ingestion through monitoring: drift detection, shadow scoring, A/B tests, and automated retraining triggers; drive design reviews, ADRs, and mentoring of the team. Translate business objectives into technical strategies.
• Cross-functional Partnership: Work closely with Tech, Reporting, Product and Analytics teams to define ML KPIs, instrument experiments, and communicate model performance to stakeholders up to Comex level.
• Applied Research: Design and set up a neural network for adtech from the ground up, taking it from prototype to production in our bidding stack.
