Role Description

As a Sr. Machine Learning Engineer at tvScientific, you'll build the ML and AI systems behind our Connected TV ad-buying platform: real-time bidding, campaign optimization, and incrementality measurement at scale.

• Write production Python that powers real-time bidding, model training, and campaign optimization
• Train, deploy, and monitor ML models that decide which ads to show, when, and at what price: millions of bid decisions per second
• Build and improve our incrementality measurement systems: helping advertisers understand the true causal lift of their CTV spend
• Design and implement new ML products across the ad-buying lifecycle: audience targeting, bid optimization, pacing, and attribution
• Use LLMs and generative AI to build internal tools that accelerate how we develop, test, and ship ML systems
• Serve as a technical lead and mentor on a distributed engineering team

Qualifications

• Strong production Python skills: you write code that runs in prod, not just notebooks
• Solid statistics and ML fundamentals: you can reason about experiment design, model evaluation, and when simpler approaches beat complex ones
• Familiarity with modern AI tools and good judgment about where they add value
• Adtech or CTV experience: familiarity with RTB, programmatic advertising, supply-path optimization
• Clear written communication: we're a distributed team and writing is how decisions get made
• Comfort with ambiguity: you'll own problems end-to-end in a fast-moving environment, from scoping to shipping

Requirements

• Teaching experience
• Causal inference: uplift modeling, synthetic controls, difference-in-differences, or incrementality testing
• Big data experience with Scala and Spark
• Systems programming experience in Zig or similar (C, C++, Rust)
• Reinforcement learning or bandit algorithms in production
• Experience building agentic AI systems or LLM-powered workflows
• MLOps experience: model deployment, monitoring, and pipeline orchestration on AWS
