This allows our company culture to be defined by our team members and their shared values, like trust, ambition, quality, radical honesty, and compassionate leadership. It’s why we all really love working for the Hardest Working Software in Television™ (and also why we were named one of Ad Age’s Best Places To Work in 2026.)\nWe pride ourselves on bringing unrivaled performance and simplicity to Connected TV advertising. Our self-serve technology makes running TV ads as easy as search and social, helping brands drive measurable conversions, revenue, site visits, and more. It’s what led MNTN to being named one of Fast Company's Most Innovative Companies in 2023. You can learn more about us and everything we do by visiting https://mountain.com/.\nWe’re committed to innovation that empowers, not replaces. At MNTN, AI is a tool for growth, enhancing efficiency while keeping a people-first approach. Our goal is to streamline workflows and drive new solutions-without compromising the human element that makes our company great.\nSo if wanting to do more, own more, and make a bigger impact comes naturally to you, then you may be the person we're looking for to join us in our next stage of growth.\nThe MNTN Media Buying Intelligence team helps brands reach the right customers with software that turns petabytes of data into meaningful campaign strategies. Our engineers, data scientists and analysts build software that serves content to millions of people every day. \nAs a Senior Machine Learning Engineer, you will focus on operationalizing machine learning models by taking ownership of prototypes built by data scientists and turning them into robust, scalable production systems. You will lead the deployment, monitoring, and maintenance of ML solutions that power campaign optimizations at scale. This role emphasizes strong software engineering practices, designing for reliability and performance, and working with large-scale data pipelines and infrastructure. You’ll collaborate across functions to ensure models are not just accurate but production-ready, scalable, and cost-effective. This is a senior machine learning role with an emphasis on building production-ready models. It is not a pure research role. You are expected to ship production-grade implementations and own outcomes in production.\nWhat You’ll Do:\nDesign and build a robust marketing platform that reaches the right audience, anywhere and anytime\nBuild high-volume services that remain reliable at scale\nDevelop big data solutions using open-source frameworks\nDesign, train, evaluate, and improve models for deliverability, forecasting, and optimization\nImprove model quality by refining thresholds, calibration, and guardrails to reduce false positives and decision noise\nBuild offline and online evaluation workflows tied to measurable business outcomes, enabling faster testing and more confident releases\nPartner with Product, Project Leads, and platform-focused Machine Learning and Data Engineers to improve service reliability, latency, observability, and data freshness\nShare ownership of production systems, including shipping model improvements safely and participating in the on-call rotation\nWhat Success Looks Like:\nModel quality improves on agreed business and operational metrics.\nFalse positives,unstable decision behavior, and other secondary metrics are reduced in key flow.\nModel testing/evaluation cycles become materially faster, better, and more performant.\nMore product testing and analysis\nMore model improvements reach production safely and predictably.\nWhat You’ll Bring:\n5+ years building ML models that were deployed and operated in production.\nExtreme Proficiency in technical communication to nontechnical stakeholders.\nExcellent applied ML fundamentals (classification/regression/forecasting + evaluation rigor)\nStrong optimization understanding in business context\nStrong Python and SQL with production engineering discipline (testing, maintainability, performance).\nExperience balancing model quality, system constraints, and speed-to-production.\nStrong experience with ownership and cross-functional collaboration.\nExperience in ad tech, growth analytics, personalization, or performance marketing\nProficiency working with real-time or near-real-time data pipelines\nExperience with experimentation frameworks and production model monitoring.\nExperience large scale data processing and ML systems such as: Kedro, AutoGluon, PyTorch, Polars, BigQuery/GCP, Airflow/SQLMesh, and Databricks ecosystems.\nExperience in Reinforcement Learning such as Q-Learning or Multi-Armed Bandits is a plus.\nAbout MNTN\nOur recruiters will always reach out using an email address ending with @mountain.com OR @mntn.com. If you’re contacted by someone without that address and they mention a Reference Code (which we never use), then that ain’t us folks.
