Machine Learning Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Machine Learning Engineer based in United States. This role offers the opportunity to build and operate machine learning systems that directly influence real-time business decisions at significant scale. You will develop production-grade models while helping advance the technologies used to train, serve, monitor, and improve them. The position combines hands-on machine learning engineering with research exploration, pipeline optimization, and model performance management. You will work alongside experienced engineers and contribute to an engineering culture focused on rigorous testing, explainability, code quality, and continuous improvement. Your work will span large-scale recommendation systems and deep learning applications, with opportunities to explore emerging ML techniques. This is a remote-first position offering meaningful technical impact within a distributed, collaborative engineering environment.

Develop, deploy, and maintain machine learning models that support production decision-making systems and directly influence business outcomes. Build or adopt technologies that improve the training and serving of machine learning models, including solutions capable of supporting large models and increasing developer productivity. Monitor current machine learning research and identify promising techniques that can be evaluated and applied to practical business challenges. Design, build, and scale efficient machine learning pipelines for both real-time and batch processing. Monitor model performance, identify data or model drift, and develop automated retraining and improvement processes. Apply deep learning and neural network techniques to large-scale production systems, including recommendation systems. Collaborate with engineers from diverse technical backgrounds to design reliable and scalable solutions. Communicate statistical and machine learning concepts clearly to both technical and non-technical stakeholders. Contribute to engineering excellence through state-of-the-art development tools, risk-driven testing, explainable systems, and rigorous code review. Drive projects from technical planning through execution and timely delivery while continuously improving engineering and machine learning practices. Requirements: 6+ years of industry experience applying machine learning, including neural networks, to large-scale problems. Strong hands-on experience developing and operating deep neural networks in production at scale. Experience designing or working with recommendation systems. Solid software engineering and coding capabilities with an emphasis on building reliable production systems. Demonstrated ability to execute projects effectively and deliver high-quality results within expected timelines. Strong analytical and problem-solving skills, with an ability to evaluate multiple approaches and focus on the most effective solution. Collaborative mindset and willingness to set aside personal preferences in pursuit of the strongest technical outcome. Bachelor’s degree or higher in Machine Learning, Mathematics, Physics, or a related technical discipline. PhD in a relevant field is a plus. Experience in AdTech or related advertising technology environments is a strong plus. Strong written and verbal communication skills, particularly when explaining complex machine learning and statistical concepts. Benefits: Base salary of $225,000–$275,000 for the San Francisco Bay Area, Los Angeles/Orange County, NYC, and Seattle.
