Machine Learning Engineer

Accountabilities:: Develop, deploy, and maintain machine learning models that support large-scale production decision-making and directly influence business outcomes. Build or adopt technologies that improve the training and serving of machine learning models, including solutions that support larger models and increase engineering productivity. Research emerging machine learning techniques and evaluate opportunities to apply relevant advances to production systems. Design, optimize, and scale efficient machine learning pipelines for both real-time and batch processing. Monitor model performance, identify data or model drift, and implement automated retraining and improvement processes. Apply strong software engineering practices to create reliable, maintainable, and scalable machine learning systems. Collaborate with engineers and cross-functional stakeholders to translate technical and statistical concepts into practical solutions. Contribute to an engineering excellence culture through rigorous testing, code reviews, explainable systems, and modern development tools. Communicate complex machine learning concepts clearly to both technical and non-technical audiences. Requirements: 6+ years of industry experience applying machine learning, including neural networks, to large-scale production problems. Strong experience with recommendation systems and their application in production environments. Hands-on experience developing and deploying deep neural networks at scale. Solid software engineering and coding skills with the ability to build robust production systems. Demonstrated ability to execute complex projects effectively and deliver results on time. Strong collaborative mindset and willingness to evaluate ideas based on their technical merit rather than individual ownership. Bachelor’s degree or higher in Machine Learning, Mathematics, Physics, Computer Science, or a related technical field; a PhD is a plus. Experience in AdTech or mobile advertising technology is highly desirable. Strong written and verbal communication skills, with the ability to explain statistical and machine learning concepts to diverse audiences.
