ABOUT YOU

We are seeking a Machine Learning Engineer who is a thinker and a hands-on problem solver that bridges the gap between business and data. You are skilled at translating business constraints and applying the best models to achieve optimal monetization for our partners. You will collaborate with cross-functional teams, including product managers and ad operations, to understand requirements, define objectives, and deliver impactful solutions. Adept in statistical modeling, machine learning, and data storytelling, you ensure that insights are not just technically sound but aligned with real-world business needs. While you will have data engineer partners, you are self-sufficient and able to develop models end-to-end and put them into production.

RESPONSIBILITIES

• Leads and supports multiple Machine Learning projects, ensuring alignment with business objectives and data needs.
• Oversees the Kanban process for managing ML model development, deployment, and maintenance.
• Engages in technical discussions both within the company and with external data partners, fostering collaboration and knowledge sharing.
• Drives the design and architecture of machine learning solutions by deeply understanding data usage and identifying opportunities to integrate new data sources.
• Implements emerging technologies and methodologies in machine learning, ensuring state-of-the-art solutions and continuous innovation.
• Mentors and guides junior ML engineers, promoting best practices, scalability, and efficiency in model development.
• Collaborates closely with data engineers and scientists to enhance ML workflows, ensuring models are reliable and production-ready.

REQUIREMENTS

• Strong proficiency in ML frameworks and libraries such as TensorFlow, PyTorch, Scikit-Learn, XGBoost, and deep learning architectures.
• Experience with cloud platforms (AWS, GCP, Azure) and deploying ML models using SageMaker, Vertex AI, or Azure ML.
• Familiarity with MLOps practices, including model versioning, CI/CD pipelines for ML (e.g., MLflow, Kubeflow, Airflow), and monitoring deployed models.
• Expertise in data preprocessing and feature engineering, using tools such as Pandas, NumPy, and Apache Spark.
• Strong programming skills in Python (preferred) or Scala, with experience in containerization tools like Docker and Kubernetes.
• Understanding of distributed computing and parallel processing frameworks such as Ray or Dask for scalable ML workloads.
• Experience in deploying ML models to production, optimizing inference latency, and ensuring model robustness in real-world applications.

NICE TO HAVE

• Experience in data pipelines and analytics for video-game development.
• Experience in the Advertising industry.
• Experience in online businesses where transactions happen without human intervention.
