* Collaborate with data scientists to productionize Machine Learning models, ensuring seamless integration into our flagship product.
* Implement and optimize data preprocessing, feature stores, and retraining pipelines to keep models accurate and adaptive.
* Leverage Python, AWS, and Temporal to create robust, cloud-native solutions tailored to Real-Time and batch processing needs.
* Ensure data quality, scalability, security, and performance across all systems, from raw inputs to model outputs.
* Drive the adoption of MLOps best practices, including CI/CD for ML, model versioning, and automated retraining workflows.
* Troubleshoot and resolve complex issues in production AI/ML systems, ensuring reliability and efficiency.
* Evaluate and integrate cutting-edge tools, frameworks, and methodologies to enhance our AI infrastructure.
Requirements: What It Takes - Must haves: 5+ years of combined experience in data engineering, ML engineering, and/or MLOps, with a proven track record of building production AI/ML systems.
* Expert-level proficiency in Python and software engineering principles (e.g., modular design, testing, optimization).
* Extensive hands-on experience with AWS (e.g., S3, Lambda, ECS, SageMaker) and cloud-native architectures.
* Deep expertise in data pipelines, ETL processes, and feature engineering for Machine Learning.
* Strong knowledge of relational (e.g., PostgreSQL) and NoSQL databases, data warehouses, and feature stores.
* Experience with ML frameworks (e.g., TensorFlow, PyTorch, Scikit-learn) and deploying models in production.
* Proficiency in orchestration tools (e.g., Temporal, Airflow) and building scalable workflows.
* Solid understanding of CI/CD pipelines, containerization (e.g., Docker), and infrastructure-as-code principles.
* Expertise in data validation (e.g., Great Expectations) and testing frameworks (e.g., Pytest). Advantages
* Experience with Temporal for workflow orchestration or similar tools (e.g., Flyte, Argo).
* Familiarity with modern data stack tools (e.g., DBT, DuckDB) and stream processing (e.g., Kafka, Flink).
* Hands-on experience with MLOps platforms (e.g., MLflow, Kub
This position is open to all candidates.
