Senior Machine Learning Engineer

LEAD ML ENGINEER

Blue Ash, OH | 8 - 15 years of experience

We are seeking a Lead ML Engineer with strong expertise in Python, Machine Learning Engineering, MLOps, Azure Cloud, Spark, MLflow, and CI/CD automation. The ideal candidate will lead the development and deployment of production-grade ML solutions, build scalable ML platforms, implement model monitoring and governance, collaborate with Data Engineering and Cloud teams, and mentor ML engineers. Experience with Databricks, Azure DevOps/GitHub Actions, feature engineering, model lifecycle management, and cloud-native ML deployments is highly preferred.

REQUIRED SKILLS

• Languages: Python (required); SQL; optional Java/Scala
• ML/MLOps: MLflow (or equivalent), model registry, monitoring, evaluation pipelines
• Data: Spark, DataFrames, data modeling fundamentals, feature engineering
• DevOps: Git, CI/CD, Docker; Kubernetes, Terraform (optional)
• Cloud: Azure, logging/monitoring
• Experience with MLOps practices, including model versioning, monitoring, and CI/CD for ML pipelines.

GOOD TO HAVE

• Understanding of Data Science models
• Exposure to Deep Learning frameworks such as TensorFlow or PyTorch
• Solid understanding of feature engineering, model evaluation, and experimentation.

PREFERRED TRAITS

• Strong communication and storytelling skills with data
• Ability to work in a collaborative and fast-paced environment
• Passion for solving complex business problems using data

Roles & Responsibilities

ML Engineering & Delivery

• Lead the design and implementation of production ML pipelines for training, batch inference, and real-time/near-real-time scoring.
• Translate Data Science prototypes into robust, maintainable services and workflows with strong testing, observability, and reliability.
• Build and manage feature engineering workflows, feature stores (where applicable), and reusable ML components.
• Drive model packaging and deployment patterns (containers, serverless, managed endpoints) and optimize for performance and cost.

MLOps

• Implement CI/CD for ML (model versioning, automated testing, promotion gates, rollback strategies) using Azure DevOps / GitHub Actions integrated with Databricks
• Leverage MLflow (Databricks native) for experiment tracking, model registry, and lifecycle management
• Establish best practices for model monitoring: data drift, concept drift, model degradation, and alerting.
• Define and enforce guardrails for responsible AI: bias checks, explainability, privacy controls, and auditability.

Data & Platform Collaboration

• Partner with Data Engineering on data quality, lineage, and availability to ensure reliable model inputs.
• Work with Cloud/Platform teams to ensure scalable infrastructure (compute, networking, IAM, secrets, logging).
• Influence target architecture and technology decisions for the ML platform roadmap.

Leadership & Mentoring

• Provide technical leadership and mentorship to ML Engineers and junior team members.
• Conduct design reviews, code reviews, and establish engineering standards.
• Coordinate delivery plans, estimate work, and manage technical risks and dependencies.
