About This Opportunity

We are seeking a Senior ML Developer Consultant with strong software engineering skills and practical experience taking Machine Learning models to production. This role focuses on building, deploying and optimizing robust ML‑powered features and applications, requiring a hands‑on approach to MLOps, system integration and performance tuning. The ideal candidate will be a high‑contributing individual who can bridge the gap between Data Science prototypes and reliable, scalable production systems.

What You Will Do

ML System Implementation & Development

• End‑to‑End Pipeline Implementation: Implement and maintain end‑to‑end Machine Learning pipelines, focusing on robustness from data validation through to serving.
• Model Deployment: Deploy, integrate and maintain production ML models using the H2O MLOps framework, ensuring high reliability, low latency and efficient performance.
• Feature Integration: Develop efficient data processing pipelines and integrate models with existing data architectures (data warehouses, feature stores).
• Performance Optimization: Optimize model inference and system throughput for specific application requirements.

Software Engineering & MLOps

• Application Development: Build Python‑based APIs and microservices for real‑time and batch model prediction.
• MLOps Practices: Implement and enforce MLOps best practices, including continuous integration/continuous deployment (CI/CD), automated testing and proper model versioning.
• Monitoring: Set up and maintain monitoring for deployed models, tracking performance, data drift and system health.
• Infrastructure Collaboration: Work closely with infrastructure and platform teams to ensure optimal resource allocation and scalability on cloud platforms.

What We Are Looking For

Core Programming & ML Fundamentals

• Proficiency in Python: Expert‑level proficiency in Python and strong command of SQL. Working knowledge of C/C++ or Bash is a plus.
• ML Frameworks: Deep experience with key ML frameworks: TensorFlow, PyTorch, scikit‑learn, H2O3 and Driverless AI.
• Data Libraries: Extensive, hands‑on experience with core data processing libraries: NumPy, Pandas and Matplotlib.
• Application Development: Proven experience building applications and APIs using modern frameworks (e.g., Flask or FastAPI).

MLOps and Infrastructure

• Containerization & Orchestration: Strong practical experience with Docker and foundational knowledge of Kubernetes for deployment.
• Cloud Platforms: Experience deploying and operating ML workloads on at least one major cloud provider (AWS, GCP or Azure).
• Workflow Tools: Experience with ML workflow orchestration tools such as Airflow, Kubeflow or MLflow.
• Software Practices: Strong software development practices, including Git, unit testing, code review and experience with microservices architecture.

Advanced Capabilities (Hands‑On)

• Experience working with large language models (LLMs) or multimodal data (text, images, time‑series) in an applied setting, including experience with H2OGPTe.
• Familiarity with model serving patterns, auto‑scaling and resource management in a production context.
• Experience with performance profiling and basic model optimization techniques.

Experience & Professional Skills

• Education & Experience: Master's degree in Computer Science, Engineering or a related technical field, plus 4+ years of professional experience building and deploying production software/ML systems.
• Problem‑Solving: Strong debugging, troubleshooting and analytical skills for diagnosing and resolving production system issues.
• Collaboration: Proven ability to collaborate effectively with data scientists and software engineers to transition experimental models into reliable production code.
• Delivery Focus: Track record of driving projects to completion and meeting strict performance requirements.
