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 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 (e.g., 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.
