Contract Biomedical Machine Learning Jobs in Simi Valley, CA

Job Title: AI/ML Architect with Databricks, Azure

Location: Los Angeles CA or New York NY (Hybrid)

Hire type: Contract

Need 15+ years of experience resumes. 

Role Overview

We are seeking an experienced AI/ML Architect with deep hands-on expertise in Databricks on AWS to lead the design and implementation of scalable, high‑performance data and machine learning platforms. The ideal candidate combines architectural thinking with strong engineering execution, demonstrating the ability to build modern Lakehouse systems, optimize large‑scale pipelines, and drive analytical and ML capabilities across the organization.

This role requires working with large, multi-terabyte datasets, advanced analytics, and end‑to‑end ML lifecycle management using Databricks, Python, PySpark, and AWS-native services.

Must Demonstrate (Critical Competencies)

• Designing Databricks‑based lake house architectures on Azure (Delta Lake + S3 + Unity Catalog).
• Clear separation of compute vs. serving layers in distributed architectures.
• Low-latency API strategy where Spark is insufficient (e.g., leveraging optimized services or caching).
• Caching strategies to accelerate reads and reduce compute cost.
• Data partitioning, file size tuning, and optimization strategies for large-scale pipelines.
• Experience handling multi-terabyte structured time‑series workloads.
• Ability to distill architectural significance from ambiguous business requirements.
• Strong curiosity, questioning, and requirement‑probing mindset.
• Player‑coach approach: hands-on technical depth + ability to guide design.

Key Responsibilities

AI/ML & Advanced Analytics

• Develop, train, and optimize ML models using Python, PySpark, MLflow, and Databricks Machine Learning.
• Conduct exploratory data analysis (EDA) to identify patterns, trends, and insights in large datasets.
• Deploy ML models into production using MLflow, Databricks Workflows, or other MLOps pipelines.
• Build analytics solutions such as forecasting, anomaly detection, segmentation, or recommendation systems.
• Design ML architectures aligned with Databricks Lakehouse on Azure.

Data Engineering & Lakehouse Architecture

• Architect and build scalable ETL/ELT pipelines using PySpark, SQL, and Databricks Workflows.
• Implement Delta Lake best practices, including OPTIMIZE, ZORDER, partitioning, and schema evolution.
• Design lakehouse layers (Bronze/Silver/Gold) with strong separation of compute and serving layers.
• Optimize cluster performance and jobs using Spark tuning, caching, and shuffle minimization.
• Work with multi-terabyte, time-series, high‑velocity data in a distributed environment.
• Ensure robust data availability for downstream ML and analytics workloads.

AWS Cloud Integration

• Architect end-to-end data and ML solutions using Azure services, including:
• S3 for storage
• IAM for identity & access
• Glue Catalog for metadata management
• Networking for secure, high‑throughput data movement
• Integrate Databricks with AWS-native compute, API layers, and low-latency endpoints.

Business Collaboration & Leadership

• Translate business problems into scalable analytical or ML architectures.
• Communicate complex statistical and architectural concepts to non‑technical stakeholders.
• Collaborate with product, engineering, and business leaders to drive data-informed initiatives.
• Provide design leadership while remaining hands-on in execution.

Skills & Qualifications

Required

• Bachelor’s or Master’s in Computer Science, Data Science, Engineering, Statistics, or related field.
• Deep expertise in Databricks on AWS, including:
• PySpark / Spark SQL
• Databricks Notebooks
• Delta Lake
• Unity Catalog
• MLflow
• Databricks Jobs & Workflows
• Strong programming ability in Python (pandas, numpy, scikit-learn).
• Demonstrated experience with large-scale, multi-terabyte data processing.
• Strong understanding of ML algorithms, distributed systems, and data optimization.

Preferred

• Experience with MLOps and production deployment pipelines.
• Strong grasp of AWS-native data and compute services.
• Understanding of CI/CD using GitHub Actions, GitLab CI, or similar.
• Familiarity with deep learning frameworks (TensorFlow, PyTorch).

Key Competencies

• Strong analytical and problem-solving skills.
• Ability to work in fast-paced, highly collaborative environments.
• Excellent communication and presentation abilities.
• Self-driven with exceptional attention to architectural detail.
