The Role:

As a Senior Associate, Machine Learning Engineer, you'll work alongside experienced ML engineers and data scientists to design, build, and scale machine learning systems that deliver real business value. Reporting to the Executive Director of ML Engineering, you'll gain hands-on experience developing production-grade pipelines, monitoring frameworks, and scalable ML applications that support mission-critical business functions. This is a high-growth opportunity for someone with early industry experience (or strong academic grounding) in machine learning engineering, eager to deepen their expertise in production systems and MLOps while growing within a dynamic AI team operating at the frontier of applied ML.

Responsibilities:

• Contribute to the design, development, and deployment of ML models and pipelines across business-critical domains such as financial services and insurance.
• Support production efforts, including model packaging, integration, CI/CD deployment, and monitoring for performance, drift, and reliability.
• Collaborate with senior engineers to build internal ML engineering tools and infrastructure that improve training, testing, and observability workflows.
• Partner with Data Scientists to operationalize prototype models, ensuring they are scalable, robust, and cost-efficient in production.
• Work with large-scale datasets to enable feature engineering, transformation, and quality assurance within ML pipelines.
• Implement monitoring dashboards, alerts, and diagnostics for model health and system performance.
• Contribute to documentation, governance, and reproducibility practices, supporting compliance in regulated environments.

Requirements

• 5+ years of experience building and deploying machine learning models in production environments, with exposure to monitoring and diagnostics.
• Solid understanding of machine learning engineering fundamentals (pipelines, deployment, monitoring) and familiarity with data science workflows.
• Experience with MLOps tools such as MLflow, Weights & Biases, or equivalent. Exposure to observability/monitoring systems (Prometheus, Grafana, ELK, Datadog) is a plus.
• Proficiency in Python and familiarity with ML libraries (scikit-learn, XGBoost, TensorFlow, PyTorch).
• Strong experience with data manipulation and pipelines using Pandas, NumPy, and SQL.
• Knowledge of containerized deployments (Docker, Kubernetes) and cloud ML services (AWS SageMaker, GCP Vertex AI, or Azure ML) preferred.
• Excellent problem-solving skills, eagerness to learn, and ability to thrive in a fast-paced, evolving environment.
• Bachelor's or Master's degree in Computer Science, Machine Learning, or a related technical field.
• Strong written and verbal communication skills, with the ability to explain technical details to both technical and business stakeholders.

Preferred experience:

• Hands-on experience with Palantir platforms (Foundry, AIP, Ontology), including deploying and integrating ML solutions in enterprise ecosystems.
• Familiarity with vector databases (FAISS, Pinecone, Milvus, Weaviate) and LLM engineering workflows.
• Exposure to graph databases (Neo4j, TigerGraph) and their application in AI/ML systems.

Benefits

• Work at the forefront of AI/ML innovation in life insurance, annuities, and financial services.  
• Drive AI transformation for some of the most sophisticated financial entities.  
• Competitive compensation, benefits, future equity options, and leadership opportunities.
