As the Staff Machine Learning Engineer (VP) on the ML Engineering team, you will be responsible for designing, deploying, and scaling advanced ML systems that power core business functions across the enterprise. Reporting to the Executive Director of ML Engineering, you will play a critical role in building production-grade ML infrastructure, reusable frameworks, and scalable model pipelines that deliver measurable business outcomes—ranging from cost optimization to top-line growth. You will act as a technical thought leader and strategic partner, shaping the organization\'s machine learning engineering practices and fostering a culture of operational excellence, reliability, and responsible AI adoption.

• Architect and deploy ML systems and platforms that solve high-impact business problems across regulated enterprise environments.
• Lead the development of production-ready pipelines, including feature stores, model registries, and scalable inference services.
• Champion MLOps best practices (CI/CD for ML, model versioning, monitoring, observability) to ensure models are reliable, reproducible, and cost-efficient.
• Partner with Data Scientists to operationalize experimental models, enabling scalability and generalizability across diverse business domains.
• Integrate emerging ML engineering techniques (e.g., LLM deployment, fine-tuning pipelines, vector databases, RAG systems) into enterprise-ready solutions.
• Own the design of foundational ML platforms and frameworks that serve as building blocks for downstream AI applications.
• Embed controls, governance, and auditability into ML workflows, ensuring compliance with regulatory standards and responsible AI principles.
• Collaborate with Engineering, Product, and Security teams to embed ML-driven decision-making into enterprise platforms and workflows.
• Define and track engineering and model performance metrics (latency, scalability, cost, accuracy) to optimize systems in production.
• Mentor and coach ML engineers, fostering technical excellence, collaboration, and innovation within the AI Science team.

• 8+ years of experience building and deploying machine learning systems in production environments at enterprise or platform scale.
• Proven track record of leading ML engineering projects from architecture to deployment, including ownership of production-grade systems.
• Deep expertise in ML frameworks and engineering stacks (TensorFlow, PyTorch, JAX, Ray, MLflow, Kubeflow).
• Proficiency in Python and at least one backend language (e.g., Java, Scala, Go, C++).
• Strong understanding of cloud ML infrastructure (AWS SageMaker, GCP Vertex AI, Azure ML) and containerized deployments (Kubernetes, Docker).
• Hands-on experience with data and model pipelines (feature stores, registries, distributed training, inference scaling).
• Knowledge of observability and monitoring stacks (Prometheus, Grafana, ELK, Datadog) for ML system performance.
• Experience collaborating with cross-functional teams in regulated industries (finance, insurance, health) with compliance and governance needs.
• Exceptional communication and leadership skills, with the ability to translate complex engineering challenges into clear business outcomes.
• Master\'s or PhD in Computer Science, Machine Learning, or related technical discipline.

• Hands-on experience with Palantir platforms (Foundry, AIP, Ontology), including developing, deploying, and integrating ML solutions in enterprise ecosystems.
• Exposure to LLM and GenAI engineering (fine-tuning, vector search, distributed inference).
• Experience optimizing GPU clusters, distributed training, or HPC environments.
• Familiarity with graph databases (e.g., Neo4j, TigerGraph) and their application in AI/ML systems.

• 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.
