About The Position

Fisher Investments is seeking a Senior MLOps Engineer to build infrastructure, pipelines, and operational practices that move machine learning and generative AI solutions from experimentation into reliable, secure, scalable production services. The role builds, deploys, and operates ML and generative AI solutions in enterprise environments, working closely with AI leads, ML engineers, and platform teams to create production-ready services and operational practices. The position reports to the AI Team Leader, Technology Innovation.

The engineer will develop end-to-end data and ML pipelines on Azure and Databricks; operationalize retrieval-augmented generation and context-engineering workflows; build production APIs and microservices; deploy and scale model-serving endpoints and containerized inference services; and manage cloud resources through infrastructure as code. The role also establishes testing, release quality gates, versioning, experiment tracking, monitoring, security controls, and operational safeguards.

Requirements

• 10+ years of experience building data-driven software solutions, including 5+ years of hands-on machine learning engineering experience.
• 8+ years of Python development experience, including building and maintaining production services, APIs, or data pipelines.
• Demonstrated experience deploying and operating machine learning or generative AI solutions in production.
• Experience with Databricks, including Delta Lake, Auto Loader, Workflows, Feature Engineering, and deployment automation using Databricks Asset Bundles.
• Hands-on experience building CI/CD pipelines and implementing automated testing and deployment workflows for data and ML systems.
• Hands-on experience with cloud-native AI infrastructure and related technologies, including Azure Foundry, Azure Kubernetes Service, Docker, and GPU-backed workloads.
• Hands-on experience integrating and operating graph databases to support knowledge graphs, relationship-based retrieval, or generative AI applications.
• Bachelor's degree in computer science, Artificial Intelligence, or a related field, or equivalent professional experience.

Nice To Haves

• Experience deploying models for low-latency, high-throughput inference using frameworks such as vLLM and other GPU-based model-serving tools.
• Experience with distributed training, GPU optimization, and GPU computing technologies such as CUDA and RAPIDS.

Responsibilities

• Design, build, and operate end-to-end data and ML pipelines on Azure and Databricks, covering ingestion, validation, feature engineering, model training, fine-tuning, evaluation, and deployment.
• Build and maintain CI/CD workflows for application code, model artifacts, prompt templates, retrieval and context configurations, evaluation datasets, and infrastructure.
• Operationalize RAG and context-engineering workflows, including document ingestion, chunking, embedding generation, indexing, retrieval, context selection and assembly, and evaluation of retrieval and response quality.
• Collaborate with ML engineers, data engineers, and the AI Lead to turn experimental training, fine-tuning, evaluation, and inference workflows into reproducible, production-ready systems.
• Develop and maintain production-grade APIs and microservices using Python and FastAPI to expose model inference and integrate AI capabilities into enterprise applications.
• Deploy, operate, and scale model-serving endpoints and containerized inference services using Azure-managed services, Docker, and Kubernetes according to workload requirements.
• Provision and manage cloud and platform resources through infrastructure as code, ensuring consistent, repeatable, and auditable environment configurations.
• Implement automated testing and release quality gates for application code, data quality, model performance, retrieval quality, AI safety, and deployment readiness.
• Establish model and artifact versioning, experiment tracking, and deployment traceability to support reproducibility and troubleshooting.
• Monitor and improve model quality, data and retrieval pipeline reliability, inference latency, throughput, service availability, and infrastructure cost efficiency.
• Partner with infrastructure, security, and governance teams to implement appropriate access controls, auditability, and operational safeguards.

Benefits

• 100% paid medical, dental, and vision premiums for the employee and qualifying dependents.
• A 50% 401(k) match, up to the IRS maximum.
• 20 days of PTO and 10 paid holidays.
• Family Support programs, including 8-week Paid Primary Caregiver Leave, $10,000 fertility, family-forming, and hormonal health assistance, and backup child, adult, and elder care.
• Learning and development framework customized for every employee.
