Job Description

The Principal Machine Learning Operations Engineer (Principal MLOps Engineer) is an action-oriented position that designs and builds automated processes. These processes focus on machine learning (ML) service and infrastructure stability, which enables our digital Educational Technology (Ed Tech) transformation product to use advanced NLP, knowledge engineering, and ML to accelerate innovation in scientific operations. The ideal candidate will have cloud infrastructure, IAC, and monitoring/instrumentation skills. A proven track record of collaboration, iteratively implementing data-intensive solutions, and strong project leadership are also required to be successful in this role. The Principal MLOps Engineer will educate stakeholders, mentor team members and, with a strong vision for how the ML/SE discipline can proactively create positive impacts, have a significant stake in defining the future of the Ed Tech function for WGU.

Job Responsibilities

Platform Ownership & Development

• Architect, build, and maintain ML infrastructure leveraging Databricks and AWS.

• Lead the development of reusable MLOps tooling, SDKs, CI/CD templates, and pipelines.

• Implement and extend Databricks Asset Bundles, Databricks APIs, and Agent Frameworks for model and GenAI workloads.

CI/CD & Automation

• Design and implement automated CI/CD pipelines using tools like GitHub Actions, Infrastructure-as-Code (Terraform, AWS CDK), and templating frameworks (Copier, Cookiecutter).

• Automate testing, deployment, and rollback workflows to streamline ML lifecycle from experimentation to production.

Model Lifecycle Management

• Manage the ML lifecycle using MLflow for both classic ML (experiments, registry) and GenAI use cases (traces, evaluations).

• Collaborate with data scientists to deploy, monitor, and iterate on ML models in real-time and batch inference environments.

• Develop scalable and low-latency online inference systems, exposed via APIs or service endpoints.

Monitoring, Observability & Performance

• Implement monitoring solutions for drift detection, data quality, throughput, latency, and model performance using tools like Evidently and custom dashboards.

• Proactively manage model and system reliability, scalability, and resiliency in production environments.

GenAI & Agentic Workflows

• Design and deploy agentic workflows using frameworks like LangChain, and integrate with Databricks Agent Frameworks.

• Collaborate with ML/GenAI teams to evaluate and productionize LLM-based applications and tools.

• 7+ years of software engineering or DevOps experience, with at least 4 years focused on MLOps or ML infrastructure.

• Deep experience with Python, SQL, and Databricks platform development.

• Strong proficiency in deploying and managing ML systems on AWS, including EC2, S3, EKS, SageMaker, or Lambda.

• Hands-on experience with MLflow, GitHub Actions, Databricks SDKs, and infrastructure as code tools (Terraform, CDK, etc.).

• Experience building and maintaining CI/CD pipelines, unit and integration tests, and using YAML for workflow orchestration.

• Expertise in building low-latency real-time inference systems, REST/gRPC APIs for model serving, and related architecture patterns.

• Experience working with agentic frameworks (LangChain, etc.) for GenAI applications.

• Demonstrated ability to monitor production systems for performance, reliability, and model quality.

• Proven track record of writing production-grade code and reusable abstractions for ML/AI systems.

• Strong communication and cross-functional collaboration skills.

• PhD in Computer Science, Software Engineering, Data Science, Machine Learning, Math, Physics, or a related field

• Experience working with knowledge graphs stores (Stardog, TigerGraph, Ontotext GraphDB, Neo4j) and surrounding semantic technology (OWL, RDF, SWRL, SPARQL, JSON-LD)

• Proficient in modern big data architectural approaches (Kappa/Lambda architectures, Data Lake Zones, etc.)

• Mastery of operating and designing stream-based data systems (Kafka, AWS Kinesis, GCP PusSub, etc.) particularly under varying load

• Deep understanding of theoretical and practical tradeoffs of various NoSQL stores (Cassandra, Elasticsearch, Dynamo DB, etc.) with respect to different read/write patterns and availability/consistency requirements

• Cloud infrastructure, IAC, and monitoring/instrumentation skills
