Senior MLOps Engineer

We are looking for a Senior MLOps Engineer to own the agentic versioning model, promotion workflow, and rollback patterns across the agent estate, contributing to an Enterprise Agent Development Platform — a production-grade, cloud-native ecosystem that enables engineering teams to define, orchestrate, deploy, and observe AI agents at scale. The platform standardizes agent development across the organization using LangGraph and Strands Agents on AWS AgentCore Runtime, spanning agent framework design, runtime architecture, marketplace integration, CI/CD automation, and enterprise-grade observability, reducing agent development from months to days while enforcing consistent security, quality, and governance standards.
Responsibilities
Define and maintain the agentic versioning model, treating agent container image, prompt configuration, tool bindings, and policy associations as an immutable unit
Manage AWS AgentCore Runtime versioning, including automatic version creation on image push and endpoint management for DEFAULT and named endpoints
Design and enforce the agent promotion workflow from dev to qa to prod, embedding evaluation gates that guarantee quality before production release
Establish agent rollback patterns that restore previous agent versions while validating that the prior version remains functional
Configure AWS ECR for agent images, covering ARM64 tagging, lifecycle policies, and image signing to preserve agent immutability
Integrate with the Agent Registry to auto-register agent versions along with metadata such as evaluation results and promotion status
Collaborate with engineering teams to standardize versioning and lifecycle practices across the agent estate
Requirements
5+ years of experience in MLOps or DevOps engineering with AI/ML systems
Hands-on experience with deployment, promotion, or rollback workflows specifically for AI agents, such as agent evaluation gates, agent version comparison, or agent endpoint management
Experience in versioning and lifecycle management for LLM agents or ML models
Experience in immutable artifact versioning at enterprise scale using ECR and model registries
Experience in CI/CD pipeline design with quality gates for AI systems
English proficiency at B2 level or higher
Nice to have
Hands-on experience with AWS AgentCore Runtime versioning
Familiarity with agent evaluation frameworks such as Langfuse, LangSmith, PromptLayer
Experience with multi-environment agent promotion patterns
Skills in agent version comparison and regression detection
