AI Engineer

Alight is building an AI engineering platform to support AI delivery across the organization. As an AI Engineer, you will help production teams ship agentic experiences with strong retrieval, evaluation, and operational controls. This is a hands-on role focused on building the patterns, infrastructure, and tooling that keep AI systems reliable and measurable.

What you’ll build

• Agent patterns, retrieval, and guardrails for assistant experiences that answer participant questions and can carry out transactions on their behalf
• A dedicated MCP server that provides a skills registry for AI coding agents directly inside the IDE
• Reusable agent architectures in LangGraph, including multi-agent orchestration, memory, and tool-use safety with guardrails
• An agent evaluation platform using frameworks such as DeepEval and Ragas, with quality gates that prevent poor deployments in CI/CD
• Document ingestion and retrieval pipelines covering chunking, embedding, vector search, reranking, and citations
• CI/CD and deployment automation for AI agents on AWS, including ECS, Fargate, and Agent Core
• AI-enabled devcontainers with built-in tooling, validation, and testing
• Production observability with OpenTelemetry, including dashboards plus LLM cost and token tracking
• Governance controls implemented as automated pipeline checks with evidence collected automatically
• Scalability features such as semantic caching, rate limiting, and graceful degradation under load
• Reference implementations, along with SDK and CLI tooling, and documentation that other engineers rely on

Core requirements

• Python (3.10+) as the primary language for the team
• AWS working knowledge of key services such as IAM, ECS/Fargate, and networking, plus comfort in cloud-native environments
• Software engineering discipline, including version control (Git/GitHub), code review, testing, documentation, and clean code
• Security awareness, with attention to secrets, permissions, and data protection for systems handling sensitive information

Where your expertise fits

• AI agent development: LangGraph or similar, multi-agent orchestration, memory, tool use, guardrails, prompt and workflow design
• Data and retrieval engineering: chunking, embeddings and vector search, RAG, hybrid search, reranking, retrieval evaluation
• Quality and evaluation: DeepEval and Ragas, CI/CD quality gates, groundedness and safety metrics, test automation
• Platform and infrastructure: CI/CD, Terraform, AWS container orchestration (ECS, Fargate), secrets and IAM, progressive deployment
• Observability and operations: OpenTelemetry tracing, dashboards and alerting, LLM cost and token tracking, feedback loops
• Developer experience: MCP servers, devcontainers, CLI and SDK tooling, prompt libraries, documentation, and reference implementations

Benefits and support

• Health, dental, and vision coverage starting Day One
• Wellbeing programs
• Retirement plans with contribution matching
• Generous time off
• Parental leave
• Continuing education
• Career growth opportunities
