About the role

Stealth Talent Solutions is hiring a Lead AI Platform Engineer for a global consulting firm. The work supports a major sports and entertainment organization.

You’ll be the hands‑on lead engineer on an enterprise generative AI platform on AWS. It serves the organization’s entire workforce, with governed access to frontier LLMs, per-user and per-team cost tracking, and a RAG layer over company knowledge.

This is an immediate need. We want someone who can step into an existing build, learn it fast and keep shipping. You’ll write code every day and work directly with the client.

What you’ll do

• Write and review code across the Python/FastAPI backend and the React/TypeScript front end
• Own the multi-account AWS setup in Terraform: VPC, IAM, KMS, Secrets Manager, EventBridge, CloudFront and WAF
• Ship releases through GitHub Actions with OIDC federation, from dev through QA to production
• Build on AWS Bedrock (Anthropic Claude), including model routing and usage and cost tracking by user and team
• Build and maintain the RAG layer on MongoDB Atlas Vector Search, with streaming responses through API Gateway WebSocket and Lambda
• Manage sign-in and access with Okta
• Support client testers, write release notes and answer the client’s technical and security questions

What you bring

• 8+ years of production software engineering, and you still code every day
• Strong communication skills. You’re comfortable in front of clients and can explain technical decisions clearly.
• Python/FastAPI and React/TypeScript
• AWS serverless: Lambda, API Gateway (including WebSocket), S3 and CloudFront
• Hands‑on experience building with LLMs, ideally AWS Bedrock
• MongoDB, with Atlas and Vector Search a plus
• Terraform on AWS
• GitHub Actions CI/CD
• Okta or OIDC

Nice to have

• Multi-account AWS and WAF
• LLM cost tracking and model routing
• MCP servers and agent frameworks
• Pen-test remediation

Details

• Contract-to-hire. 3 months with the option to convert, or stay on contract for up to 12 months.
• Start ASAP
• Remote, with travel to Washington, DC. Travel expenses are reimbursed.
• Must be authorized to work in the US. No sponsorship available.
