About the Role

We’re looking for a Senior Solution Architect to lead the design of an end-to-end Agentic AI pipeline for an enterprise cybersecurity proof of concept. You’ll be the technical authority for a multi-agent workflow that detects, plans and remediates cryptographic vulnerabilities, using large language models on AWS. Your architecture will take a real-world security problem, such as weak algorithms, hardcoded keys or insecure TLS, from scan finding to human-approved fix.

What You’ll Do

• Architect a multi-agent LangGraph workflow hosted on AWS ECS Fargate
• Design the LLM integration layer on Amazon Bedrock (Claude and other foundation models) for automated vulnerability remediation
• Architect a Retrieval-Augmented Generation (RAG) system on Amazon OpenSearch that maps security scan findings to enterprise rule dictionaries
• Design a state-management layer in DynamoDB that tracks remediation checkpoints and supports pause-and-resume
• Design a secure Reviewer Dashboard with API Gateway, AWS Lambda and Amazon Cognito, providing human-in-the-loop approval gates
• Define security, networking and guardrail standards across the pipeline, including private networking, least-privilege access, prompt-injection defenses and audit logging
• Partner with security, engineering and DevSecOps stakeholders to turn POC requirements into a production-ready blueprint

What You Bring

• Senior-level expertise in cloud and software architecture
• Deep, demonstrable expertise in AWS networking (VPC, PrivateLink and VPC endpoints), compute (ECS/Fargate) and serverless data stores (DynamoDB, OpenSearch)
• Hands-on architectural experience with Generative AI orchestration frameworks, specifically LangGraph and LangChain
• Experience designing RAG systems: vector indexing, hybrid search and retrieval evaluation
• Strong foundation in DevSecOps practices and automated remediation pipelines (CI/CD, SAST, policy-as-code)
• Ability to explain architecture decisions and trade-offs clearly to both technical and executive audiences
• Able to work onsite in Irving, TX 2–3 days per week

Nice to Have

• AWS Certified Solutions Architect – Professional (highly preferred)
• Experience with Amazon Bedrock Guardrails, Bedrock Agents or AgentCore
• Background in applied cryptography or post-quantum cryptography migration (NIST ML-KEM / ML-DSA)
• Infrastructure as Code (Terraform or AWS CDK)
