Full-time
On-site
Dallas, Texas, United States
This hybrid role in Dallas, TX focuses on designing, building, and deploying autonomous and semi-autonomous AI agents on AWS. You will work with goal-driven, tool-using, multi-step systems that combine AWS AI/ML services with LLMs, while integrating enterprise systems and emphasizing production-grade safety and reliability.
Responsibilities
Design and develop agentic AI systems using
Amazon Bedrock
and other foundation models, including
Claude
and
Titan . Build autonomous and semi-autonomous AI agents that perform multi-step reasoning, planning, tool usage, action execution, and human-in-the-loop collaboration. Integrate with
Amazon SageMaker
for custom model training, fine-tuning, evaluation, and experimentation. Implement
Retrieval Augmented Generation (RAG)
solutions using
Amazon OpenSearch ,
Amazon Aurora ,
DynamoDB , and vector databases such as
FAISS
or
Pinecone . Optimize inference cost, latency, scalability, and reliability across AI workloads. Implement guardrails, validation layers, and human-in-the-loop controls to support safe, reliable, and predictable AI behavior. Address hallucination mitigation, prompt injection risks, bias concerns, and model misuse scenarios. Ensure compliance with enterprise AI governance, security, and regulatory standards. Implement comprehensive logging, monitoring, observability, and audit trails for AI systems. Support production deployments, incident resolution, and root cause analysis for AI services. Continuously improve agent performance, reliability, robustness, and usability through iteration, monitoring, and feedback. Collaborate with architecture, DevOps, data engineering, security, and business teams to deliver end-to-end AI solutions. Requirements
Bachelor’s degree in
computer science, Engineering, Technology, or a related field , with
8–12 years of overall IT experience
and at least
3+ years of hands‑on experience
building agentic AI solutions using
AWS cloud‑native services . Strong expertise in core AWS services:
AWS Lambda ,
Step Functions ,
EventBridge ,
S3 ,
DynamoDB
or
Aurora ,
OpenSearch ,
Amazon Bedrock , and
Amazon SageMaker . Advanced proficiency in
Python
for building scalable AI systems and automation workflows. Proven experience leading the technical design and implementation of complex AI agent architectures and components. Hands‑on experience designing
RAG
solutions and applying model fine‑tuning techniques. Demonstrated ability to manage performance, scalability, reliability, and cost optimization of AI workloads in production environments. Proven experience conducting code reviews, leading knowledge‑sharing sessions, and making critical decisions on technologies, architectures, and frameworks. Healthcare domain experience is desirable, along with knowledge of AI safety, governance, compliance, and responsible AI practices. AWS certifications such as
Solutions Architect
or
Machine Learning Specialty
are preferred; experience with
LangChain
and
LangGraph
is a plus. Excellent communication skills with the ability to collaborate effectively with technical and non-technical stakeholders. Required Skills & Technologies
AWS, Amazon Bedrock, Amazon SageMaker, Amazon OpenSearch, Amazon Aurora, DynamoDB AWS Lambda, Step Functions, EventBridge, S3 Python Claude, Titan FAISS, Pinecone LangChain, LangGraph Experience
