Gen AI Engineer

GenAI Platform Engineer

Boston, MA

Full-time role

Experience: 10+yrs

About the Role

We''''re looking for a Senior GenAI Platform Engineer to build and operate our enterprise AI agent platform — hands-on, in the code, every day. This is an individual contributor role with no direct reports. You''''ll design and build durable asynchronous orchestration, RAG pipelines, and secure multi-agent workflows on AWS, working alongside a small team of peer engineers. You''''ll participate in architecture discussions and code reviews as a strong technical contributor, not as a manager.

Education & Experience

• Bachelor’s degree in computer science, Information Systems, Engineering, or equivalent practical experience.
• 5–8 years of professional software engineering experience.
• 2+ years of hands-on experience building GenAI/Agentic AI applications in production.

What You''''ll Do

• Build AI agents and multi-agent workflows using Amazon Bedrock, Bedrock Agents, AgentCore, LangChain, and LangGraph.
• Design and implement RAG pipelines, prompt engineering strategies, and AI guardrails.
• Build backend services in FastAPI for agent submission, execution, lifecycle state machines, and status tracking.
• Implement queue-based dispatch and durable state stores, ensuring idempotency, retries, and failure recovery.
• Write Infrastructure as Code (Terraform) to provision and manage agent infrastructure on AWS.
• Integrate agents with vector databases, enterprise messaging systems, and internal workflow tools.
• Instrument services for observability — structured logging, tracing, metrics.
• Participate in code reviews and architecture discussions as a peer contributor.
• Write clear technical documentation (design docs, runbooks) for systems you build.

Required Qualifications

• Expert-level Python, with strong experience building REST APIs (FastAPI preferred).
• Hands-on experience with LLMs, Amazon Bedrock (Agents & AgentCore), LangChain, LangGraph, RAG, and vector databases.
• Strong experience with core AWS services: Lambda, ECS/EKS, API Gateway, S3, RDS/PostgreSQL.
• Working proficiency in Terraform and Docker.
• Experience with CI/CD pipelines (GitHub Actions, GitLab CI, or Jenkins).
• Solid understanding of asynchronous programming and event-driven architectures (Kafka or SQS).
• Experience with modern authentication patterns (OAuth2, OIDC, JWT) and AWS IAM.
