Join Suffolk's AI Studio in Boston as an AI Systems Engineer, a hybrid role responsible for architecting and building both:

The distributed systems backbone that powers enterprise-scale AI, and

1. The agentic and LLM-driven capabilities transforming construction workflows

This role sits at the intersection of platform engineering and applied AI. You will design scalable APIs, event-driven services, and reliable infrastructure - while also implementing multi-model AI agents, retrieval pipelines, and AI orchestration frameworks that operate in real-world production environments.

You will help define how AI is built, deployed, observed, and scaled across Suffolk's national operations.

AI & Agentic Systems Product Engineering & Deployment

• Design and implement production-grade RAG architectures
• Build and deploy multi-model AI agents leveraging AWS Bedrock and LLM providers (Claude, GPT, Llama, Titan, etc.)
• Implement dynamic model routing strategies based on task complexity, cost, and latency
• Develop multi-agent orchestration frameworks enabling collaborative workflows (planner, retriever, executor, summarizer)
• Design safe tool invocation patterns and guardrails for enterprise AI agents
• Optimize inference pipelines for cost, performance, and reliability
• Implement evaluation frameworks to measure model performance, hallucination rates, and response quality
• Design fallback and degradation strategies for model outages or latency spikes

Distributed Systems & Platform Architecture

What Makes This Role Unique

This role requires equal fluency in:

• Designing distributed systems that scale
• Engineering intelligent agentic systems that reason

We are looking for engineers who understand that production AI is not just about model quality and prompt engineering - it is also about the systems that deliver, monitor, and evolve those models and agents safely at scale.
