Role Summary

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
• 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

• Architect and evolve service-oriented and event-driven systems supporting AI workloads
• Design REST/Graph
  
  QL APIs with clear versioning, authentication, and backward compatibility strategies
• Implement asynchronous processing pipelines using queues, event buses, and workflow orchestration
• Ensure reliability through idempotent consumers, retry strategies, circuit breakers, and dead-letter…
