Agentic AI Engineer — Hybrid Boston Role

IANS Research; Boston (MA); On-site; USD 135,000 - 170,000; Full time

Job summary

IANS Research is seeking an Agentic Engineer in Boston, MA to build and ship agent capabilities within our AI platform. This hands-on role focuses on production-quality agent tooling, retrieval components, and evaluation infrastructure that power our internal and client-facing systems.

You will work with Go, Python, and TypeScript across services, AI workflows, and web apps, joining a team that values observability, security, and scalable design.

Qualifications

• 3–5 years of software engineering experience, including hands-on work building LLM powered features or agentic systems that reached production users.
• Proficiency in Go, or strong proficiency in a comparable systems language (Rust, TypeScript, Java, C#) with the ability to become productive in Go quickly; working knowledge of Python for AI/ML workflows.
• Experience building web applications with React and TypeScript.
• Experience building and shipping LLM-powered applications — whether with an agent framework such as LangChain, LangGraph, LlamaIndex, or AutoGen, or directly against model APIs.
• Working understanding of RAG, embeddings, vector databases, and prompt/context.
• Familiarity with cloud infrastructure, ideally AWS (ECS, Lambda, Bedrock, or comparable services).
• Strong testing and debugging discipline, and the habit of instrumenting what you ship.
• Clear written and verbal communication and a demonstrated appetite for feedback and growth.

Responsibilities

• Build, test, and ship production-quality agent capabilities — tools, retrieval components, memory features, orchestration steps, and evaluation coverage — within the platform's established architecture.
• Implement agent and tool-use patterns with frameworks such as LangChain, LangGraph, LlamaIndex, AutoGen, or comparable systems.
• Integrate retrieval-augmented generation (RAG), structured tool use, MCP-style tool protocols, and APIs into robust, enterprise-grade platform components.
• Contribute to the developer-facing primitives that allow external clients to safely extend the IANS agent platform with their own data and workflows.
• Extend benchmarking, regression testing, and observability suites that measure agent quality, latency, cost, reliability, and safety.
• Write and maintain evaluations for agentic behaviors — tool-use correctness, hallucination rates, multi-turn coherence, and task completion.
• Investigate eval regressions and production incidents in agent behavior, and land the fixes.
• Participate in design reviews and code reviews, absorbing and applying feedback from senior and principal engineers.
• Take progressively larger ownership as you build a track record, from features to subsystems.
• Stay current on the agentic AI landscape and share learnings with the team.
