Job description

We are hiring a Senior Software Engineer (AI/Agentic, Full Stack) in Remote (US) to support our client’s growing enterprise software modernization team. This Senior Software Engineer job in the United States is ideal for candidates with experience in autonomous agents, LLM workflows, LangChain / LangGraph, Python, .NET, TypeScript, SQL, RAG, vector databases, ERP modernization, prompt engineering, and CI/CD.

Join a specialized modernization strike team building AI native, agentic workflows that transform how enterprise systems are built, tested, and operated. You’ll design and ship production grade features by combining LLM tool-calling, evals/guardrails, and observability to modernize legacy ERP modules into reliable, testable services. If you’ve already automated parts of your job and think in capabilities, agents, and workflows, this role is built for you.

This role requires hands-on experience building and deploying AI/LLM systems to production environments. Academic or tutorial experience alone is not sufficient.

PLEASE NOTE: We do not accept applications from third-party recruiters or staffing agencies. We are currently only able to hire candidates who reside in and are authorized to work in the United States due to legal, tax, and operational requirements.
