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.

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.
