Remote Senior Forge AI Engineer - Agent Platform

Norstella; Honolulu (HI); Remote; USD 150,000 - 230,000; Full time

Job summary

Norstella is seeking a Senior Forge AI Engineer to lead the development of Forge, a greenfield agentic platform. You will work across the full stack—from orchestration and multi-agent coordination to MCP server design and RAG pipelines—building a trustworthy production system.

The role emphasizes agent memory, state management, safety primitives, and observability. Remote US-based candidates with strong Python/TypeScript skills are encouraged to apply.

Qualifications

• 6+ years software engineering experience.
• 2+ years building and operating LLM-powered or agentic systems in production.
• Experience with an agentic framework (LangGraph, CrewAI, Autogen, Semantic Kernel, MCP, or comparable).
• Strong fundamentals in Python and/or TypeScript; able to own production agent code.

Responsibilities

• Design and build agents across the Forge chain — orchestration, tool-use surfaces, MCP server integrations, prompt and RAG pipelines — and set the agentic design patterns the team ships against.
• Own multi-agent coordination architecture: inter-agent trust boundaries, message schema contracts, partial failure handling, and recovery across the agent graph.
• Build and evolve the MCP server layer — tool schema design, capability contracts, versioning — so Forge's tool-use surface is well-defined and safe to extend.
• Design agent memory and state management: context window strategy, long-term memory integration, state persistence across complex multi-step workflows.
• Own agent quality end-to-end: eval harnesses, behavioral benchmarks, continuous evaluation pipelines, and the acceptance criteria that gate every agent release.
• Instrument agent-specific observability — token tracing, tool-call chain logging, cost attribution per run — so the platform is debuggable and defensible.
• Build safe-by-design primitives: least-privilege tool-use, PII/PHI handling, structured output validation, red-team partnership with Security.
