Remote Forge AI Engineer: Build Autonomous Agent Platform

Norstella; Montpelier (VT); Remote; USD 180,000 - 240,000; Full time

Job summary

Norstella is building Forge — a greenfield agentic platform that replaces the human-driven SDLC with an autonomous agent chain, end-to-end. You' 0d be working across the full stack: orchestration, multi-agent coordination, MCP server design, RAG pipelines, eval harnesses, and safety primitives that make non-deterministic systems trustworthy in production.

The platform is live and shipping. The hard problems are real: agent memory and state across multi-step runs, inter-agent trust, cost

Qualifications

• 6+ years of software engineering, with at least 2 years building and operating LLM-powered or agentic systems in production.
• Experience with at least one agentic framework and a clear understanding of trade-offs.
• Hands-on experience authoring MCP servers or tool-use APIs with contracts and versioning.
• Experience with agent memory architectures — context management and long-term memory stores.
• Strong fundamentals in Python and/or TypeScript; able to own production agent code.
• Proficiency in prompt engineering, tool calling, and multi-step orchestration.

Responsibilities

• Design and build agents across the Forge chain — orchestration, tool-use surfaces, MCP server integrations, prompt and RAG pipelines.
• Own multi-agent coordination architecture: inter-agent trust boundaries, message schema contracts, partial failure handling and recovery.
• Build and evolve the MCP server layer — tool schema design, capability contracts, versioning for safe extension.
• Design agent memory and state management: context window strategy, long-term memory integration, persistence across complex workflows.
• Own agent quality end-to-end: eval harnesses, behavioral benchmarks, continuous evaluation pipelines, and release gates.
• Instrument agent-specific observability — token tracing, tool-call chain logging, cost attribution per run.
• Build safe-by-design primitives: least-privilege tool-use, PII/PHI handling, structured output validation, security partnership.
