Job Description – Senior Forge AI Engineer

About Norstella

Norstella is a premier and critical global life sciences data and AI solutions platform dedicated to improving patient access to life-saving therapies. Norstella supports pharmaceutical and biotech companies across the full drug development lifecycle - from pipeline to patient. Our mission is simple: to help our clients bring therapies to market faster and more efficiently, ultimately impacting patient lives.

Norstella unites five market-leading brands (Citeline, Evaluate, MMIT, Panalgo, and The Dedham Group) that all have a shared vision of improving patient access to life-saving therapy. Norstella delivers must-have answers and insights for critical strategic, clinical, and commercial decision-making. We help our clients:

Accelerate the drug development cycle

Make data driven commercial and financial decisions

Match and recruit patients for clinical trials

Assess competition and bring the right drugs to market

Identify and address barriers to patient access

Leverage the latest AI to turn data into insights for faster and better decision making

Norstella serves almost every pharmaceutical and biotech company in the world, along with regulators like the FDA, and payers. By providing critical proprietary data supporting AI-driven workflows, Norstella helps clients make decisions faster and with greater confidence. Norstella’s investments in AI are transforming how data is consumed and decisions are made, disrupting inefficient legacy workflows and helping the industry become more efficient, innovative, and responsive to patient needs.

About The Position:

Most AI engineering roles ask you to bolt an LLM onto an existing product. This one doesn't. We're building Forge - a greenfield agentic platform that replaces the human-driven SDLC with an autonomous agent chain, end-to-end. You'd be working across the full stack: orchestration, multi-agent coordination, MCP server design, RAG pipelines, eval harnesses, and the safety primitives that make non-deterministic systems trustworthy in production. Not one layer. All of it.

The platform is live and shipping. The hard problems are real: agent memory and state across multi-step runs, inter-agent trust and failure recovery, cost attribution at scale, compliance in a regulated industry. If you want to work at the frontier of agentic systems - not on a demo, on something that actually runs - this is that role.

Key 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.

Required Qualifications

6+ years of software engineering experience, with at least 2 years building and operating LLM-powered or agentic systems in production - systems that ran, failed, and got fixed.

Production experience with at least one agentic framework (LangGraph, CrewAI, Autogen, Semantic Kernel, MCP, or comparable) and a clear understanding of the trade-offs each introduces.

Hands-on experience authoring MCP servers or designing tool-use APIs with explicit capability contracts and versioning.

Experience with agent memory architectures - context management, long-term memory stores, state persistence across multi-step workflows.

Strong fundamentals in Python and/or TypeScript; able to own production agent code from design through operation.

Proficient in prompt engineering, tool/function calling, and multi-step orchestration - and fluent in the failure modes of non-deterministic systems.

Working knowledge of RAG patterns, vector databases, and LLM evaluation methodologies applied to production agent outputs.

Working knowledge of AI/ML safety engineering: OWASP LLM Top 10, prompt injection defenses, RAG hardening, adversarial agent testing.

Preferred Qualifications

Pharma, life sciences, or healthcare data experience is a plus - not a requirement.
