Pay Rate - $50-60/Hr

Location:

Dallas, TX / Hybrid Duration: 6 months

Build and scale a production multi-agent AI platform serving thousands of internal users across multiple business units. Monthly release cadence, real users, real latency, real cost.

LLM-driven orchestrator that routes user intent across a portfolio of specialized agents — delegation, memory, response validation, capability discovery.

Agent selection layer — hybrid retrieval (vector RAG over a capability registry) plus closed-set LLM selection with JSON-schema-constrained outputs.

Multi-agent SDK / gateway — FastAPI service hosting many agents behind path-prefix routing, per-agent tool registries, session-scoped conversational context.

Tool-driven agents — 15–30 tools per agent composed dynamically by an LLM; owns tool contracts, guardrails, and evaluation.

Data API layer — parameterized endpoints between agents and databases; LLMs never touch DBs directly.

Partner-team onboarding — versioned A2A contract, bring-your-own-agent registration, auto re-embedding.

Production LLM systems: RAG, tool/function-calling loops, structured outputs, hallucination guards, closed-set selection.

Multi-agent orchestration: A2A protocols, session affinity, human-in-the-loop gating, kill switches, graceful degradation.

Vector search + embeddings at scale (sub-second retrieval over thousands of docs).

Evaluation & safety: PII/PHI masking, audit trails, feedback-loop instrumentation, offline + online eval.

Python 3.11+, FastAPI, async I/O, Pydantic.

Modern LLM stacks (Gemini, GPT, Claude) and agent frameworks (Lang Graph, Agent SDKs).

Cloud (GCP or AWS):
Kubernetes, object storage, workflow orchestration, Vertex/Bedrock-class services.

Redis, MongoDB, Oracle/Postgres, SSO + RBAC.

Observability:
Prometheus, structured JSON logs, per-decision audit trails, p95 latency SLOs in seconds.
