Senior AI/ML Engineer: LLM Orchestration & Scalable Backend

Vertisystem (A MOURI Tech Company); United States; Sur place; USD 138 000 - 141 000; Plein temps

Résumé du poste

Vertisystem (A MOURI Tech Company) in the United States is seeking a Senior AI/ML Engineer to architect high‑throughput LLM agent orchestration and MCP integration for tax and compliance products. You will design asynchronous backends using Python, asyncio and FastAPI, implement evaluation benchmarks, gating, and multi‑tenant IAM‑DS entitlement for reliable, audit‑defensible execution.

Join a production‑oriented team focused on performance, observability with Datadog and OpenTelemetry, and

Qualifications

• 5+ years of software engineering experience in Python with high-throughput asynchronous services.
• 2+ years of hands-on experience building production LLM applications, agentic workflows, function calling, tool use, and multi-agent interaction protocols.
• Solid understanding of Model Context Protocol (MCP), RESTful API design, Agent-to-Agent orchestration, and Knowledge Graph/RAG patterns.

Responsabilités

• Agent Orchestration & Backend Development: Design, implement, and optimize multi-agent orchestration workflows (A2A), prompt templating, dynamic intent routing, and conversation memory using Python, asyncio, and FastAPI.
• MCP & Tool Integration: Standardize and integrate MCP servers and tools across Client’s products (AvaTax, Returns, Tax Research, ECM, Licensing).
• Evaluations & Benchmarking: Build automated evaluation pipelines (LLM-as-a-judge, deterministic assertions, harness evals) to benchmark agent intent accuracy, routing precision (HSR/FSR), and execution latency.
• Gating & Entitlement Routing: Implement dynamic cohort-based feature gating and IAM-DS entitlement evaluation to support controlled beta rollouts and multi-tenant access controls.
• Performance & Reliability: Optimize token consumption, response streaming, context caching, rate-limiting, and error handling for high-concurrency agent interactions.
• Production Readiness & Observability: Build telemetry pipelines, structured logging, and monitor dashboards across Datadog, Snowflake, and Open Telemetry to track model accuracy and system health.
