Role: Senior AI Engineer Agentic Systems (Contract)
Duration: Through 3/31/2027 could be extended
Location: 5 days onsite Plano TX
Overview:
Currently building AI agents that serve millions of customers directly. This is not a chatbot bolt-on or an innovation-lab experiment: our agentic platform sits in the production path of real customer conversations with the reliability latency and safety bar that implies. Were engaging senior engineers who have actually shipped agentic systems people who have felt the difference between a demo that works and an agent that survives contact with real users. Youll join a small senior team moving at startup pace with enterprise-scale distribution.
Responsibilities:
- Design and build production agentic workflows for customer-facing use cases multi-turn conversation tool calling retrieval escalation and human handoff.
- Own agent orchestration end to end using LangGraph/LangChain (or equivalent frameworks) including state management guardrails and failure recovery.
- Integrate agents with our core service layer: existing Java/Spring microservices APIs and event streams are the hands and feet of every agent you build.
- Build and tune the evaluation loop automated evals regression suites trace analysis and A/B measurement of agent quality.
- Work on the inference and serving layer: model routing prompt/context management and self-hosted serving with vLLM alongside commercial LLM APIs.
- Harden everything for a regulated high-trust environment: PII handling auditability deterministic fallbacks and observability.
- 7 years of software engineering experience with senior/lead-level ownership of production systems.
- Proven hands-on delivery of LLM-based agentic systems in production not coursework not POCs. Expect to walk us through architecture failure modes and eval strategy of something you shipped.
- Strong Python (primary agent/ML stack) and Java (service integration) both are daily-use languages here.
- Depth in the standard agent stack: LangChain LangGraph prompt/context engineering tool/function calling RAG pipelines.
- Working knowledge of PyTorch and model fundamentals enough to fine-tune debug model behavior and reason about tradeoffs.
- Experience with LLM serving/inference vLLM or comparable (TGI TensorRT-LLM) plus commercial APIs (OpenAI Anthropic Bedrock/Vertex).
- Solid distributed-systems fundamentals: APIs queues caching observability CI/CD.
- Hands-on experience with agent-builder platforms such as Sierra or Decagon deploying extending or evaluating them for customer-service use cases.
- Voice agents real-time/streaming inference or contact-center integration.
- Experience in regulated industries (finance healthcare) model risk compliance review audit trails.
- Eval frameworks (LangSmith Braintrust custom harnesses) and LLM safety/guardrail tooling.
