Machine Learning / AI Contractor: 10+ years (Expert)

Mindlance is seeking an expert Machine Learning / AI Contractor to build production-grade AI agents for customer-facing use cases at enterprise scale. The role involves designing agentic workflows, integrating agents with Java/Spring services and event streams, developing evaluation and inference systems, and ensuring reliability, safety, auditability, and observability in a regulated environment.

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

Preferred

• 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
• Agent-builder platforms

Qualifications

• 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
