Senior LLM Workflow Engineer ( See Application Requirements)

• *Senior LLM Workflow Engineer (Contract)** LangChain, Tool Orchestration, Production Systems • *Description** We are a small, execution-focused team building production LLM workflows for real business use cases, including document processing, extraction, reasoning, routing, and validation. We are looking for a senior engineer to help design and implement robust, fault-tolerant LLM systems. This is not a research role and does not involve model training or fine-tuning. This work sits at the intersection of software engineering, LLM orchestration, and systems design under uncertainty. --- • *What you’ll work on** Designing and implementing end-to-end LLM workflows, such as: • document classification and task routing • prompt-based extraction to structured JSON • schema validation, retries, and fallback strategies • orchestrating LLM tool calls (web search, retrieval, function calls, external APIs) • managing intermediate state across multi-step chains • logging, observability, and debuggability • simple human-in-the-loop review hooks This role focuses on building reliable systems around unreliable components. Tools may include (depending on the system): LangChain or similar orchestration frameworks, OpenAI or Anthropic APIs, Python, lightweight persistence layers, and simple evaluation or testing harnesses. --- • *What this role is NOT** This is not an ML research or model training role and is not focused on prompt experimentation in isolation. If your primary interest is novel model work, this will not be a good fit. --- • *What we’re looking for** • *Required** • strong software engineering fundamentals • experience building multi-step LLM workflows or LLM-backed systems in production • experience orchestrating tool-using LLMs (retrieval, function calls, external APIs) • comfort designing control flow, retries, validation, and fallbacks • good judgment about simplicity vs over-engineering • ability to ship independently and explain tradeoffs clearly • *Nice to have** • experience hardening brittle LLM systems • experience with document processing or extraction • experience working under ambiguous requirements and tight timelines • prior startup or early-stage experience • *How to apply** Please include: • a brief description of a real LLM workflow you’ve built (not a demo) • your experience with LangChain or similar orchestration tools • an example of how you’ve handled LLM failure or brittleness • your hourly rate and availability over the next 2–3 weeks Optional but helpful: GitHub or code samples. --- • *Why work with us** • real production problems, not toy projects • small team with fast decisions • direct interaction with the founder • high trust and low process overhead • clear scope and expectations --- Apply tot his job
