Lifescience-Logistics; Dallas (TX); On-site; USD 120,000 - 180,000; Full time

Job summary

Lifescience Logistics in Dallas, TX seeks a skilled prompt engineer to establish a structured prompt library and optimize LLM workflows across the organization. You will design RAG pipelines, test prompts for safety, and collaborate with Engineering, Product, and Compliance teams to deliver reliable AI-enabled solutions.

The role requires hands-on experience with Claude/GPT-4, strong technical writing, and a production mindset to improve workflows, latency, and cost.

Qualifications

• 3+ years of software engineering or applied AI experience, with at least 1 year focused on LLM prompt engineering.
• Hands-on experience with Claude, GPT-4, or similar large language models in production or near-production settings.
• Background in technical writing, UX wireframing, instructional design, or developer advocacy.
• Experience with adversarial prompt testing, red teaming methodologies, or AI safety evaluation frameworks.
• Production deployment mindset. You monitor what you build, you own uptime, you care about latency and cost.
• Previous experience working with a lean team in a regulated industry, such as pharma, healthcare, government, or financial services is preferred.
• Excellent written communication skills; ability to translate complex technical concepts for non-technical audiences.
• Proven ability to collaborate cross-functionally across engineering, product, and customer-facing teams.

Responsibilities

• Establish and maintain a structured prompt library for the company which will cover common use cases (summarization, Q&A, extraction, code generation, file analysis).
• Apply advanced prompting techniques including chain-of-thought, few-shot examples, role specification, and XML-structured inputs.
• Design and build RAG pipelines connecting our WMS, EDI logs, SOP repositories, contract data, and other systems.
• Deploy and tune LLM-powered applications including internal knowledge assistants, client-facing chat, extend RAG based response repositories, and leverage AI to optimize workflows, processes, and drive system improvements.
• Continuously A/B test prompt variants and document performance benchmarks.
• Serve as the subject-matter expert on Claude Desktop's file-handling capabilities, including referencing local PDFs, Word documents, spreadsheets, and code files within prompts.
• Create reusable prompt patterns that work reliably with multi-file inputs, long-context documents, and structured data.
• Champion prompt engineering best practices across internal teams including Operations, Control Tower, Business segments, and General Counsel to translate business problems into AI solutions.
• Embed PII handling rules, data residency constraints, jailbreak resistance, and refusal behavior guardrails into production prompt workflows.
• Test for prompt injection risks specific to local file inputs — including malicious content embedded in PDFs, DOCX, or CSV files uploaded through Claude Desktop.
• Build and maintain internal evaluation harnesses to measure prompt quality, consistency, and regression over model updates.
• Other duties as assigned
