Legal AI Engineer

Broadfield is a global law firm that specializes in transactions and litigation. They are seeking a Legal AI Engineer to build AI-powered workflows and enhance legal operations by structuring legal knowledge and developing custom workflows for various legal processes.

What you'll do:

• Map and structure the firm's playbooks, litigation frameworks, and due diligence processes into reusable knowledge assets
• Build custom workflows, in particular for document-intensive work across practices — from due diligence automation and playbook-based markup review on the transactional side, to discovery analysis, case chronologies, and brief research on the litigation side
• Design the RAG architecture that grounds AI outputs in the firm's proprietary precedents, deal data, and case materials
• Establish the prompt architecture library, guardrails, and quality standards that every subsequent build will draw from, and collaborate with attorneys to define what constitutes good output

What they're looking for:

• Hands-on experience building with legal AI tools (Harvey, Legora, or equivalent) or LLM APIs (Anthropic Claude, OpenAI, or equivalent)
• Experience designing and implementing RAG pipelines — chunking strategies, embedding models, and retrieval optimization
• Familiarity with workflow automation frameworks (LangChain, LlamaIndex, or equivalent) for multi-step AI pipeline construction
• Ability to translate unstructured legal documents into structured, machine-readable knowledge assets
• Proficiency with prompt engineering at a production level — system prompt architecture, guardrails, output schema design, edge case handling
• Comfort working with APIs, JSON, Python, or equivalent scripting
• Builder instinct: you measure your tools' success by adoption, not by what you've shipped
• Speed and judgment: you know when to prototype fast and when to get it right
• Communication: you can explain what you built both to a partner and to a machine
• Ownership: you treat the legal operations system as yours
• Experience in a law firm, legal tech company, or professional services firm
• Built AI-powered workflows

Benefits:

• Eligibility for a discretionary bonus
