Senior AI Software Engineer

BriefCatch is the leading legal writing software trusted by top litigators, judges, and legal teams across the country. They are seeking a Senior AI Software Engineer to own meaningful parts of the product end-to-end, working across the full stack to shape technical direction and ensure high-quality engineering practices.

Responsibilities:

• Design and ship LLM-powered legal intelligence features with extremely high accuracy requirements
• Lead advanced prompt engineering and iterative tuning (CoT, few-shot, ReAct, structured outputs, self-verification) specifically tuned for legal accuracy
• Build and continuously improve RAG pipelines over large legal data points, including chunking strategies, embedding models, reranking, and domain-specific retrieval optimization
• Create rigorous LLM evaluation frameworks, automated regression suites, and human review workflows focused on citation correctness and legal reasoning quality
• Productionize AI components: integrate cleanly with backend services (Python/FastAPI + Syncfusion), implement guardrails, caching, fallback logic, cost/latency controls, and full observability for every LLM call
• Apply targeted fine-tuning (LoRA/QLoRA), quantization, and inference optimizations when they deliver clear gains in accuracy or economics for legal workloads
• Work shoulder-to-shoulder with systems engineers, legal experts, and product to turn promising AI experiments into reliable, auditable features that lawyers and judges can trust
• Track the fast-moving LLM landscape and bring pragmatic, high-leverage advancements into production while maintaining BriefCatch’s high bar for accuracy and safety in legal contexts
