Description

We are seeking an AI Engineer to design, build, and ship the AI-powered features that sit at the heart of the Lexapar platform. A core part of this role is building and owning the model harnesses that let the team develop, test, and compare AI systems with confidence with the evaluation suites, agentic/tool-use scaffolding, and production instrumentation that turn frontier model capability into reliable, shippable features. You will work closely with product, engineering, and legal domain experts to translate real legal workflows into AI-driven product experiences that meet the accuracy and reliability bar the profession demands.

What you’ll do

Model Harness Development: Build and maintain the harnesses that power model development at Lexapar, evaluation harnesses, agentic/tool-use scaffolding, prompt and context test beds, and regression suites that let the team run, compare, and validate models quickly and reproducibly. This is a major, ongoing focus of the role.
AI Feature Development: Design, build, and ship production features powered by LLMs and other AI models,



from prototype to scaled, reliable functionality within the Lexapar platform.
Retrieval & Agentic Systems: Build and optimize RAG pipelines, tool-use/agentic workflows, and orchestration layers that let models reason over legal documents and take multi-step actions reliably.
Prompt & System Design: Design and iterate on prompts, context strategies, and system architecture to maximize accuracy, consistency, and cost-efficiency across use cases.
Model Integration & Evaluation: Integrate best-fit foundation models (proprietary and open-source) into the product through the team’s harnesses, running structured evals to measure output quality, latency, and cost trade-offs before and after release.
Production Reliability: Own the AI layer end-to-end in production, monitoring, guardrails, fallback logic, and observability to ensure outputs meet legal-grade accuracy and reliability standards.
