[Hiring] Senior Full-Stack AI Engineer @Jouster

Role Description

DeepLaw is building an intelligent AI agent that reviews contracts — not just for legal risk, but through a business lens. Our goal is to help founders, operators, and legal teams understand what a contract actually means for them: the assumptions it relies on, what trade-offs it reflects, and how it aligns (or conflicts) with their values and goals.

We're looking for a Senior Engineer to lead technical development from scratch. You’ll build the agent system, connect the pieces (UI ↔ LLM ↔ data layer), and work closely with the founding PM to define the product and roadmap.

What You’ll Build

• The core AI agent pipeline — likely involving prompt orchestration, retrieval (RAG), and fine-tuning
• UX and tooling for interacting with the agent (basic web UI, annotation, structured contract data)
• Data + model infrastructure to support iteration and experimentation
• MVP features: assumption mapping, contract diagnostics, value-aligned feedback, etc.
• Deployment setup for a working prototype (CI/CD, cloud infra, minimal ops)
• Help define what “value-aligned” contract review actually means in product and code

Qualifications

• 5+ years of experience as a full-stack engineer or AI engineer, ideally at startups
• Experience with LLMs in production: prompt engineering, LangChain, AutoGen, or similar
• Familiar with agent-based architectures and RAG pipelines
• Comfortable spinning up web apps, APIs, vector stores, and fine-tuning loops
• Bonus: experience with legal tech, working with contracts, or interest in reasoning-focused AI
• Collaborative, autonomous, and energized by zero-to-one product challenges

Why This Role Is Unique

• Work on a real-world application of LLMs that goes beyond summarization
• Partner directly with a product-minded founder from day one
• High autonomy, fast decisions, greenfield architecture
• Influence not just what we build — but how we work and who we hire next

You’ll Probably Touch…

• OpenAI, Claude, open-source models
• LangChain / AutoGen / or a roll-your-own agent layer
• Pinecone, Weaviate, Postgres, Supabase
• React/Next.js or equivalent for UI
• GCP, AWS, Vercel, or lightweight infra for fast iteration
