Posted about 13 hours ago

About the Company

Our client is an early-stage, San Francisco-based AI startup building the operating system for family law. Their platform automates the most time-intensive parts of legal practice — client intake, financial disclosures, document preparation, case management, and client collaboration — helping family law firms modernize and scale without adding headcount. Founded in 2025, the company is already working with real customers and actively closing a seed round, with $XM signed to date.

 

The Mission

To reduce the emotional and financial burden of divorce for millions of families — and empower the legal professionals who serve them — by transforming a fragmented, manual process into a guided, intelligent, AI-driven experience.

 

The Opportunity

This is a co-founder seat, not a hire.

You're joining at the inflection point: real product, real customers, seed round closing. As the first technical leader, you'll own the full stack — architecture, AI infrastructure, engineering culture, and execution velocity. You'll work shoulder-to-shoulder with the founding team to define how AI reshapes one of the largest, most underserved verticals in legal services.

If you've been waiting for a founding opportunity where the market is real, the mission matters, and the equity is worth the bet — this is it.

 

What You'll Do

  • Own and define end-to-end technical architecture of the platform

  • Write and ship production code daily alongside the founding team

  • Architect and scale AI agent infrastructure for legal workflows — billing, financial layers, document automation, collections, and client collaboration

  • Build and scale the engineering team from scratch — hiring, mentoring, and establishing culture

  • Partner with founders on product roadmap, fundraising narrative, and company strategy

  • Ensure security, compliance, and scalability of a document-heavy, regulated-industry platform

  • Drive rapid iteration cycles and maintain startup velocity through seed close and beyond

 

What You Bring

Must-Haves:

  • 8+ years of software engineering experience, with 3–5+ years in technical leadership

  • Deeply hands-on — you still write and ship production code regularly

  • Proven experience building AI-native, workflow-heavy, or document-centric SaaS products

  • Proficiency with modern AI/ML stacks: LLMs, RAG, and agentic frameworks (LangChain/LangGraph, OpenAI/Claude APIs)

  • Strong backend and cloud infrastructure expertise (GCP/AWS, Python, Node.js, Kubernetes)

  • Experience building engineering teams in a 0→1 environment

  • Based in the SF Bay Area or willing to relocate

  • Financially comfortable with a founder salary model during the build phase — equity is the upside

Nice-to-Haves:

  • Exposure to legal tech, compliance-heavy, or regulated-industry products

  • Experience with document automation platforms

  • Prior founding experience or early employee (1–50 person company)

  • Background at Big Tech or high-growth SaaS

  • Genuine interest in access to justice and modernizing legal services

 

Key Success Drivers

  • Builder-first — you ship fast, don't wait for perfect conditions, and take pride in what you launch

  • Full ownership — you treat the product and team like they're yours, because they will be

  • Systems thinker — you design for agentic workflows and automation, not just feature lists

  • Ambiguity-tolerant — you thrive in 0→1 environments without a defined playbook

  • Mission-aligned — you're genuinely excited about AI's role in transforming legal services

  • Speed over perfection — you iterate fast, learn faster, and course-correct in real time

 

Why Join?

Compensation & Equity:

  • 8-10% founder-level equity — significantly above market, reflecting a true founding relationship

  • Base salary: ~$4,000/month during the pre-seed phase, with a clear normalization trigger post-seed close

  • Upside is entirely equity-driven, structured for long-term wealth creation

What Makes This Rare:

  • Co-founder title and seat — not a VP/Director scope with imposed constraints

  • Real product traction and paying customers before you join

  • Seed round in progress: $XM already signed

  • Recognized by TechCrunch Disrupt Startup Battlefield and Stanford CodeX FutureLaw

  • Greenfield opportunity to define the technical foundation of a category-creating company

Interviewing Process

  • Intro Call

  • Level 1 — Technical Deep-Dive

  • Level 2 — Take-Home or Live Build Exercise

  • Level 3 — In-Person Co-Founder Day (half day, SF)

  • Reference Checks + Offer
