Founding Full Stack Engineer

Founding Engineer (AI Agents + Frontend Craft)

Location: Remote (U.S.) — strong preference for NYC | 4+ hours overlap with Eastern Time daily Compensation: $180,000–$220,000 base Equity: 0.2%–0.5% Visa: No new sponsorship (H1B transfers and TNs only)

About Our Client

Our client is building AI infrastructure for trial attorneys. The goal is simple (and high-stakes): deliver AI output reliable enough to be used in litigation workflows where accuracy, traceability, and defensibility matter. They're a small, fast-moving team (4–5 people) looking for a founding engineer who can ship product quickly while building the agent systems and evaluation loops that keep quality high.

The Role

This is a high-ownership, high-range founding role. You'll own frontend craft for the primary AI interface and go deep on agent architecture—orchestrators, sub-agents, tool-use patterns, and evaluation loops. You'll move between polished UX work and core agent infrastructure, often in the same week (sometimes the same day). If you thrive in early-stage environments and want to build a product where correctness is non-negotiable, this role is built for you.

What You'll Do

• Build and ship across the full stack—React, Next.js, TypeScript, backend services, and AI systems—often within the same day
• Own third-party integrations end-to-end (scoping → implementation → deployment), including tools like Clio, iManage, Salesforce, and others
• Collaborate closely with a small team of full-stack and data engineers to improve system stability, performance, and delivery velocity
• Develop AI-powered features for litigation workflows, including: document extraction, agent orchestration (orchestrators + sub-agents), RAG pipelines, anti-hallucination scaffolding and reliability guardrails
• Contribute to backend optimization and system upgrades to improve reliability at scale
• Move fast when issues arise—this is a startup where adaptability and urgency are part of the job

What Our Client Is Looking For

• Strong full-stack fundamentals with excellent frontend craft (React/Next.js/TypeScript)
• Practical experience building agentic systems or strong interest with the ability to learn quickly: tool-use patterns, orchestration, retrieval, and eval loops
• Experience owning integrations with third-party APIs and systems (auth, rate limits, edge cases, monitoring)
• A "ship it" mindset: you can iterate fast without sacrificing quality and you can explain what you built
• Comfortable in ambiguity and excited by early-stage ownership
• Strong communication skills—clear, direct, and collaborative

Compensation & Equity

• Base salary: $180,000–$220,000
• Equity: 0.2%–0.5% (founding-hire level ownership)

Location & Work Authorization

• Remote U.S.-based, with strong preference for NYC
• Eastern Time overlap: 4+ hours daily
• No visa sponsorship (H1B transfers and TNs only)

Interview Process

1. Intro Call (20–30 min): founders assess communication style, startup readiness, and how you work day-to-day (no technical evaluation)
2. Take-Home Challenge: timed coding exercise + Loom walkthrough explaining approach and decisions (tests shipping ability and self-auditing)
3. Technical Deep Dive (60 min): live walkthrough of take-home with founders—tests depth of understanding, decision-making, and ability to defend tradeoffs
