Compensation: $180,000–$220,000 base
Equity: 0.2%–0.5%

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
