Job Description

We're a seed-stage AI automation company building the control plane that lets businesses design, deploy, and manage intelligent back-office workflows. Think visual workflow builders, real-time observability dashboards, and hybrid interfaces that serve both technical and non-technical users — layered on top of enterprise ERP systems. We recently hired a designer. Now we need the engineer who executes. This role owns the frontend control plane UI — the surface our customers live in every day. You'll work directly with founders, ship fast, and have a significant say in how the product looks and behaves. This is a hybrid role. We're opening an office in Union Square and expect engineers in the office a few days per week. Remote-only candidates will not be considered.

Job Responsibility

  • The core control plane UI — workflow authoring, agent configuration, task management, and human-in-the-loop approval surfaces
  • Reporting and observability dashboards for workflow performance and analytics
  • Real-time data sync layers using WebSockets and Server-Sent Events
  • Adaptive interfaces that serve both technical operators and business users
  • API integrations in close collaboration with backend engineers

Requirements

  • 4–7 years of full-stack experience, strongly frontend-weighted (60–80% UI work)
  • Expert-level React with TypeScript — production-grade, recent, modern patterns
  • Proven experience building complex interactive UIs: dashboards, workflow builders, visual editors, data-rich applications
  • Modern CSS proficiency — Tailwind preferred
  • Full-stack integration experience: building and consuming APIs, collaborating with backend
  • Product mindset — you care about how things feel and function, not just whether they ship
  • NYC-based or genuinely willing to commute to Union Square a few days per week
  • Existing US work authorization required — visa sponsorship is not available

Nice to have

  • Real-time UI experience: WebSockets, SSE, collaborative editing
  • Background at a workflow builder, no-code/low-code, or visual editor company (Retool, Airtable, Notion, Zapier, Monday.com, etc.)
  • Enterprise SaaS or B2B tooling exposure
  • Early-stage startup experience (seed through Series B)
  • State management library depth: Zustand, Redux, or Recoil

What we offer

  • Founding team equity at a well-backed seed round
  • Small team (~16 people), direct founder access, and real ownership of a critical product surface from day one
