Senior Claude Code Engineer (Pure Equity + Claude Max on us)

We're building the infrastructure layer for B2B GTM. Think of us as what comes after Clay - a sheetless intelligence and orchestration layer for GTM teams. We have a live product, real revenue, and are currently raising. I'm Ivan Kovpak, founder/CEO. Serial entrepreneur, once featured in Forbes, drove $1M in daily sales. I'm looking for a senior engineer who ships at AI speed. Why this role is different from every other startup job: We've already architected everything. 17 detailed product specs. Full Supabase schema. Every API endpoint defined. Every Edge Function contracted. Full dependency graph with task-level execution plan. Claude Code is our primary development tool - not a nice-to-have. You're not joining to "figure out the architecture." You're joining to execute at extreme velocity from detailed specs, using Claude Code 10-12 hours a day. What you'll own: unstuck-app - Next.js SPA (shadcn/ui + Tailwind, generated with v0 + Magic Patterns) unstuck-n8n - n8n workflow modifications and signal source integrations External connectors - destination adapters (Instantly, HeyReach, Salesforce via Ampersand, 60+ total) AI Copilot - CopilotKit integration with Claude API Supabase (Postgres + Edge Functions + Auth + Realtime), Next.js, n8n, Stripe, CopilotKit, Cloudflare Workers, PostHog, Upstash Redis, shadcn/ui, Tailwind, TypeScript What I need from you: You live in Claude Code. Not "I've tried it." You spend 10+ hours/day in it. You know the shortcuts, the slash commands, the MCP ecosystem. You've shipped real products with it. This is non-negotiable. You can execute from specs. I'll hand you a detailed spec with exact inputs, outputs, schema, and contracts. You ship it. Completely. First time. No "I'll add error handling later." You're a full-stack builder. TypeScript, React, SQL, APIs — you build across the stack. You're comfortable with n8n workflows, Supabase Edge Functions, and Next.js in the same day. You work at startup intensity. 10-12 hours/day, 7 days/week. This is a race to $1M ARR. If you need work-life balance advice, this isn't for you. You accept equity-only compensation. We pay for your Claude Max subscription ($200/mo). Everything else is equity. You need personal runway to sustain this until our Seed round. This is a co-builder role, not an employee role. Location: Los Angeles / West Coast strongly preferred. Remote possible if you're in overlapping US timezone. What you get: Meaningful equity in a company with revenue, product, and a raising round Complete product specs - you know exactly what to build before day 1 Working directly with the CEO - no layers, no politics Building a product in the hottest category in B2B (GTM infrastructure + AI) This is for you if: You've built and shipped with Claude Code, not just experimented You want ownership, not a paycheck You think in days, not sprints This is NOT for you if: You need a salary from day 1 You prefer to work 40-hour weeks You want to debate architecture endlessly before writing code You've never used Claude Code in production #J-18808-Ljbffr Unstuck Engine
