Backend & Automation Developer - Full-Time, Long-Term

We're a US-based technology consultancy. We build custom operations portals, backend automations, and AI-powered tools for our business clients. We're growing and hiring full-time developers. This is a long-term seat, not a one-off gig. What you'll do * Build and maintain API integrations (REST/JSON, JWT auth) with third-party platforms * Set up and manage Supabase: schema design, Row Level Security, auth, edge functions * Deploy and maintain apps on Vercel (Next.js API routes and serverless functions) * Build n8n workflows: scheduled syncs, webhooks, data pipelines, and automation flows for client projects * Build and harden Playwright browser automation bots in Node/TypeScript (logins, session persistence, file downloads, error recovery) * Integrate LLM APIs for document comparison and data extraction * Write clear documentation for everything you build. This is a job requirement, not a nice-to-have. Must have * Strong Node.js and TypeScript * Real Supabase experience (Postgres, RLS, auth) * n8n experience. * Playwright or Puppeteer automation against real-world sites you didn't control * Solid REST API integration experience * Clear written English. You must be able to explain your work in plain language. * Availability: we prefer someone who works US Eastern business hours. Or at least some of the hours should overlap. * Full-time availability (40 hrs/week). This role is not compatible with juggling multiple other clients. Nice to have * Next.js frontend experience * Experience working directly with a founder or very small team Hiring process * Short application (see below) * Video interview * Paid test project * Full-time engagement How to apply Start your proposal with the word PORTAL so we know you read this. Then answer these four questions. Short, specific answers beat long generic ones. * Describe one n8n workflow you built end to end. What did it do, and what broke along the way? * Describe one Playwright or Puppeteer automation you built against a site you didn't control. How did you handle logins, sessions, and file downloads? * Share a link to or sample of technical documentation you wrote. * What are your available working hours in US Eastern time? Proposals without the keyword or the four answers will not be considered.
