Senior Full-Stack Engineer (Next.js / AI)

About Us Acquisity builds the platform that helps entrepreneurs and agencies automate sales and marketing with AI. We've grown from $0 to multi-8 figures in under 3 years and are scaling toward 9 figures. Our flagship product is used by thousands of teams daily. ~20 people, remote, no bureaucracy. The Work You'll build autonomous AI agents and multi-step LLM workflows that automate complex tasks for thousands of sales and marketing teams. Every project is greenfield. There is no legacy code. Our 8-person engineering team is currently building: - Autonomous agents that reason through multi-step tasks with planning, tool use, and memory - Real agent architecture, not just API wrappers - An operational platform (dashboards, workflow automation, client management) used daily by thousands of teams to run their businesses - LLM-powered onboarding and personalization pipelines that adapt to each user's business context You'd own features end-to-end: design conversations with product, build in Next.js (App Router) + tRPC, ship to production, and see real users benefit from what you built - often within the same week. How We Work: - AI-first development. Cursor, Claude Code, OpenCode, Codex and Devin are standard tools on this team. Parallel worktrees, RAG implementations, pgvector - if you're already building this way, you'll feel at home. - Trunk-based development. Small PRs, fast merges, rapid user feedback. No month-long feature branches. - Technical leadership. Our CTO writes code daily and manages engineers directly. You'll work with someone who understands the architecture and can pair on hard problems. - Ship and iterate. Working prototype in hours beats perfect spec in weeks. We're not precious about code - if something isn't working, scrap it and rebuild.
