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.

Requirements

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.

The Stack:

• Next.js (App Router),
• tRPC
• TypeScript
• Tailwind CSS
• shadcn/ui
• Postgres
• Vercel
• Vercel's AI SDK for multi-agent workflows and LLM integration

What We Are Looking For:

Must-haves:

- 4+ years shipping production React/Next.js and TypeScript

- Experience owning full-stack features from idea to deploy

- Comfort with Postgres and serverless infrastructure (Vercel, Cloudflare)

- You've built something real with LLMs - not just played with ChatGPT

Strong signals:

- AI coding tools (Cursor, Claude Code, OpenCode) are already part of your daily workflow

- You've built multi-agent systems, RAG pipelines, or LLM-powered features

- You understand embeddings, vector search, or agent architecture at the technical level

- You ship fast without shipping garbage

We don't care about:

- Where (or whether) you went to school

- Your ability to invert a binary tree on a whiteboard

Benefits

Comp & Benefits:

- $140K - $180K base (based on experience)

- Fully remote - work from anywhere

- Small team, real ownership, zero red tape

- Direct product impact visible within days, not quarters

- Technical leadership that actually understands your work

Apply

Short application, no cover letter. If you look like a fit, you'll have a technical conversation with one of our engineers within a week.
