Full Stack Developer

Join Harakumo early and own whole services from end to end — API, dashboard, SDK, CLI, docs — on a modern edge-serverless stack, shaping how developers build their entire stack with one API key.

Apply for this roleAll roles

What you’ll do

  • Ship entire services from end to end: route handlers, provisioning on our edge infrastructure (compute, storage, SQL, vector, KV, streaming), dashboard pages, SDK namespace, docs
  • Build the AI orchestration layer: an MCP server and agent tooling that can provision and wire Harakumo services from natural language
  • Own reliability: tests against the live platform, migrations on edge SQLite, observability, and incident response
  • Talk to developers, write docs and examples, and turn feedback into product

What you bring

  • Strong JavaScript/TypeScript and real production experience with Next.js (App Router) and serverless or edge runtimes
  • Comfort with SQL and data modeling; bonus for SQLite, Postgres, or vector databases
  • Experience integrating third-party platforms (payments, cloud APIs) and designing clean public APIs/SDKs
  • A bias for shipping: you have launched things, and you can show them
  • Bonus: MCP/agent tooling, developer-tools or infra background, open-source contributions

What we offer

  • Competitive salary and early-team equity (discussed in the first conversation)
  • Remote-first, async-friendly; quarterly in-person in NYC
  • Direct ownership — you will be the architect of several services, not a ticket-taker

How we hire

  1. Apply on this site. Every application goes through the form on the role’s page, with the live link of something you deployed on Harakumo. Email and LinkedIn messages are not reviewed.
  2. Build it, from your own account. Create a free account, build a working app around your own idea (connect your AI to harakumo.com/mcp, or use the CLI or SDK), deploy it, and submit it signed in at /careers/next-step. We read what you built before résumés.
  3. One conversation. 45 minutes with the founder about what you built and what you would build here.
  4. A paid project, if useful. Optional: a scoped, paid one-week project on a real service. Then an offer.

The same steps, for every role, are on the careers page.

Applications are reviewed only through this form. Required: your GitHub or portfolio, and the live link of something you built and deployed on Harakumo, like https://your-project.harakumo.app (sign up free and deploy it with the SDK, the CLI or your AI; even a 20-minute demo counts). A GitHub link is not accepted for this one.
