Remote — New York, NY (HQ)

Full Stack Developer

Full-time · Remote (US hours overlap)

Join Harakumo early and own whole services 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.

What you'll do

Ship entire services 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

Apply

Applications are reviewed only through this form. Required: your GitHub/portfolio and a link to something you built on Harakumo (sign up free, create an API key, use the SDK or CLI — even a 20-minute demo counts).
