Harakumo

Job Description

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

Apply on this site. Every application goes through the form on the role’s page. Email and LinkedIn messages are not reviewed.
Show, don’t tell. Sign up at harakumo.com, build something small with the SDK or CLI, and link it. We read code before résumés.
One conversation. 45 minutes with the founder about what you built and what you would build here.
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.
