Why we're hiring this role

Developers building on OneInbox is now one of our strongest top-of-funnel signals — but the experience hasn't kept up.
We have the raw API surface; we don't yet have the SDKs, samples, and content that turn a curious developer into a paying integration.
This role owns the first 5 minutes and the first 100K calls — both matter, neither is currently world-class.

What you'll be doing

First 30 days

Build with our APIs as a real developer would. Document every friction point.
Audit existing SDKs, docs,



and sample apps for accuracy, recency, and coverage.
Talk to 10 developers actively building on OneInbox and 10 who tried and dropped off.

First 60 days

Ship a refreshed quickstart in TypeScript and Python that gets a real call working in under 10 minutes.
Stand up a documentation pattern (concepts, how-tos, reference, recipes) — and start filling it.
Run the first OneInbox developer office hours and write the first 3 deep tutorials.

First 90 days

Own at least one SDK end-to-end and ship the next minor release.
Land OneInbox on the stage at a regional developer conference.
Define and report on DevRel metrics that map to revenue and platform stickiness.

Who you are

3+ years building developer tools, SDKs, or technical content that developers actually used.
Solid code — you can ship a non-trivial sample app in a weekend.
Excellent writing. A public body of work (blog, OSS, talks) is a major plus.
You read API docs
