Job summary

Highnote in San Francisco is seeking a Senior Technical Writer to own developer documentation for card issuing, acquiring, and money movement. You will define voice and standards, and build tooling to keep content aligned as the platform grows.

You will work with engineers, PMs, and the Developer Experience team, shipping API docs, guides, and tutorials. Strong writing for developers and experience with AI-backed tooling are highly valued.

Qualifications

• 5+ years across technical documentation and software.
• Docs-as-code: Markdown/MDX in a static site generator with git versioning.
• Comfortable working like an engineer: branches, pull requests, CI.
• Hands-on experience building AI-backed documentation tooling.
• Editorial instinct sharp enough to encode rules for machines.
• Ability to read an API schema and write valid requests in GraphQL; REST/OpenAPI is a foundation.
• Strong writing for a developer audience.

Responsibilities

• Own our API documentation — reference, developer guides, and tutorials
• Collaborate with the engineers who build the API and support the PMs
• Set voice, tone, and style of our docs and encode that standard into tooling
• Build and refine AI workflows that draft, review, and keep docs in step with the API
• Treat AI agents as a first-class audience alongside human developers
• Structure the documentation so it scales as the product grows
• Define how we measure documentation quality and use it to decide what comes next
