Senior Technical Writer
About the role
We're seeking a Senior Technical Writer to create clear, accurate, and developer-friendly technical documentation that transforms complex API specifications and code into comprehensive guides. This role bridges engineering and documentation, specializing in API reference documentation, integration guides, and code-to-doc workflows using industry standards like OpenAPI Specification (OAS). The Senior Technical Writer produces high-quality content deliverables including API reference documentation, SDKs, how-to guides, tutorials, and code examples.
