This role centers on public REST APIs, embedded integrations, webhooks, SDKs, and AI-driven developer tools. The ideal candidate will be a proactive technical writer capable of independently grasping complex technical concepts, collaborating closely with engineers and product managers, and producing clear, comprehensive documentation that enables developers to integrate efficiently and effectively.

Key Responsibilities

- Own the information architecture, content strategy, and quality standards for the developer portal, including guides, API references, recipes, and release notes.
- Audit and enhance existing documentation by consolidating duplicate content, identifying gaps, retiring outdated information, and streamlining the path to a developer’s first API call.
- Develop clear and detailed integration guides for complex fintech workflows such as AP/AR payments and payment states, vendor onboarding and BILL Network, KYC/KYB compliance and verification, webhooks, and partner or embedded integrations.
- Collaborate with Product and Engineering teams to document new product launches, including OAuth, BILL Elements, MCP, and AI-related developer experiences.
- Create documentation from product requirement documents (PRDs), design files (including Figma), API specifications, and other technical resources.
- Maintain alignment and currency of OpenAPI specifications, Postman collections, code samples, and documentation.
- Optimize documentation for AI-assisted development by producing structured content, Markdown outputs, and files compatible with AI assistants and agents.
- Build and maintain partner-facing FAQs and self-service documentation to reduce repetitive support requests.
- Establish and uphold style guides, templates, documentation standards, and docs-as-code workflows.
- Work independently with engineers and product managers to gather technical information, clarify ambiguities, and ensure documentation accurately reflects the product.
- Prioritize documentation initiatives based on developer needs, product priorities, and business impact.

Required Qualifications

- Minimum of 7 years of technical writing experience, including at least 4 years focused on documenting public REST APIs for external developers.
- Proven track record of owning and improving developer portals or technical documentation platforms.

- Experience working with OpenAPI specifications.
- Familiarity with documentation platforms such as ReadMe, Mintlify, Docusaurus, or similar tools.
- Experience with Git-based documentation workflows.
- Excellent collaboration skills, able to work effectively with engineers, product managers, and other technical stakeholders.
- Ability to work independently, ask insightful questions, and challenge unclear or incomplete requirements.
- Strong organizational and prioritization skills to manage multiple documentation projects simultaneously.

Preferred Qualifications and Benefits

- Experience in fintech, payments, financial technology, or embedded finance sectors.
- Background in documenting SDKs, webhooks, or embeddable UI components.
- Experience incorporating AI tools into the technical writing workflow.
