What You'll Be Doing

The Senior Technical Content Designer (API) creates technical content primarily for developers and integration partners. You'll join a high-performing technical writing team, reporting to the Senior Manager, Technical Content. Your day-to-day partners include product managers, engineers, technical account managers (TAMs), and other teams across the organization.

• Write clear, accurate, well-organized documentation for a developer audience in Markdown and HTML, covering APIs, SDKs, integration guides, quickstarts, and workflow-oriented narratives.

• Design content architecture across orientation, decision, and implementation layers, ensuring different types of users (advertisers, providers, sellers) can find, understand, and act without relying on a TAM.

• Write with structure and precision that serves both human readers and AI-assisted workflows-clear information hierarchy, consistent terminology, and complete context at every entry point.

• Define and implement conditional content and tagging strategies, including persona routing, protocol dimensions (REST vs. GraphQL), and environment conditions.

• Update API and integration documentation in GitLab repositories using Git (branching, pull requests, merging to main).

• Contribute to content governance frameworks by defining ownership, freshness policies, and quality standards as the platform scales across federated contributors.

• Conduct UX and heuristic evaluations of the documentation experience; translate findings into concrete content and structural improvements.

• Collaborate with engineering on authoring toolchain improvements: reducing page replication, improving multi-portal support, and automating reference generation.

• Monitor and respond to user feedback to continuously improve content quality and coverage.

• Write end-user documentation and UI copy as needed.

Requirements

• Understanding of how well-structured, consistently written content performs better in AI-assisted search and retrieval-and the discipline to write that way by default

• Ability to evaluate documentation UX using established frameworks (such as heuristic evaluation, user journey analysis) and translate findings into actionable improvements
• Experience with or strong interest in content governance: establishing standards, ownership models, and scalability frameworks in multi-contributor environments

Writing & Communication

• Exceptional writing, editing, and critical thinking skills: you ask hard questions of SMEs, advocate for the reader, and can tell the difference between what's technically accurate and what's actually useful

• Familiarity with technical writing style guides and best practices (Microsoft Writing Style Guide, Google Developer Documentation Style Guide, or equivalent); experience applying or contributing to a team style guide

• Ability to develop cross-functional rapport with product managers, engineers, product marketing, account managers, and other stakeholders

• Ability to learn complex systems quickly and take responsibility for your assigned area

• Commitment to creating high-quality, accessible developer documentation experiences

Tools & Workflow

• Familiarity with project management and communication tools (Jira, Confluence, Slack)

• Experience creating technical diagrams (workflow, integration, entity) using industry-standard diagramming tools

• Familiarity with AI tools and AI-assisted documentation workflows

Soft Skills

• Self-starter with great attention to detail, strong time management, and sound decision-making

• Ability to manage multiple projects and handle frequent context-switching

• Comfortable working in ambiguity and advocating for content strategy decisions with cross-functional stakeholders

Education

Highly Desired

• Experience in digital advertising technology and programmatic advertising concepts

• Familiarity with OpenAPI Specification and API testing tools (such as Postman)

• Experience with developer portal platforms, docs-as-code pipelines, or content platform architecture

• Familiarity with content-as-infrastructure thinking: content layering, workflow-oriented documentation, guided user journeys

• Experience designing or auditing documentation for i18n readiness; familiarity with localization workflows or frameworks

• Experience working with autogenerated API reference alongside authored narrative content
