Technical Writer

🚀 Zexter is an ambitious product building its own technological ecosystem in the iGaming space.

We are developing our in-house platform, which is already live and actively operating, while also expanding our product line, allowing us to adapt quickly to market needs and implement innovations at speed.

We are building a B2B iGaming platform and currently have no formal technical documentation. We need a Technical Writer to create the documentation foundation from scratch: internal and external docs, API references, operator guides, release notes, and knowledge base standards.

This is a hands-on role for someone who can work closely with engineering, product, QA, and business teams, extract knowledge from subject-matter experts, and turn it into clear, structured, and maintainable documentation.

Key Responsibilities

• Build the technical documentation function from the ground up: define structure, templates, style guides, glossary, and documentation standards.

• Create and maintain B2B client-facing documentation:

  • Operator and administrator guides for the platform back office.

  • Integration and API documentation for partners and internal teams.

  • Release notes, changelogs, and feature announcements.

• Create and maintain internal technical documentation:

  • Architecture overviews, technical specifications, internal APIs, and process guides.

• Work closely with developers, QA, product managers, and business stakeholders to collect and validate information.

• Maintain documentation as a product: version control, regular updates, review cycles, and knowledge base hygiene.

• Use tools such as Confluence, Jira, Markdown, Git, Swagger/OpenAPI, and Postman.

• Ensure documentation is accurate, consistent, and accessible to different audiences (developers, operators, management).

Requirements

• Proven experience as a Technical Writer, Documentation Lead, or similar role in a software product company.

• Experience writing API documentation and working with OpenAPI/Swagger or similar tools.

• Ability to understand software architecture and communicate effectively with engineering teams.

• Strong written communication skills: clarity, structure, and attention to detail.

• Experience with documentation tools: Confluence, Jira, Markdown, Git, and version control workflows.

• Ability to work independently in a fast-paced environment and build processes from scratch.

Nice to Have

• Experience in iGaming, online casino, sportsbook, or B2B platform environments.

• Understanding of B2B operator workflows and platform integrations.

• Experience with docs-as-code approaches and static site generators.
