Content Manager (AI & Automation Specialist)

Elbax is a fast-growing IT company building digital products without borders. Day after day, our team of experts works tirelessly to ensure our web and mobile applications don’t just meet—but exceed—user expectations.

The Role & Our Philosophy

We are looking for a Content Manager who is a virtuoso with AI tools and knows how to turn them into a powerful lever for high-quality content creation. We don’t require experience in a specific niche—what matters is your ability to "negotiate" with neural networks, your grasp of text structure, and your technical literacy when working with websites. If you know how to create engaging long-reads and automate multi-language translations, we want you on our team.

Key Responsibilities:

• Prompt Engineering & Content Generation: Create high-quality copy using AI frameworks (ChatGPT, Claude, etc.).
• Multilingual Localization: Prepare multi-language content using AI tools and perform final reviews with translation software.
• Web Publishing: Format and publish materials within the WordPress admin panel. Work with HTML markup to ensure perfect content display and site integrity.
• Content Optimization: Handle basic article styling (headers, lists, meta-tags) and image management.
• Quality Assurance: Conduct final proofreading to ensure generated content meets all specified criteria and brand standards.

Our Expectations:

• AI Power User: You can craft complex, multi-level prompts and understand how to get the desired output from a neural network on the first attempt.
• Technical Background: Knowledge of HTML (at a level sufficient for page code editing) and hands-on experience with WordPress.
• Writing Skills: Experience in creating long-form content. The ability to structure information so it is genuinely useful to the reader.
• Language Skills: English proficiency sufficient for prompting AI and quality-controlling automated translations.
• Versatility: A readiness to switch rapidly between different task types and content formats.

What We Offer:

• Technological Freedom: We encourage the use of any AI tools and services that make your workflow more efficient.
• Dynamic Start: A great opportunity to enter international projects and master the specifics of global markets.
• Zero Bureaucracy: Fast-paced processes, a focus on results, and transparent communication.
• Culture: A professional business approach, no micro-management, and a focus on long-term outcomes.
