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.

We're looking for a Senior Django / JS Engineer with deep Django expertise and server-rendered frontend skills to take full ownership of the core web platform. Concretely: the Django backend, the REST API, the async job layer, the access-control model, and the dispatcher dashboard that operators rely on 24/7. You will work alongside the Lead and the CTO while taking ownership of the entire stack.
 

You own the platform end to end. Day to day: you build features from the core Django backend and REST API to the server-rendered dashboard and telemetry visualizations, using Celery, Redis, RBAC, and audit logging throughout the platform.
 

One thing to be clear about: commands issued through this platform reach live power plants. That is why access control and audit logging are must-haves here, not a checkbox.

What you'll do

• Develop and own the core Django application end to end: Django backend, REST API, server-rendered dashboard, async job layer, and access-control model
• Design and optimize ORM queries - and know what SQL your querysets actually produce
• Write and deploy migrations against live schemas without downtime
• Build and maintain the Celery layer: task design, periodic jobs, retries, idempotency, queue routing
• Build and maintain dispatcher-facing dashboards and telemetry visualizations
• Design and enforce the RBAC model across the full stack
• Build audit logging as a tamper-evident trail: who, what, when, from where, with what result
• Work in a Spec-Driven Development workflow, treating OpenAPI/Pydantic specifications as the source of truth for API contracts and UI state

Must have

• 5+ years of production experience with Django: This is the core of the role. The interview will go deep into:
  • ORM: Query optimization, select_related/prefetch_related, annotations, and deep understanding of generated SQL.
  • Migrations: Safe deployment on live schemas without downtime.
  • DRF: Serializers, viewsets, permissions, and versioning.
  • Django Internals: Signals, custom management commands, and leveraging the admin as a tool.
• 3+ years of production experience with Celery & Redis: Mandatory, not "used it once." Task design, periodic jobs (celery beat), idempotent tasks, retries, queue routing, and Redis strategies (cache invalidation, TTLs).
• RBAC & Audit Logging: Designing role models (dispatcher/operator/admin) on the principle of least privilege. Every command must be logged—who, what, when, result—as a tamper-evident audit trail for live power plants.
• Full-Stack UI/UX: You own the "face" of the EMS platform.
  • SSR-First: You are comfortable in a server-rendered Django environment (template inheritance, custom tags/filters).
  • Vanilla Fundamentals: Strong grasp of modern CSS (grid/flexbox) and semantic HTML.
  • Data Visualization: You must be able to implement or adapt charting libraries (amCharts/ECharts) to visualize time-series telemetry.
  • AI-Driven Frontend: You treat UI as a spec. You use AI to generate boilerplate templates and interactivity, allowing you to focus purely on the UX reasoning and complex data representation rather than manual DOM manipulation.
• Engineering Rigor:
  • PostgreSQL: Indexes, transactions, and reading query plans.
  • Testing: Pytest, writing testable code for views/serializers/tasks.
  • English: B1 (documentation, written communication).
• Spec-Driven Development (SDD): You treat specifications (OpenAPI/Pydantic) as the source of truth for both API contracts and UI state.
• Agentic Pipelines: Experience building or using agent-based workflows (e.g., CrewAI, LangGraph) to automate backend engineering, deployment, and UI boilerplate generation.

Nice to have

• Frontend & UX: amCharts (v5) expertise; HTMX / Alpine.js for SSR-friendly interactivity; experience with UI design tools (Figma/Sketch) for rapid prototyping; Tailwind / Bootstrap or building small design systems; Accessibility (WCAG) and dark-mode optimization.
• Backend & Infrastructure: FastAPI / Pydantic v2, asyncio; Docker / Docker Compose, CI pipelines; TimescaleDB or MongoDB.
• Domain & Standards: Industrial connectivity (OPC UA, Modbus); Energy domain (PV / BESS); Security-standard exposure (IEC 62443, NIS2).
