About Beliani

Beliani is an international e-commerce company selling furniture and home accessories. Founded in 2009, we operate in 21 markets and employ over 800 people.

Our Technology Department builds and runs our own e-commerce platforms and our in-house ERP system, Prologistics. We work AI-first: our developers code with AI tools every day, mainly Claude Code.

Your Responsibilities

• Develop and optimize Prologistics and our e-commerce websites across three areas: Logistics, Warehouse and Shop (orders, inventory, shipping, returns).
• Build and maintain REST APIs and integrations with internal systems, online stores and external services.
• Refactor legacy code and fix bugs and performance bottlenecks, including database queries.
• Deliver your work using AI coding tools (Claude Code) as your main way of working, and use voice typing for prompting and communication.
• Contribute to business process automation and AI-powered features.
• Work closely with developers, Tech Leads, Project Managers and business teams.

Our Requirements

Experience

• Middle: minimum 3 years of commercial PHP backend experience.
• Senior: minimum 5 years of commercial PHP backend experience.
• Your final level (Middle or Senior) is decided based on the technical interview.

Technical skills

• Strong PHP 8+ and object-oriented programming.
• Very good MySQL / MariaDB, including query optimization, views, triggers, procedures, functions.
• Experience with Nginx, Apache2, Redis, MongoDB and/or HAProxy.
• REST API development and integration; Git.
• Comfortable working in large custom codebases without standard PHP frameworks.
• Strong analytical, debugging and problem-solving skills.
• English good enough for technical documentation and teamwork.

AI way of working

• Hands-on experience coding with AI tools — ideally Claude Code — as your daily workflow, not an occasional helper.
• Ability to give AI tools clear context and instructions, review their output critically and take responsibility for the final code.
• Experience with, or willingness to use, voice typing tools — we use them as standard for prompting and communication.

Nice to Have

• MariaDB 11+.
• ERP, WMS or e-commerce experience; understanding of logistics and warehouse workflows.
• Docker, CI/CD and automated testing.
• Integrating LLMs or other AI services via API.
• Business process automation.

What We Offer

• Fully remote, full-time (40 h/week), long-term cooperation.
• Software Development Agreement, salary in USD or EUR.
• 20 paid working days off per year.
• International team working on a large custom ERP and multiple e-commerce sites.
• Kanban-based workflow with Agile/Scrum practices, task management and time tracking.
• Real impact on automation and AI projects, plus professional growth.

Recruitment Process

• General interview — your experience, expectations, and an introduction to Beliani and our projects.
• Practical test task — up to 8 hours, submitted within 3–5 days. Unpaid, used only to assess skills; not part of any commercial project and never used in production. No access to our source code is given. Using AI tools for the task is expected.
• Technical interview — with our Tech Lead: your task, architecture, databases and how you work with AI. This interview also determines your level (Middle or Senior).
• Final decision — feedback within two weeks of the technical interview.
