• Contribute to the development of commerce solutions capable of supporting high-load and distributed environments.
• Take ownership of technical initiatives from design through execution, ensuring projects are delivered against agreed priorities and business objectives.
• Partner closely with product managers and stakeholders to translate business needs into effective technical solutions and challenge requirements when a different approach would create greater user or business value.
• Apply sound architectural principles, including Domain-Driven Design (DDD), CQRS, and distributed systems patterns, to build maintainable and resilient services.
• Participate actively in code reviews, refactoring, testing, debugging, and pair programming to maintain high engineering standards.
• Identify and prioritize bugs, performance issues, and platform improvements, taking ownership of their resolution.
• Monitor and optimize application performance, reliability, and overall system quality.
• Contribute to a culture of continuous learning through technical knowledge-sharing sessions, mentoring, and best-practice discussions.
• Use AI and LLM-based development tools thoughtfully to support architecture exploration, implementation, testing, debugging, documentation, and code quality.

• 5+ years of professional back-end development experience, with strong proficiency in either PHP or Node.js and a willingness to develop expertise in the other.
• Strong knowledge of high-load architecture, distributed systems, Domain-Driven Design (DDD), and CQRS.
• Solid understanding of software engineering principles and best practices, including SOLID, TDD, CI/CD, Agile development, and automated testing.
• Professional experience with technologies such as PHP 8.1+, Symfony, Laravel, Yii2, Doctrine, or PHPUnit, or comparable back-end technologies.
• Experience working with databases and infrastructure such as MySQL, PostgreSQL, MongoDB, Redis, AWS, Kubernetes, and Docker is highly relevant.
• Strong debugging, testing, troubleshooting, and application-performance optimization skills.
• Comfortable working with modern engineering and observability tools such as Git, GitLab/GitHub, Grafana, Kibana, Prometheus, and Postman.
• Practical experience using LLMs and coding assistants, including tools such as Claude or GitHub Copilot, as partners for problem-solving, architectural brainstorming, coding, testing, and development workflows.
• Strong product mindset, with the ability to prioritize work based on business and customer impact rather than technical preference alone.
• Demonstrated ownership, critical thinking, adaptability, and ability to operate effectively in a rapidly evolving environment.
