Develop and maintain integrations with eCommerce platforms using GraphQL APIs, bulk operations, and webhooks, as well as REST and SOAP APIs for other business systems. - Improve synchronization reliability by handling API rate limits, missing records, failures, and data inconsistencies while protecting the quality and integrity of write-back operations. - Build and maintain browser automation workflows using headless browsers in Node.js for processes without suitable APIs, alongside web scraping solutions that may use proxy infrastructure. - Use AI models to enrich and categorize product data while balancing processing costs, accuracy, and operational efficiency. - Manage Symfony Messenger queues, scheduled jobs, background workers, and asynchronous processing, ensuring failed messages are diagnosed and resolved promptly. - Maintain production health through effective monitoring, alerts, operational digests, and runbooks while reducing unnecessary notifications and improving incident response. - Develop and maintain React-based interfaces for internal users and support the automation of sales engagement and SEO-related workflows. - Strengthen automated testing across the platform, including unit and end-to-end tests, and ensure reliable execution through CI/CD pipelines. - Collaborate closely with the existing developer, take ownership of technical outcomes, and continuously identify opportunities to simplify workflows and improve platform performance. ## Requirements - At least 5 years of professional software development experience, with substantial hands-on experience building applications using PHP and Symfony. - A degree in Computer Science or a related discipline, or equivalent practical experience. - Proven experience designing, building, and maintaining production integrations and automation workflows involving third-party systems such as ERP, eCommerce platforms, CRMs, and sales tools. - Strong software architecture skills, including the ability to design and operate scalable, maintainable, and monitorable applications. - Deep knowledge of relational data modeling and databases such as PostgreSQL, along with practical experience using Doctrine ORM. - Expert knowledge of PHP 8 and the Symfony framework. - Strong experience with caching technologies such as Redis. - Hands-on experience with Symfony Messenger or comparable message queue systems, including asynchronous processing, background jobs, and worker management. - Experience integrating systems through REST, GraphQL, and SOAP APIs, with an understanding of webhooks, bulk operations, rate limits, and reliable data synchronization. - Practical experience with web crawling, web scraping, and headless browser automation using Node.js and tools such as Playwright or Puppeteer. - Strong knowledge of modern JavaScript frontend development, ideally with React. - Experience writing and maintaining automated unit tests with PHPUnit and end-to-end tests with Playwright, as well as working with CI/CD pipelines. - Strong attention to detail, creative problem-solving skills, and the ability to learn unfamiliar systems quickly. - A proactive, ownership-oriented approach, with the ability to take responsibility for production reliability and deliver meaningful results. - Additional advantages include familiarity with ERP or eCommerce data models, CRM and sales engagement automation, SEO automation, or the foodservice equipment and commercial supply industry. - Ability to communicate effectively in a remote team and maintain regular working-hour overlap between 10:00 and 19:00 Paris time. ## Benefits - Fully remote work from anywhere within Europe. - Full-time position with working hours that overlap with the team between 10:00 and 19:00 Paris time. - Challenging technical work involving integrations, automation, data architecture, asynchronous systems, and AI-powered workflows. - The opportunity to shape and improve a business-critical platform used across daily operations. - A collaborative and professional working environment that encourages creative thinking, new ideas, and continuous development. - The opportunity to build meaningful working relationships and see the direct impact of your engineering contributions. -
