Senior PHP/Symfony Engineer — Integrations & Automation

We are looking for a senior PHP/Symfony engineer to help own and scale our internal business automation platform. This role is ideal for an engineer who has built and maintained complex integrations between ecommerce, ERP, CRM, and other business systems, and who enjoys solving challenging problems involving data synchronization, asynchronous processing, and production reliability.

You'll work alongside an existing developer to improve architecture, strengthen monitoring and error handling, and build reliable automations that support our ecommerce and sales operations.

Role Overview

The platform connects our ERP, e-commerce stores, and sales tools, keeping customers, orders, leads, and product data in sync. Your primary objective is to make it reliable, maintainable, and monitorable. Key focus areas are product architecture, data modeling, a Symfony backend with caching, queues, and asynchronous processing, integrations, crawling, and a React frontend. The ideal candidate is an experienced full-stack Symfony developer who has built integrations at scale, pays close attention to detail, learns fast, and enjoys solving problems creatively.

Responsibilities and Duties

• Own the architecture of our automation platform, keeping it maintainable, monitorable, and scalable.
• Design and maintain the data model behind customers, orders, leads, accounts, and products.
• Build and run daily sync chains between our ERP, ecommerce stores, and sales tools: customer and order sync, lead scoring, account assignment, and write-backs.
• Integrate with ecommerce platforms through GraphQL APIs, bulk operations, and webhooks, and with other systems through REST and SOAP.
• Keep syncs reliable despite rate-limited APIs and missing records, and protect write-back data quality.
• Build resilient browser automation with headless browsers in Node.js for workflows that have no API, and web scraping behind proxies.
• Enrich and categorize product data using AI models, controlling cost and accuracy.
• Run Symfony Messenger queues, cron jobs, and background workers, handling failed messages quickly.
• Keep production healthy with alerts, digests, and runbooks, and reduce alert noise.
• Build React frontend screens for internal users and automate sales engagement and SEO tasks.
• Raise unit and end-to-end test coverage and keep it running in CI.

Qualifications and Requirements

• At least 5 years of professional software development experience.
• A degree in computer science or a related field, or equivalent practical experience.
• Proven experience building and running integrations and automations with third-party APIs (ERP, ecommerce, CRM, and sales tools) at scale.
• Proven product architecture skills: designing and running maintainable, monitorable, scalable applications.
• Strong data modeling skills and deep experience with relational databases (e.g., PostgreSQL) and Doctrine ORM.
• Expert knowledge of PHP 8 and Symfony on the backend.
• Strong knowledge of caching systems (e.g., Redis).
• Hands-on experience with Symfony Messenger or other message queues, and with asynchronous and background processing.
• Experience with REST, GraphQL, and SOAP APIs.
• Experience with web crawling and headless browser automation (Node.js).
• Strong experience with a modern JavaScript frontend, ideally React.
• Automated testing experience, unit (PHPUnit) and end-to-end (Playwright), and CI/CD pipelines.

Personal Qualities

• Strong attention to detail.
• Creativity in finding simpler, better solutions.
• A fast learner who picks up new systems quickly.
• Hardworking, with real ownership of results.

Nice to Have

• Experience with ERP or ecommerce platform data models.
• Experience with sales engagement or CRM automation.
• Knowledge of SEO automation.
• Knowledge of foodservice equipment or the wider equipment supply industry.
