Magento Certified Developer for Ongoing Client Support (Part-Time, ~10 hrs/month)

We're looking for an experienced Magento Certified Developer (or higher) to join us on an ongoing, as-needed basis to provide backend-focused technical consulting and support for one of our clients. This client uses Magento as a backend/commerce engine integrated into their SaaS product — not as a traditional storefront. So this role is about APIs, data, integrations, and backend architecture, not theming or front-end storefront work. This is a part-time, recurring engagement — approximately 10 hours per month — not a full project build. Some months may be lighter, others may require more hours; we're looking for someone flexible and responsive who can be a reliable long-term technical resource. WHAT YOU'LL DO - Provide expert consulting on Magento's backend architecture, data model, and APIs (REST/GraphQL/SOAP) as they relate to a SaaS integration - Troubleshoot issues with API calls, data sync, webhooks, and integration points between Magento and the client's SaaS platform - Review custom modules, integration code, and configurations, and recommend improvements - Advise on how Magento's order, catalog, customer, and inventory systems interact with external systems - Advise on upgrades, security patches, and backend compatibility issues - Implement small backend fixes, API/module customizations, or integration enhancements as needed - Support performance and scalability concerns related to backend load (indexing, queues, caching, cron) - Communicate clearly with our engineering team and/or directly with the client on technical matters - Be available on relatively short notice for urgent, time-sensitive backend/integration issues (occasional) REQUIREMENTS - Magento Certified Developer (Adobe Commerce Developer or Magento 2 Certified Developer) required; Certified Expert, Backend Developer Expert, or Solution Specialist credentials a plus - Strong hands-on experience with Magento 2 / Adobe Commerce backend development (Open Source and/or Commerce edition) — this is not a frontend/theming role - Deep familiarity with Magento's REST and/or GraphQL APIs, service contracts, and module/plugin architecture - Experience integrating Magento with external platforms or SaaS products (custom APIs, message queues, webhooks, third-party systems) - Solid PHP, MySQL, and understanding of Magento's indexing, caching (Varnish/Redis), and cron/queue systems - Comfortable working independently with minimal oversight - Strong communication skills and responsiveness — this role depends on reliability more than raw hours - Prior experience in an ongoing support/consulting capacity (vs. one-off projects) preferred ENGAGEMENT DETAILS - Hours: ~10 hours/month on average, as-needed (may fluctuate month to month) - Duration: Ongoing, long-term relationship (not a fixed-term project) - Availability: Should be able to respond within a reasonable window when urgent issues arise - Rate: Please share your hourly rate and availability in your proposal HOW TO APPLY Please include: 1. Proof of Magento certification (certificate name/level) 2. A brief summary of your Magento 2 / Adobe Commerce backend and API experience 3. Any experience integrating Magento with external platforms, SaaS products, or third-party systems 4. Your typical response time/availability for ad-hoc requests 5. Your hourly rate We're looking to build a long-term working relationship with the right person, so reliability and clear communication matter as much as technical skill.
