Senior Magento Developer

I'm working with a business that runs its ecommerce on an established Magento 2 platform and i'm looking for someone who can keep it running smoothly while it keeps evolving.

This isn't a ticket‑taking role. You'll be the client's go‑to Magento expert and sit between the internal team and their digital agency. You'll set the technical direction, sense‑check what the agency proposes and make sure what gets shipped is built properly.

It suits a contractor who likes ownership. You'll get a platform you can genuinely shape, a business that listens and a mix of BAU, integration work and new feature builds.

• Keep the live Magento 2 store stable, secure and performant day to day
• Triage and fix production issues, bugs and checkout or order flow problems
• Apply security patches and manage extension updates and compatibility
• Review the current version, PHP stack and hosting, and set out an upgrade path where needed
• Monitor performance across caching, indexing, Varnish, Redis and search

• Design and build integrations between Magento and third party systems such as ERP, PIM, OMS, payments, shipping and marketing platforms
• Work with REST and GraphQL APIs, webhooks, message queues and scheduled import or export jobs
• Make integrations resilient with clear logging, error handling and monitoring

• Act as the client's technical point of contact for their digital agency
• Give technical direction on architecture, approach and priorities
• Review agency estimates, specifications and pull requests and challenge where needed
• Translate business requirements into clear technical briefs
• Own release coordination and environments so nothing lands in production untested

• 5+ years commercial Magento 2 (Open Source or Adobe Commerce) development, ideally as a contractor
• Strong PHP 8.x and deep knowledge of Magento architecture: modules, plugins, observers, dependency injection, EAV and service contracts
• Proven integration delivery using Magento REST and GraphQL APIs with third party platforms
• Experience owning a live production store, including patching, upgrades and incident handling
• MySQL, Composer, Git and CI/CD pipelines
• Confidence working with and directing external agencies, including reviewing their code and estimates
• Clear communicator who can explain technical trade‑offs to non‑technical stakeholders

• Magento 2 version upgrades, particularly moving to 2.4.8 or 2.4.9
• Adobe Commerce Cloud, AWS or Hyvä theme experience
• Performance tuning with Varnish, Redis, Open Search and New Relic
• Adobe Commerce certification
• ERP or PIM integration experience (for example Sage, Net Suite, Dynamics or Akeneo)

• On site: 2 days a week in South Manchester for agency sessions, stakeholder time and planning. The rest is remote.
