About the role

We’re seeking a PHP Architect (Magento 2 / Adobe Commerce, OXID, Shopware) to lead the design and evolution of our e-commerce platforms. You’ll set coding standards, perform deep code reviews on complex flows (catalog, checkout, payments, promotions), and mentor teams in building scalable, secure, high‑performing systems. Strong OOP/SOLID skills are essential; hands‑on e-commerce experience is required.

Key responsibilities

• Architecture & design: Own application and domain architecture for PHP services (modular monolith or microservices). Apply OOP/SOLID, design patterns, and clean architecture/DDD where appropriate.
• Code governance: Establish PSR standards (PSR‑4/12), review complex PRs, enforce quality gates, and guide refactors to reduce tech debt.
• E‑commerce domain leadership: Model domains like catalog, pricing/promo, carts, checkout, orders, payments, tax, shipping, inventory, and returns.
• Hands on coding: This role involves hands on development work. Do not apply if you are not interested in doing that.
• Performance & scalability: Profile and tune (OPcache, PHP‑FPM), optimize queries and caching (Redis), implement queues (RabbitMQ/SQS) and async jobs.
• API & integrations: Design REST/GraphQL APIs; integrate with payment gateways (Stripe/Adyen/Braintree/PayPal), tax (Avalara), shipping/fulfillment, search (Elasticsearch/OpenSearch), and ERP/CRM.
• Security & compliance: Embed OWASP best practices, protect PII, and support PCI‑DSS‑aware design across payment flows.
• Testing & reliability: Champion automated tests (PHPUnit/Pest), contract/integration tests, CI/CD pipelines, and observability (logs/metrics/traces).
• Mentorship & collaboration: Coach engineers, run design reviews, and work with product/ops to deliver resilient releases.

Required qualifications

• Experience: 10+ years professional PHP; 3+ years in an architect/lead role shipping large apps.
• Platform: Magento 2 / Adobe Commerce, OXID, Shopware
• OOP mastery: Deep SOLID, common patterns (Strategy, Factory, Adapter, CQRS), and pragmatic refactoring.
• Frameworks: Expert in Laravel and/or Symfony; strong Composer/autoloading knowledge.
• Data layer: MySQL/PostgreSQL schema design, query tuning, migrations; caching with Redis; hands‑on with search engines (Elasticsearch/OpenSearch).
• E‑commerce exposure: Built or scaled complex flows (promotions/discount engines, multi‑store, multi‑currency, tax, inventory, OMS).
• Tooling: PHPUnit/Pest, static analysis (PHPStan/Psalm), linters, Git PR workflows, CI (GitHub Actions/GitLab/Jenkins).
• APIs & async: REST/GraphQL design, webhooks, queues/workers (RabbitMQ/SQS), rate‑limiting and idempotency patterns.
• Soft skills: Clear communication, architectural documentation, and ability to lead cross‑functional design discussions.

Nice to have

• Platforms: Magento 2 / Adobe Commerce, OXID, Shopware, Sylius, OroCommerce, or headless builds (e.g., Laravel/Symfony + headless storefronts like Next.js).
• Payments & tax: Deep experience with Stripe/Adyen/Braintree/PayPal and tax services (Avalara/Vertex).
• Front‑end integration: Understanding of headless/SPA storefronts, GraphQL gateways, and edge caching/CDNs.
• Cloud & DevOps: Basic AWS/GCP for PHP runtimes (FPM/Nginx), containers or serverless for specific workloads, IaC familiarity.
• Event‑driven: Kafka/EventBridge patterns for order events and downstream sync.

• Competitive compensation and benefits
• Flexible work options and supportive, collaborative culture
• Budget for tools, and certifications
• Opportunity to shape the architecture of high‑traffic e‑commerce systems
