WordPress / WooCommerce Developer (High-Load E-commerce)

We are looking for a Senior WordPress / WooCommerce Developer to take technical ownership of a high-load e-commerce platform serving the US & Canada market.
The platform processes thousands of time-sensitive orders daily, with extreme peaks during seasonal events.

Reliability, performance, and clear communication are critical.

Responsibilities

• Develop and maintain a high-traffic WordPress / WooCommerce platform (custom themes, plugins, core features — not just configuration).
• Design and evolve platform architecture with a focus on performance, scalability, and maintainability.
• Ensure system stability during peak loads (holidays, campaigns) via performance tuning, load testing, and controlled releases.
• Integrate and maintain third-party services: payment gateways, shipping providers, CRM/ERP, marketing tools.
• Optimize MySQL queries and database structure for large product and order volumes.
• Collaborate closely with Product, Marketing, Operations, and QA to align technical solutions with business needs.
• Break down work into clear tasks, provide realistic estimates, and proactively flag risks and dependencies.
• Participate in sprint planning, backlog grooming, and retrospectives.

• Maintain engineering standards: Git workflow, code reviews, staging environments, CI/CD, monitoring, and rollback strategies.

   

Requirements

• 5+ years of professional PHP experience, with strong hands-on work in WordPress & WooCommerce.
• Deep understanding of WordPress core, hooks, plugin and theme architecture.
• Strong WooCommerce expertise: checkout, orders, coupons, catalogs, high-volume data.
• Solid MySQL skills: query optimization, indexing, profiling, understanding WooCommerce performance bottlenecks.
• Strong OOP skills; experience with MVC and modular PHP architecture.
• Proven experience with high-load systems, including:
  • Caching (object/page cache, opcode cache, Redis/Memcached)
  • Scaling WordPress/WooCommerce across multiple servers or containers
• Confident Git usage (feature branches, PRs, code reviews).
• Familiarity with production environments: logs, error tracking, performance monitoring, alerts.

• Strong English communication skills (spoken & written).

   

How we work

• Small cross-functional team (Product, Engineering, QA, Operations).
• Separate staging and production environments with mandatory code reviews.
• Controlled releases during peak periods, with rollback and post-incident analysis.

• Focus on long-term platform health, not short-term “ticket delivery”.

   

Mindset we’re looking for

• Ownership: you treat the platform as your product.
• Pragmatism: you understand trade-offs and constraints.
• Clear communication: you can explain technical decisions to non-technical stakeholders.
• Estimation discipline: honest timelines, early risk communication.

• Calm under pressure: systematic incident handling, root-cause focus.
