Senior Wordpress developer

At Speed & Function, we’re hiring a Senior WordPress Developer ready to take technical ownership within a broader ecosystem – not just execute tasks. This role sits within our Solutions Department and involves working across a network of complex, content-rich platforms.
 

You’ll engage with long-term projects in healthcare, education, and self-development – areas where stability, scalability, and user impact go hand in hand. We’re looking for someone who brings architectural thinking, understands trade-offs, and is motivated by building systems that serve real people at scale.
 

If you’re looking to grow beyond feature delivery and contribute to a broader technical and human context, we’d like to meet you.
 

Key Responsibilities

• Build, extend, and maintain complex WordPress platforms – including custom themes, plugins, and third-party integrations – with an eye on scalability and long-term value.
• Lead implementation of new features and platform improvements, balancing short-term impact with architectural integrity.
• Refactor and stabilize legacy codebases, improving reliability, security, and maintainability over time.
• Collaborate with the CMS Tech Lead, PMs, and fellow engineers to clarify intent, estimate effort, and challenge assumptions where needed.
• Coordinate with DevOps on deployment pipelines, environment management, and incident resolution to ensure operational continuity.
• Shape content models, migrations, tagging, and analytics logic in alignment with product and data strategies.
• Contribute to structured migrations from legacy systems into modern WordPress architectures with minimal disruption.
• Review code constructively, offer insights, and help elevate engineering practices within the department.
• Join client-facing conversations as a technical partner — explaining trade-offs, guiding decisions, and contributing to shared outcomes.
   

Required Qualifications

• WordPress: 6+ months on a 3–5 dev WP project; strong core architecture knowledge; custom themes and plugins from scratch; ACF, custom post types & taxonomies; advanced work with page builders (Gutenberg / Elementor / WPBakery / etc.); solid grasp of template hierarchy, hooks & filters; multisite a plus.
• Front-End: Strong HTML5, CSS3/SASS, JavaScript (ES6+); component-based approach; responsive layouts; cross-browser support; accessibility & performance optimisation a plus.
• Integrations & APIs: Third-party and REST APIs; HubSpot (Marketing Hub / Sales Hub / Forms API); search plugins (e.g. SearchWP); webhooks & data sync; GTM a plus.
• Auth & Security: Custom authentication flows, 2FA, role/permission management; WordPress security best practices.
• SEO & Performance: Advanced SEO (schema/structured data, Open Graph, XML sitemaps); understanding of Core Web Vitals; experience with SEO plugins; AI/LLM search optimisation a plus.
• Data, Scale & Performance: DB migrations and content import/export; caching (object/page/CDN); experience with large sites (~2,000+ pages, ~1,500+ users); performance monitoring/troubleshooting.
• Workflow: Git, local envs (Docker/Local/etc.), staging→production deployments; documentation and CI/CD concepts.
• Nice to have: Drupal, Composer, multilingual (WPML/Polylang), consent platforms (e.g. OneTrust), work with design systems / Storybook.

Other:

• English at B2 level or higher, including the ability to participate in meetings with international clients.
• A self-directed working style: you keep your promises, you communicate early when plans change and you see yourself as responsible for outcomes, not only for lines of code.
   

What We Offer

• Work that has context and meaning, not just a queue of anonymous tasks.
• A chance to become a primary expert in the WordPress direction inside an established CMS practice with 100+ active sites.
• A culture that treats growth as a shared responsibility: we are interested in how you evolve as a person and as an engineer, not only in what you deliver this sprint.
• Access to coaching, internal development programs, therapy reimbursement and English lessons.
• Flexible hours and a remote-first setup, with a core window in the afternoon and evening to keep overlap with US clients.
• A high-trust environment where initiative is noticed and appreciated, and where you are invited to shape how we work, not only to follow existing routines.
