WordPress developers build, customize, and maintain websites on the world's most widely used content management system, handling everything from theme design to e-commerce integration. Whether you need a portfolio site, a membership platform, or a high-traffic online store, the right developer turns a generic template into a tailored digital experience that scales with your business.
What does a WordPress developer do?
WordPress developers design, build, and maintain websites using the WordPress platform, combining front-end design skills with back-end programming to create sites that look polished and perform reliably. They work with PHP, HTML, CSS, and JavaScript to extend WordPress beyond its default capabilities, turning it into a fully customized content management system tailored to your business goals.
WordPress developers generally address these areas:
- Custom theme and plug-in development. Building bespoke themes from scratch or modifying existing ones, and creating plug-ins that add specific functionality your site needs
- Website architecture and performance. Structuring page hierarchies, optimizing load times, configuring caching, and ensuring the site handles traffic spikes smoothly
- Security and maintenance. Hardening WordPress installations against vulnerabilities, managing updates for core software and plug-ins, and running regular backups
- E-commerce and API integrations. Setting up WooCommerce stores, connecting payment gateways, and integrating third-party services like CRMs, email platforms, and analytics tools
- SEO and accessibility. Implementing technical SEO best practices, structuring content for search visibility, and ensuring the site meets accessibility standards
How to hire a WordPress developer on Upwork
Upwork gives you access to thousands of WordPress developers across every specialization — from theme customization to complex plug-in architecture. Follow these four steps to find, evaluate, and start working with the right developer for your project.
Step 1: Post a job
Start by writing a clear job post that outlines your WordPress project requirements, Specify whether you need theme development, plug-in customization, migration, or ongoing maintenance.
- Include the PHP version your hosting environment runs, any must-have plug-ins or WooCommerce needs, and whether you need a developer comfortable with block editors or classic themes
- List required technical skills (PHP, JavaScript, MySQL, REST API experience)
- Include details about your hosting setup, existing plug-ins, and any third-party integrations
- Specify whether you need a custom theme, WooCommerce store, membership site, or headless WordPress implementation
- Indicate any requirements for SEO, page speed optimization, or accessibility compliance
- Clarify whether content migration, plug-in selection, or ongoing support is part of the project
- Share your expected budget and timeline
- Reference this WordPress developer job description page for additional guidance on structuring your post
Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to speed things up. Describe your WordPress project in a few sentences, and Uma will draft a tailored job post that you can review and customize..
Step 2: Evaluate candidates
When proposals start coming in, focus on WordPress-specific signals. A developer who can show before-and-after page speed results or a live portfolio of custom WordPress builds gives you much more confidence than a generic resume.
- Review portfolios for custom WordPress themes, WooCommerce stores, and plug-in work
- Check for theme repositories, plug-in contributions, and measurable performance improvements on past projects
- Look for a focus on your specific needs (e.g., multisite setups, multilingual support, or headless WordPress) and experience optimizing Core Web Vitals, page speed, and site performance
- Review examples of custom theme development, plug-in customization, or WooCommerce implementations
- Check for experience integrating payment gateways, CRMs, marketing tools, or other third-party services
- Check Job Success Score and client feedback on similar WordPress projects
- Consider talent badges like Top Rated, Top Rated Plus, and Expert-Vetted for high-stakes projects
Uma can also help by conducting instant video interviews and providing shortlists of WordPress developers with side-by-side comparisons, so you can quickly identify your strongest candidates.
Step 3: Interview top choices
Use interviews to dig into how each candidate handles real WordPress challenges, such as plug-in conflicts, security hardening, performance bottlenecks, and version upgrades. Their approach to troubleshooting can reveal more than their resume.
- Ask how they handle plug-in conflicts and what their process is for debugging issues on a live site
- Discuss their approach to responsive design and cross-browser testing
- Explore how they manage WordPress security (firewalls, malware scanning, user permissions)
- Inquire about their workflow for staging, version control, and deployment
- Ask how they approach WordPress performance optimization and caching strategies
- Discuss experience with WooCommerce, custom post types, and Gutenberg block development
- Explore how they handle backups, updates, and long-term site maintenance
- For additional question ideas, visit the WordPress developer interview questions page
You can schedule and conduct interviews directly within Upwork Messages, which provides an immediate transcript and summary.
Step 4: Agree on scope and begin work
Before work starts, define exactly what you'll receive in an agreed contract. Clear scope prevents surprises and keeps your WordPress project on track.
- Choose between a fixed-price contract for defined deliverables (like a completed theme) or hourly for ongoing work (like maintenance)
- Confirm theme files, plug-in documentation, staging site access, and a timeline for each milestone
- Define responsibilities for development, testing, deployment, and post-launch support
- Clarify ownership of theme files, custom plug-ins, documentation, and site assets
- Establish approval checkpoints for staging reviews, testing, and final launch readiness
- Set milestones tied to specific outputs: wireframes, staging site review, final launch
- Agree on a staging environment for testing before changes go live
Use Messaging and the contract workroom for day-to-day communication, with identity verification, Hourly Payment Protection, and project funds keeping the engagement secure.
