About the role

We're looking for a WordPress Developer to take technical ownership of SEON's global website and help us build a faster, more scalable and reliable web platform. You'll be responsible for everything from developing custom Gutenberg blocks and maintaining our WordPress architecture to managing deployments, security, performance and integrations. Working closely with our Website Manager, Marketing, Design and SEO teams, you'll turn business requirements into robust, reusable solutions that enable us to launch campaigns, experiment and scale without unnecessary developer dependencies. This is a hands-on engineering role with significant ownership and autonomy. We're looking for someone who doesn't just deliver tickets, but proactively identifies opportunities to improve the platform, challenges technical decisions when necessary and takes pride in building a website that performs as well behind the scenes as it does for our visitors.

Location: US East Coast or Austin, TX

WHAT YOU'LL DO:

- Build and maintain custom Gutenberg blocks, patterns and page templates, extending the block editor so content can scale without developer involvement

- Own the custom SEON theme and plugin codebase: maintenance, refactoring, documentation and paying down technical debt

- Own the build pipeline and releases: Git workflow, staging, deployments to WP Engine, and rollback when something goes wrong

- Own site security: hardening, vulnerability monitoring, plugin and theme updates, and incident response

- Own site performance: Core Web Vitals, edge and object caching, and page speed

- Plan and deliver platform upgrades (WordPress core, PHP, MySQL) with full compatibility testing across the multisite network

- Make sure every change works across all three locales (EN, ES, PT-BR), including multilingual and hreflang behaviour

- Maintain the site's integrations, including forms and CRM, analytics and tag management, and cookie consent

- Implement technical SEO and accessibility with the SEO team: schema, crawlability and indexation, and WCAG 2.2 AA compliance

- Set and uphold engineering standards: code review, coding conventions, monitoring, backups and recovery testing

- Scope and estimate requests from marketing and design, and give technical direction to agencies or freelancers when they're used
