Senior Lead for WordPress Business Platform

Yes. I’d advertise this as a senior delivery-team / technical lead opportunity, not a cheap generic WordPress job. You want applicants who can demonstrate they have already delivered this type of platform and understand the entire lifecycle from discovery through launch and support.

Title
Senior WordPress Development Team / Technical Lead – Complex Public-Sector Business Support Platform
Job description
We are seeking a highly experienced Senior WordPress Developer / Web Development Team to work with our UK company on the design and delivery of a substantial business-support website.
This is not a basic WordPress or template website project. We are looking for professionals who can take responsibility for the technical delivery of a high-quality, production-ready platform from discovery and technical architecture through development, integrations, testing, deployment and ongoing support.
The required solution includes:
- Custom, professionally engineered WordPress website
- Responsive UX/UI across desktop, tablet and mobile
- Flexible, reusable page templates and content modules that non-technical staff can manage
- HubSpot CRM integration
- Event management, including event registration/attendance integration
- Advanced site-wide search
- Categories, tags, filters, sorting and relevance
- User accounts and personalisation functionality
- Architecture capable of supporting future AI-powered search, recommendations and personalisation
- API-friendly/scalable architecture
- WCAG 2.2 AA accessibility
- Excellent website performance and Core Web Vitals
- Strong cybersecurity and secure development practices
- Appropriate user authentication and permissions
- Backup, disaster recovery and resilience
- QA, browser/device testing and accessibility testing
- Deployment to production
- Technical documentation and handover
- Ongoing maintenance, updates, monitoring and technical support
We want applicants who understand that this is an end-to-end digital platform project, not simply a website build.
Who we are looking for
We particularly want to hear from Senior/Lead WordPress Developers, Technical Architects or established development teams who have previously delivered complex websites or digital platforms.
Strong applicants should have demonstrable experience in several of the following:
WordPress development • custom themes/plugins • PHP • JavaScript • REST APIs • HubSpot integrations • CRM integrations • advanced search • user accounts • accessibility/WCAG • cybersecurity • performance optimisation • cloud/managed hosting • automated backups • Git/version control • staging/production environments • QA/testing.
Experience delivering websites for government, local authorities, public-sector organisations, business-support organisations, universities, membership organisations or other large organisations would be particularly valuable.
VERY IMPORTANT – your application

Please include:
1. Your name, location and role.
2. Years of professional web-development experience.
3. Whether you are an individual developer or an established team/company.

All experience must be genuine and verifiable. Please clearly distinguish between projects completed by your company/team and projects you personally worked on while employed or subcontracted elsewhere.
Data security
The successful team will be expected to work within strict UK data-protection and information-security requirements.
Development may involve international/remote team members, but access to live personal data will be restricted and developers may be required to work with synthetic/test data unless appropriate authorisation and safeguards are in place.
Successful applicants will also be required to agree to appropriate:
Confidentiality / NDA • intellectual-property assignment • data-protection requirements • secure development requirements • availability and delivery commitments.
Project approach
We expect the successful technical team to contribute across:
Discovery → requirements → architecture → UX/UI → development → integrations → testing → accessibility → security → deployment → handover → maintenance/support.
We already have project/business management capability and previous digital-project experience. We are looking to add exceptional technical specialists with a proven track record to the delivery team.
