Full Stack Developer (Drupal 10 and WordPress)

Potomac Haven is seeking an experienced Full Stack Web Developer to lead the development of a new stand-alone campaign website for the Missouri Department of Mental Health’s (DMH) Problem Gambling Prevention initiative. In this role, you will drive the website’s full development lifecycle – from architecture and UX/UI design to front-end/back-end development, testing, deployment, hosting, and ongoing maintenance. You will ensure the site meets high standards of functionality, user experience, performance, security, and accessibility. This project is a centerpiece of Missouri’s public health campaign against problem gambling, and the new site will provide educational resources and tools to help curb gambling addiction. 

Key Responsibilities: 

• End-to-End Web Development: Design and implement a modern, user-friendly website on a contemporary CMS (e.g. WordPress or Drupal) to be deployed on a secure cloud platform. You will create a responsive UI aligned with campaign branding and build all required features – from content pages and navigation to interactive elements – ensuring a seamless user experience. Both front-end (HTML5, CSS3, JavaScript, frameworks like Bootstrap/jQuery) and back-end development (PHP-based CMS customization, database integration) are central to this role. 
• Architecture & Hosting: Define the site’s technical architecture and set up robust hosting in a scalable AWS cloud environment. Configure web servers (such as Nginx) and caching systems (e.g. Varnish or other CDN caching) to optimize performance and reliability. Ensure strong security practices, including SSL/TLS encryption, HSTS protocols, and use of web application firewalls (the Missouri DMH’s current environment employs Imperva for web security). 
• Accessibility & Compliance: Ensure full ADA/WCAG 2.1 AA compliance across the website’s design and code. Conduct accessibility audits (using tools like Siteimprove or similar), implement responsive design and semantic HTML, provide alt text for images, and remediate any issues so that the site is fully accessible to all users. Adhere to Section?508 standards and other relevant state web accessibility/privacy requirements, delivering a site that meets public-sector compliance benchmarks. 
• Analytics & Data Integration: Set up comprehensive analytics from day one to measure campaign effectiveness. Implement Google Analytics 4 (GA4) and Google Tag Manager, including defining custom events and conversion goals (e.g., tracking clicks on “Get Help” resources, downloads, video plays). Coordinate with campaign strategists to use UTM parameters for all media links, enabling detailed source tracking. 
• Dashboard & Reporting: Develop a custom performance dashboard (e.g., using Google Looker Studio/Data Studio) to visualize key metrics such as site traffic, user engagement, and conversions. Maintain and update the dashboard regularly, and automate reports (weekly summaries, monthly analysis) to provide stakeholders with clear insights into the campaign’s impact. You will present data in a meaningful way and possibly integrate additional data sources (like social media or ad analytics) over time to enrich the reporting. 
• Collaboration & Project Management: Work remotely as part of a cross-functional team, participating in weekly virtual meetings with DMH and partner agencies. Collaborate closely with content strategists and designers to integrate provided campaign content and branding into the site. Communicate technical concepts and progress updates clearly to non-technical stakeholders, gather feedback, and adjust deliverables accordingly. Manage development timelines and tasks effectively to meet an aggressive launch schedule, proactively identifying and mitigating any risks or blockers. 

Required Qualifications: 

• Experience: Bachelor's degree in Computer Science, Information Systems, or a related field (or equivalent experience). 5+ years of professional full-stack web development experience, including building and launching dynamic websites or web applications end-to-end. Demonstrated success in similar projects – for example, developing public-facing sites for government, healthcare, or public health initiatives – is highly desirable. 
• Technical Proficiency: Strong coding skills in front-end technologies (HTML5, CSS3, JavaScript) with experience in frameworks/libraries like Bootstrap and jQuery for responsive, user-friendly interfaces. Expertise in back-end development using PHP and hands-on experience with content management systems – especially WordPress and/or Drupal 10 – is required. Familiarity with Drupal multisite environments or enterprise hosting (e.g., Drupal on Acquia/AWS) is a plus. Competence in configuring and managing cloud hosting (AWS or similar cloud platforms), including setting up Linux/Nginx web servers, working with relational databases (MySQL), and implementing caching/CDN solutions (such as Varnish) to ensure high performance1. Knowledge of web security best practices (SSL, secure authentication, Imperva WAF or similar security tools) is expected. 
• Analytics & Data Skills: Proven ability to implement and configure web analytics. Must have experience setting up Google Analytics 4 and Google Tag Manager for websites, including defining events, tracking conversions, and analyzing user behavior data. Experience building interactive data dashboards or reports (using tools like Google Looker Studio, Tableau, or similar) to communicate web performance metrics is required. Familiarity with SEO and quality assurance tools (e.g., Siteimprove) for monitoring site health and compliance is beneficial. 
• Accessibility & Compliance: Deep understanding of ADA/WCAG 2.1 AA accessibility guidelines and proven success in implementing them on web projects. Experience conducting accessibility audits and remediation (ensuring proper semantic HTML, ARIA roles, alt text, keyboard navigation, etc.) to achieve full compliance. Awareness of Section 508 requirements and general data privacy/security standards for government or healthcare websites. 
• Soft Skills: Excellent communication, teamwork, and organizational skills. Ability to thrive in a remote work environment, coordinating effectively via video calls, email, and project management tools. Comfortable leading discussions in client/stakeholder meetings (e.g., weekly status updates) and translating client needs into technical action items. Strong problem-solving mindset, attention to detail, and the adaptability to meet tight deadlines in a fast-paced campaign setting. 

Preferred Qualifications (Bonus):  Relevant professional certifications are a plus, including Google Analytics (GA4) certification or Google Analytics Individual Qualification (demonstrating advanced GA4/Tag Manager skills), Accessibility certifications (such as IAAP’s Certified Professional in Accessibility Core Competencies or related credentials), cloud platform certifications (e.g., AWS Certified Solutions Architect or Developer), or CMS certifications (e.g., Acquia Certified Drupal Developer). These certifications will be considered favorably as evidence of your expertise and commitment to best practices in web development.
