•          Ensure deliverables comply with Section 508, WCAG 2.1 AA, and District web standards.

•          Collaborate with client project managers, UX designers, content strategists, and agency stakeholders.

Required Technical Skills


HTML & Markup


•          Strong command of semantic HTML5: sectioning elements, headings hierarchy, lists, tables, and forms.


•          Solid grasp of web accessibility (WCAG 2.1 AA): ARIA roles and attributes, keyboard navigation, focus management, alt text, and accessible form labeling.


•          Familiarity with structured data and SEO markup: meta tags, Open Graph, Twitter cards, and Schema.org/JSON-LD.


•          Understanding of how Drupal renders markup through Twig, and the ability to produce clean, valid output via template overrides.


CSS & Styling


•          Deep working knowledge of modern CSS layout: Flexbox and CSS Grid, with sound judgment about when to use each.


•          Proficiency with responsive design: media queries, fluid typography, container queries, and mobile-first methodology.


•          Command of the cascade, specificity, and inheritance, with the ability to debug specificity conflicts rather than reaching for !important


•          Comfort with CSS custom properties (variables), modern color/spacing tokens, and maintainable theming patterns.


•          Awareness of cross-browser compatibility, vendor prefixing strategy, and progressive enhancement.


Nice to Have


◦           Strong SCSS/SASS skills: nesting, mixins, functions, partials, and a disciplined file architecture.


◦           A consistent CSS methodology such as BEM, and an understanding of how it maps onto Drupal's class conventions.


◦           Familiarity with CSS transitions, transforms, and animations, used with attention to performance and reduced-motion preferences.


JavaScript


•          Solid command of modern JavaScript (ES6+): arrow functions, destructuring, modules, promises, and async/await.


•          Strong DOM manipulation and event-handling skills, including event delegation and performance-conscious listeners.


•          Fluency with the Fetch API and asynchronous data handling, including JSON parsing and error handling.


•          Working knowledge of Drupal's JavaScript layer: Drupal.behaviors, once(), drupalSettings, and the AJAX framework


•          Understanding of how to attach and scope JS correctly through the Libraries API rather than inline scripts.


•          Familiarity with debugging via browser DevTools: breakpoints, the network panel, performance profiling, and the console.


Nice to Have


◦           Awareness of frontend performance: deferring/async loading, minimizing reflows, debouncing/throttling, and avoiding render-blocking scripts.


◦           Experience with a build/tooling pipeline (Webpack, Vite, or Gulp) and with linting/formatting (ESLint, Prettier, Stylelint).


◦           Exposure to a modern framework (React/Vue) is a plus, particularly for decoupled or partially decoupled Drupal frontends.


Drupal


Site Administration & Configuration Management


•          Fluency with the Drupal 9/10/11 admin UI: content types, fields, vocabularies, view modes, form/display modes, blocks, menus, URL aliases, and redirects.


•          Solid command of Configuration Management workflows: config export/import, config_split for environment-specific config, config_ignore for protected config.


•          Strong grasp of user access control: roles, permissions, content moderation workflows, and custom workflow states/transitions.


•          Demonstrated expertise with Views: complex queries, contextual filters, relationships, exposed filters/sorts, output rewriting, and REST exports.


•          Experience administering the Media Library, image styles, responsive image styles, and crop/focal-point strategies.


•          A clear mental model of what belongs in config vs. content vs. state vs. settings.php.


Theming & Frontend


•          Strong Twig skills: template suggestions, template preprocessing, and theme hook implementations.


•          Comfort with the Libraries API: defining JS/CSS, managing dependencies, and conditional loading.


•          Experience with modern base themes (Olivero/Stable9) and component-based theming.


•          Familiarity with Single Directory Components (SDC) for Drupal 10.3+.


•          Solid responsive design fundamentals, a disciplined CSS methodology (e.g., BEM), and SCSS/SASS proficiency.


Multi-Domain / Multi-Site (Nice to Have)


◦           Hands-on experience with the Domain Access module: domain entities, domain access fields on content/users/blocks, and current-domain negotiation.


◦           Practical command of the Domain Config module, including domain-specific config overrides and override precedence (settings.php > Domain Config UI > base config)


◦           A clear understanding of how config overrides cascade, and why programmatic overrides in settings.php will silently take precedence over UI changes


◦           Familiarity with cache contexts and invalidation in a multi-domain context.


◦           Experience with domain-aware menu, block, and pathauto strategies, and with cross-domain content sharing vs. domain-restricted content patterns


Security


•          Disciplined input sanitization and output escaping (Xss, Html, Url filters; Twig autoescaping).


•          A reflexive habit of using placeholders to prevent SQL injection and applying access checks on entity queries.


•          Working knowledge of file-upload security, CSRF tokens, and trusted host patterns.


•          Experience conducting permission audits and reviewing for privilege escalation.


DevOps, Deployment & Tooling


•          Understanding of Git workflows: feature branches, rebase vs. merge, conflict resolution, and hotfix patterns.


•          Strong Drush proficiency, including cache rebuilds, config import/export, user management.


•          Competence with Composer for project scaffolding, patching, and autoloader generation.


•          Experience with a local development environment, ideally Lando (DDEV/Docksal also welcome).


Nice to Have


◦           Familiarity with CI/CD pipelines (BLT, GitHub Actions, or Acquia Pipelines).


◦           Hands-on Acquia Cloud experience: environments, Cloud Hooks, code/database/files workflow, and Acquia CLI.


◦           Comfort with multi-database configuration and routing.


Integration & Standards (Nice to Have)


◦           Experience building and consuming REST APIs: JSON:API, the REST module, and custom REST resources.


◦           Experience with common third-party integrations: analytics and marketing automation.


Working Style & Collaboration


•          The ability to write technical documentation that a non-developer content editor can follow.


•          A methodical diagnostic approach — able to walk through debugging complex issues without guesswork.


•          Good code-review hygiene: readable commits, descriptive PRs, and openness to feedback.


•          Adherence to Drupal community coding standards (PHPCS with the Drupal and DrupalPractice rulesets).
