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 Drupal Practice rulesets).
