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).
