Role: Web Developer Master Location: Washington, DC Client: DC Government Job Description: Scope of Work • Design, develop, and maintain Drupal-based websites supporting DC.gov and District agency platforms. • Build and customize Drupal modules, themes, content types, taxonomies, and views per agency requirements. • Perform Drupal core and contributed module updates, security patches, and version migrations (e.g., Drupal 7 to Drupal 10/11). • Integrate Drupal sites with enterprise systems, APIs, and third-party services. • Ensure deliverables comply with Section 508, WCAG 2.1 AA, and District web standards. • Apply web security best practices consistent with OCTO and federal cybersecurity guidelines. • Collaborate with OCTO project managers, UX designers, content strategists, and agency stakeholders. • Produce technical documentation, code comments, and operational runbooks. • Provide Tier 3 production support and participate in deployment activities, including occasional after-hours work. 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 fo
