Job Summary

Aretum is seeking a skilled Frontend Web Developer with a strong focus on digital accessibility to join our team supporting a large-scale federal technology modernization program. In this role, you will build and maintain Angular web applications and UI components while ensuring every interface you deliver is accessible to people with disabilities. You will implement designs from Figma, integrate Design System components, write frontend tests, and take ownership of accessibility compliance in your code, including proper ARIA attributes, semantic HTML, keyboard navigation, focus management, and color contrast. You will work as an embedded member of an Agile scrum team, collaborating closely with UX designers, backend developers, accessibility specialists, and federal product owners within a SAFe framework.

Due to the nature of our work as a federal consulting organization, employees may be expected to handle Controlled Unclassified Information (CUI) and must adhere to applicable safeguarding and compliance requirements.

Responsibilities

• Develop Angular components and UI features against sprint commitments, implementing designs from Figma using approved Design System components, tokens, and patterns
• Implement frontend accessibility standards in all UI code: proper ARIA attributes, semantic HTML, keyboard navigation, focus management, and color contrast compliance per WCAG 2.1 AA and Section 508
• Ensure all new UI code passes automated accessibility checks (aXe, pa11y) in the CI pipeline before merge, with zero critical or major findings
• Contribute to accessibility remediation of legacy UI code, resolving existing accessibility defects and preventing new ones from being introduced
• Write frontend tests (component tests, service tests, integration tests) achieving at least 90% branch coverage on all new and modified code
• Complete code reviews within 1 business day with substantive feedback focused on code quality, accessibility implementation, and Design System adherence
• Collaborate with UX designers on accessible design patterns, with backend developers on API contracts and data integration, and with accessibility specialists to resolve evaluation findings efficiently
• Contribute to the Design System through the governance process: propose new components or patterns, ensure contributions meet WCAG 2.1 AA, and document usage in Figma and Confluence
• Build responsive, cross-browser interfaces that work across supported browsers and devices
• Participate fully in Agile ceremonies within a SAFe framework: Sprint Planning, Daily Standup, Sprint Review, Retrospective, and Backlog Refinement
• Support production triage when assigned, ensuring all fixes follow the standard code review and CI/CD pipeline process
• Maintain clean, well-documented TypeScript and Angular code that meets coding standards and passes SonarQube quality gates

Requirements

• 3 years of applicable experience in frontend web development
• Bachelor's degree in Computer Science, Information Technology, or a related field (or 3 years of additional experience)
• Proficiency in Angular (version 12+), TypeScript, HTML5, and CSS3, with hands-on experience building component-based single-page applications
• Strong working knowledge of WCAG 2.1 AA accessibility standards and Section 508 compliance, with demonstrated experience implementing accessible UI patterns including ARIA attributes, semantic HTML, keyboard navigation, and focus management
• Experience with automated accessibility testing tools such as aXe, pa11y, or WAVE, integrated into development or CI workflows
• Experience implementing designs from Figma or similar design tools, translating visual specifications and accessibility annotations into production code
• Experience working with a shared Design System or component library, consuming and contributing reusable UI components with documented usage patterns
• Experience with CI/CD pipelines (GitLab CI preferred) and understanding of how frontend builds, tests, and accessibility scans integrate into the deployment workflow
• Experience writing frontend unit and integration tests using frameworks such as Jasmine, Karma, or Jest
• Familiarity with code quality tools such as SonarQube, including understanding of branch coverage requirements and quality gate enforcement
• Excellent communication skills with the ability to provide clear status updates, collaborate with cross-functional partners on accessibility remediation, and document technical decisions

Preferred Qualifications 

• Experience with federal government contracts, including compliance with FAR regulations, ATO processes, and working on mission-critical or regulatory systems
• DHS Trusted Tester certification, or equivalent accessibility credential
• Experience with manual screen reader testing using JAWS or NVDA to validate accessibility beyond automated scanning
• Proficiency with Agile project management tools (Jira, Confluence) and experience working in Scrum or SAFe environments with 2 to 3 week sprint cycles
• Experience with Bootstrap or similar CSS frameworks used alongside a custom Design System
• Experience consuming RESTful APIs and integrating frontend applications with microservices-based backends
• Familiarity with responsive design principles and cross-browser testing across modern browsers and devices
• Experience with Playwright or Cypress for end-to-end frontend testing
• Background in building applications that integrate with federal identity providers or federal payment systems
