Software Engineer IV - Frontend

Mighty Acorn Digital

4d • Remote

About The Position

At Mighty Acorn, Software Engineer IV is a senior-level role for engineers who bring deep expertise and the judgment to drive complex work forward with minimal oversight. For this role, that expertise is frontend development — specifically the craft of building accessible, well-structured web experiences that help government teams build consistently and confidently.
You'll be embedded on a team building and maintaining a design system and its documentation site for a government client. A design system is only as valuable as its documentation: if engineers and designers can't understand how to use a component correctly, the system fails. Your work will directly shape how the client's teams learn, adopt, and contribute to a growing library of components and patterns — making it easier for everyone across the agency to ship consistent, accessible digital services.
This is a fully remote position. Candidates must be based in and work from the contiguous United States, with at least a 5-hour overlap with 9am–5pm ET, Monday through Friday.

Requirements

• 7+ years of professional software engineering experience with a strong frontend focus.
• Deep proficiency in HTML, CSS, JavaScript, and React — able to write clean, semantic, accessible markup and understand how the web platform works beneath any framework.
• Hands-on experience working with or implementing component-based design systems.
• Experience with Astro or a comparable static site generator (Next.js, Eleventy, etc.).
• Demonstrated knowledge of web accessibility standards (WCAG), including semantic HTML, ARIA usage, keyboard navigation, and screen reader behavior.
• Experience implementing USWDS.
• Strong written communication skills — able to produce clear, accurate documentation usable by both developers and designers.
• Comfort collaborating across disciplines (design, engineering, product) and translating between them.
• Ability to manage your own work in a distributed team with evolving requirements.
• A Bachelor's degree (or equivalent experience) is contractually required for this role.
• An ability to work efficiently, sometimes under tight deadlines.
• A preference for transparency and an ability to be direct and transparent in your own communication.
• An ability to adapt quickly and cope with temporarily ambiguous situations as requirements change.
• This role requires work be performed from within the contiguous United States.
• Candidates must either hold active US citizenship or a green card, and should possess work authorization that does not require any present or future visa sponsorship by Mighty Acorn Digital.
• Candidates selected for the role must pass a criminal background check prior to their start date.
• Candidates must have a fast (>100Mbps) and reliable internet connection and have a dedicated workspace with background noise at an appropriate level for audio calls.

Nice To Haves

• Familiarity with design tokens, theming systems, or multi-brand design system architectures.
• Experience testing for accessibility using both manual testing and automated tooling (e.g., axe, Lighthouse, NVDA/VoiceOver).
• Familiarity with reviewing component and token libraries in Figma dev mode.
• Experience testing components using tools such as Chromatic, Playwright, Vitest, Jest, or Cypress.
• Experience working with AWS, particularly AWS Amplify.
• Experience working in or alongside government agencies or federal digital services programs.

Responsibilities

• Building and maintaining a design system documentation site built with Astro, including component pages, usage guidelines, and code examples.
• Translating design specifications and component updates into clear, accurate documentation that developers and designers can rely on.
• Collaborating with designers and engineers to keep documentation in sync as components and patterns evolve.
• Reviewing and contributing to the design system's component library with a focus on accessibility compliance and semantic markup.
• Participating in agile ceremonies — planning, standup, and retrospectives — and actively contributing to team-level problem solving.
• Managing your own priorities in a distributed team, raising blockers early and communicating status clearly.
