What Is Front End Software Development?
Front end software development involves coding the user-facing aspects of a website or software program. Your responsibilities include using a variety of tools or IDEs (integrated development environments) to write or edit CSS (Cascading Style Sheets), HTML (Hypertext Markup Language), and Javascript code. As a front end software developer, your job is to use your skills to address the look, feel, and overall user experience of an application, more so than the speed, efficiency, or resilience of the backend of the application.

โข You have experience with automated testing practices and frameworks (e.g., Vitest, React Testing Library, Playwright or Cypress for E2E).
โข You have hands-on experience with state management patterns and libraries (e.g., Redux, Zustand, or React Query).
โข You have strong collaboration skills with product and design to deliver excellent UX.
โข You have strong command of Git in a professional engineering environment, including branch workflows, code review practices, and CI integration.
โข You have a Bachelorโs degree in CS/Engineering (or equivalent practical experience).
Preferred:
โข You have experience with complex data visualization (e.g., D3.js, Chart.js, or similar).
โข You have worked with graph databases and understand graph query patterns (e.g., Neo4j).
โข You have experience with real-time streaming data and production visualization of live systems.
โข You have experience in defense, security, or other mission-critical domains.
โข You have built UI experiences that surface AI/ML outputs in operational workflows.
โข You have experience with component library or design system development (e.g., Storybook).
