Our ideal candidate will be a self-starter, capable of reviewing their own work thoroughly to check for issues and mistakes, and somebody who is proactive in locating and fixing existing bugs as well as proposing new features and ways to streamline the internal design of the system. The candidate will be expected to learn some Python and C coding (if not already proficient) for integration with the rest of the system; candidates with existing Python, C, and/or Cython experience are especially well-qualified in this regard. ### Job Responsibilities Locate, fix, and verify bugs in the FortiSwitchOS web-based GUI code. Brainstorm, propose, and implement new features for the GUI. Investigate bugs that may have associations or origins in other parts of the codebase (which is predominantly C code). Interface with other FortiSwitch team members to gain information or help diagnose and fix bugs that manifest in the GUI. Write and maintain significant amounts of i18n- and a11y- compliant HTML, JS and CSS, with careful attention to TypeScript rules, SCSS syntax, and general coding practices already reflected in the codebase. Compose functional specifications for new features and interface with QA, management, product, and/or other engineers to discuss and refine these specifications. Propose and proactively implement changes to the structure of the GUI codebase in order to improve maintainability and simplify the code structure and size. Assess and improve performance of the GUI system including both middleware/backend portions and frontend aspects and implement streamlined alternatives. ### Requirements At least 5 years of experience in front-end web development Familiarity or fluency with Typescript and SCSS. Fluency in HTML, CSS, and Javascript (ES6). Proficient in the use of AJAX and Promise methodologies. Familiar with front-end component-based frameworks such as Vue or React. Ability to learn new languages and technologies/frameworks quickly. Education in algorithmic complexity (independent of a particular language). Self-motivated with strong problem solving, diagnostic, and documentation skills. Ability to interface seamlessly with remote workers. ### Education Bachelor's or Master's degree in Computer Science or related area. Must be authorized to work in the U.S. without sponsorship. The US base salary range for this full-time position is $148,000-$180,000.
