• Cross-Browser Reliability:
  Ensure consistent behavior and performance across modern browsers (Chrome, Safari) and mobile environments through rigorous debugging and testing.
• API Integration & Data Management:
  Work with GraphQL APIs to efficiently fetch, manage, and synchronize data across the application.
• Code Quality & Collaboration:
  Use Git and distributed version control workflows to collaborate effectively with engineering teams and maintain clean, reviewable codebases.
• Testing Mindset:
  Contribute to a culture that values testing by writing and maintaining automated tests and ensuring application stability.
• Performance Optimization:
  Continuously identify and improve performance bottlenecks in browser-based applications.

What you bring:

• Strong Experience:
  5+ years of professional experience in software development, with a focus on frontend or full-stack web applications.
• Framework Expertise:
  Hands-on experience with modern JavaScript frameworks (React preferred; Vue or Angular acceptable).
• Core Web Technologies:
  Deep understanding of JavaScript (ES6+), modern CSS, and browser behavior.
• Version Control Proficiency:
  Experience working with Git and distributed version control systems in collaborative environments.
• Debugging Skills:
  Proven ability to identify, troubleshoot, and resolve issues across browsers and devices.
• Education:
  Bachelor’s degree in Computer Science or a related technical field, or equivalent practical experience.

Nice if you have:

• Performance Tuning:
  Experience optimizing JavaScript and browser-based applications for speed and efficiency.
• SPA Development:
  Experience building and maintaining single-page applications.
• Testing Tools:
  Familiarity with testing frameworks such as Jest or Cypress.
