Collaborate closely with product managers, designers, UX professionals, and engineering teams.
Troubleshoot and resolve issues across the application stack.
Identify opportunities to improve application functionality, performance, and maintainability.
Write clean, maintainable, and well-tested code.
Participate in code reviews, technical discussions, testing, and Agile development practices.
Contribute to improving development processes, application quality, and engineering standards.

Required Qualifications

Strong professional experience in full-stack software development.
Strong hands-on experience with React.
Strong proficiency in JavaScript and/or TypeScript.
Experience developing and integrating APIs and backend services.
Solid understanding of modern web application architecture.
Experience working across both front-end and backend technologies.
Experience building, debugging, and maintaining production applications.
Strong problem-solving and troubleshooting skills.
Ability to collaborate effectively with product, design, UX, and engineering teams.
Strong communication and teamwork skills.

Preferred Qualifications

Professional experience with Ruby on Rails.
Experience working with enterprise-scale applications.
Experience with databases and backend data models.
Experience with automated testing across the application stack.
Familiarity with CI/CD and modern software development practices.
Experience with design systems or reusable front-end component libraries.
Familiarity with accessibility, performance optimization, and responsive web development.
Experience working in an Agile/Scrum environment.

What You'll Bring

You are a senior full-stack engineer with a strong front-end foundation and proven React expertise, combined with the ability to work effectively across the application stack.
