• Contribute to technical and architectural decisions, helping continuously modernize and improve the product.
• Take ownership throughout the product lifecycle, from design and implementation to testing, troubleshooting, and resolving escalated customer issues.
• Promote strong engineering practices around code quality, security, performance, reliability, and maintainability.

What you'll need:

• Proven record (5+ years) delivering multiple complex software development projects or products.
• Strong hands-on experience with TypeScript and modern React.
• Strong understanding of web application architecture, including performance, security, reliability, quality, and maintainability.
• Good understanding of modern cloud architectures, with practical experience building and operating applications in AWS, GCP, or similar cloud environments.
• Experience designing and integrating REST APIs and external services, including authentication, error handling, and rate limiting.
• Strong engineering practices around automated testing, code reviews, and CI/CD.
• Ability to analyze and decompose complex problems into clear, maintainable, and realistic solutions.
• Willingness to work across frontend and backend technologies and learn new technologies when needed.
