• Serve as the front-end technical authority in project planning, sprint execution, and architectural decision-making.
• Work closely with DevOps and cloud engineering teams to ensure seamless deployment pipelines within the AWS environment.
• Provide input on technical roadmap planning, technology selection, and long-term platform scalability.

Qualifications

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
• 8+ years of front-end development experience, with at least 2+ years in a senior or staff-level technical leadership role.
• Expert-level proficiency in React, TypeScript, and modern JavaScript (ES6+).
• Strong understanding of API design and integration, preferably with NestJS or similar Node.js frameworks.
