About The Position

We are seeking a highly skilled and experienced Senior Staff Software Engineer to join our dynamic team. In this role, you will be instrumental in designing, building, and maintaining robust application software with a strong emphasis on scalability and long-term maintainability. You will architect and implement full-stack solutions, seamlessly integrating server-side logic with frontend interfaces. A key part of your responsibility will be leading troubleshooting and root-cause analysis of backend systems, identifying and resolving complex issues efficiently. You will also design, build, and integrate RESTful APIs, and architect and manage relational and non-relational data storage solutions. Furthermore, you will conduct code reviews, establish engineering best practices, collaborate with cross-functional teams, mentor junior engineers, and contribute to architectural decision-making and technology roadmap planning.

Deep expertise in one or more PHP frameworks: Laravel, Yii, or Symfony.
Strong proficiency in HTML, CSS, and JavaScript, with hands-on React experience.
Proven ability to design and manage relational (MySQL, PostgreSQL) and non-relational (MongoDB, Redis) databases, including schema design and query optimization.
