• Work closely with Product, Design, Backend, QA, and other engineering teams.
• Identify and resolve complex performance, memory, concurrency, and stability issues.
• Drive code quality through code reviews, automated testing, CI/CD, and engineering best practices.
• Mentor and guide senior engineers and contribute to the overall technical growth of the team.
• Evaluate new iOS technologies and introduce them where they provide business or engineering value.
• Take ownership of critical technical initiatives and deliver solutions for complex engineering problems.

Requirements:

• Someone who is not just a strong iOS developer but can act as a technical authority for the mobile engineering team, driving architecture, solving complex problems, influencing engineering decisions, and building scalable iOS products.
