• Improve system reliability, performance, and security across the stack.
• Champion best practices in code quality, security, and testing.
• Lead code reviews and establish patterns that the rest of the team will follow.
• Mentor and support other engineers through code reviews, pairing, and technical guidance.

Requirements

• Experience collaborating with design using tools like Figma.

Qualifications
