• Obsessed with Quality: You are passionate about code quality, maintainability, observability, and best practices across the platform

• Proactive & Collaborative: You have a proactive approach to problem-solving and can effectively communicate technical concepts to both technical and non-technical team members

• Balancing Speed & Quality: You are comfortable working in a fast-paced, startup-like environment, balancing speed and quality while demonstrating a strong desire for ownership to deliver high-quality solutions efficiently

• Team Player: You foster effective collaboration between engineering teams and stakeholders, ensuring alignment and seamless handoffs

• Leveraging AI: You are enthusiastic about leveraging current and new AI solutions to streamline operations and maximize output, staying at the forefront of changes in AI tools to enhance your role and productivity
