• Analyze and understand performance and scalability bottlenecks in the system and solve them
• Deal with issues from logical representations of the execution plan to efficient resource management, all the way down to highly parallel vectorized execution
• Design and implement critical high-performance systems to handle the ever-growing request rate on our database
• Evangelize best practices in database usage and end-to-end architecture
• Set an example for and mentor and grow your teammates
• Recognize and take action to improve the developer work environment
• Write clean, understandable, and testable code
• Provide feedback on the designs and code of peers
• Manage individual project priorities, deadlines, and deliverables
• Document development procedures, concepts and knowledge
• Build, launch, and maintain features in production
• Help define a fun and inclusive engineering culture

The qualifications you need

• BS in Computer science; Masters or Ph.D. preferred
• 8+ years of hands-on software engineering experience
