Senior Backend Engineer - NodeJS (SDE 3)

The Role

• Hold yourself and your team to high engineering standards, and promote best practices. 
• Care deeply about code quality, extensibility, and testability. 
• Understand trade-offs between speed, tech debt, and product delivery. 
• Communicate clearly about technical topics, product implications, and progress. 
• Are empathetic to a diverse group of users and team members, and thrive in a collaborative environment.
