• Guiding the technical strategy for your direct team and the broader department
• Building and iterating on backend services in Go, using PostgreSQL and DynamoDB, and implementing message-driven patterns with RabbitMQ
• Contributing across the stack, including light frontend work in our mobile app (Angular/Ionic), web app (React), and internal/admin tools, with support from frontend-focused teammates
• Owning work end-to-end: from idea and design, through implementation, testing, and deployment
• Collaborating closely with other engineers in person - whiteboarding, pairing, and iterating quickly
• Breaking down ambiguous problems into actionable tasks and identifying technical risks early
• Participating in on-call rotation and learning how to monitor and operate your work in production using Datadog and other observability tools
• Reviewing pull requests, sharing learnings, and contributing to a culture of curiosity and experimentation
• Owning the production operation, monitoring our system, and helping define SLAs/SLOs
