• Create maintainable, testable code and contribute to automated testing at the appropriate levels.
• Participate in code reviews, technical discussions, and documentation that help the team move quickly without sacrificing quality.
• Participate in the team’s upkeep rotation, including monitoring, debugging, and resolving production issues.
• Support safe releases and improve observability, reliability, performance, and product health over time.
• Collaborate with teams including Finance, Marketing, and SRE.
• Identify opportunities to automate recurring work and fix problems at their root.
• Use AI-assisted engineering tools thoughtfully in your daily work, for example to explore solutions, generate or improve code, create tests, investigate issues, and document systems.
