• Simplify infrastructure and architecture over time by identifying bottlenecks, reducing operational complexity, and making systems easier for engineers to reason about.
• Improve how engineers build and ship software by strengthening CI/CD, observability, and developer tooling across the platform.
• Take ownership of key technical outcomes from initial design through production rollout and ongoing operation.
• Work with leaders during company planning cycles to discuss technical improvements we need to make.
• Partner closely with product and engineering teams to deliver technical solutions that unlock new product capabilities.
• Work in the open by sharing context, writing clear technical proposals, and helping teams align around thoughtful solutions.
• Raise the engineering bar by mentoring teammates, sharing knowledge, and helping the team build systems we’re proud to operate.
