Principal Engineer

Join our team as a Principal Engineer, where you will lead the design of complex, distributed micro-services and platforms. You will ensure alignment between architecturally inter-connected teams, drive high-level technology decisions, and take accountability for the reliability, security, and performance of our micro-services and platform capabilities. You will also establish and enforce coding standards, contribute to infrastructure-as-code, and lead the resolution of complex technical incidents.

A curious, constant learner who proactively shares knowledge via tech talks, documentation, and coaching
