Proficiency with scripting languages like Python and Bash.
Knowledge of systems deployment and maintainence, including setting up CI/CD and working alongside Software Developers, monitoring logs, dashboards, etc.
Experience integrating with a wide variety of external tools and services

An established track record of deploying and maintaining systems.
Experience with microservices and decomposition of monolithic architectures
Proficiency in automated tests.
Proficiency with the linux ecosystem
Experience in deploying systems to production on cloud platforms such as AWS
