• Operational experience -- comfortable supporting other departments, optimizing deployments for availability and uptime, and going deep on troubleshooting and remediation.
• Programming experience -- Bash, Python, amongst others (both reading and writing).
• Knowledge of Relational Databases (e.g. Postgres), and NoSQL DBs/systems (e.g. Redis, ElasticSearch).
• Great communication skills, both written and verbal.
• Eagerness to learn new technologies.
