• Build and maintain models for growth and capacity planning.

• Tune large-scale data clusters for optimal performance and efficiency.

• 24/7/365 on-call rotation.

• Own the day-to-day health, uptime, monitoring, and reliability of all data platforms and database systems.

• Work closely with project management and engineering peers to develop innovative technical tools and solutions.

• Identify tactical issues and react to emerging areas of concern.

• Adhere to a DevOps philosophy by evangelizing communication, collaboration, and integration with software development teams.

• Think long-term and be unsatisfied with band-aids.

• Identify unnecessary complexity and remove it.

Requirements:

• At least four years experience in Data or Database Operations, Site Reliability Engineering, System Administration or equivalent roles.

• At least three years experience maintaining a production infrastructure hosted on AWS, GCP, or equivalent public cloud providers.

• Demonstrated experience in network and large scale UNIX system troubleshooting and maintenance practices.

• Capability to script and automate solutions with strong competence in at least one programming language.

• Solid knowledge of UNIX command-line tools.

• Strong understanding how to manage public cloud services and tasks, such as: load balancing, automation through provider API, VPC, serverless computing (Lambda, GCF), backup/restore procedures, and managing policies and resources.

• Firm grasp of storage protocols and filesystems.

• Deep experience installing and managing one or more of the following: Hadoop clusters and related services, RDBMS platforms (e.g. MariaDB / MySQL, PostgreSQL, Vertica), distributed data systems (e.g. Riak, Druid, Kafka)

• Implementation and management of monitoring and metrics tools (e.g. Nagios, Graphite, Grafana, SumoLogic).

• Excellent organizational skills and the ability to work in a fast-paced and hectic work environment.

• Capable of technical deep-dives into code, networking, systems, and storage with SRE and software engineering.

• Willing to occasionally travel to different office locations.

• Knowledge and interest in the latest system architecture trends.

• Ability to learn and understand new systems.

• Ability to communicate effectively and write accurate, clear documentation.

• Humility and integrity.

Nice to Have:
