CircleCI seeks a Senior Site Reliability Engineering to optimize the high-performance and scalable infrastructure we run on AWS and GCP in order to improve our gross margin and drive efficiencies in our operations. You will contribute to building a new team within Platform Engineering charged with reducing our cloud spend without constraining the organization’s ability to ship and iterate on customer value. 

In this role, you will balance the tradeoffs between agility and cost efficiencies with your knowledge of all factors that affect cloud provider pricing. You will identify and implement efficiency solutions that directly impact the bottom line by working closely with product delivery teams on best practices, reducing waste in spending and reviews of new features with an eye towards cost savings. This is a unique opportunity to work towards objectives with very clear metrics. We have a north star and will have real-time insight to our progress.

Initially, your responsibilities will include:

• Monitoring, reporting and remediating abuse of our free tier 
• Implementing a data lifecycle for CircleCI user assets
• Delivering tooling to reap orphaned resources 
• Identifying and recommending savings opportunities through technology innovation, engaging in reserved capacity purchases or changes to business processes 
• Developing billing and usage monitoring, thresholds, and alerting
• Reviewing new CircleCI features to ensure cost efficiency as part of architecture reviews 

What we’re looking for: 

• Experience with cloud services and virtualization, e.g. AWS, GCP, etc., and demonstrated ability to install, configure and manage virtualized systems
• Understanding of Docker or evolving container management platforms like Kubernetes or Nomad 
• Understanding of standard networking protocols and components such as: TCP/IP, HTTP, DNS, ICMP, the OSI Model, Subnetting, and Load Balancing
• Proficiency in one or more of: Go, Java, Clojure, Python, C or C++
• Comprehensive knowledge of the internal workings of at least one of: Postgres, Mongo, Redis, RabbitMQ
• Systematic problem solving approach, coupled with a strong sense of ownership and drive
• An understanding of how to build observability into systems to ensure issues can easily be identified and fixed
• 4+ years of experience
• Ability to work transparently on a distributed team
• You value developer productivity and can make appropriate trade offs on cost vs velocity and autonomy 

Additional qualifications we’d love to see: 

• You care deeply about the experience and satisfaction of users (internal and external)
• You have experience with Continuous Integration and Continuous Delivery methodologies and tools
• Systems Engineer and/or DevOps background
• You have a drive to create efficient systems and processes
