An ideal candidate would have an ability to analyze and resolve complex infrastructure resource and application deployment issues.
Essential qualities:
  • Bachelor's degree in Computer Science (or equivalent) or higher degree
  • Excellent Linux skills and experience with running high-available Ruby on Rails applications (99.95% is our SLA right now. Our internal target is 99.99%. Currently we are around 99.98%. With the additional SRE hire we would like to improve our infrastructure to reach > 99.99%)
  • Experience with our current stack - RoR, Nginx, Passenger, MySQL, Redis
  • Good understanding of configuration management tools like Chef and monitoring tools like DataDog
  • Working knowledge of Javascript and Ruby on Rails

Bonus Points

  • Experience with global failover and load balancers
  • Working knowledge of MySQL replication
  • Security related work background or CISSP certification

Our current infrastructure environment/HL figures and about team:
  • We are using AWS, Armor and Rackspace as our cloud providers. Armor is a specialized provider for health and financial data workloads and runs the majority of our production workloads. All servers are cloud servers based on CentOS 7.
  • HL figures: we serve around 3000 Requests per minute with peaks about to 5000 requests per minute.
  • We have 2 full-time members in the DevOPS / SRE team. One of them is a dedicated MySQL DBA. In additional to those two, our lead engineer and CTO are both available to help out and provide guidance

Infrastructure goals
1. Short-term
  • Improve alerting on our Elasticsearch cluster (e.g abnormal changes in throughput)
  • Deploy and maintain HAProxy load balancer
  • Ability to perform regular security checks

2. Mid-Term
  • Move our backup DC from Armor to AWS, to diversify the risk of using a single hosting provider: This will include setting up and maintaining an Intrusion detection system (e.g OSSEC). Evaluating WAF/FIM solutions, etc. for PCI and HIPAA compliancy
  • Setup High-Availability MySQL cluster using Orchestrator/ProxySQL
  • Reach uptime of > 99.99%

Technology Stack and Tools you will be working with

  • Ruby on Rails (version of Rails 5.2.3. We use NGINX/Phusion passenger for running the Rails application and capistrano for deployment)
  • EmberJS/ReactJS (this is about basic knowledge of deploying and diagnosing issues related to Single Page Applications (Cloudfront, S3, ability to isolate the origin of a problem — it's not about writing or fixing the Javascript code))
  • Nginx
  • Phusion Passenger
  • Capistrano (we're using Capistrano 3.11. as part of our CI/CD pipeline; for the mobile apps we use CircleCI and BuddyBuild in the build environment)
  • MySQL
  • Redis
  • Kibana (we use the ELK stack for log aggregation & we would like to extend that stack to allow automated alerts based on patterns)
  • Chef
  • DataDog
