SendGrid is looking for a talented and passionate individual to help manage our world-class SaaS email delivery infrastructure. You will be part of a team that ensures the reliability and performance of a large and diverse tech stack. You will directly engage with development teams to provide Ops-relevant advice and feedback, and serve as an information conduit back to other DevOps team members. Additionally, you will continually improve the velocity of our deployment pipeline through automation and monitoring.

What You’ll Do

• Take personal responsibility for the availability and reliability of our service
• Use configuration management tools to automate SendGrid infrastructure
• Identify key system metrics and ensure adequate monitoring coverage for new and existing services
• Author tools that reliably manage infrastructure. We're looking for someone to write clean, testable, re-usable code.
• Write maintainable code with extensive test coverage
• Support our existing production cluster management system while you improve it
• Work on our server image configurations, collaborating with core server engineers to optimize for task performance, reliability, failover and scale
• We're an agile, fast growing company and this job description isn't meant to be a complete list of your qualifications or all the things you'll do

About You

• A minimum of 5 years of Linux system administration experience
• A minimum of 2 years experience using configuration management tools (Chef, Puppet, Ansible, etc)
• A minimum of 2 years experience monitoring large-scale deployments (Sensu, Nagios, Graphite, OpenTSDB, etc)
• Experience with at least two of the following: Ruby, Go, Perl, Python (a lot of our current code is Ruby but we use whatever tool is best for the job at hand)
• Experience with virtualization systems: KVM, QEMU, etc.
• Strong familiarity with the SMTP protocol
• Computer Science / Engineering degree or equivalent experience
• A distributed systems foundation and a service-oriented mindset
• You've "carried the pager" before (ideally at both a startup and a large infrastructure provider) & have first-hand experience with what happens when infrastructure / tools fail
• You are a prolific coder who works well independently
• You have great communication skills
• You’ve written software tools to manage 1000+ servers
• You are conversant in the pros and cons of different clouds: Softlayer, Rackspace, etc

• You read up on and experiment with new technologies because it’s in your nature, not because it’s a job requirement
• You don’t just learn how things work, you learn why
