Site Reliability Engineering Manager 🔥


Hi, I'm Matthew, CTO at Customer.io [1]. I'm looking for a Site Reliability Engineering Manager to join our growing Engineering Management team.

At Customer.io, Site Reliability Engineering (SRE) are the folks that help keep our production systems running and secure. As the SRE Manager, you will be responsible for ensuring that the team meets this mandate. You will do this by providing structure and direction to a talented team of SREs through people management, career guidance, and overall project management.

Our small, remote-first team is fun-loving, passionate, and highly effective. We have an experienced group of engineers, strong technical leads, a proven architecture, and a track record of delivering major improvements with stability. Members of our site reliability team have backgrounds in a wide variety of industries, from Telecom to Gaming, and we believe that embracing our unique perspectives and expertise is key to our success as a collaborative team.

As the SRE Manager at Customer.io, you will...
  • Ensure that core infrastructure pieces are designed, built, and maintained to allow Customer.io scaling to support real-time processing and delivery of billions of messages
  • Plan the growth of Customer.io’s infrastructure
  • Use data to make informed decisions about priorities, and to measure the cost of problems and the impact of solutions
  • Improve the deployment process to make it as boring as possible
  • Ensure monitoring and alerting trigger on symptoms, in advance of outages
  • Be on the escalation path of our on-call rotation to respond to Customer.io availability incidents and provide assistance for our customers team
  • Mentor, nurture, and grow a team of SREs
  • Champion our culture. We strive to be inclusive, cooperative, and empathetic
  • Recruit and hire new team members, with an emphasis on increasing our diversity
  • Work directly within your squad to create accountability for delivery timelines, promote healthy work culture, and ensure system reliability and uptime

We're looking for someone who has...
  • Experience as a Site Reliability Engineering Manager in the SaaS industry
  • Genuine excitement about managing and developing people. While you started as an SRE, you've committed to management as your career path
  • Experience in managing and working with RDB systems, preferably MySQL
  • A solid understanding of problems of scalability and experience deploying and managing distributed applications on cloud infrastructure
  • Deep knowledge of UNIX environments and ability to apply modern collaborative development practices
  • Strong technical foundation in database technologies, distributed systems, and scaling solutions
  • Ideally, you've had an opportunity to manage your reports remotely, but this is not a requirement
  • Located in North/South America hours (UTC -4 to -7)

We are offering a starting salary of $126k - $150k USD depending on experience and subject to market rate.

  • 20 days PTO - we offer 20 vacation days (in addition to holidays and sick days) so that you can unwind, unplug, and recharge

  • Co-working space reimbursement - Up to $300 USD per month for those times you'd prefer to work in a co-working environment
  • Professional development allowance - Up to $2,000 USD reimbursement per year to use on conferences, books, classes, or workshops - anything that will help you develop your skills
  • 1 month paid sabbatical after four years at Customer.io - to treat yourself to a vacation, or spend however you choose
  • Company retreats twice a year - we typically get together IRL every spring and fall, but most recently had an amazing virtual retreat!
  • Flexible schedule, work anywhere you want! - as long as you have a reliable internet connection and some overlapping work time with your manager, you can work where and when you want

All final candidates will be asked to complete an employment and education verification authorization form (which allows us to verify your job history and education listed on your resume) as part of our pre-employment process.

Customer.io recognizes the stifling impact of systemic injustice on diverse communities. We commit to using our influence to increase inclusion and equity within the tech industry. We strive to build an inclusive team culture, implement bias-free hiring practices, and develop community partnerships to expand our global impact.
