Hi, I’m Terry – Director of Engineering, Platform Experience. Customer.io is looking for a collaborative Senior Site Reliability Engineer (SRE) who loves solving interesting puzzles and is excited to help us build out a scalable, reliable platform that our customers love.

The other members of our site reliability team have backgrounds in a wide variety of industries, from Telecom to Gaming, with 10 – 20 years of experience in DevOps. We believe that embracing our unique perspectives and expertise is key to our success as a collaborative team.
Our mission is to provide a best-in-class message management system to help our customers quickly craft meaningful content that reaches their customers. A core component of our Journeys application is delivering email, a critical service our customers expect to be available and performant. Building a repeatable, scalable and high-performant infrastructure for our MTA (mail transfer agent), we can enhance the customer experience by ensuring email is delivered with expected accuracy and performance while providing improved observability.
We are seeking product-minded, empowered individuals who work collaboratively with their peers on interesting problems, and get those solutions into the hands of customers quickly. We value diversity, attracting the best people in the world to serve as colleagues. Our flexibility and freedom to work from anywhere in the world enable you to craft a work environment in which you can do your best work.
As a Senior Site Reliability Engineer, you will:
- Design, build, and maintain core MTA infrastructure pieces that allow Customer.io scaling to support real-time processing and delivery of billions of messages
- Plan the growth of Customer.io’s MTA infrastructure
- Automate the deployment process to make it as boring as possible
- Be on our on-call rotation to respond to Customer.io availability incidents and provide support for technical support engineers with customer incidents
- Ensure monitoring and alerting, alert on symptoms and not on outages
- Document every action so lessons learned turn into repeatable actions and then into automation
- Debug production issues across services and levels of the stack
- Take an active role in a friendly and supportive team that encourages you and the entire company to grow as individuals, professionals, and teams
- Learn, practice, and share with your coworkers through code review, pair programming, team collaboration, and training to help improve our collective knowledge and best practices together
What we’re looking for:
The role of Senior Site Reliability Engineer has the following requirements:
- A collaborative mindset backed by excellent communication skills and a desire to help us make great decisions in an empathetic and respectful way

- A solid understanding of problems of scalability and experience deploying and managing distributed MTAs on cloud infrastructure
- Demonstrated track record of building and maintaining relationships within the MTA industry.
- Proven experience building infrastructure via code and automating operational toil
- Deep knowledge of UNIX environments and the ability to apply modern collaborative development practices. Go experience is nice to have, but most of our engineers have succeeded while picking it up on the job
- A self-starter who values synchronous and asynchronous work
- Experience working with Google Cloud Platform would be nice to have
- Preferably based in European time zones.
