Site Reliability Engineer - SRE Fleet

The SRE Fleet team is responsible for maintaining the stability, scalability, and efficiency of the infrastructure that powers our global cloud platform. As a team of six engineers distributed across the US, Canada, and the UK, we combine deep infrastructure expertise with a strong focus on automation, reliability, and operational excellence. We are one of several SRE teams working together to support a platform that serves more than 500,000 customers and manages over 18 million devices worldwide.

The team operates with a high degree of autonomy, giving engineers the opportunity to drive both critical initiatives and grassroots improvements that solve real operational challenges. One of our most exciting areas of focus is expanding our ability to build highly automated regional, sovereign, and isolated cloud environments that support new markets and evolving regulatory requirements.

Everyone on the team has a voice, and engineers are encouraged to identify problems, propose solutions, and take ownership of improvements that make the platform more reliable and easier to operate.
