This relatively new team is building performant, multi-tenant distributed storage services that both enhance today’s Atlas storage stack and enable more customer workloads to run more efficiently.\nYou will partner with the teams building these storage services to define SLOs, shape capacity plans, and ensure the reliability, durability, and operational safety of the storage layer that underpins Atlas. You’ll join a small, senior team of SREs as founding members of this organization, playing a crucial role in executing on a multi-year roadmap for MongoDB’s cloud storage architecture.\nThis role can be based out of our Toronto or Montreal office or remotely in the Canada while physically based in an Eastern or Central time zone location. \nThe ideal candidate should\nHave 6+ years of experience working on software development and operating distributed systems\nProficiency in Python, Go, or a similar language\nHave operated or supported stateful storage or database systems at scale, and are comfortable with durability, consistency, and recovery trade-offs.\nPossess a customer-focused mindset\nValue efficiency in processes and operations\nPrefer automation over manual processes. We are a small team of software engineers with a strong bias towards software solutions to avoid toil\nExperience using and extending containerization technologies, particularly Kubernetes, to enhance application agility, optimize resource utilization, and accelerate time-to-market\nExpertise in cloud infrastructure platforms, including AWS, Google Cloud Platform (GCP), or Azure\nUnderstanding of Linux operating system internals and networking concepts (e.g., TCP/IP, DNS, TLS, routing)\nResponsibilities \nWork on our multi-tenant distributed storage systems, balancing long-term strategic infrastructure goals with immediate engineering needs\nBuild for reliability, making services and infrastructure available, resilient, fault-tolerant, and self-healing\nIdentify and configure key metrics to detect incidents and quantify service health, availability, and performance\nParticipate in a 24/7 on-call rotation to resolve issues involving the storage infrastructure\nBecome an expert in infrastructure performance, helping us optimize from the application level all the way to the kernel\nStrong candidates may also have experience with:\nLeading major architectural shifts, such as moving from legacy storage stacks to new multi-tenant storage architectures, including planning and executing large-scale data and workload migrations with tight availability and durability requirements\nManaging and scaling infrastructure across multi-cloud environments (AWS, GCP, or Azure)\nDesigning secure, multi-tenant runtime environments at scale\nAbout MongoDB\nMongoDB is built for change, empowering our customers and our people to innovate at the speed of the market.
