Senior Site Reliability Engineer, Fleet Management
Senior SRE on the Fleet Management team develops and maintains scalable Kubernetes runtime environments, provides internal support to engineering teams, and participates in 24/7 on-call with a focus on automation and blameless post-mortems. Requires 6+ years experience with distributed systems, containerization, and Go/Python proficiency.
About the job
Responsibilities
- Contribute to developing and maintaining a scalable and secure runtime environment on top of Kubernetes that supports product needs across MongoDB
- Provide internal support for our Kubernetes ecosystem, partnering with engineering teams to help them solve domain-specific problems
- Participate in a 24/7 on-call rotation to resolve critical issues
- Prioritize blameless post-mortems and dedicate engineering time to systemic fixes, ensuring you aren’t paged for the same issue twice
Requirements
- 6+ years of experience in software development and operating distributed systems
- Proficient in Go, Python, or a similar language, with a strong commitment to code quality and testing practices (writing unit, integration, and E2E tests)
- Deep experience using and extending containerization technologies, preferably Kubernetes
- Solid understanding of Linux operating system internals and networking concepts (e.g., filesystems, TCP/IP, DNS, TLS)
- Customer focused mindset, treating internal developers as your primary users
- Strong operational ownership, including a track record of debugging complex production issues and driving them to resolution
- Prefer automation over manual processes ("allergic to ops work")
Nice-to-haves
- Designing and implementing secure, multi-tenant runtime environments from first principles
- Proficiency with Kubernetes ecosystem tools such as Helm, Kustomize, Gatekeeper, Kyverno, and CRDs/Operators, CRI, CSI
- Expertise in cloud infrastructure platforms, including AWS, GCP, or Azure
- Proficiency in provisioning infrastructure using tools like Terraform, Crossplane, and AWS Controllers for Kubernetes (ACK)
