Senior Site Reliability Engineer

Site Reliability Engineer (SRE)

As a Site Reliability Engineer (SRE), you will play a critical role at the intersection of software engineering and infrastructure operations. This position is ideal for engineers who are passionate about automation, systems design, and building scalable, reliable platforms.

In this role, you won’t be limited to just managing cloud infrastructure—you will take ownership of the platform's overall health, performance, and developer experience. Your work will span:

• Cloud Infrastructure Management: Architect, implement, and maintain robust and secure infrastructure in a cloud-native environment using Terraform. Ensure high availability, scalability, and resilience of systems.
• CI/CD and Deployment Automation: Design and improve continuous integration and continuous delivery pipelines that empower development teams to ship software reliably and rapidly.
• Observability & Monitoring: Implement end-to-end observability tooling—including metrics, logging, distributed tracing, and alerting—to provide real-time insight into platform performance and help reduce mean time to detection and resolution.
• Platform Quality & Reliability: Champion best practices for reliability, scalability, and performance across engineering teams.

You’ll collaborate closely with developers, security engineers, and product stakeholders to ensure systems meet both technical and business goals.
