Senior Site Reliability Engineer
Upsun is seeking a Senior Site Reliability Engineer to lead the evolution of their cloud application platform into a proactive, automation-driven Site Reliability Engineering (SRE) model. This role involves enhancing system reliability, scalability, and operational efficiency across multi-cloud environments. The Senior SRE will collaborate closely with engineering, product, and platform teams to integrate reliability and performance into every stage of the software delivery lifecycle.
Key responsibilities include architecting and elevating system monitoring, alerting, and logging using tools like Prometheus, Grafana, and the ELK Stack, and establishing actionable Service Level Indicators (SLIs) and Service Level Objectives (SLOs) aligned with core business metrics. The role also involves automating infrastructure and workflows to eliminate operational toil by designing and implementing resilient, automated solutions using Infrastructure as Code (IaC) tools such as Terraform and Ansible across AWS, GCP, and Azure. Additionally, the Senior SRE will optimize Continuous Integration/Continuous Deployment (CI/CD) pipeline architectures for fast, secure, and zero-downtime releases, ensuring infrastructure resilience during high-volume deployment cycles.
The ideal candidate will have over five years of experience in Site Reliability Engineering, Cloud Operations, or DevOps, with a proven track record of owning reliability for production platforms at scale. Strong proficiency in Go or Python is required to build custom automation tools, custom controllers, or SRE platform components beyond basic shell scripting. Advanced hands-on knowledge of Linux operating system internals, kernel parameters, networking protocols, performance profiling, and system troubleshooting is essential. Expertise with cloud providers such as AWS, GCP, Azure, or OpenStack, along with experience in declarative infrastructure tools like Terraform, is necessary to manage distributed systems.
Upsun offers a flexible work environment with fluid career paths, encouraging internal mobility and celebrating a multicultural team. The company is committed to open source and fosters an open, welcoming environment. Upsun's core values include making a positive impact, aiming for the stars, and caring for each other. This role provides an opportunity to lead critical engineering workstreams that enhance system reliability and performance, contributing to the company's mission of providing predictable performance, secure environments, real-time observability, and AI-ready features.
