Senior Site Reliability Engineer (SRE)

We are building a cloud-native compute orchestration platform supporting large-scale, compute-intensive engineering workloads across simulation, verification, and backend pipelines. The platform underpins engineering productivity and runs at scale, with resilience and efficiency at its core.
This role sits within the Productivity Engineering - Technical Capacity and Analytics team, a cloud-focused team enabling engineering users to migrate to and operate effectively in the cloud.
Overview:
We are seeking an experienced Senior Site Reliability Engineer (SRE) to strengthen availability, scalability, and operational maturity across the platform. This is an opportunity for someone passionate about Cloud, SRE, DevOps, and Software Engineering to make a meaningful impact across Arm.
You will design and operate distributed systems while advancing observability across AWS, Azure, and GCP. The role includes defining SLOs, evolving reliability standards, and using data-driven insights to continuously improve platform performance and stability.
Working closely with platform and engineering teams, you will embed sound operational practices into system design, improve deployment practices, and champion automation to reduce toil and improve incident response.
Responsibilities:

• Evolve observability across multi-cloud environments, enhancing monitoring, logging, alerting, tracing, and signal quality.
• Own performance and scalability validation through automated performance testing, ensuring systems operate reliably under both expected and peak demand.
• Improve deployment safety and release confidence through automated validation, reliability gates, and rollback controls in CI/CD.
• Validate resilience through structured failover testing to ensure graceful recovery.
• Lead incident response and root cause analysis, translating findings into preventative improvements.
• Define and uphold SLOs/SLAs while improving operational standards and documentation.
• Support security, audit, and compliance requirements from an operational perspective.

Required Skills and Experience:

• Experience in an SRE, DevOps, or Platform Engineering role operating production systems at scale.
• Hands-on experience with AWS, GCP, or Azure.
• Proficiency in Python, Go, Rust, or a comparable language.
• Experience defining and operating against SLIs/SLOs.
• Practical knowledge of observability across metrics, logs, tracing, and meaningful alerting.
• Experience supporting live environments using automation and data to reduce incident impact.
• Meaningful understanding of distributed systems and cloud-native architectures (e.g., Kubernetes, containers, serverless).
• Solid grasp of networking fundamentals, CI/CD practices, and modern deployment patterns.
• Familiarity with performance and load testing frameworks and profiling tools.

"Nice To Have":

• Exposure to compute-intensive or high-throughput workloads.
• Experience with performance optimization, cloud cost efficiency, and capacity planning.
• Experience designing multi-cloud architectures.
• Familiarity with infrastructure as code (e.g., Terraform).
• Exposure to regulated or compliance-driven environments.

Salary Range:
$156,500-$211,700 per year
