Job details:
Senior Site Reliability Engineer (Cloud Telephony)
Say hello to possibilities.
It’s not everyday that you consider starting a new career challenge.
RingCentral, Inc. (NYSE: RNG) is a global leader in cloud-based communications and collaboration software. We are fundamentally changing the nature of human interaction—giving people the freedom to connect powerfully and personally from anywhere, at any time, on any device. The company provides unified voice, video meetings, team messaging, digital customer engagement, and integrated contact center solutions for enterprises globally. RingCentral's open platform integrates with leading business apps and enables customers to easily customize business workflows.
We’re a $2.50 billion company that’s growing at 30+% annually and we’re expanding our Engineering Team to make sure we stay ahead of the competition. RingCentral is headquartered in Belmont, California, and has offices around the world.
We are looking for an experienced Senior Site Reliability Engineer— someone who takes ownership, solves problems independently, and treats production systems with care and respect.
You’ll join a team that keeps business-critical telephony and communication services running with 99.999% availability. We need someone who not only reacts to incidents but also anticipates them — who improves systems, automates routine tasks, and helps shape how the team works.
Key Responsibilities:
- Support and maintain Linux-based servers and telephony services in production.
- Investigate and resolve incidents in a high-load, distributed environment.
- Participate in on-call shifts and ensure the stability of systems under strict SLAs.
- Analyze service performance, reliability, and architecture bottlenecks; propose improvements.
- Work with development teams to safely deliver and validate changes before production deployment.
- Contribute ideas and help evolve team processes, automation, and monitoring practices.
Requirements:
- 8+ years of Strong hands-on experience with UNIX/Linux systems, with deep proficiency in CLI-based diagnostics, system administration, and production troubleshooting at scale.
- Good understanding of networking protocols or SIP.
- Strong hands-on experience with Kubernetes (k8s) and containerized environments.
- Proven track record of working in production environments, with a careful and methodical approach to changes (testing before deployment, rollback planning, risk mitigation).
- Understanding of high-availability systems, fault tolerance, and performance optimization.
- Experience automating tasks with Python, Golang, or Shell scripts.
- Mindset of an SRE: you treat operations as an engineering discipline and continuously look for ways to make systems more reliable and efficient.
- Good command of English (B2 or higher) — ability to communicate effectively with distributed international teams (both written and spoken).
Would be a plus:
- Deep expertise in one or more areas (please highlight your strengths in your application).
- Hands-on experience with Kamailio, Apache Kafka, Nginx, ZeroMQ.
- Experience with AWS/EKS, Terraform, and Ansible for deployment and infrastructure automation.
- Experience with CI/CD pipelines (e.g., GitLab CI, Jenkins, ArgoCD).
- Knowledge of monitoring stacks like Zabbix, TICK, ELK, Grafana.
-
What you’ll get:
- Work in a strong, experienced SRE team that maintains global infrastructure across multiple regions.
- Hands-on experience debugging Java and C++ applications in large distributed systems (Kafka, Zookeeper, Kamailio, Nginx, etc.).
- Opportunity to influence how the team works — your ideas for tools, automation, or process improvements will be heard and implemented.
- Real experience achieving five-nines availability (99.999%) in production.
- Continuous learning, complex technical challenges, and a supportive environment.
