The Role:

Sauce Labs is looking for a Senior Systems Engineer to join our high-performance Ops Team. This critical role is responsible for the architecture, operation, and massive scaling of the hybrid cloud infrastructure and software that powers Sauce Labs, launching over 10 million VMs a month. You will be a key decision-maker in how we evolve our platforms for the future, with a strong focus on building and optimizing our extensive Kubernetes environment.

Responsibilities:

• Kubernetes and Cloud Native Architecture: Lead the design, deployment, and lifecycle management of highly available, scalable Kubernetes clusters across both our data centers and public cloud providers (GCP, AWS).
• Infrastructure Automation: Write and maintain expert-level infrastructure-as-code using Terraform to deploy and manage services in our hybrid cloud environment. Develop robust automation and self-service tooling in Python or Go to empower engineering teams.
• System and Hardware Operations: Install, configure, debug, and manage a diverse range of hardware and systems in our global data centers, including Dell, SuperMicro, storage arrays (NAS/SAN), and custom mobile device appliances.
• Scalability and Performance Engineering: Creatively solve complex scaling challenges within our rapidly expanding environment. Optimize hardware, hypervisor (KVM-Qemu), and Kubernetes configurations to enhance performance and efficiency.
• Observability and Monitoring: Engineer and enhance our observability stack (Prometheus, Grafana) to provide deep insights into the health and performance of our Kubernetes clusters, applications, and underlying infrastructure.
• Disaster Recovery and Resiliency: Design, implement, and maintain robust disaster recovery strategies for critical production services, with a focus on multi-cluster and multi-region Kubernetes deployments.
• Bare Metal Provisioning: Automate the deployment and lifecycle management of operating systems on bare metal servers using tools like PXE and Foreman.
• Documentation and Runbooks: Create and maintain clear, comprehensive documentation, architectural diagrams, and NOC runbooks for the environments you manage.
• Troubleshooting: Act as a senior escalation point for complex troubleshooting of application, server, and network issues within our containerized and virtualized environments.
• On-Call: Participate in a 24x7 on-call rotation to ensure the stability and availability of the Sauce Labs platform.

Examples of Projects You Might Work On:

• Architecting and implementing a multi-cluster Kubernetes strategy using federation or service mesh technologies to improve global service delivery.
• Developing custom Kubernetes Operators in Go or Python to automate complex application lifecycle management.
• Leading the migration of a stateful, on-premise service into a resilient, cloud-native architecture running on GKE or EKS.
• Building a new pipeline-based tooling to fully automate the lifecycle of Kubernetes cluster nodes from bare metal provisioning to decommissioning.
• Driving the evolution of our Prometheus-based monitoring stack to handle ever-increasing scale and provide richer, more actionable insights for developers.

Required Skills:

• Proven ability to execute on high-level goals independently and to lead technical initiatives within cross-functional teams.
• 5+ years of experience as a Linux administrator/engineer at scale (hundreds of systems), with a deep understanding of designing and deploying highly available solutions.
• 3+ years of recent, hands-on professional experience architecting, operating, and scaling Kubernetes clusters in a large-scale production environment.
• Expertise in Configuration Management solutions, preferably Ansible, for managing infrastructure at scale.
• Strong skills in at least one programming language: Python (preferred) or Go.
• Solid experience in Linux performance tuning, profiling, and monitoring.
• Deep experience deploying and managing services in GCP and/or AWS using Terraform.
• Experience with virtualization technologies, specifically KVM-Qemu.
• A solid understanding of cloud, networking, and distributed computing concepts (TCP/IP, firewalls, VLANs, load balancing, etc.).
• Experience with testing frameworks for infrastructure automation (e.g., InSpec, Ansible Molecule).
• Familiarity with ZFS on Linux and managing storage appliances (iSCSI, NFS).
• Deep experience with modern observability tooling (Prometheus, Grafana).
• Excellent communication skills (verbal and written) and the ability to collaborate effectively across all levels of the organization.
• Familiarity with software engineering best practices and agile methodologies.

We are a hybrid workplace that recognizes the importance of flexibility while valuing in-person collaboration and relationship building. As a result, Saucers located near an office location must be able and willing to come into the office. Those hired remotely must be able and willing to travel to an office as required by the specific role.
