Senior Cloud Platform Engineer

Senior Cloud Platform Engineer

Join SambaNova Systems, a leader in frontier tech, and help shape the future of AI computing. We are disrupting the AI and high-performance computing space with our integrated hardware and software platform. Our DataScale systems and SambaFlow software are pushing the boundaries of what's possible with generative AI and large language models. We are a team of passionate innovators tackling some of the world's most challenging computational problems.

As a Senior Cloud Site Reliability Engineer (SRE) specializing in our AI Inferencing Service, you will be the guardian of its reliability, performance, and scalability. You will bridge the gap between software development and operations, applying an engineering mindset to solve operational challenges. Your primary focus will be ensuring our inference endpoints have exceptional uptime, low-latency response times, and efficient resource utilization, directly impacting the experience of our customers and the success of our AI products. This role includes participating in a shared on-call rotation to maintain 24/7 service reliability.

Service Ownership & On-Call: Take shared ownership of the production inferencing service, including its availability, latency, performance, efficiency, change management, monitoring, emergency response, and capacity planning across multiple regions. This includes implementing and supporting AI infrastructure in new regions, such as Asia, Europe, and Latin America, to support the growth of our business. Participate in a balanced on-call rotation to provide 24/7 support for the service.

On-Call & Work-Life Balance: We believe a sustainable on-call schedule is critical for long-term success and team health. Our on-call philosophy is built on the following principles:

• Balanced Rotation: The on-call rotation is shared equally across the team, typically following a primary/secondary (follow-the-sun) model to ensure no single person bears a disproportionate burden.
• Focus on Prevention: We invest heavily in automation, robust testing, and system design to prevent pages before they happen. The goal of on-call is not to heroically fight fires, but to manage rare, complex failures and use those learnings to make the system more resilient.
• Actionable Alerts: We have a strict policy against alert fatigue. Alerts must be actionable and require immediate human intervention.
• Incident Management: Lead the response to incidents affecting the inferencing service, driving blameless post-mortems and implementing corrective actions to prevent recurrence.
• Monitoring & Alerting: Develop and maintain advanced monitoring, alerting, and dashboarding (using tools like Prometheus, Grafana, Datadog) to gain deep insights into service health, model performance (e.g., latency, throughput, error rates), and accelerator utilization. A key responsibility is ensuring alerts are actionable and have a low false-positive rate, minimizing on-call fatigue.
• Performance & Scalability: Proactively identify and eliminate performance bottlenecks. Design and implement auto-scaling policies to handle variable inference loads cost-effectively. Use insights from on-call incidents to drive improvements that enhance system stability and scalability.
• Infrastructure as Code (IaC): Manage and evolve our cloud infrastructure (on AWS, GCP, and/or Azure along with on-prem) using tools like Terraform and Ansible, ensuring it is secure, repeatable, and scalable.
• CI/CD & Automation: Champion automation by building and improving CI/CD pipelines for the seamless and safe deployment of new model versions and service updates. A core goal is to automate manual toil identified during on-call shifts, reducing future operational overhead.
• Capacity Planning: Forecast infrastructure needs based on product roadmaps and usage trends. Work with finance and engineering teams to manage cloud costs and optimize spending.
• SLOs & SLIs: Define, measure, and report on Service Level Objectives (SLOs) and Indicators (SLIs) for the inferencing platform, using data to drive prioritization and reliability investments.

What We're Looking For (Must-Haves):

• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
• 5-8+ years of experience in a Site Reliability Engineer, DevOps, or related role supporting a large-scale, customer-facing service in a public cloud environment (AWS, GCP, Azure).
• Strong programming/scripting skills in languages like Python, Go, or Java.
• Proven experience with containerization and orchestration technologies (Docker, Kubernetes).
• Deep understanding of monitoring and observability principles and tools (e.g., Prometheus, Grafana, ELK Stack, Datadog).
• Solid experience with Infrastructure as Code (e.g., Terraform, CloudFormation).
• Familiarity with CI/CD principles and tools (e.g., Jenkins, GitHub Actions, ArgoCD).
• Excellent problem-solving skills and a systematic approach to troubleshooting complex distributed systems.

What Will Make You Stand Out (Nice-to-Haves):

• Experience in a hybrid environment bridging cloud and on-premise/data center infrastructure.
• Direct experience supporting ML/AI inferencing services in production.
• Familiarity with GPU-accelerated computing and optimizing workloads for NVIDIA GPUs for purposes of mapping to RDUs.
• Knowledge of model serving frameworks like vLLM, SGLang or Ray.
• Understanding of MLOps principles and practices.
• Experience with managing and tuning databases (SQL or NoSQL) and caching systems (Redis, Memcached).
• Strong Linux/Unix system administration fundamentals.
