Staff Software Engineer, Observability

Sunnyvale, CA; Toronto, Ontario, Canada

Cerebras Systems builds the world's largest AI chip, 56 times larger than GPUs. Our novel wafer-scale architecture provides the AI compute power of dozens of GPUs on a single chip, with the programming simplicity of a single device. This approach allows Cerebras to deliver industry-leading training and inference speeds and empowers machine learning users to effortlessly run large-scale ML applications, without the hassle of managing hundreds of GPUs or TPUs.  

Cerebras' current customers include top model labs, global enterprises, and cutting-edge AI-native startups. OpenAI recently announced a multi-year partnership with Cerebras, to deploy 750 megawatts of scale, transforming key workloads with ultra high-speed inference. 

Thanks to the groundbreaking wafer-scale architecture, Cerebras Inference offers the fastest Generative AI inference solution in the world, over 10 times faster than GPU-based hyperscale cloud inference services. This order of magnitude increase in speed is transforming the user experience of AI applications, unlocking real-time iteration and increasing intelligence via additional agentic computation.

About The Role

We are seeking a talented Platform Software Engineer to join the team building the Cerebras Inference Platform. You will be instrumental in designing, developing, and operating the core backend services and APIs that power the Inference platform. You'll build the software that allows customers to seamlessly deploy, manage, and serve inference workloads on dedicated Cerebras hardware.  

Responsibilities
  • Set Technical Direction: Own the long-term architecture and roadmap for the observability platform across all pillars (metrics, logs, traces, and events). Drive adoption across the engineering organization through RFCs, design reviews, and close partnership with stakeholders.
  • Build for Cerebras-Scale: Design telemetry pipelines that handle high-cardinality, high-frequency data from thousands of Wafer-Scale Engines, large Kubernetes clusters, and the storage and networking fabric connecting them. Solve ingestion and query performance problems that break conventional approaches.
  • Drive Reliability Across the Organization: Partner with Engineering, SRE, Hardware, and ML Infrastructure teams to define SLOs, build alerting strategies, and create tooling that accelerates root cause analysis and reduces MTTR. Make it easy for any engineer to understand system health and diagnose failures.
  • Bridge Hardware and Software Observability: Work with engineering teams accross the stack to surface critical hardware health signals into a unified observability layer alongside software metrics.
  • Shape Developer Experience: Design and implement instrumentation libraries and standards (OpenTelemetry) that make rich observability the default for every service, not an afterthought. Establish conventions that scale across teams.
  • Mentor and Grow Engineers: Raise the technical bar across the organization. Mentor senior engineers, influence engineering practices across team boundaries, and foster a culture of operational excellence.

Qualifications
  • 8+ years of software engineering experience, with 4+ years building or operating observability/monitoring platforms at significant scale (millions of active time series, petabytes of log data).
  • Deep expertise in the open-source observability ecosystem. You have operated, tuned, and extended systems like Prometheus, Thanos/Cortex/Mimir, Elasticsearch/ClickHouse, or Loki and understand their internals, failure modes, and cost characteristics.
  • Experience with OpenTelemetry for instrumentation across a polyglot services environment.
  • Proficiency in Go preferred, with strong experience in Python. You write performant, concurrent systems code, not just glue scripts.
  • Strong distributed systems and Kubernetes expertise: sharding, replication, consistency models, monitoring K8s itself and the workloads running on it, and the tradeoffs involved in building reliable data pipelines at scale.
  • Experience with observability cost management and capacity planning at scale.
  • Track record of setting technical direction and driving adoption across multiple teams. You operate effectively with ambiguity and can translate business needs into technical strategy.

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
