Software Engineer, Inference Platform

Cerebras; Toronto; Hybrid; CAD 120,000 - 180,000; Full time

Job summary

Cerebras Systems is hiring a Software Engineer for our Inference Platform team. You will help design and maintain the orchestration layer that runs inference on datacenter clusters, connecting cloud components with ML services.

You will address Kubernetes operators, security policies, and CI/CD, owning major technical areas and roadmap. Sunnyvale or Toronto is acceptable, joining a team building one of the fastest AI platforms.

Qualifications

• 3+ years of software engineering experience building and operating large-scale distributed systems.
• Experience with Kubernetes.
• Experience building highly available, latency-sensitive systems at scale.
• Security: certificates, TLS, mTLS.
• Experience optimizing latency and throughput (high-QPS).
• Proficiency in Go or C++ backend/systems.

Responsibilities

• Design, develop, test, and maintain production software across testing, CD, observability, security, networking and productionization.
• Shape the technical direction for the Inference Platform, CRDs, failure domains, service boundaries and major technical areas.
• Architect active-active systems with fast failover and clear SLOs; improve latency, throughput and resilience.
• Write and review production code in critical parts of the platform; set technical bar via reviews.
• Lead on hard production issues, incident response, and capacity planning with strong operational rigor.
• Collaborate with ML, Product, Infrastructure and Cloud teams to align on architectural decisions.

Job description

Cerebras Systems builds the world's largest AI chip, 56 times larger than GPUs. This architecture allows Cerebras to deliver industry-leading training and inference speeds; 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.

Cerebras works with the leading 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.

About The Role

We're hiring a Software Engineer to help contribute to projects on our Inference Platform team. Our team primarily owns the orchestration layer that runs inference on our datacenter clusters, connecting cloud components with machine learning services. We are often the first team to face problems that haven't been solved yet, leading solutions across Kubernetes operators, service security policies, and CI/CD.

If you're interested in building the next-generation architecture of a globally distributed inference platform, we'd like to talk.

Responsibilities

• Design, develop, test, and maintain production software, with responsibilities spanning testing, continuous development, observability, security, networking, debugging, and productionization.
• Platform Direction. Help shape the technical direction for the Inference Platform, Kubernetes custom resource definitions, failure domains, service boundaries, and system evolution over time, and own the roadmap for major technical areas.
• Reliability & Performance. Architect active-active systems with rapid failover, graceful degradation, and clear SLOs. Drive system-level improvements in latency, throughput, capacity efficiency, and resilience under unpredictable demand.
• Execution on Critical Paths. Write and review production code in the most important parts of the platform. Make high-consequence architectural decisions within your area and set the technical bar through design reviews, code reviews, and sound engineering judgment.
• Production Leadership. Lead on the hardest production issues and cross-system bottlenecks. Drive observability, incident response, capacity planning, and post-incident improvement with a high standard for operational rigor.
• Technical Influence. Partner with ML, Product, Infrastructure, and Cloud teams to translate product and business requirements into scalable system designs, and drive alignment on shared technical decisions within your domain and adjacent platform surfaces.

Skills & Qualifications

• 3+ years of experience in software engineering, with experience building and operating large-scale distributed systems or cloud infrastructure.
• Experience in distributed systems, ideally with Kubernetes.
• Experience building highly available, latency-sensitive systems at scale.
• Experience with security (certificates, TLS, mTLS).
• Experience optimizing latency, throughput, and efficiency in high-QPS systems. Experience with TTFT and tail-latency reduction is a strong plus.
• Strong proficiency in backend or systems languages such as Go or C++.

Preferred Skills & Qualifications

• Experience with ML inference infrastructure, model serving systems, or GPU-accelerated workloads.

Location

Open to Sunnyvale or Toronto.
