Staff Python / PyTorch Developer

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

The Inference ML Engineering team at Cerebras Systems is dedicated to enabling our fast generative inference solution through simple APIs powered by a distributed runtime that runs on large clusters of our own hardware. Our mission is to empower enterprises, developers, and researchers to unlock the full potential of our platform, leveraging its performance, scalability, and flexibility.

As a Senior Software Engineer on the Inference ML Engineering team, you will design and implement APIs, machine learning features, and tools that enable state-of-the-art generative AI models to run efficiently on our custom hardware. You will collaborate with cross-functional teams to build scalable, high-performance inference solutions while helping shape the evolution of our ML ecosystem.

Responsibilities

• Drive and provide technical guidance to a team of software engineers working on complex machine learning integration projects.

• Design and implement ML features (e.g., structured outputs, biased sampling, predicted outputs) that improve performance of generative AI models at inference time.

• Design and implement high-throughput, low-latency multimodal inference models that support delivery of image, audio, and video inputs and outputs.

• Maintain our scalable serving backend for handling many concurrent requests per minute.

• Scale our inference service by implementing detailed observability throughout the entire stack.

• Analyze and improve latency, throughput, memory usage, and compute efficiency on the service and the implementation of various features.

• Optimize software to accelerate generative LLM inference by achieving high throughput and low latency.

• Stay up-to-date with advancements in machine learning and deep learning, and apply state-of-the-art techniques to enhance our solutions.

• Evaluate trade-offs between different approaches, clearly articulate design choices, and develop detailed proposals for implementing new features.

• Uncover, scope, and prioritize significant areas of technical debt across the software stack to ensure continued high quality of the inference service.

• Build and maintain robust automated test suites to ensure software quality, performance, and reliability.

• Contribute to an agile team environment by delivering high-quality software and adhering to agile development practices.

• Lead cross-functional initiatives across the company to deliver high-quality inference solutions.

Skills & Qualifications

• Bachelor's, Master's, or PhD in Computer Science, Computer Engineering, Mathematics, or a related field.

• 8+ years of experience in large-scale software engineering, with a focus on deep learning or related domains.

• Proficiency in Python for building and maintaining scalable systems.

• Advanced proficiency in C++, with an emphasis on multi-threaded programming, performance optimization, and system-level development.

• Demonstrated experience driving cross-functional projects.

• Experience building and scaling large-scale inference systems for LLMs or multimodal models.

• Familiarity with LLM serving frameworks, such as vLLM, SGLang, and TensorRT-LLM.

• Solid understanding of software architectural patterns for large-scale, high-performance applications.

• Hands-on experience with ML frameworks, such as PyTorch, and a strong understanding of their underlying architectures.

• Strong problem-solving skills, with the ability to balance technical depth with practical implementation constraints.

• Exceptional communication and presentation skills, with the ability to work both independently and collaboratively across multidisciplinary teams.
