This architecture allows Cerebras to deliver industry-leading training and inference speeds; over 10 times faster than GPU-based hyperscale cloud inference services. \nThis 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.\nCerebras 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.\nAbout The Team\nThe ML API Quality team is responsible for the confidence behind every production release shipped to Cerebras Inference Cloud. We work closely with platform, infrastructure, ML systems, and product engineering teams to ensure that rapid iteration never comes at the expense of customer trust. Our environment spans distributed cloud systems, multi-region deployments, APIs, orchestration layers, and hardware-backed inference services.\nWe are scaling quickly. The systems are growing in complexity, traffic is increasing rapidly, and release velocity remains high. We need engineers who can build quality systems that scale with the business.\nAbout The Role\nAs a Senior Software Engineer in Test for the ML API features team, you will lead testing strategy and execution for AI/ML models, evaluating accuracy, fairness, and performance at scale. You will serve as a key technical leader in delivering and validating all software and hardware components for Cerebras API Features. You will own software components feature integration quality and drive pre-deployment and production validation for Cerebras inference solutions. In this role, you will define and champion best testing practices, establish robust debugging methodologies, and mentor junior engineers while advocating for world-class product quality.\nResponsibilities\nArchitect and own end-to-end test strategies for new features, developing scalable tests, frameworks, and tooling to ensure quality.\n\nLead contributions to industry-standard benchmarks and drive adoption of rigorous evaluation methodologies.\n\nDefine and drive automation initiatives to significantly improve internal engineering efficiency and test coverage.\n\nMake strategic decisions around coverage trade-offs, resource requirements, and risk-based testing priorities.\n\nServe as a technical anchor in a highly agile environment, adapting quickly to shifting priorities while maintaining quality standards.\n\nMentor and guide junior SDETs on testing methodology, debugging practices, and automation development.\n\nProactively identify systemic quality gaps and drive cross-functional initiatives to address them.\n\nLead and facilitate effective technical communication across teams and time zones.\n\nSkills & Qualifications\n5+ years of relevant industry experience in software integration, development, or quality engineering.\n\nDeep expertise in automation and programming using one or more languages such as Python, C++, or Go; ability to design and build reusable test frameworks from the ground up.\n\nProven experience testing compute, machine learning, networking, or storage systems within large-scale enterprise environments.\n\nStrong track record of debugging complex issues across distributed, scaled-out deployments.\n\nDemonstrated ability to lead cross-functional quality initiatives involving product development, product management, customer operations, and field teams.\n\nExcellent verbal and written communication skills, with experience presenting technical findings to both engineering and leadership audiences.\n\nStrong organizational skills, ownership mindset, and ability to drive projects to completion independently.\n\nExperience leading and mentoring engineers across geographically dispersed teams and time zones.\n\nPreferred Skills & Qualifications\nHands-on experience with ML workloads including LLM and/or multimodal training or inference.\n\nDeep familiarity with hardware architecture, performance optimizations, compilers, and ML frameworks.\n\nExperience designing test strategies for distributed systems, cloud infrastructure, and security validation.\n\nExperience with microservices deployment, debugging, and orchestration at scale.\n\nPrior experience owning or significantly contributing to a team's quality engineering culture or test infrastructure.\n\nLocation\nThis role follows a hybrid schedule, requiring in-office presence 3 days per week. Fully remote is not an option.\nOffice locations: Sunnyvale, CA | Toronto, Canada\nWhy Join Cerebras\nPeople who are serious about software make their own hardware.
