Job summary

Cerebras Systems in Sunnyvale, CA, is hiring a Software Engineer to design and build the core software behind Cerebras engineering infrastructure. You will work on Python frameworks, orchestration systems, distributed execution, scheduling, test infrastructure, and developer tooling, defining architecture and APIs used daily by engineering teams.

The role suits engineers who enjoy reading unfamiliar code, debugging hard problems, and improving designs rather than applying quick fixes; strong

Qualifications

• 3+ years of professional software‑engineering experience.
• Strong proficiency in Python and understanding of runtime behavior.
• Experience designing maintainable software systems, libraries, frameworks, backend services, or developer‑facing APIs.
• Good judgment around software architecture, abstraction boundaries, design patterns, extensibility, and long‑term maintainability.
• Understanding of concurrency concepts such as processes, threads, asynchronous execution, synchronization, and shared state.
• Foundational understanding of operating systems, including processes, signals, filesystems, resource management, and program execution.
• Foundational understanding of distributed‑systems concepts such as retries, timeouts, idempotency, partial failure, coordination, and eventual consistency.
• Strong debugging and problem‑solving skills, including the ability to form hypotheses, gather evidence, and work through unfamiliar systems independently.

Responsibilities

• Design, develop, test, and maintain Python frameworks and services used to orchestrate engineering workflows across machines and clusters.
• Build reusable abstractions for scheduling, distributed execution, resource management, test execution, workflow planning, and failure recovery.
• Define clear APIs, module boundaries, extension points, and data models that allow infrastructure systems to evolve without becoming difficult to maintain.
• Reason about concurrency, asynchronous execution, multiprocessing, state management, retries, idempotency, cancellation, and partial failures.
• Debug complex issues spanning Python applications, operating systems, processes, filesystems, networking, remote machines, and distributed services.
• Write high‑quality automated tests and documentation for infrastructure that is expected to be reliable and widely reused.
• Partner with platform, CI, release, quality, ML systems, and product engineering teams to understand requirements and translate them into scalable software designs.
