SiTime Corporation Jobs Hiring Now

• Design and develop software/firmware for mixed-signal chip test systems and infrastructure platforms
• Build a robust Hardware Abstraction Layer (HAL) to standardize control of instruments, fixtures, and embedded controllers across multiple test platforms
• Architect modular, reusable software components (drivers, services, libraries, APIs) to enable rapid bring-up of new boards, sockets, and test capabilities
• Collaborate with hardware and test engineers to bring up systems, debug issues, and validate test setups (hands-on lab work expected)
• Partner with production teams to transfer test systems to OSAT and support ramp/debug in manufacturing environments
• Optimize and expand existing test automation frameworks for throughput, reliability, maintainability, and observability
• Define and implement software quality practices: code reviews, automated testing, release tagging, and CI/CD improvements for infrastructure software
• Document code, workflows, architecture decisions, and best practices for cross-team collaboration and long-term maintainability
• Operate effectively in a fast-moving environment: prioritize, scope, prototype, iterate, and harden solutions into production-grade systems

• 5+ years of hands-on experience in software and/or firmware development with demonstrated ownership of shipped, maintained systems
• Strong proficiency in Python, C/C++, C# (MATLAB experience is a plus)
• Proven experience building hardware-interfacing software such as device drivers, control software, embedded services, or instrument automation
• Experience with MCU and/or FPGA integration and control (bring-up, interfaces, command/control, validation)
• Familiarity with instrument communication protocols such as SCPI, VISA, serial/UART (and debugging these interfaces in real systems)
• Strong debugging skills spanning software + hardware boundaries (signal/logic-level thinking, structured root cause, reproducible fixes)
• Ability to work independently and collaboratively in a fast-paced environment; comfortable with ambiguity and rapid iteration
• Willingness to participate in overseas business travel (~1 month per year)
• MS in Computer Engineering, Computer Science, Electrical Engineering, or equivalent practical experience

• Experience designing and maintaining a HAL and modular architecture that supports multiple hardware variants and product lines
• Familiar with lab instruments such as oscilloscopes, digital multimeters, spectrum/phase noise analyzers, power supplies, and switching matrices
• Experience with bench, Automated Test Equipment (ATE), rack-level test infrastructure development (PXI, DAQ, switching/relay systems)
• Experience in mixed-signal IC validation/testing, characterization
• Strong software engineering fundamentals: interfaces, versioning, performance profiling, automated unit/integration testing
• Experience with CI/CD pipelines, packaging/release management, and runtime telemetry/monitoring for test infrastructure reliability
• Understanding of semiconductor test engineering and production workflow, including transfer-to-manufacturing and sustaining support

• High ownership mindset: delivers results, unblocks self and others, and drives issues to closure
• “Builder” mentality: enjoys hands-on work, prototypes quickly, then hardens solutions into maintainable platforms
• Strong communication: clear status, crisp technical writing, and effective collaboration across global teams
