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 Preferred Qualifications * 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 Desired Characteristics & Attributes * 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, ATE Testers, Application Programming Interface (API), Artificial Intelligence (AI), Automation, Autonomous Driving Systems, Best Practices, C Programming Language, C++ Programming Language, Code Reviews, Coding Standards, Communication Skills, Communications Protocols, Computer Engineering, Computer Firmware, Computer Science, Continuous Deployment/Delivery, Continuous Integration, Debugging Skills, Debugging Tools, Device Drivers, E Programming Language, Electrical Engineering, Electronics, Embedded Software, Embedded Systems, Establish Priorities, FPGA, Genetics, Hal, Hardware Administration, Hardware Quality Assurance, Information/Data Security (InfoSec), Infrastructure Software, Integrated Circuits (ICs), Integration Testing, International Business, Internet of Things, Laboratory, MATLAB, Manufacturing, Manufacturing Debugging, Microcontroller, Microsoft C# (C Sharp), Multiplatform/Cross-Platform, Network Operations Center, Oscilloscope, Phase Noise Analysis, Production Systems, Prototyping, Python Programming/Scripting Language, Release Management/Engineering, Reliability Engineering, Reliability Testing, Research & Development (R&D), Semiconductors, Sockets, Software Design, Software Development, Software Engineering, Standards Development, Startup, Systems Engineering, Systems Maintenance, Technical Writing, Telemetry, Test Automation, Test Bench, Test Equipment, Test Plan/Schedule, Testing, Unit Test, Universal Asynchronous Receiver-Transmitter (UART), Validation Testing, Wearables, Willing to Travel, YouTube ## Description SiTime is looking for a talented and motivated Senior Software/Firmware Engineer to join our growing infrastructure team in Michigan. You will build and scale next-generation mixed-signal semiconductor test systems and automation platforms, collaborating closely with hardware, validation, and test engineers across global teams. This role is essential to ensuring the performance, stability, and scalability of production and R&D test infrastructure This position is "startup mode" by design: you'll be hands-on, move fast, own outcomes end-to-end, and help shape the architecture, coding standards, and development workflows as the team scales Responsibilities * 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 ## Related Videos - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Android beyond mobile: Cars, TVs, and Wearables](https://www.wearedevelopers.com/videos/553-android-beyond-mobile-cars-tvs-and-wearables) - [Software stack under and over the hood of the fastest accelerating car in the world](https://www.wearedevelopers.com/videos/221-software-stack-under-and-over-the-hood-of-the-fastest-accelerating-car-in-the-world) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [Now is the time for industrialized software development](https://www.wearedevelopers.com/magazine/601-now-is-the-time-for-industrialized-software-development) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers)
