Systems SW Engineer

Cupertino, California, United States Hardware

The Hardware Test Engineering team develops world‑class electrical instruments that enable the design, validation, and manufacturing of Apple’s most advanced products. We are looking for a passionate Software/Firmware Engineer to design and build the embedded and application software that powers these instruments. You will work at the intersection of hardware, firmware, and software — creating solutions that deliver precise measurements, seamless integration, and exceptional user experience.

Develop custom software solutions across the full stack of our hardware test instruments and stations, from embedded firmware to APIs and user interfaces. Architect and implement frameworks, APIs, and control layers for instrument functionality. Design and code application‑specific firmware for precision measurement and signal generation for high speed I/O interfaces. Build automation scripts and data analysis tools to accelerate validation and production workflows.

Collaborate closely with product teams including EE, Signal Integrity, FPGA, and test engineering and logistics teams to define requirements, bring up new hardware, and validate system performance.

• BS/MS in Electrical Engineering, Computer Engineering, or related field
• 7+ years of experience in embedded software or firmware development for hardware systems or instruments
• Strong programming skills in C/C++ for embedded systems and Python or ObjC for test automation and application‑level development
• Ability to travel (domestic and international) up to 20%

• Experience developing firmware and device drivers for custom hardware platforms (STM
  32 preferred)
• Experience designing or integrating APIs and frameworks for instrument control and data acquisition
• Experience with scripting and automation frameworks for validation, manufacturing test, or lab instrumentation
• Hands‑on experience with communication protocols (SPI, I²C, UART, USB, Ethernet, PCIe, or high‑speed serial links)
• Hands‑on experience with SW debugging like GDB, and proficiency in the lab equipment used for debugging HW. e.g., multimeter, oscilloscope, logic analyzer, etc.
• Understanding of electrical engineering fundamentals (signal integrity, analog/digital interfaces, timing, and noise)
• Experience with high‑speed interfaces (USB, PCIe, Display Port, Thunderbolt etc.)
• Familiarity with CI/CD pipelines, version control, and modern software development workflows
