Responsibilities:

• We design, develop, release, and support the embedded firmware and Windows desktop software that power our surface profiler, thin film, sheet resistance, and nanoindentation measurement instruments.
• We deliver well-defined features and components with high-level guidance, including estimating work, communicating risks and tradeoffs, and delivering on schedule.
• We collaborate cross-functionally across the development lifecycle to define architecture and create system- and subsystem-level requirements and specifications.
• We design, implement, and debug embedded firmware in C/C++ for microcontrollers and real-time control of instrument hardware.
• We work with communication interfaces such as USB, Ethernet, serial/UART, SPI, and I2C.
• We develop Windows desktop software in C#/.NET (WPF/WinForms) and C++ for instrument control, GUI, and data analysis.
• We write maintainable, multithreaded code and use AI-assisted tools responsibly under company security policies.
• We partner with electrical and hardware engineers on board bring-up, signal and schematic debugging, and firmware/hardware co-development using oscilloscopes, logic analyzers, and in-circuit debuggers.
• We build robust unit and integration tests and use profiling to improve performance, memory usage, reliability, and security.
• We participate in design reviews and incorporate feedback from stakeholders and subject matter experts.
• We troubleshoot system and subsystem issues using logs and experiments, contribute to root-cause analysis, implement fixes with guidance, and help prevent recurrence.
• We independently learn and apply new software technologies.
• Occasional travel may be required to our headquarters, customer sites, or other business locations, and travel is expected to be less than 10% of working time.
