Description 

We are seeking a motivated Firmware Engineer to join our engineering team. This role focuses on the development, testing, and maintenance of embedded software for cutting-edge analytical instrumentation in the spectroscopy field. The ideal candidate has a solid foundation in embedded systems, enjoys working close to hardware, and is eager to grow technical depth while solving real-world problems. 

Key Responsibilities 

• Perform all phases of embedded software development, including design, implementation, testing, integration, and maintenance for scientific instruments 

• Develop reliable firmware in C for ARM microprocessors and TI DSPs used in FTIR, Raman, and microscopy instruments 

• Design and implement programmable logic using VHDL for FPGAs and CPLDs 

• Develop manufacturing and support utilities using C#/.NET 

• Ensure timely delivery of high-quality products by working closely with project teams, SQA, and cross-functional engineering groups 

• Participate in design and architecture reviews 

• Develop and maintain technical documentation, including specifications, test plans, and user documentation 

Requirements 

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field. MS preferred.

• 2–4 years of hands-on experience in embedded software or firmware development. 

• Strong programming skills in C; experience with C++ is a plus. 

• Experience developing embedded software across the full lifecycle, including design, implementation, testing, integration, and maintenance. 

• Proficiency working with microcontrollers and embedded systems, including ARM-based processors and/or DSPs. 

• Strong understanding of low-level embedded concepts (e.g., interrupts, DMA, memory management) and ability to interpret hardware schematics. 

• Experience developing firmware for scientific or instrumentation-based systems is preferred. 

• Familiarity with real-time operating systems (RTOS) and/or bare-metal embedded systems. 

• Experience with programmable logic design (e.g., VHDL for FPGAs or CPLDs); experience debugging FPGA-based implementations is a plus. 

• Knowledge of common communication interfaces such as SPI, I2C, UART, Ethernet, and USB. 

• Experience with debugging tools such as JTAG debuggers, oscilloscopes, logic analyzers, and protocol analyzers. 

• Familiarity with version control systems (e.g., Git) and modern development workflows (e.g., CI/CD). 

• Exposure to embedded Linux or higher-level system integration is a plus. 

• Experience developing utilities or applications using C#/.NET is a plus. 

• Understanding of low-level system components such as bootloaders, device drivers, and power management is desirable. 

• Ability to contribute to embedded software architecture and communication protocol design. 

• Experience with data acquisition, signal processing, or motor control systems is a plus. 

• Exposure to AI/ML tools used to support embedded systems development (e.g., code generation, debugging, test automation, or data analysis). 

• Awareness of how AI/ML techniques may be applied to instrument data processing, signal analysis, or system optimization. 

• Demonstrated ability to collaborate effectively with cross-functional teams, including hardware, systems, and quality engineering. 

• Strong problem-solving skills, attention to detail, and ability to debug complex system-level issues. 

• Experience working in regulated development environments (e.g., medical devices, automotive, aerospace) is a plus. 

• Effective written and verbal communication skills, including the ability to contribute to technical documentation and design reviews. 

• Ability to manage individual tasks with moderate guidance while contributing to team deliverables. 

• Willingness to learn new technologies and take on evolving technical challenges.
