Summer Embedded Firmware Engineer Jobs in Ohio (NOW HIRING)

How you will make an impact 

At Thermo Fisher Scientific, our mission is to enable our customers to make the world safer. As an Embedded Firmware Engineer, you will help develop and deliver the embedded software that powers next-generation handheld radiation detection and identification systems used in public safety, dosimetry, environmental monitoring, and emergency response. 

You will play a key role in translating advanced sensing technologies and system concepts into reliable, field-ready products by designing, developing, and integrating robust firmware for embedded platforms. Working closely with radiation scientists, electrical engineers, systems engineers, and software teams, you will help ensure our instruments perform accurately and reliably in demanding real-world environments. 

This role is well suited for an early-career engineer with strong embedded software fundamentals and hands-on exposure to radiation detection, spectroscopy, scientific instrumentation, or sensor signal processing through graduate research, internships, co-ops, or prior employment. 

Position Summary 

We are seeking an Embedded Firmware Engineer to design, develop, test, and maintain firmware for next-generation radiation detection products. The role requires strong embedded C/C++ skills, microcontroller-based development, and familiarity with real-time systems and hardware interfaces. The ideal candidate is comfortable working close to the hardware and has enough radiation-detection or signal-processing background to understand detector data, calibration, and measurement behavior. Experience with Renesas platforms is a plus, but not required. 

Experience with radiation instrumentation, spectroscopy, detector signal processing, Python-based analysis, or connected embedded products is a strong plus. 

Key Responsibilities 

• Design, develop, debug, and maintain embedded firmware using C/C++ for microcontroller-based radiation detection systems. 

• Develop firmware running on real-time operating systems, including task scheduling, inter-task communication, timing, synchronization, and resource management. 

• Bring up and integrate firmware on microcontroller-based platforms, including peripheral configuration, board support packages, bootloaders, and device drivers; experience with Renesas platforms is a plus. 

• Work closely with electrical engineering and radiation science teams to support hardware bring-up, detector/electronics integration, board validation, and root-cause analysis. 

• Develop and maintain low-level drivers for interfaces such as I2C, SPI, UART, USB, CAN, Ethernet, GPIO, ADC, PWM, and similar embedded peripherals. 

• Support implementation and integration of radiation measurement functions such as detector calibration, pulse/event processing, spectral data handling, count-rate processing, alarm logic, and detector health/status monitoring. 

• Analyze detector data, spectra, and acquired signals with scientists and systems engineers to troubleshoot instrument performance and translate validated algorithms or calibration methods into efficient embedded implementations. 

• Develop or use Python, MATLAB, or similar analysis tools for firmware verification, detector characterization, calibration studies, and test automation. 

• Participate in firmware architecture, design reviews, code reviews, and technical decision-making. 

• Implement robust, maintainable, and testable firmware for commercial radiation detection and industrial embedded products. 

• Debug complex firmware and hardware interactions using oscilloscopes, logic analyzers, JTAG/SWD debuggers, and other lab equipment. 

• Support integration of embedded systems with higher-level software, detector-processing functions, connectivity stacks, and cloud-based services. 

• Develop unit, integration, and system-level test strategies for embedded firmware. 

• Create and maintain technical documentation, including requirements, design specifications, test plans, and release notes. 

• Collaborate with cross-functional teams to deliver high-quality products on schedule. 

Required Qualifications

• Ability to read schematics and work closely with hardware engineers during board bring-up and troubleshooting. 

• Strong analytical, debugging, and problem-solving skills, with excellent written and verbal communication skills. 

Preferred Qualifications 

• Master’s degree or experience involving embedded systems, radiation detection, spectroscopy, nuclear instrumentation, signal processing, or sensor electronics. 

• Experience developing firmware for an RTOS such as FreeRTOS, ThreadX, Zephyr, embOS, or similar. 

• Experience with Renesas RA, RX, RL78, RZ, or other commercial microcontroller platforms and associated SDKs, BSPs, or IDEs. 

• Familiarity with radiation detector technologies such as scintillators/SiPMs, semiconductor detectors, gamma-ray spectroscopy, neutron detection, or dosimetry. 

• Experience with detector calibration, digital pulse processing, spectral analysis, count-rate processing, neutron/gamma discrimination, or related radiation measurement algorithms.
