Staff Embedded Software Developer

Fluke Calibration designs and builds industry‑leading calibration instruments used by metrology labs and industrial customers worldwide. Our products rely on exceptionally precise hardware, advanced measurement science, and world‑class embedded software. As part of the Fluke Calibration engineering team, you will directly influence the accuracy, reliability, and performance of the tools that underpin global measurement standards. 

The Staff Embedded Software Developer is a senior technical contributor to the Fluke Calibration organization. This role carries end‑to‑end responsibility for designing, implementing, and sustaining embedded software across multiple execution environments, including embedded Linux, POSIX‑based OS environments (e.g., Zephyr), real‑time kernels (e.g., FreeRTOS), and bare‑metal platforms used in precision calibrators. 

In this role, the engineer will ensure that embedded software applications integrate seamlessly with precision analog/digital circuitry, hardware control loops, measurement systems, and calibration‑grade architectures. They will collaborate closely with the Platform Architecture Team to evolve OS support, system abstractions, and core platform services while ensuring that design choices are robust, maintainable, and aligned with Fluke Calibration’s long‑term technical roadmap. 

Key Responsibilities: 

• Embedded Software Development & Ownership  

• Own the design, implementation, testing, documentation, and deployment of embedded software for calibration instruments. 

• Develop effective, efficient, and reliable embedded software throughout all project phases: concept, architecture, implementation, verification, release, and sustaining. 

• Continuously enhance and modernize the embedded software platform to meet evolving customer needs and maintain a robust development environment. 

• Precision Hardware & Control Systems 

• Design and debug hardware control loops, including PID, servo, stimulus generation, voltage/current regulation, stability control, and deterministic timing sequences. 

• Work directly with electrical engineers and the calibration hardware team to ensure software integrates seamlessly with precision analog/mixed‑signal circuits, ADC/DAC chains, thermal control elements, and low‑noise measurement systems. 

• Tune and optimize real‑time system behavior to achieve metrology‑grade stability, repeatability, and traceability. 

• System Debugging & HW/SW Integration 

• Diagnose complex issues across the full stack: interrupts, drivers, peripherals, concurrency, caches, memory protection, and timing anomalies. 

• Use oscilloscopes, logic analyzers, JTAG/SWD, protocol analyzers, and signal generators to debug hardware interactions. 

• Collaborate with validation, systems engineering, and manufacturing test teams to ensure stable, compliant, and verifiable system behavior. 

• Cross‑Functional Leadership 

• Provide technical leadership to junior engineers through mentorship, architecture reviews, and design guidance. 

• Influence product direction by identifying risks, proposing architectural improvements, and contributing to technology roadmaps. 

• Communicate effectively across software, hardware, verification, manufacturing, and quality teams. 

Key Qualifications: 

• Bachelor's degree in computer science, computer engineering, electrical engineering, or closely related fields. 

• 10+ years of experience developing embedded firmware/software in environments such as:  

• Embedded Linux, POSIX‑based RTOS (Zephyr, QNX, etc.) 

• Real‑time schedulers (FreeRTOS or equivalent) 

• Bare‑metal systems for MCUs 

• Strong proficiency in C/C++, embedded toolchains, cross‑compilers, GCC/Clang, Make/CMake, and modern build systems. 

Experience with:  

• Hardware control loops and real‑time signal processing 

• ADC/DAC subsystems, sensor interfaces, timing‑critical routines 

• Device drivers, interrupts, concurrency, memory models, and OS fundamentals 

• Networking and connectivity stacks (TCP/IP, USB, GPIB) 

• Proven ability to work at OS, driver, and low‑level hardware layers. 

• Strong debugging skills using embedded instrumentation tools.
