Firmware Engineer

About This Role

This engineering job focuses on building embedded systems that directly interact with hardware, primarily through low-level, real-time, device-facing firmware. The role involves some supporting PC software work for diagnostic and customer-facing tools. You will be deeply involved with hardware, including bringing up new boards, writing drivers, debugging with JTAG and oscilloscopes, and creating robust firmware for production and reliable field performance.

Responsibilities

• Design, implement, and maintain embedded firmware for ARM-based microcontrollers
• Own features and systems from concept through production release
• Develop device drivers and low-level hardware interfaces
• Build robust firmware architectures (state machines, fault handling, watchdogs, diagnostics, recovery)
• Work in RTOS-based systems with real-time constraints (timing, determinism, DMA, interrupts)
• Support hardware bring-up, including schematic-driven debugging and early prototype validation
• Interface with peripherals including ADCs, DACs, sensors, and communication interfaces
• Debug firmware and hardware issues using JTAG/SWD, oscilloscopes, and logic analyzers
• Develop Windows desktop applications (WinForms/WPF) for diagnostics, calibration, and customer tools
• Build and maintain test systems (unit, integration, regression, hardware-in-the-loop)
• Support production release, including field issue investigation and root cause analysis
• Contribute to CI/CD pipelines, automated builds, and release processes

Requirements

• 7–15 years of embedded firmware experience in hardware-based products
• Strong proficiency in C/C++
• Experience with ARM-based microcontrollers (including Microchip SAM7 or similar)
• Proven experience writing device drivers and working directly with hardware
• RTOS experience (task scheduling, synchronization, interrupts, timing)
• Strong firmware design skills (state machines, error handling, diagnostics, recovery strategies)
• Demonstrated ability to work independently from concept through production-ready implementation
• Hands-on debugging using JTAG/SWD, oscilloscope, and logic analyzer
• Experience with communication protocols: I2C, SPI, USB, UART, RS-232, RS-485
• Experience with DMA and real-time data handling
• Experience using Git or similar version control systems
• Experience developing Windows desktop applications (C#, WinForms or WPF)
• Ability to read schematics and understand electronics fundamentals (ADC, DAC, amplifiers, sensors)
• Experience supporting products in a production environment (ISO 9001 or similar)
