Ingeniero Senior de Firmware

Job Description

We are seeking a highly technical Senior Firmware Engineer with 10+ years of dedicated microcontroller experience. Please note: This role is strictly focused on resource-constrained microcontrollers (bare-metal and RTOS environments). Candidates whose primary background is in application-level software, embedded Linux, or microprocessor systems will not be a fit for this position.

You will join an established, highly capable team of senior firmware engineers to architect, develop, and maintain critical low-level device interactions, bridging the gap between hardware functionality and system logic.

Responsibilities

• Architect and develop production firmware exclusively for resource-constrained microcontrollers (e.g., ESP32, TI C2000, ARM Cortex-M, or similar platforms) in bare-metal and RTOS environments.
• Write, optimize, and maintain efficient low-level code in C.
• Develop and configure low-level peripheral drivers and communication interfaces (UART, SPI, I2C, PWM, etc.).
• Perform deep hardware-level debugging to resolve complex hardware/software integration issues, including tracking down stack overflows, memory leaks, and tight timing constraints using oscilloscopes and logic analyzers.
• Collaborate directly with hardware engineers to define system interfaces and pinouts early in the design lifecycle.
• Automate and maintain local development environments and CI/CD pipelines (utilizing tools like Jenkins, Docker and Bitbucket).

Requirements

• Bachelor's or Master's degree in Electrical/Electronics Engineering, Computer Engineering, or Computer Science.
• 10+ years of professional experience strictly focused on microcontroller-based firmware development, distinctly separate from high-level microprocessor or OS-based development.
• Deep proficiency in C for embedded systems and extensive hands-on experience with Real-Time Operating Systems (e.g., FreeRTOS, ESP-IDF).
• Proven ability to work intimately with hardware schemas, read datasheets, and write firmware that interacts directly with registers and MCU peripherals.
• Extensive experience debugging complex embedded systems using hardware tools (JTAG, SWD, logic analyzers).
• Familiarity with software configuration management tools, version control systems, and automated build processes.
• Excellent communication skills with a track record of thriving in a collaborative, senior-level engineering environment.

Desired Qualifications

• Knowledge of power electronics, power inverters, or complex control algorithms.
• Familiarity with cellular modems, Bluetooth, Wi-Fi, and IoT protocols.
• Familiarity with functional safety standards (ISO 26262) and safety-critical software development.
• Familiarity with Agile or Scrum software development methodologies.

Benefits

Salary and Benefits: We offer a competitive salary and performance-based bonus program, top-tier benefits package, including medical, dental, and vision insurance, 401(k), and paid time off.
