Principal Engineer

Exodigo is the leading underground mapping solution for non-intrusive discovery. Our platforms combine multi-sensor fusion, 3D imaging, and AI technologies to create complete, accurate underground maps that enable confident decision-making for customers across the built world. We transform the project lifecycle for our customers, who include key community stakeholders in the utilities, transportation and government sectors.

We are experiencing sky-rocketing growth and closed a historically large $96M Series B round in July of 2025.

Job description:

We are seeking a highly skilled Principal Engineer to join our team and play a pivotal role in designing, developing, and implementing cutting-edge solutions. This role requires deep expertise in both high-level software architecture and low-level embedded systems development, with a strong focus on security and cryptography.

The ideal candidate is a versatile, self-sufficient problem-solver capable of contributing to all phases of the software development lifecycle, from initial design and architecture to implementation, testing, and deployment. This role will involve working with a variety of target environments, including resource-constrained microcontrollers (MCUs) and embedded Linux systems, and will include responsibilities related to positioning systems and data acquisition.

Key Responsibilities

• Design and implement robust, scalable, and secure full-stack solutions, spanning embedded systems, cloud systems, Linux, Windows, and other platforms.
• Develop and maintain low-level software components, including device drivers, firmware, and system integrations.
• Implement and integrate security measures, including cryptographic algorithms, secure communication protocols, and vulnerability mitigation strategies.
• Contribute to the architecture and design of complex systems, ensuring performance, reliability, and security.
• Write clean, efficient, and well-documented code in C, Python, and shell scripting.
• Participate in code reviews and contribute to development process improvements.
• Collaborate with hardware engineers, product managers, and cross-functional teams to develop high-quality solutions.
• Manage complexity and adhere to project timelines while working on large-scale projects.
• Stay up-to-date with the latest technologies and trends in embedded systems, security, and software development.
• Develop and debug software for resource-constrained microcontroller (MCU) environments, optimizing for performance and power consumption.
• Build and customize embedded Linux systems, including distributions like Ubuntu and Yocto Project.
• Design and implement data acquisition systems, including interfacing with sensors, actuators, and other hardware components.
• Integrate and utilize positioning systems (e.g., GPS, GNSS, IMUs) to provide location and navigation capabilities.
  
  

• 10+ years of experience in full-stack software development, with a strong focus on embedded systems and security.
• Bachelor's or master's degree, in Computer Science, Software Engineering, or a related field or equivalent.
• Deep understanding of operating systems internals (Linux, Windows).
• Proven experience in low-level development, including driver development, firmware programming, and hardware integration.
• Strong expertise in security and cryptography, including cryptographic algorithms, secure communication protocols, and security best practices.
• Proficiency in C, Python, and shell scripting.
• Experience in system integration and working on large, complex projects.
• Experience developing microcontroller (MCU) architectures (e.g., ARM Cortex-M series).
• Experience with embedded Linux build systems and toolchains (e.g., Yocto Project, Buildroot, Make, CMake, Autotools).
• Experience with data acquisition systems and related hardware interfaces (e.g., SPI, I2C, UART, ADC).
• Expertise in positioning systems (e.g., GPS, GNSS, IMUs, sensor fusion).
