Proficiency in release engineering, change and configuration management, and continuous integration.
Experience in developing software for microcontrollers with interfaces (e.g., I2C, SPI, UART, CAN).
Develop, customize, and maintain Board Support Packages (BSP) for various hardware platforms.
Integrate BSP components, including bootloaders, device drivers, and operating systems.

Responsibilities

Design, develop, test, and maintain embedded C++ software on the Linux operating system for space-based and mission-critical applications.
Develop software that interfaces directly with hardware, including low-level I/O control, device communication, register-level interaction, and interrupt processing.
Build and maintain multi-threaded applications with attention to determinism, synchronization, resource management, and system performance.
Integrate and utilize targeted foundational software frameworks for space applications, such as NASA core Flight System (cFS) or comparable middleware and reusable flight software components.
Support software architecture, implementation, debugging, and optimization across the full software development lifecycle.
Collaborate closely with systems, hardware, integration, and test teams to ensure software meets mission, interface, and performance requirements.
Participate in software bring-up, hardware/software integration, troubleshooting, and verification activities in lab and system environments.
Contribute to code reviews, technical planning, software standards, and development best practices to improve quality, maintainability, and compliance.
Provide technical leadership, including guiding design decisions, reviewing junior engineers’ work products, and mentoring entry-level staff in embedded software development methods and tools.
