The Opportunity:

CACI is seeking an Embedded Software Engineer to build software for our space-based RF communications platforms. You'll develop low-level, performance-critical code across embedded Linux and bare-metal targets. You'll partner with RF, FPGA, and systems teams from board bring-up through delivery. This role is ideal for an engineer who enjoys working close to the hardware and wants to take on more design ownership. This position is on-site in Colorado Springs, CO.

Responsibilities:

· Implementation of embedded software to deliver robust, consistent performance while meeting design constraints; Contribute to architecture and design decisions.

· Build and extend embedded Linux service and kernel components.

· Support and improve bare-metal/C embedded applications.

· Support board bring-up and low-level driver development; integrate with FPGA logic and DSP blocks.

· Collaborate with RF and systems teams on radio architectures; contribute to interface control documents (ICDs) and system requirements.

· Design for reliability, resiliency, and safety in space environments.

· Engineer secure, robust firmware update mechanisms.

· Establish and/or contribute to continuous integration/continuous deployment (CI/CD) for embedded targets, and support static analysis and unit/integration testing.

· Participate in system design, hardware interface reviews and code reviews.

· Collaborate cross-functionally with program management and customers to refine requirements, build schedules, and deliver production-quality software for mission operations.

Qualifications:

Required:

· Bachelor’s degree in Electrical Engineering or Computer Science (or related field), with 3+ years in embedded software.

· Proficiency in C/C++ for embedded targets.

· Strong systems fundamentals: Linux, networking, memory management, concurrency, hardware abstraction.

· Experience with Yocto or other embedded Linux. Comfortable with kernel module development.

· Understanding of common embedded protocols (GPIO, SPI, I2C, UART, RS-422).
