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.

• 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.

• 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).
• Practical lab skills, including the use of oscilloscopes, and logic analyzers.
• Comfortable understanding PCB designs and participating in schematic reviews.
• Ability to collaborate closely with RF, FPGA, systems, and test teams.
• Experience debugging mixed HW/SW issues.
• Ability to work on multiple efforts concurrently.
• Strong documentation habits.

• Master’s degree in Electrical Engineering or Computer Science
• Hands-on integration with FPGAs; familiarity with Xilinx/AMD tool chains.
• Strong experience with embedded Linux including boot loader, device tree, and kernel/driver development.
• Secure boot, TPM, and cryptographic techniques.
• Experience using high-speed data in embedded systems (PCIe, AXI, FPGA Serdes).
• Practical RF lab skills, including the use of spectrum analyzers, and RF test fixtures.
• Knowledge of software-defined radio (SDR) technologies.
• Exposure to satellite communications systems; familiarity with CCSDS and space-communications standards and constraints.
• Experience designing for reliability in radiation environments.
• Experience with the Rust language and Protobuf.
• Familiarity with agile development using Atlassian tools.

At CACI, we place character and innovation at the center of everything we do. As a valued team member, you’ll be part of a high-performing group dedicated to our customer’s missions and driven by a higher purpose – to ensure the safety of our nation.
