The Opportunity:CACI is seeking a senior staff-level embedded software engineer with deep electrical engineering and computer science experience to lead the architecture, development, and delivery of embedded systems for RF communications. This role is ideal for an engineer who thrives in low-level, performance-critical environments, can drive design decisions, and enjoys mentoring others while setting technical direction for the platform.
This position is located on-site at our Colorado Springs, CO office.
Responsibilities:
Lead the architecture and implementation of embedded software to deliver robust, consistent performance while meeting interface and radiation constraints.
Support board bring-up and low-level driver development; integrate with FPGA logic and DSP blocks.
Design, configure, and optimize embedded Linux solutions.
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 boot, cryptographic key management, and secure, robust firmware update mechanisms; drive compliance with relevant security guidelines.
Establish and/or contribute to continuous integration/continuous deployment (CI/CD) for embedded targets, and support static analysis and unit/integration testing.
Mentor and elevate the team: perform design reviews, code reviews, and technical coaching; author clear architecture and design documentation.
Collaborate cross-functionally with program management and customers to define milestones, de-risk schedules, and deliver production-quality software for mission operations.
Qualifications:Required:
Bachelor's in Electrical Engineering or Computer Science (or related field), with 8+ years in embedded software.
Proficiency in C/C++ for embedded targets.
Strong systems fundamentals (e.g., memory models, concurrency, synchronization, interrupts, cache/NUMA effects, DMA).
Strong experience with an RTOS and/or embedded Linux on ARM and SoC platforms; comfortable with bootloaders, device trees, BSPs, and kernel/driver development.
Understanding of common embedded protocols (e.g., SPI, I2C, UART, RS-422, PCIe, AXI, Ethernet, GPIO, DMA).
Experience with PCB designs and 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.
Familiarity with agile development using Atlassian tools.
Strong documentation habits and contributions to ICDs and design artifacts.
Desired:
Master's degree in Electrical Engineering or Computer Science (or related field), with 10+ years in embedded software.
- Exposure to satellite communications systems; familiarity with CCSDS and space-communications standards and constraints.
Practical RF lab skills, including the use of spectrum analyzers, VNAs, oscilloscopes, logic analyzers, and RF test fixtures.
Knowledge of software-defined radio (SDR) technologies.
Experience with the Rust language, Python, and the Protocol Buffers (Protobuf) IDL and tooling.
Hands-on integration with FPGAs; familiarity with Xilinx/AMD toolchains.
Secure boot, TPM, and cryptographic techniques.
Experience designing for reliability in radiation environments.
Track record of technical leadership: setting architecture, reviewing designs, mentoring engineers, and driving high-quality execution.
