Join our small, agile, and mission-driven team where your work has real impact and your growth has no limits. We’re not just reaching for the stars—we’re engineering them. Let’s innovate the infinite, together.

A DAY IN THE LIFE:

The Embedded Software Engineer III plays a key role in developing software solutions for satellite avionics and payload data processing systems. This position involves creating real-time system monitoring and power management software, preparing Linux board support packages for customer flight applications, and working with a variety of embedded systems, sensors, communication buses, radios, and communications security (COMSEC) equipment. Close collaboration with hardware and FPGA engineers is essential to deliver rugged, reliable, and integrated Low-Size, Weight, and Power (Low-SWaP) products to aerospace customers.

WHAT YOU'LL DO:

• Develop Embedded Software Systems: Design and implement embedded C/C++ software for multi-core processors and FPGA-integrated systems (Xilinx, Microchip, Vorago), targeting ARM Cortex and RISC-V architectures.


• Build and Customize Linux Platforms: Configure Linux systems including kernel and bootloader (U-Boot, GRUB) modifications to support flight applications and mission requirements.


• Implement Secure Communications: Develop networking and cryptographic functionality (e.g., IP, TLS, IPsec, AES, RSA, ECDSA) and interface with buses and protocols like SPI, I2C, UART, PCIe, SpaceWire, and Ethernet.


• Drive End-to-End Development: Translate customer and system-level requirements into robust software solutions, participating in design, documentation, integration, validation, and testing.


• Collaborate and Present: Work closely with cross-functional teams, support system integration, debug software/hardware issues, and present technical updates to both internal and external stakeholders.


• Manage Development Lifecycle: Track features, bugs, and build processes using industry-standard tools for version control and release management.

YOU’RE AWESOME AT:

• Embedded Software Development: Expertise in embedded software design and implementation, particularly within aerospace applications.


• Complex Document Analysis: Ability to read, interpret, and analyze complex technical documents and specifications.


• Cybersecurity and Encryption: Familiarity with writing embedded C code that incorporates cybersecurity and encryption measures to ensure secure communications.

WHAT YOU’LL NEED:

• Bachelor’s Degree in Electrical or Computer Engineering, Computer Science, or related field.


• 5 or moreyears of professional experience developing embedded software in C/C++ for Linux and/or RTOS-based systems.


• Deep knowledge of embedded platforms, multi-core processors, and interfacing standards (SPI, I2C, UART, PCIe, etc.).


• Experience configuring bootloaders (U-Boot, GRUB) and customizing Linux kernels for application-specific needs.


• Proficient with networking protocols (IP, TLS, IPsec) and cryptographic systems (AES, RSA, ECDSA, ECDH).


• Familiarity with version control and task tracking systems (e.g., Git, Jira) and modern software development workflows.


• Strong technical communication skills and ability to present designs and progress to both engineers and stakeholders.


• Experience with OpenCL, CUDA, or other parallel-processing frameworks is a plus.


• Prior work with aerospace or defense systems and knowledge of COMSEC requirements highly desirable.


• Ability to obtain a U.S. Security Clearance.
