As a Senior Embedded Software Engineer – Crypto, you will design, develop, and integrate advanced cryptographic embedded software solutions for satellite avionics and payload data processing systems. These solutions will include real-time system monitoring, Linux board support packages, and low-level interfaces for sensors, communication buses, radios, and COMSEC equipment. You will work closely with Systems, Hardware, and FPGA teams to deliver secure, rugged, and reliable Low-SWaP products. Your deep technical expertise and leadership will also support team-wide mentorship and guide secure software development best practices.

Design Embedded Crypto Solutions: Design and implement embedded software and cryptographic solutions for multi-core processors integrated with FPGAs (e.g., Xilinx, Microsemi, Microchip, Vorago).
Develop Secure Software Systems: Develop and maintain secure, real-time software in C/C++ and memory-managed languages for ARM Cortex and RISC-V architectures running embedded Linux and RTOS environments.
Integrate Hardware Interfaces & Protocols: Configure and support interconnects such as SPI, I2C, UART, GPIO, PCIe, Ethernet, and SpaceWire, while implementing secure networking protocols (e.g., IPsec, TLS) and cryptographic algorithms (e.g., AES, RSA, ECDSA).
Customize Linux Environments: Configure and customize Linux kernels, system settings, and bootloaders (U-Boot, GRUB), ensuring system performance and security for aerospace-grade deployments.
Translate Requirements into Architecture: Analyze complex customer and system requirements and translate them into robust, scalable, and secure embedded software designs and architectures.
Support Integration & Debugging: Lead efforts in integrating software with hardware platforms and conduct system-level debugging and validation to ensure functionality, reliability, and security.
Lead Technical Execution: Mentor and guide junior engineers through code walkthroughs, design reviews, and technical oversight, while contributing to reusable embedded software modules and secure software pipelines.
Ensure Compliance & Best Practices: Interpret and implement government and industry standards for cryptography and cybersecurity, and participate in continuous improvement efforts across workflows and development practices.

Bachelor’s Degree in a related field (Electrical or Computer Engineering, Computer Science).
9 or more years of experience developing secure cryptographic systems and software.
Proficiency in C/C++ for embedded systems and low-level driver development.
Advanced proficiency in memory-managed embedded languages (e.g., Rust, Go) for secure systems.
Deep experience with embedded Linux systems, kernel configuration, and bootloaders.
Strong understanding of RTOS-based development and real-time constraints.
Demonstrated experience interpreting schematics and hardware documentation for driver development.
Proficient in networking and communications protocols, including secure communication standards.
Familiarity with cryptographic principles and their application in embedded systems.
Experience with software integration, debugging, and system-level validation.
Excellent problem-solving, documentation, and technical communication skills.
Proven ability to mentor and support junior engineers in a collaborative environment.
Active U.S. Security Clearance required.

Familiarity with parallel-processing frameworks such as OpenCL or CUDA is a plus.

401(k) with 3% company match (automatic enrollment)
Comprehensive medical, dental, vision, HSA & life insurance
10 paid holidays + 120 hours PTO (starting in year one)
Access to ancillary benefits such as critical illness, accident, disability, legal and pet insurance.
Flexible Work-Life Balance: Enjoy a 9/80 work schedule with every other Friday off—whether you use it to recharge, work on a passion project, or spend time with family, the choice is yours.
Continuous Learning & Development: We’re serious about professional development. From tuition reimbursement to internal "Ask Me Anything" sessions and weekly “Lunch & Learns,” we make learning a core part of the job.
Mission-Driven Culture: We aren’t just building tech—we’re enabling the next era of space exploration. Our Culture Ambassadors help lead initiatives around inclusion, positivity, recognition, and transparency. Here, your voice is heard, your work is respected, and your individuality is celebrated.
