Job Description

L3Harris Space and Mission Systems seeks a Lead Embedded Software Engineer to develop Embedded Flight Software for space-based imaging payloads. The role requires strong technical depth in low-level embedded software, hardware interfacing, and multi-threaded application development, with the ability to provide technical leadership and mentorship to junior engineers.

Essential Functions

• Design, develop, test, and maintain embedded C++ software on Linux for space-based and mission-critical applications.
• Develop software that interfaces directly with hardware, including low-level I/O control, device communication, register-level interaction, and interrupt processing.
• Build and maintain multi-threaded applications with attention to determinism, synchronization, resource management, and system performance.
• Integrate and utilize foundational software frameworks such as NASA core Flight System (cFS) or comparable middleware and reusable flight software components.
• Support software architecture, implementation, debugging, and optimization throughout the software development lifecycle.
• Collaborate closely with systems, hardware, integration, and test teams to ensure software meets mission, interface, and performance requirements.
• Participate in software bring-up, hardware/software integration, troubleshooting, and verification activities in lab and system environments.
• Contribute to code reviews, technical planning, software standards, and development best practices to improve quality, maintainability, and compliance.
• Provide technical leadership, including guiding design decisions, reviewing junior engineers’ work, and mentoring entry-level staff in embedded software development methods and tooling.

Qualifications

• Bachelor’s degree in Computer Engineering, Computer Science, or related field and a minimum of 9 years of relevant experience; graduate degree with minimum 7 years of experience; or at least 13 years of experience in lieu of a degree.
• Ability to obtain TS/SCI security clearance.
• 7+ years experience in embedded software development, system design, debugging, and integration on aerospace products.
• 5+ years experience with RTOS (e.g., VxWorks, FreeRTOS, RTLinux, QNX) and programming languages such as C/C++, Python, and scripting.
• Professional experience with DevOps practices, Jenkins, and continuous integration tools.
• Experience working with Versal, MicroBlaze, bare metal development, and kernel/device drivers.
• Experience with embedded command and control for various applications, including mechanisms, serial communications, and distributed messaging.

Preferred Additional Skills

• Active Top Secret or TS/SCI clearance is highly preferred.
• Expertise in the full space-based systems lifecycle, including requirements flow-down, allocation, design, development, test, and sell-off.
• Knowledge of MBSE tools (e.g., Cameo) and wideband/narrowband telemetry and messaging.
• Experience in space payload systems and NASA Core Flight System/Core Flight Executive (cFS/CFE) or similar reusable software frameworks used in aerospace and spaceflight applications.
• Experience in Command & Control Software, Sensor Processing Systems, and Optical Systems/telescopes.
• Knowledge of microprocessor/microcontroller architecture and programming, and familiarity with FPGAs.
• Understanding of real-time and embedded Linux concepts, including inter-process communication, scheduling, and performance tuning.
• Experience estimating large software programs for new business opportunities.
• Proficiency in release engineering, change and configuration management, and continuous integration.
• Experience developing software for microcontrollers with interfaces such as I2C, SPI, UART, CAN.
• Develop, customize, and maintain Board Support Packages (BSP) for various hardware platforms.
• Integrate BSP components, including bootloaders, device drivers, and operating systems.
