Job Description:

L3Harris Space and Mission Systems is seeking a Lead Embedded Software Engineer for our Wilmington, MA location to join a team of experts developing Embedded Flight Software for space-based imaging payloads. This role requires strong technical depth in low-level embedded software, hardware interfacing, and multi-threaded application development, along with the ability to provide technical leadership and mentorship to junior engineers. The ideal candidate will have experience developing reliable software for mission-critical aerospace or space systems and familiarity with foundational frameworks such as NASA cFS or similar spaceflight software architectures.

Essential Functions:

• Design, develop, test, and maintain embedded C++ software on the Linux operating system 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 targeted foundational software frameworks for space applications, such as NASA core Flight System (cFS) or comparable middleware and reusable flight software components.
• Support software architecture, implementation, debugging, and optimization across the full 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 products, and mentoring entry-level staff in embedded software development methods and tools.

Qualifications:

• Bachelor’s Degree in Computer Engineering, Computer Science, or related field and minimum 9 years of prior relevant experience. Graduate Degree and a minimum of 7 years of prior related experience. In lieu of a degree, minimum of 13 years of prior related experience.
• Ability to obtain a 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 (C/C++, Python, scripting).
• Professional experience with DevOps practices, Jenkins, and continuous integration tools.
• Professional experience working with Versal, MicroBlaze, bare metal development, and kernel/device drivers.
• Professional 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 full spaced-based System lifecycle including requirements flow down and 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 framework 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 p]]>
