Job Description:

At L3Harris, our software engineers solve meaningful problems that directly impact missions across the globe. We foster a culture of innovation and value individuals from diverse backgrounds who challenge assumptions, introduce new ideas, and push the boundaries of what’s possible. Our teams work across the full engineering lifecycle—from concept and architecture through deployment, sustainment, and evolution of real operational systems.

We’re expanding to meet growing demand in space and airborne technologies, and we’re looking for versatile software engineers who thrive on curiosity, enjoy tackling complex technical challenges, and can contribute across embedded, application and cloud environments.

Day to day, you will collaborate with cross-functional engineering teams on requirements, design, integration, hardware/software interfaces, testing, debugging, and defect resolution across the full software development lifecycle. You will also use a wide range of programming languages, tools, and operating systems to build, evaluate, and document software solutions for embedded and platform-based environments. 

Essential Functions:

• Analyze system and software requirements, develop use cases, and translate them into architecture, design, and implementation tasks
• Design, implement, integrate, and test software components
• Develop and maintain software in C++ using low‑level techniques such as memory management, bit‑level data manipulation, and hardware‑adjacent integration
• Diagnose, troubleshoot, and resolve software defects or system integration issues, including support for deployed operational systems
• Collaborate with customers and cross‑functional engineering teams to clarify requirements, support operations, and identify technical improvements
• Produce and maintain technical documentation, participate in design/code reviews, and contribute to continuous improvement of engineering processes
• Travel up to 10%
• Ability to obtain a US Secret security clearance

Qualifications:

• Bachelor's Degree with 4 years prior experience, Graduate Degree with 2 years of prior related experience. In lieu of a degree, minimum of 8 years of prior related experience.

Preferred Additional Skills:

• Understanding of object oriented esign, multi-threaded programming, concurrency models, and synchronization techniques
• Experience with RTOS (e.g., FreeRTOS, Linux), simulators, and programming languages (C/C++, Python, scripting).
• Experience with embedded controllers (e.g., PIC, STM), serial communications (e.g., TCP/IP, RS422), and distributed messaging (TCP/UDP).
• Proficiency with Java, Python, Rust
• Understanding of cloud and AI technologies and integration
• Experience developing software for space, aerospace, or defense systems

In compliance with pay transparency requirements, the salary range for this role in California, Massachusetts, New Jersey, Washington, and the Greater D.C, Denver, or NYC areas is $97,000 -$180,000. This is not a guarantee of compensation or salary, as final offer amount may vary based on factors including but not limited to experience and geographic location. L3Harris also offers a variety of benefits, including health and disability insurance, 401(k) match, flexible spending accounts, EAP, education assistance, parental leave, paid time off, and company-paid holidays. The specific programs and options available to an employee may vary depending on date of hire, schedule type, and the applicability of collective bargaining agreements.
