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 Secret clearance
Qualifications:
- Bachelor’s Degree and minimum 4 years of prior relevant experience. Graduate Degree and a minimum of 2 years of prior related experience. In lieu of a degree, minimum of 8 years of prior related experience.
Preferred Additional Skills:
- Strong 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
- Ability to work independently with minimal supervision while contributing effectively to a team environment
- 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.
