Embedded Software Engineer Sr - E3

Standard Job Description

What We're Doing

The coolest jobs on this planet… or any other… are with Lockheed Martin!

At Lockheed Martin Rotary and Mission Systems in Owego, NY, we develop mission‑critical embedded software and advanced technologies for complex defense and aerospace systems. Our software supports safety‑critical avionics, mission computers, embedded processing, and secure systems where reliability and performance matter.

The Work

As a Level 3 Senior Software Engineer, you'll work across the software development lifecycle, taking ownership of complex technical assignments and developing solutions that move from design into real mission systems. You’ll turn requirements into solutions, solve problems, and collaborate across engineering disciplines to deliver mission‑critical capabilities.

You’ll have the opportunity to:

• Design, develop, integrate, test, debug, and maintain embedded software for avionics and mission computers – from device drivers and boot loaders to built‑in‑test (BIT) libraries.
• Analyze requirements and develop software designs that run on Real‑Time Operating Systems and hypervisors such as LynxOS, Windriver VxWorks, or Green Hills Integrity.
• Perform hands‑on software/hardware integration, verification, troubleshooting, and system‑level debugging using target hardware and laboratory instrumentation.
• Analyze and resolve complex issues involving processors, FPGAs, peripherals, and hardware/software interfaces.
• Apply software‑engineering standards, development processes, configuration management, and coding best practices.
• Support modern DevSecOps practices, including CI/CD and automated testing.
• Participate in peer reviews and technical design discussions.
• Provide technical guidance and mentorship to junior engineers.

Who We Are

RMS Owego brings together software, systems, hardware, and integration expertise to develop advanced mission solutions. Our engineers work with real mission hardware in onsite laboratories, taking software from architecture and design through integration, test, and delivery.

Who You Are

You’re an experienced engineer who enjoys solving problems and figuring out how things work. You can independently tackle significant technical challenges, communicate effectively, collaborate across engineering disciplines, and apply sound engineering judgment.

Why Join Us

At Lockheed Martin, you'll work alongside experienced engineers on technology with real‑world mission impact while continuing to grow your technical expertise. We offer flexible schedules, including 4×10 and Flex Time, comprehensive benefits, career development and mentorship, and hands‑on opportunities from early development through laboratory integration and testing.

Bring your ideas. Own the challenge. Build what’s next.

Basic Qualifications

• 5+ years related experience with an Associates Degree in STEM related field.
• Experience developing C code for embedded environments.
• Familiar with developing and debugging software that controls embedded hardware, firmware, and FPGAs. Knowledge of hardware communication protocols such as PCIe, SPI, UART, and I2C.
• Experience developing, integrating, and debugging software within a Real-Time Operating System (RTOS) or embedded Linux environment (e.g., Wind River VxWorks, LynxOS, Green Hills Integrity, or similar).
