What you will do:

You will contribute to the design, development, integration, and test of embedded and application software for advanced missile programs. This cross-functional role involves close collaboration with systems engineering, electrical/hardware design, guidance, and test teams to deliver reliable, real-time software solutions. There are multiple needs: supporting embedded operational flight program (OFP) efforts, creating test and automation software (primarily on Windows platforms), implementing specialized flight algorithms, and supporting integration and qualification testing — all while ensuring compliance with performance, safety, security, and (near) real-time requirements.

Location: Fairfax, VA

Responsibilities:

• Support the design, development, modification, and review of embedded software in C/C++ for missile flight control and supporting subsystems.
• Develop test programs, automation scripts, and graphical user interfaces (GUIs), primarily on Windows platforms, to support software-in-the-loop (SIL), hardware-in-the-loop (HWIL), integration, and qualification testing.
• Implement, optimize, and verify guidance, control, and signal-processing algorithms.
• Support software-hardware integration, including debugging, interface definition, and real-time performance analysis.
• Conduct unit and system testing, end-to-end integration testing, code reviews, and support system-level verification and flight-worthiness testing.
• Perform root-cause analysis on software issues, implement fixes, and support configuration management and change processes.
• Generate and maintain software documentation (in line with Model Based System Engineering (MBSE) expectations), including requirements specifications, design descriptions, test plans, and reports.
• Ensure all software complies with customer-required guidelines, coding standards and security requirements.

Basic Qualifications:

• Bachelor’s degree in Computer Science, Software Engineering, Computer Engineering, or related field.
• 5-10 years of software engineering experience in aerospace/defense or related field.
• Proficiency in C/C++ for embedded or real-time applications.
• Experience with embedded software development, debugging tools, and version control (e.g., Git, GitHub, Kanban-based agile development).
• Familiarity with real-time systems, multithreading, and basic software-hardware interfacing.
• U.S. citizenship and current Secret clearance (or ability to obtain and maintain one).
• Excellent communication skills and ability to work effectively in cross-functional teams.

Preferred Qualifications:

• Experience with TypeScript/JavaScript for test application and GUI development.
• Experience with Windows-based test environments, automation frameworks, or lab integration tools.
• Familiarity with Cameo for MBSE efforts.

What We Offer:

Beyond competitive pay, we offer:

• Full benefits from day one: medical, dental and vision
• 401(k) with generous company match and immediate vesting
• PTO and Federal holidays
