Job description

CoAspire (https://www.coaspire.com) is a cutting-edge defense manufacturing leader in Northern Virginia, specializing in the precision assembly of advanced weapons systems. With over twelve years of a legacy of innovation, we're at the forefront of building reliable, affordable mass weapons that protect and empower our nation’s warfighters. Our tight-knit team thrives in a collaborative environment where safety, quality, and work‑life balance come first with a focus on professional growth at our new 27,000+ sq. ft. facility. Join us to make a tangible impact on mission‑critical technology while enjoying Northern Virginia's vibrant community.

Position: 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.

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.

Qualifications

• 2-7 years of software engineering experience in aerospace/defense or related field.
• Bachelor’s degree in Computer Science, Software Engineering, Computer Engineering, 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.

Desired Skills

• 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
