Description du poste

We don't just build technology-we engineer the future. From next-gen aerospace to cutting-edge defense systems, we tackle the toughest, mission-critical challenges that keep people safe and push the limits of innovation. This is where problem-solvers, innovators, and big thinkers thrive.

Location: Cedar Rapids, Iowa (Full‑time Onsite)

Quest Defense Systems & Solutions is seeking a Senior Systems Engineer with a strong background in systems architecture, requirements development, integration, and verification for advanced weapons systems. This role will support the development and sustainment of GPS‑enabled guidance and navigation solutions for next‑generation weapon platforms.

This position offers the opportunity to work hands‑on with cutting‑edge GPS receiver technology, resilient navigation methods, and mission‑critical flight hardware. Engineers in this role gain deep technical insight into GPS architecture, signal processing, and weapons system integration-all while contributing to the advancement of Quest's precision‑guided weapon product lines.

Because of the need for consistent, secure, on‑site collaboration and specialized hardware access, this role is performed 100% onsite at our Cedar Rapids engineering facility.

Join Quest in our mission to deliver reliable, high‑assurance systems that support those who protect our nation.

Key Responsibilities

• Lead systems engineering activities spanning requirements development, system architecture, interface definition, test planning, integration, and qualification for weapons‑class GPS systems.
• Define and analyze system‑level requirements, decompositions, and traceability within a formal systems engineering framework.
• Support integration of GPS receivers and navigation subsystems into weapon platforms, collaborating closely with software, hardware, firmware, and test disciplines.
• Develop system‑level test plans, verification procedures, and qualification artifacts.
• Conduct technical reviews, support design maturation, and evaluate system performance in lab and field environments.
• Serve as a technical liaison for customers, internal stakeholders, and cross‑functional teams.
• Support issue resolution, configuration management, and risk mitigation activities throughout the product lifecycle.

Required Education, Experience & Skills

• Bachelor's degree in a STEM discipline (Engineering, Computer Science, Physics, Mathematics, etc.) with a minimum of 4 years of relevant engineering experience.
• Strong understanding of formal systems engineering processes and product development methodologies.
• U.S. Citizenship is required.
• Ability to obtain and maintain a U.S. DoD Secret clearance.

Preferred Education, Experience & Skills

• Active DoD Secret clearance (or higher).
• Experience with systems engineering tools such as DOORS, JAMA, or Jira.
• Experience with Model‑Based Systems Engineering (MBSE) methodologies or tools (SysML, Cameo, Rhapsody).
• Familiarity with modern programming or scripting languages (C, C++, Python).
• Demonstrated ability to solve complex, multi‑disciplinary engineering problems.
• Ability to produce clear, complete technical documentation and communication for diverse audiences.
• Experience integrating navigation systems, GPS receivers, or weapon guidance subsystems.
• Ability to work effectively in a high‑performing, mission‑focused engineering team.
• Proactive, results‑driven mindset with a strong desire to innovate and improve systems.
