Job description

Systems Engineer - Defense Integrated Systems

Palmer Lake , CO / Parker , CO / Springfield , OH

We are seeking a highly skilled and motivated Systems Engineer to support the design, integration, and lifecycle execution of complex defense systems spanning military aircraft, expeditionary shelter systems, and secure (SCIF) environments. This role focuses on translating operational needs into technically sound, certifiable designs that integrate mechanical, electrical, power, network, and software subsystems into cohesive, mission-ready solutions. The ideal candidate will embody our core values: Deploy Faster, Operate with Confidence, and Design with Purpose, ensuring that solutions are rapidly delivered, reliable in execution, and intentionally designed to meet mission objectives.

Travel: 10-15% travel will be required between our Colorado and Ohio facilities.

What You’ll Do

• Lead systems engineering activities across the full system lifecycle, including requirements development, architecture definition, trade studies, integration, verification, and validation.
• Develop, manage, and maintain system requirements, Interface Control Documents (ICDs), Concepts of Operations (CONOPS), and technical baselines.
• Architect and integrate multi-domain defense systems, including:
  • Aircraft-installed systems (ISR, communications, power distribution, and networking)
  • Transportable and modular expeditionary shelter systems
  • SCIF and secure communications environments
• Coordinate integration efforts across mechanical, electrical, power, thermal, EMI/EMC, network, and software domains.
• Support aircraft modification efforts, including non-permanent (e.g., T-2/T-3) installations, while minimizing airworthiness and certification risk.
• Perform technical trade studies to balance performance, cost, schedule, and program risk.
• Develop and support system verification and validation plans, test procedures, and acceptance activities (ground and flight test, as applicable).
• Collaborate with program management, manufacturing, test, and customers to ensure technical alignment and successful execution.
• Identify, track, and mitigate technical risks throughout design and integration activities.
• Contribute to proposal development efforts, including ROMs, schedules, system architectures, and technical volumes, as required.
• Apply our core values in daily work: Deploy Faster by streamlining integration and delivery processes, Operate with Confidence by ensuring systems are reliable and certifiable, and Design with Purpose by making intentional, mission-focused design decisions.

What You Bring

• Bachelor’s degree in Systems Engineering, Aerospace Engineering, Electrical Engineering, Mechanical Engineering, or a related technical field.
• 5+ years of experience in systems engineering or integrated product development within defense or aerospace environments.
• Experience supporting military platforms, aircraft systems, or deployable/expeditionary defense infrastructure.
• Strong understanding of:
• Requirements development, management, and traceability
• System architecture definition and subsystem integration
• Verification and validation planning and execution
• Familiarity with DoD acquisition environments and technical documentation standards.
• Ability to clearly communicate complex technical concepts to both technical and non-technical stakeholders.
• Experience with military aircraft modification programs (e.g., C-130, C-17, ISR or special mission platforms).
• Experience with expeditionary, transportable, or modular shelter systems.
• Experience with SCIF design, secure networking, or TEMPEST considerations.
• Familiarity with applicable MIL-STD requirements (e.g., MIL-STD-810, MIL-STD-461, MIL-STD-704).
• Experience using Model-Based Systems Engineering (MBSE) tools such as SysML, Cameo, DOORS, or similar.
• Background in communications, SATCOM, ISR, or mission systems integration.
• Must be able to qualify for and maintain at least a SecretSecurity Clearance.
