The engineer collaborates with multidisciplinary engineering teams, follows aerospace software processes, and delivers software meeting strict functional and performance requirements.

The role involves leading product transitions, owning fabrication and assembly processes, continuous improvement, and conducting design reviews for propulsion systems.

The Senior Hardware Design Engineer will lead circuit card development, collaborate with teams on avionics platforms, and troubleshoot designs for space applications.

The Propulsion Engineer II will design, develop, and deliver propulsion components, manage product lifecycle, and lead cross-functional teams for high-performance valve systems.

Own planning, scheduling, and execution for avionics development across hardware, firmware, harnessing, launch vehicle, and spacecraft systems. Build and maintain integrated schedules, track risks and backlogs, support staffing and budgets, interface with program management, prepare design review documentation, automate metrics with Python/SQL, and maintain visibility using Jira/Confluence.

Develop interactive SCORM-compliant eLearning courses and multimedia assets from instructional designs using Articulate 360 and video tools. Produce/edit instructional video and motion graphics, apply accessibility and branding standards, publish and test LMS content, leverage generative AI to accelerate workflows, maintain and refresh training materials, and collaborate with designers and subject-matter experts.

Design, develop, and validate guidance, navigation, and control (GNC) software and simulations for launch vehicles. Perform 6DOF dynamics, tuning of attitude control, sensor/actuator modeling, stability and sensitivity analyses, hardware-in-the-loop testing, mission operations support, and post-flight analysis. Interface with cross-disciplinary teams and author technical documentation to improve GNC systems and tools.

Design, implement, and maintain infrastructure-as-code and CI/CD pipelines (Terraform, Jenkins); administer Linux servers; automate operations; implement monitoring and security controls; troubleshoot incidents and participate in on-call rotation.

Lead information assurance for space and enterprise systems, map CNSSP-12 into engineering requirements, manage RMF (NIST SP 800-37) accreditation to obtain ATOs, enforce NIST/CMMC/STIG compliance, run risk assessments, oversee compliance teams, incident response, and red-team/testing to ensure secure architectures for ground and space segments.

Lead and maintain security for DoD/IC programs including SCIF management, security plans, incident investigations, personnel and information security, classified material handling, IC security assessments, and program security compliance with NISPOM, ICDs, and DoD policies. Provide oversight, training, and support for classified launch campaigns and integration.

Design, analyze, and deliver spacecraft separation and interfacing mechanisms across the product lifecycle. Own conceptual design, sizing and strength calculations, CAD and manufacturing drawings, hardware development, qualification testing, requirements generation, trade studies, and compliance with relevant launch standards. Collaborate cross-functionally and improve processes.

Lead a flight dynamics team delivering mission design, orbit determination, and maneuver planning for LEO and cislunar spacecraft. Manage hiring, performance, budgets, roadmaps, and cross-functional delivery while improving tools, processes, and team capabilities to support operational missions.

Lead and grow an ADCS team responsible for attitude determination and control across LEO and cislunar missions. Own team leadership, hiring, performance management, budgeting, roadmap and strategy, and day-to-day delivery of ADCS software, analysis, and flight operations while interfacing with program managers and stakeholders to meet mission schedules and technical standards.

Manage payload and spacecraft integration activities, serve as primary technical/programmatic interface to customers (NASA, FAA, USAF, commercial), develop interface requirements and ICDs, resolve technical FFF and environmental issues, coordinate integration, testing, launch, and operations, and lead design reviews and technical interchange meetings.

Lead end-to-end mission operations for lunar and LEO/GEO missions: define ground-segment requirements, develop flight operations products (procedures, scripts, automation), run simulations and training, supervise mission simulations, and staff/lead real-time console operations for assigned spacecraft subsystems.

Lead end-to-end mission operations for lunar and multi-manifested missions: architect ground segment, develop flight operations products, run simulation and training campaigns, direct verification/validation, manage configuration and access, lead mission execution consoles, and coordinate cross-team stakeholders from planning through mission operations.

As a Spacecraft Systems Engineer II, you will develop spacecraft systems, manage technical budgets, validate architecture, and ensure operational efficiency for space missions.
