Systems Engineer II; Secret Clearance Required

About the Role

The Systems Engineer II contributes to the development and implementation of advanced system solutions by providing alignment, connection, and direction to the technical team throughout the product development lifecycle. The role represents the viewpoint of the integrated whole during system development and works to glue segments and subsystems together via top‑down decomposition of stakeholder requirements, traceability through development artifacts, and bottom‑up validation and verification of the system.

Responsibilities include shepherding the team through technical development milestones, tracking performance measures, and identifying technical risks to arrive at a compliant and cohesive system solution. A firm grasp of Systems Engineering principles and specific expertise in requirements management, system architecture development, concept of operation definition, system integration, and system verification is expected.

• Design and maintain ground system architectures including mission operations centers, ground data systems, ground communication networks, and interfaces with launch site infrastructure and tracking stations.
• Develop ground software and tools for vehicle monitoring, telemetry processing, command & control, and support pre‑launch checkout, mission simulations, and ground rehearsals.
• Coordinate ground segment integration with flight systems and ensure end‑to‑end operational readiness.

• Derive, decompose, and manage technical requirements from stakeholder needs through system, subsystem, and component levels; manage requirements baseline changes and impact assessments across the product lifecycle.
• Develop verification and validation strategies, including analysis, inspection, demonstration, and test methods; author verification procedures, test plans, and acceptance criteria aligned to requirements traceability.
• Lead requirements reviews, trade studies, and technical audits to ensure completeness, consistency, and compliance.

• Plan and execute hardware and software integration activities for spacecraft buses, payloads, and subsystems; coordinate interface control documents (ICDs) and manage technical interfaces across vehicle elements.
• Support integration and test campaigns, including functional checkout, environmental testing, and system‑level qualification; resolve integration anomalies and provide troubleshooting across mechanical, electrical, thermal, and software domains.
• Collaborate with manufacturing, quality, and mission assurance teams to ensure flight readiness.

• Bachelor’s degree in a related field (or equivalent work experience). Typically 2+ years of related experience.
• Practical understanding of Systems Engineering principles and practices, including a basic understanding of the systems development lifecycle.
• Conceptual knowledge of requirements management, functional requirements parsing, derivation, and allocation.
• Conceptual knowledge of systems architecture, systems integration, and Verification and Validation (V&V) principles.
• Clear verbal and written communication of technical concepts and information.
• Active Secret U.S. Security Clearance required.

• Master’s degree in Engineering, Physics, or a related field.
• Experience with Requirements Management and Model Based Systems Engineering tools and frameworks such as DOORS, CAMEO EA, Rhapsody, Matlab, and SysML.
• Basic understanding of spacecraft systems, including hardware and software subsystems and components.
• Familiarity with project management methodologies including risk management and technical performance tracking.
• Familiarity with technical baseline and configuration management.
• Experience or certification in INCOSE standards.
• Excellent problem‑solving skills and attention to detail.
• Ability to adapt to a fast‑paced and dynamic work environment.

Pay will be determined on a case‑by‑case basis and may vary based on job‑related knowledge, skills, education, experience, internal equity, and market competitiveness.

• Medical, dental, and vision plans.
• 401(k) with 150% match up to 6%.
• Life insurance.
• 3 weeks paid time off.
• Additional benefits as applicable.
