About The Position

SSAI seeks a Systems Engineer III to support an Earth Science contract at NASA Goddard Space Flight Center. The candidate will provide systems engineering, data processing, and operations support. This individual acts as the technical integrator and problem-solver, keeping the mission aligned, stable, and science-ready. You will ensure that the mission’s instruments, software, data systems, and operations all work together reliably to meet science and mission requirements.

Requirements

• Bachelor’s degree in computer science, systems engineering, physics, atmospheric science or related field and 8 years’ experience in software engineering or development. Or, the equivalent combination of education and experience.
• Ability to work independently, lead technical efforts, and integrate across disciplines.
• Strong background in systems engineering principles: requirements development and traceability, interface control, verification & validation (V&V), and configuration management.
• Experience with spaceflight or Earth science missions, including instrument, spacecraft, and ground system integration.
• Ability to analyze system performance, telemetry, trends, and anomalies across instruments and spacecraft subsystems.
• Experience with system integration and test (I&T), anomaly resolution, and operational risk assessment.

Nice To Haves

• Knowledge of validation and matchup methodologies for Earth science data products is a strong plus.
• Ability to assess trade studies and impacts across mission elements.

Responsibilities

• Mission Integration & Requirements Management: Translate science and mission objectives into system requirements, ensure consistency across instruments (OCI, HARP2, SPEXone), spacecraft, ground systems, and operations, and manage interfaces between teams.
• Operations & Performance Oversight: Coordinate with the Mission Operations Center on planning, instrument activities, and calibration strategies; monitor telemetry, trends, and system health to identify and resolve issues.
• Verification, Validation & Risk Management: Define and oversee test plans, validate system performance (including data quality and processing), manage configuration control, and assess risks to mission operations and science data continuity.
• Lifecycle & Stakeholder Coordination: Support the full mission lifecycle—from development through on-orbit operations—while facilitating communication among scientists, engineers, software developers, and external partners to ensure mission success.
