Software Developer - Test Lead

Job Summary

The Test Lead will play a critical, hands‑on role in the iterative development, integration, and verification of advanced ground software systems supporting the U.S. Search and Rescue Satellite‑Aided Tracking (SARSAT) Program. This position supports the Search and Rescue Intelligence for Rescue Navigation (SIREN) AI‑enabled software tool suite and its integration into the SAR Intelligent Terminal (SAINT) operational system.

This role emphasizes CI/CD‑enabled development, rapid prototyping, and the implementation of an Automated Testing Framework (ATF) to enable frequent, reliable software releases while maintaining the rigor required for mission‑ and safety‑critical systems. The Developer/Test Lead will ensure software maturity through Critical Design Review (CDR) and future development phases.

Location:

This position is located at Goddard Space Flight Center in Greenbelt, MD with a hybrid schedule. Subject to change but minimum Wednesday in office and other days' work from home.

• Define, implement, and maintain an Automated Testing Framework (ATF) supporting unit, integration, regression, and system‑level testing.
• Integrate automated testing into CI/CD pipelines to provide fast feedback on code quality, functional correctness, and performance.
• Ensure test artifacts provide requirements‑based traceability and objective evidence for verification and validation activities.
• Lead defect triage, root‑cause analysis, and corrective action through closure.

• Support derivation of lower‑level software requirements from government‑provided L1/L2 (SIREN) and L3 (SAINT) requirements.
• Participate in software architecture and design reviews to ensure testability, automation, and maintainability are built into the system.
• Review and address existing SAINT open work items as part of iterative development cycles.

• Implement and test integration with SARSAT registration databases, incident history systems, and external data sources.
• Validate AI/ML‑enhanced outputs to ensure reliability, repeatability, and operational suitability.
• Support integration of SIREN capabilities into SAINT user workflows and user interfaces.

• Prepare technical inputs and support major lifecycle reviews, including Critical Design Review (CDR).
• Develop and maintain software development, CI/CD, and test documentation as defined in the SOW deliverables.
• Ensure development, automation, and test practices comply with NPR 7150.2D, GPR 7150.1, and tailored Class B software requirements.

• Strong software development experience in modern programming languages.
• Hands‑on experience designing or operating CI/CD pipelines for iterative development.
• Experience implementing automated testing frameworks and integrating them into Build pipelines.
• Familiarity with requirements‑based testing and configuration management.
• Experience integrating software with databases, APIs, and external data sources.
• Exposure to AI/ML‑enabled systems or data analytics is highly desirable.

• Ability to lead testers and testing activities while remaining hands‑on with implementation and automation.
• Strong analytical and problem‑solving skills.
• Effective communication skills for coordination with systems engineering, project management, and government stakeholders.
