Cyber Software Test Engineer

Job Description

You will be the Cyber Test Exploitation Engineer for the research and development team, responsible for designing, executing, and automating exploitation-focused test campaigns **and** performing comprehensive software testing to evaluate emerging technologies and ensure mission-critical resilience.

What You Will Be Doing

As the Cyber Test Exploitation Engineer, you will develop and run sophisticated test-and-exploit methodologies, conduct core software-testing activities, collaborate closely with customers and internal stakeholders throughout the development lifecycle, and help shape a culture of continuous security improvement.

Your responsibilities will include:

• Designing and implementing automated exploitation frameworks and test suites for novel cyber-engineering technologies.
• Conducting hands-on penetration testing, vulnerability analysis, and proof-of-concept exploits against prototypes and operational systems.
• Developing, executing, and maintaining functional, regression, and integration test cases to verify that software behaves as intended.
• Creating automated test scripts (e.g., using Python, PowerShell, or CI/CD tools) to increase test coverage and reduce manual effort.
• Tracking test results, logging defects, and coordinating mitigation activities with development teams.
• Documenting findings, generating actionable remediation recommendations, and presenting results to customers and senior leadership.
• Partnering with software engineers, system architects, and mission customers to embed security-by-design and quality-by-design principles early in development.
• Mentoring team members on exploitation techniques, software-testing best practices, and tool development.
• Contributing to a high-performing, innovative team environment that values curiosity, creativity, and a one-team mindset.
