You will investigate vulnerabilities, debug test setups, and collaborate closely with hardware, software, and FPGA engineering teams. This role is critical in shaping the security verification strategy, guiding less experienced engineers, and driving the growth of Innoflight’s security engineering capabilities.

Active U.S. Security Clearance required.

WHAT YOU'LL DO:

• Lead Security Verification Practices: Develop and execute test plans, automation scripts, and verification procedures to validate product security requirements.
• Investigate & Resolve Issues: Perform in-depth analysis of test anomalies and vulnerabilities, working with hardware, software, and FPGA teams to troubleshoot and resolve findings.
• Build Automation Capabilities: Create and enhance Python-based test automation frameworks to improve efficiency, repeatability, and reliability of security testing.
• Mentor & Guide: Provide guidance to junior engineers and future hires, establishing best practices and sharing expertise in security verification and test automation.
• Collaborate Cross-Functionally: Work closely with engineering, manufacturing, and quality teams to integrate, test, and release secure products.
• Contribute to Process Improvement: Identify gaps, propose improvements, and implement standards for security testing and verification processes.
• Maintain Documentation: Keep detailed records of test plans, results, automation workflows, and lessons learned for internal and customer reporting.
• Support Department Growth: Help define staffing, skills, and processes for building a scalable security engineering function.

YOU’RE AWESOME AT:

• Security Engineering Expertise: Deep understanding of vulnerability testing, cryptography, and secure communication systems.
• Automation & Tooling: Proficiency in Python-based automation; familiarity with Linux and test frameworks. Knowledge of Rust, JavaScript, or MongoDB is a plus.
• Problem-Solving & Analysis: Ability to troubleshoot complex hardware/software/FPGA systems and identify root causes.
• Mentorship & Collaboration: Able to guide others, share knowledge, and work effectively across diverse technical teams.
• Communication & Documentation: Skilled at writing clear technical documentation and presenting findings to technical and non-technical stakeholders.

WHAT YOU’LL NEED:

• Bachelor’s degree in Computer Science, Engineering, or a related field.
• 7 or more years in software integration, security verification testing, or related roles, with progression from Level II responsibilities.
• 5 or more years in security vulnerability testing and secure cryptographic communication systems.
• Strong Python experience; familiarity with Rust, JavaScript, MongoDB, and Linux is a plus.
• Advanced ability to debug software, embedded systems, and hardware communication interfaces.
• Proven ability to lead cross-functional collaboration and mentor less experienced engineers.
