Job description

About Beacon AI

We’s a fast-moving team of aviators, engineers, and operators building an AI platform to make flying safer, more efficient, and more capable. Backed by top investors, we’ve secured a dozen Department of Defense contracts and partnered with major airlines to deliver mission-critical systems. We operate without silos or heavy processes. Small, focused teams own what they build, ship quickly, and learn fast, pushing the boundaries of how humans and AI work together in aviation.

Role Overview

We are seeking a Lead Security Software Engineer to ensure the security and integrity of Beacon AI’s systems and data across commercial and Department of Defense (DoD) environments. This is a hands‑on security engineering role focused on designing and operating secure systems, partnering closely with software teams, and protecting mission‑critical flight safety technology while meeting applicable security standards.

What You’ll Do

• Design and implement secure architectures across applications, cloud infrastructure, and data systems.
• Protect sensitive data through strong controls for access management, encryption, and secure data handling.
• Identify, assess, and mitigate security risks through vulnerability assessments, penetration testing, and security reviews.
• Lead incident response efforts, including detection, containment, remediation, and follow‑up analysis.
• Integrate security best practices into the SDLC by working closely with software engineering teams.
• Implement and operate security monitoring and logging to detect and respond to threats in real time.

What Will Make You Successful

• 5–9 years of hands‑on experience in security engineering roles securing complex systems and data.
• Strong knowledge of security principles, threat modeling, and defensive security practices.
• Experience with common security tools and technologies (e.g., SIEM, IDS/IPS, vulnerability scanning, encryption).
• Familiarity with security and compliance frameworks such as NIST, ISO 27001, and CMMC.
• Proven ability to collaborate effectively with software engineers on secure system design.
• Hands‑on mindset with strong analytical and problem‑solving skills.

Bonus Points

• Passion for aviation and a desire to improve air travel efficiency and safety.
• Experience working with aviation, aerospace, or DoD customers.
• Familiarity with zero trust architectures or advanced security approaches.
• Relevant security certifications such as CISSP, CISM, or CEH.

Work Location

This is a hybrid role based in San Carlos, CA, with 3+ days per week onsite and the option to work remotely on remaining days.
