Senior Security Engineer

Viasat is a company on a mission to deliver connections with the capacity to change the world. They are seeking a Senior Security Engineer for the Global Mobility Labs to develop and oversee security strategies, ensuring that lab environments are resilient against evolving threats while maintaining innovation speed.

Responsibilities:

• Build and lead the security strategy for our mobility labs across all global locations, moving the organization from zero-coverage to a proactive, hardened security posture
• Conduct comprehensive security reviews and technical assessments of experimental hardware, software, and 5G/SATCOM technologies before they are coordinated into the lab environment
• Orchestrate the full lifecycle of vulnerability discovery and remediation, ensuring that diverse and specialized lab systems are patched and hardened against lateral movement
• Translate foundational corporate security principles into practical, lab-specific policies that enable researchers to work efficiently while maintaining strict electronic security controls
• Serve as the primary liaison between the Mobility Labs and the Corporate IT Security team, ensuring global operations remain aligned with enterprise-wide security mandates
• Monitor the lab environment for emerging threats, implement network security controls (firewalls, IDS, access controls), and act as the lead for any lab-specific security incidents
• Act as an advocate for security procedures within the R&D teams, providing guidance and training to foster a 'secure-by-design' mentality across the innovation pipeline

Requirements:

• 5+ years in a hands-on security engineering role, preferably within a research and development (R&D), lab, or high-tech manufacturing environment
• Deep expertise in vulnerability management and remediation, including experience with tools like Nessus, Qualys, or Rapid7, and the ability to manage sophisticated patch lifecycles across diverse OS environments (Linux, Windows, etc.)
• Strong understanding of network architecture, including hands-on experience configuring and maintaining firewalls, IDS/IPS, and secure access controls (VPN, Zero Trust)
• Proven ability to translate high-level corporate security mandates into practical, technical SOPs (Standard Operating Procedures) that work in a fast-paced lab setting
• Outstanding communication and interpersonal skills. You must be able to advocate for security procedures in a way that enables—rather than hinders—innovation and speed
• The ability to secure 'non-standard' or experimental hardware and software that doesn't always fit into traditional corporate IT boxes
• CISSP, GSEC, CEH, or specific network/cloud security certifications (CCNA Security, AWS/Azure Security)
• Familiarity with 5G /WIMAX architecture, SATCOM technologies, or RF (Radio Frequency) security
• Experience managing security for geographically distributed teams or lab facilities
• Experience with forensic investigation tools and incident response protocols in a networked environment
