Senior Network Security Engineer

Senior Network Security Engineer

This role sits at the core of a modern, high-scale engineering environment where security is treated as a first-class design principle rather than a downstream control. The engineer will help design, build, and operate defensive network security systems that protect cloud, corporate, and production infrastructure across complex distributed environments. It is a hands-on technical role for someone who thrives in deep system work—across routing, cloud architecture, and application-layer security. You will partner closely with infrastructure, platform, and software engineering teams to ensure systems are secure by design. The environment is fast-moving, autonomous, and highly collaborative, with a strong emphasis on ownership and engineering excellence. This position offers the opportunity to shape security architecture at scale while directly influencing resilience against real-world threats.

Accountabilities

• Design, implement, and evolve network security architecture across cloud, production, and enterprise environments, ensuring resilient and scalable defensive controls
• Develop and maintain security tooling and automation to improve threat detection, visibility, and response across distributed systems
• Conduct security-focused network architecture and design reviews, ensuring secure-by-design principles are embedded in infrastructure decisions
• Build and deploy network-based defensive mechanisms, including access controls, segmentation, monitoring, and anomaly detection systems
• Partner with infrastructure, networking, and platform teams to integrate security into system design, CI/CD pipelines, and deployment workflows
• Support incident response activities, including investigation, mitigation, post-incident analysis, and long-term remediation efforts
• Drive security engineering initiatives independently while influencing a security-first culture across technical teams

Requirements

• 6+ years of experience in software engineering, network security engineering, or infrastructure security roles
• Strong understanding of routing, switching, network architecture, and distributed systems design principles
• Experience conducting security-focused architecture reviews and identifying systemic risks in networked environments
• Proficiency in at least one programming language (Python, Go, Rust, or similar) for automation and tooling development
• Hands-on experience with cloud platforms such as AWS, Azure, or GCP and their security ecosystems
• Familiarity with infrastructure-as-code tools (e.g., Terraform, AWS CDK) in production environments
• Experience building or operating network-based security controls, monitoring systems, or detection pipelines
• Background in incident response, including investigation and remediation of security incidents
• Strong communication skills with the ability to collaborate across engineering, infrastructure, and security teams
• Eligibility to obtain and maintain a U.S. security clearance is required

Benefits

• Competitive base salary with a range typically between $128,000 and $220,000 USD depending on experience
• Equity opportunities as part of the total compensation package
• Comprehensive health, dental, and vision insurance coverage
• Flexible work arrangements with remote-friendly culture
• Opportunity to work on large-scale, high-impact systems in a mission-driven environment
• Professional growth in advanced security engineering, cloud infrastructure, and distributed systems
• Inclusive engineering culture focused on ownership, autonomy, and technical excellence
