Job description

SR. NETWORK SECURITY ENGINEER

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

RESPONSIBILITIES

• Provide subject matter expertise on network security, firewalls, zero-trust architectures, and industry best practices, with primary focus on modern remote access VPN technologies.
• Architect, design, deploy, and secure enterprise remote access VPN solutions end-to-end (including supporting components such as routers, exit nodes, and connectors), with strong emphasis on Tailscale, WireGuard, IPsec, and SSL-based implementations.
• Own the full lifecycle of remote access infrastructure from initial design and ground-up implementation through ongoing management, policy definition, client distribution, and performance optimization.
• Configure, deploy, and support VPN clients across multiple platforms (Windows, macOS, Linux, iOS, Android) while performing advanced troubleshooting of complex connectivity and performance issues.
• Manage Linux-based infrastructure and network security systems with end-to-end ownership of configuration, custom tooling, and operational reliability.
• Develop automation and CI/CD workflows (Python or similar) to streamline deployment, policy enforcement, monitoring, and maintenance of remote access and security systems.
• Implement and support zero-trust remote access architectures; manage firewall policies and network security appliances with tight integration of VPN solutions.
• Serve as an escalation point for complex network security and remote connectivity challenges; collaborate cross-functionally with engineering and operations teams to gather requirements, design secure solutions, and communicate best practices.
• Monitor VPN performance, logs, and overall security posture; proactively identify issues, drive resolutions, and formalize processes and change management for remote access infrastructure.
• Apply system patches, perform periodic maintenance, and continuously improve the reliability and security of the remote access environment.

BASIC QUALIFICATIONS

• Bachelor's degree in a STEM field and 5+ years of network security experience; OR 8+ years of network security experience in lieu of a degree.
• 3+ years of experience securing networks, IT infrastructure, applications, endpoints, and/or APIs.

PREFERRED SKILLS AND EXPERIENCE

• Proven experience leading the design, deployment, and operation of enterprise remote access VPN solutions (Tailscale, WireGuard, or comparable SSL/IPsec/WireGuard-based platforms) in large-scale, multi-site or multi-region environments with high reliability requirements.
• Deep hands-on expertise with modern remote access platforms, including client management, access policies, split-tunneling, performance tuning, and complex troubleshooting across diverse operating systems.
• Strong systems engineering foundation: deep networking knowledge, experience managing Linux infrastructure, and the ability to design and implement solutions from the ground up rather than solely administer existing systems.
• Demonstrated automation and software skills in Python for building custom tooling, services, and CI/CD workflows, with strong system design thinking to evaluate second- and third-order effects and build resilient systems.
• Comfortable reading and reviewing Go code, particularly in the context of understanding upstream changes in projects.
• Experience with dynamic routing (eBGP, iBGP, OSPF, SD-WAN), network segmentation, logging/alerting with SIEMs, and zero-trust architectures.
• Ability to diagnose low-level connectivity and performance issues and to work effectively with stakeholders and end users.
• Self-starter with excellent time-management, communication (written and verbal), and collaboration skills; mid-career professional who has successfully owned similar infrastructure or remote-access initiatives.

ADDITIONAL REQUIREMENTS

• This role requires you to be onsite. Hybrid or remote work will not be considered.
• Willingness to work extended hours and weekends as needed.

COMPENSATION AND BENEFITS

Pay Range: Level 3: $165,000.0
