You will work extensively with Fortinet FortiGate firewalls and TippingPoint IPS platforms, supporting deployments, migrations, upgrades, replacements, and decommissions. Your work will help strengthen perimeter security, maintain network resilience, and minimize disruption across complex enterprise environments. Collaborating with engineering, architecture, operations, and project teams, you will translate technical designs into secure, reliable implementations. This is a remote opportunity for a highly skilled professional comfortable managing complex infrastructure changes and supporting scheduled maintenance windows, including nights and weekends when required.

Accountabilities

As an Implementation Engineer, you will take ownership of enterprise perimeter security implementations and contribute to the stability, security, and modernization of network infrastructure. Your responsibilities will include:

• Build, configure, deploy, upgrade, and support Fortinet FortiGate firewalls and TippingPoint IPS platforms in enterprise environments.

• Lead firewall and IDS/IPS lifecycle initiatives, including hardware and software refreshes, migrations, upgrades, replacements, capacity expansions, and decommissions.

• Plan and execute implementation and maintenance activities, including pre-implementation checks, validation, post-installation support, and back-out planning.

• Troubleshoot complex network and security issues involving connectivity, routing, traffic inspection, firewall policies, platform performance, and configurations.

• Develop detailed implementation procedures, deployment guides, technical documentation, and low-level configuration specifications.

• Evaluate complex technical requests and translate approved architecture and designs into successful implementations.

• Collaborate with engineering, operations, architecture, and project teams to identify and mitigate technical risks before implementation.

• Support vulnerability remediation initiatives and other activities aimed at reducing operational and security risks.

• Maintain accurate technical records, asset information, inventory, and project closeout documentation.

• Identify and implement opportunities to improve service delivery through automation, standardization, and process optimization.

• Participate in scheduled maintenance windows, including nights and weekends when required.

Requirements

The ideal candidate brings extensive hands-on firewall implementation experience, strong enterprise networking knowledge, and the ability to execute complex infrastructure changes in production environments. Candidates should demonstrate:

• A bachelor's degree or equivalent professional experience.

• At least 8 years of IT experience working with firewall solutions, including hands-on experience building firewalls from scratch.

• Strong practical experience with Fortinet FortiGate firewalls and TippingPoint IPS platforms.

• Experience managing FortiOS and TippingPoint software upgrades and platform lifecycles.

• A strong understanding of enterprise networking fundamentals, including routing, switching, Layer 2 and Layer 3 protocols, multicast, and traffic flows.

• Excellent troubleshooting and problem-solving skills across network and security infrastructure.

• Experience supporting production implementations, maintenance activities, and technical incidents.

• Ability to create, maintain, and communicate detailed technical implementation documentation.

• Strong communication skills, including the ability to explain technical risks, issues, implementation status, and remediation plans clearly.

• Excellent organizational skills and attention to detail.

• Flexibility to support scheduled maintenance windows, including nights and weekends as needed.

Nice to Have:

• Experience with Python, Shell scripting, JSON, APIs, or similar technologies used for automation and operational tooling.

• A track record of improving processes through automation, standardization, or operational optimization.

• Experience working in large-scale enterprise environments with multiple concurrent projects and strict change-management procedures.

• Knowledge of enterprise DMZ architectures, perimeter security controls, and supporting network infrastructure.

• Familiarity with Cisco routing and switching technologies.

• Strong understanding of networked applications and services, including HTTP/HTTPS, SSH, BGP, SNMP, multicast, DHCP relay, and Anycast.

Benefits

• Full-time employment.

• Remote work arrangement within the United States.

• Opportunity to lead critical enterprise perimeter security implementations.

• Exposure to complex enterprise cybersecurity infrastructure and modernization initiatives.

• Collaboration with engineering, architecture, operations, and project teams.

• Opportunity to contribute to security improvements, infrastructure resilience, and operational optimization.
