Responsibilities
Design and implement network segmentation strategies, differentiating between operational and transactional networks, as well as segmenting by business tier for optimal performance and security.
Ensure clear and up-to-date documentation of network topologies, including logical and physical layouts, highlighting critical components, failover paths, and redundancy strategies.
Configure and manage ACLs to ensure the security of data and resources across the network, enforcing appropriate access controls and minimizing unauthorized access.
Maintain detailed records of network capacity, including bandwidth, latency, and throughput expectations for both current and future needs.
Administer and update management tools and software, ensuring that they are running the latest versions and are integrated into the network monitoring solution.
Ensure audit logs are regularly reviewed, securely stored, and easily accessible for compliance, troubleshooting, and security assessments.
Spanning Tree Protocols: Manage and configure RSTP (Rapid Spanning Tree Protocol) and MST (Multiple Spanning Tree) to ensure optimal network convergence and fault tolerance.
Document and maintain network convergence procedures to reduce Time to Detection and Time to Convergence in case of network failures.
Circuit Breakers: Implement automated circuit breakers for rapid detection and isolation of network issues, ensuring minimal impact on users and systems.
Ensure the network design includes dual links, alternate routes, and high availability configurations to mitigate any single points of failure (SPOFs).
Develop and document failover strategies to guarantee that critical systems remain online during outages, with clearly defined failover processes and minimal latency during failover events.
Conduct thorough assessments of the network to identify SPOFs such as single gateways, routers, switches, and NICs. Implement redundancy to remove these risks and ensure continuous availability.
Conduct simulations of network failures (link, device, or circuit) to test the impact on the system and identify areas for improvement.
Performance Under Failure: Measure latency, throughput, and bandwidth degradation during failure simulations, and assess packet loss scenarios, including high-stress situations such as Syn Flood and DDoS attacks.
Design and implement various network topologies, including star, bus, ring, and mesh, depending on business needs and the size of the infrastructure.
Manage on-premises, cloud, and hybrid network environments, ensuring seamless integration and optimal performance across various infrastructures.
Firewall & Subnet Management: Configure and maintain firewalls, subnets, and ACLs to secure network resources and prevent unauthorized access.
Network Monitoring & Diagnostics: Implement and manage network monitoring solutions, including performance monitoring and alerting systems, to proactively identify and address network issues.

Required
10-15 years of experience as a network engineer, with a proven track record in designing, configuring, and optimizing enterprise network infrastructures.
Strong knowledge of network protocols (TCP/IP, BGP, OSPF, VLANs, etc.).
Hands-on experience with Spanning Tree Protocols (RSTP, MST).
Expertise in network segmentation, ACLs, subnets, and firewall configurations.
Experience with network monitoring tools (e.g., SolarWinds, Wireshark, PRTG).
Familiarity with hybrid cloud environments (AWS, Azure) and cloud network architecture.
Experience in DDoS mitigation, load balancing, and high-availability configurations.
Proficient in using network automation tools (e.g., Ansible, Puppet, Chef) to streamline configuration management and troubleshooting.
Proven ability to design and implement high-availability network architectures with failover and redundant links.
Knowledge of network security best practices, including securing network access with ACLs, firewalls, and other security measures.
Experience with capacity management and scaling to meet growing business needs.
Preferred
Bachelor's degree in Computer Science, or a related field is preferred. Relevant work experience may be considered in lieu of a degree.
