Job description

Experienced Network Engineer for NYC WISP (MikroTik Routing Expert)

We are a fast-growing Wireless Internet Service Provider (WISP) based in New York City, seeking a Network Engineerwith at least 6 years of experience, specializing in MikroTik routing and network management. This is a full-time, on-site role, and candidates must be local to NYC.

Key ResponsibilitiesAdvanced Routing Protocols (OSPF, BGP, MPLS) for Scalability and Reliability

• OSPF (Open Shortest Path First):
• Design and implement multi-area OSPF networks to ensure efficient routing and rapid convergence.
• Optimize network performance by creating hierarchical OSPF architectures with backbone areas and edge areas.
• Maintain and troubleshoot OSPF adjacencies, route redistribution, and cost balancing for optimal traffic distribution.
• BGP (Border Gateway Protocol):
• Configure and manage BGP to handle multi-homed connections with upstream providers, ensuring redundancy and traffic balancing.
• Implement advanced BGP features such as route aggregation, communities, and AS-path filtering for efficient traffic management.
• Ensure high availability by integrating BGP with failover mechanisms and backup links.
• MPLS (Multiprotocol Label Switching):
• Deploy MPLS for streamlined packet forwarding and improved QoS across the WISP network.
• Design and configure MPLS VPNs for isolating traffic between enterprise and residential customers.
• Implement MPLS Traffic Engineering (TE) to optimize bandwidth usage and guarantee performance for high-priority traffic.
• Policy-Based Routing (PBR):
• Implement custom routing policies to direct traffic based on specific parameters such as source/destination IP, traffic type, or VLAN.
• Configure PBR to prioritize critical applications, ensuring low latency for services like VoIP and streaming.
• Redundancy and Failover:
• Design and manage high-availability solutions, including redundant routing paths and automatic failover configurations.
• Utilize VRRP (Virtual Router Redundancy Protocol) to maintain seamless network operations during router failures.

Core Network Design and Maintenance

• Architect and maintain a robust and scalable WISP backbone using PtP and PtMP wireless technologies.
• Oversee the integration and interoperability of MikroTik and Ubiquiti equipment in a hybrid network environment.
• Manage core switches, routers, and firewalls to ensure optimal performance and security.

IP Address Management and Provisioning

• Plan and implement efficient IP subnetting schemes for customer isolation and network scalability.
• Automate IP address provisioning and RADIUS-based authentication for seamless customer onboarding.

Traffic Management and QoS

• Configure MikroTik Queue Trees for precise traffic shaping and bandwidth allocation.
• Ensure high-priority traffic (e.g., VoIP, video streaming) receives guaranteed bandwidth through QoS policies.

Monitoring and Troubleshooting

• Use tools like Zabbix, The Dude, and PRTG for real-time network monitoring and diagnostics.
• Troubleshoot complex routing issues, identify bottlenecks, and implement performance improvements.
• Maintain comprehensive documentation of network configurations, routing policies, and failover mechanisms.

Security and Compliance

• Harden network security by implementing MikroTik firewalls, DDoS protection, and access control policies.
• Regularly update firmware and software across all devices to maintain compliance with industry standards.

Requirements

• Experience:
• Minimum 6 years of hands-on experience with MikroTik RouterOS and advanced routing protocols.
• Proven expertise in configuring and managing OSPF, BGP, and MPLS for scalable and reliable networks.
• Strong background in designing and managing WISP networks, including PtP and PtMP systems.
• Technical Expertise:
• Advanced knowledge of VLAN management, QoS, and traffic shaping.
• Proficiency with RADIUS-based provisioning and network automation.
• Familiarity with Ubiquiti hardware and its integration with MikroTik infrastructure.
• Physical and Operational Requirements:
• Comfortable lifting up to 40 lbs and using power tools for installations and maintenance.
• Ability to drive a commercial van and work on-site as needed.
• Must be based in NYC with a valid NYC driver’s license.
• Professional Skills:
• Strong analytical and problem-solving abilities.
• Excellent communication skills for collaboration and customer interactions.
• Proven ability to work under pressure in a fast-paced environment.
