Network Engineering Jobs

I run a busy schedule of trade shows in the Orlando area and need a reliable technician I can call on whenever we roll into town. Your main focus will be keeping our registration operation online and headache-free. What the work looks like • Pre-show bench testing of network gear, computer terminals, and our proprietary registration software/hardware in the warehouse or hotel ballroom. • On-site setup: cabling, router/switch configuration, imaging or re-imaging laptops/kiosks, and confirming every station can reach the show database before doors open. • Live-event coverage: rapid troubleshooting of network drops, frozen terminals, printer jams, and any software hiccups while attendees check in. • Post-show teardown, packing, and fault reporting. Typical gear y...

We are looking for an experienced Network Engineer / ISP Engineer with strong MikroTik RouterOS v7 and BGP experience. However, we need assistance with: Proper dual-upstream BGP design Local/Global routing optimization Prefix propagation validation Return routing troubleshooting Public IP routing without NAT/masquerade Traffic engineering and failover Route filtering best practices MikroTik RouterOS v7 BGP optimization

I’m facing recurring connectivity and performance issues across my small-office network and need a technician who focuses specifically on network support to step in quickly. The job is entirely remote: you’ll connect to my environment, pinpoint the root cause of dropped connections and sluggish speeds, and then apply a clean, documented fix. Here’s what I expect: • A thorough diagnostic session covering routers, switches, and current cabling layout (where traceable from afar). • Implementation of configuration changes or firmware updates that restore stable throughput. • A concise report outlining the problem, the steps you took, and any preventive recommendations. Experience with common SMB hardware (Cisco, Ubiquiti, MikroTik, or similar) and standa...

A UniFi Dream Machine Pro must accept WireGuard connections placing users into specific VLANs, maintaining the current zone-based firewall configuration. Requirements: • Check current WireGuard configuration on the UDM Pro (firmware 5.0.15, network 10.3.58). • Check the current WireGuard .conf file for errors. • Ensure connections land in the designated VLANs; cross-VLAN routing is already in place. • Apply balanced encryption settings to keep security high without crippling speed. • Check Zone based firewall rules for future security, with no unexpected open ports. • Provide a brief, step-by-step hand-off document. Test by connecting devices and confirm internal services are accessible on the specified VLANs.

NS-3 Network Simulation Task Project Overview I am looking for assistance with a small networking task using NS-3 which can be downloaded via: (ns-allinone-3.35 version). The goal of this task is to work with the provided simulation example and modify it to evaluate network performance metrics. The task focuses on understanding how NS-3 can be used for analyzing communication networks that include both wired and wireless connections. Required Tasks The selected freelancer should: • Modify the source file in NS-3. • Calculate and display the following performance metrics at the end of the simulation: o End-to-end delay o Throughput • Update the client node behavior so it sends more than one packet during the simulation. • Use the MakeCallback() function within th...

I am standing up a full, multi-tenant Network Operations Center that must handle both L1 monitoring and L2 operational tasks for our managed-service customers. From day one the stack has to scale, isolate tenants cleanly, and integrate into our existing ITSM workflow. Monitoring & Dashboards • Monitoring platform: Zabbix is the preferred core. • Dashboards: must surface real-time data for each tenant with role-based visibility, SLA counters, and clean hand-off to ticketing. • Advanced alerting comes in during Phase 2, tied to Cisco ecosystem metrics. Log Management Centralized logging plus log correlation and analysis are required so we can move straight from an alert to actionable insight without hopping between tools. Phased Build Phase 0 (2-3 w...

I have two Siemens Ruggedcom models—RST2228 and RCM30—that must be fully configured for an industrial automation backbone. The switches will sit in front of our SCADA systems, so reliability and deterministic performance are non-negotiable. Core requirements • Build and document the complete configuration from factory default to final running state. • Implement multiple VLANs that logically separate control traffic, engineering access, and diagnostics. I will provide the exact VLAN IDs and naming scheme once we begin. • Establish all necessary trunk and access ports, making sure tagging is consistent across both models. • Verify forwarding, redundancy (RSTP or MRP), and security settings that are best practice for a harsh-environment plant floor. ...

Deterministic State Testing: Develop a mechanism to bypass runtime RNG (Random Number Generation) to ensure consistent, predictable outputs during diagnostic runs. The system must allow testers to force specific event outcomes for reliability testing. A toggle mechanism (hotkey) is required to switch between standard and deterministic modes instantly. Frontend Data Binding Diagnostics: Create a routine to locally simulate elevated data values on the application's user interface. The goal is to verify how the frontend handles rendering outlier values without impacting the core application stability or causing asynchronous errors. Traffic Shaping & Payload Normalization (Crucial): Design a network layer filter to analyze outgoing telemetry/action data. The module must be capable of ...
