网络工程 Jobs

Hardware networking .....Detail-oriented IT professional with a certification in Hardware and Networking. Skilled in PC assembling, OS installation, and basic LAN/WAN troubleshooting. Eager to leverage foundational knowledge of TCP/IP, routers, and switches to support daily IT operations and resolve end-user issues efficiently.

Project Overview: We are looking for an expert, senior-level Enterprise Network Architect/Engineer to lead a multi-vendor project deployment, design review, and the production of final As-Built documentation. Our current infrastructure environment requires deep architecture alignment across modern software-defined networking (SDN), zero-trust security components, and centralized management fabrics. This is a critical infrastructure project requiring strict adherence to security compliance, high availability, and optimal traffic routing principles. Scope of Work: 1. Architecture & Design Review -Conduct a thorough review of the current network topologies, security zones, and high-level designs. -Identify potential bottlenecks, asymmetrical routing risks, and security gaps before act...

I need a complete surveillance system set up that covers both my indoor living areas and the outside perimeter. The priority is seamless remote access, so I can check live feeds and recordings through a reliable mobile app whether I’m on-site or away. You’ll be responsible for: • Advising on hardware that pairs well with user-friendly remote-view apps • Professionally mounting and wiring the cameras (indoor and weather-proof outdoor units) • Configuring the network, storage, and app integration so every camera streams correctly to my phone and tablet • Testing the entire system with me to confirm each view is clear and accessible before sign-off Experience with multi-camera IP setups, robust Wi-Fi/LAN configuration, and secure remote login is e...

I need an experienced Cat6 installer to complete a focused cabling job in a school where the new runs will support upgraded internet connectivity. The scope is tightly defined: pull and route Cat6, then handle all patching and precise punch-down terminations. No other services are required on this engagement. Because learning spaces can’t stay offline for long, you must be comfortable working around class schedules and following basic safety protocols in an active campus environment. I will supply the cable, patch panels, and keystone jacks on site; you bring your own termination tools, tester (Fluke or comparable), and ladder if needed. Deliverables • All Cat6 drops routed, dressed, and labeled • Patch panels fully punched down with clean, colour-correct pairs •...

My site-to-site IPsec tunnel was built following best-practice guides, yet the link keeps dropping for reasons I can’t see. The firewall on my side is an Opnsense appliance, and each time the tunnel fails the logs simply show that the connection drops intermittently without any clear error codes. I may have tweaked something recently, but I’m honestly not sure which setting—so I need a fresh, expert pair of eyes. You should be comfortable working with Opnsense and, ideally, have experience on Checkpoint or other enterprise firewalls so you can think through the usual Phase 1 / Phase 2, NAT-T, lifetime, and crypto-profile culprits quickly. I can give you full access to the existing configuration, live logs, and packet captures through a remote session. The job is compl...

Configure HG8120C XPON ONU to use LAN 1 as WAN port instead of GPON, to access Internet & VoIP Server on LAN port 2 in Routing mode bet Port1 & Port 2.

I am working with an Exablaze Exanic card in an OLTP environment and I am seeing end-to-end send latency hovering around 2–3 ms with the function encapsulating all the below functions costing about 1 us. All traffic is generated through the exasock API, with calls in roughly this order: exasock_tcp_build_header → exasock_tcp_set_length → exasock_tcp_calc_checksum → exanic_transmit_frame → exasock_tcp_send_advance My sole objective is to drive that latency down as far as the hardware allows. If you have hands-on experience squeezing microseconds out of Exanic-based pipelines—whether through driver parameters, FPGA firmware tweaks, user-space memory mapping, or smarter batching in the exasock code path—I would like your help. What I can provide ...

A batch of new switches is arriving at our premise and I need reliable smart-hands assistance to swap them in without interrupting service. The job is strictly on-site and centres on a wired network setup: unplug the legacy hardware, mount and cable the replacement devices, power-test, and clear the rack of the retired units for collection. You will be guided in real time by a remote engineer who will confirm port assignments and link-light checks. No software configuration is required—just precise physical work and the ability to follow clear, step-by-step instructions while keeping everything tidy and properly labelled. Deliverables • New devices physically installed, patched and powered on • Old devices removed, boxed and labelled for return • Photogr...

I need 4-6 TVs installed in a large room to broadcast the World Cup match. Requirements: - Mount some TVs and place others on stands - Ensure all TVs are properly connected and configured for optimal viewing Ideal skills and experience: - Experience in TV installation and setup - Ability to work in large spaces - Attention to detail for a professional finish Please include relevant experience in your application.

I need a full CAT6 network rolled out—more than 50 drops in total. The scope covers pulling and dressing the cable, installing and terminating I/O wall boxes, fitting patch panels, mounting the switches, and finishing with clear, consistent labeling and tagging. The work will span several environments: standard office areas, a data-center room, and a few residential-style spaces, so the approach has to remain tidy, code-compliant, and adaptable. All terminations must be tested with a Fluke (or equivalent) and documented. I will provide floor plans and port-numbering schemes on site; the finished labels must match these exactly. Deliverables • Every CAT6 run properly routed, terminated, and certified • Patch panels dressed and connected to the mounted switches &bul...
