Data Engineer / Network Traffic Analysis £500 - £550 per day Inside IR35 6-Month Contract Hybrid - 2 Days per Week in Islington, London

83zero is recruiting for a Data Engineer / Network Traffic Analysis specialist to join a highly technical team working with large volumes of network and traffic data.

This is not a traditional Data Engineering position. We are looking for someone who combines strong networking knowledge with hands‑on packet and traffic analysis
, particularly using Wireshark, PCAP and tcpdump
.

You will be working at packet and protocol level, capturing, investigating and analysing network traffic before turning that information into usable data for further processing and analysis.

• Capturing and analysing network traffic using Wireshark, PCAP and tcpdump

• Investigating network behaviour at packet and protocol level

• Analysing TCP/IP, DNS, HTTP/HTTPS, ports, protocols and traffic flows

• Filtering packet captures to identify patterns, anomalies and potential issues

• Troubleshooting network connectivity, latency, routing and protocol issues

• Extracting, transforming and analysing technical/network data

• Using Python and SQL to work with network, telemetry or data sets

• Working alongside data, networking and security teams

• Supporting cloud‑based data and network environments

You should have strong hands‑on experience across:

• Wireshark

• PCAP / packet capture

• Network traffic analysis

• Network sniffing

• tcpdump

• TCP/IP

• DNS

• HTTP / HTTPS

• Network protocols and troubleshooting

• Python and/or SQL

Experience with
GCP / Google Cloud
, Big Query, Pub/Sub or Dataflow would be beneficial, but it is not essential. The priority is genuine hands‑on network traffic and packet analysis experience.
