In our team, you will design, validate, and maintain secure, high-performance network infrastructures supporting ground systems for space missions. You will also develop and implement network configurations, support system integration and validation, and work closely with multidisciplinary teams to ensure operational readiness.
Your main tasks in the areas of responsibility described will be:
NetworkIntegration & Validation:
1. Design and implement Layer 2/3 network configurations including VLAN segmentation, IP subnetting, routing protocols (OSPF, BGP), and multicast distribution.
2. Execute end-to-end network validation procedures including latency profiling, throughput benchmarking, failover simulation, and packet loss analysis using tools like iperf, Wireshark, and PingPlotter.
3. Support AIV campaigns by provisioning and validating connectivity across isolated testbeds, operational LANs, and WAN links.
️Troubleshooting & Incident Response:
4. Perform deep packet inspection and root cause analysis across the OSI stack to resolve connectivity issues, protocol mismatches, and performance bottlenecks.
5. Apply security patches, reconfigure firewall rules (NAT, ACLs), and mitigate vulnerabilities such as rogue DHCP servers, ARP spoofing, or misconfigured routing.
Network Architecture & Documentation:
6. Maintain detailed network topology diagrams, IPAM databases, and configuration repositories using tools like NetBox, RANCID, or Git.
7. Document test plans, change requests, and rollback procedures in compliance with configuration management policies.
Monitoring & Automation:
8. Deploy and tune SNMP-based monitoring systems (, Zabbix, PRTG, Nagios) and integrate with log aggregation platforms (, ELK Stack, Splunk).
9. Develop scripts and playbooks using Python, Ansible, or Netmiko to automate repetitive tasks and enforce configuration consistency.
️Change Management & Risk Assessment:
10. Evaluate the impact of network changes (, hardware upgrades, topology redesigns, firmware updates) and provide mitigation strategies to ensure service continuity.
11. Simulate production-like environments to validate new configurations before deployment.
