Network Engineer Needed: Debug Docker Networking, Stubby, & VPN Stack
Budget: $50 – $0 USD
We are seeking an experienced Linux/Network Engineer to troubleshoot and resolve a networking bug in our privacy stack. Our system runs on a Ruby on Rails platform, utilizing Dockerized services including Stubby and VPN protocols. We have multiple units successfully running in production, but a recent development has caused connectivity instability in a subset of clients.
Seeking additional network expertise to diagnose the root cause—whether it is a Docker networking conflict, an iptables misconfiguration, or an upstream TLS handshake failure.
Required Skills
• Deep Linux Networking: iptables , ip route , systemd-resolved, /etc/resolv.conf management.
• Troubleshooting: Experience with command-line debugging tools ( tcpdump , netstat , openssl ).
Helpful Skills, but not required:
• Devops skills - Ansible and Docker
• Ruby on Rails
• Encryption/Privacy Protocols
• Experience with mainland China networks a plus
Potential for long-term maintenance role. Please provide rough estimate for initial diagnosis, followed by final fix/root-cause analysis.
