Flexibility: We fully respect your full-time commitments. This role is highly asynchronous; work can be performed during evenings or weekends, provided that critical network alerts are addressed within a reasonable SLA. Core Responsibilities Infrastructure Replication: Take ownership of deploying our pre-compiled backend binary packages and Docker/K8s environments onto US cloud providers (AWS, DigitalOcean, Linode) and bare-metal bare servers. Network Maintenance & Optimization: Monitor the health, connectivity, and throughput of our US proxy tunnels (HTTP/SOCKS5). Optimize Linux kernel parameters (e.g., TCP congestion control/BBR, file descriptors) to minimize latency and packet loss. Incident Response & On-Call: Serve as the local point of contact for infrastructure-level anomalies, sudden node disconnections, or routing issues. Perform swift troubleshooting and live log diagnostics. Abuse & Security Monitoring: Monitor traffic anomalies to detect and mitigate malicious network activities (e.g., DDoS, financial fraud, unauthorized credential stuffing) to protect our IP pool reputation and ASN health. Cross-Border Alignment: Collaborate asynchronously with our Asia-based core dev team to sync system patches, configuration updates, and infrastructure alignment. ## Related Videos - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [WeAreDevelopers LIVE - Chrome for Sale?
