Description
Summary We are looking for an experienced Backend/DevOps Engineer to build and deploy a high-performance, automated multi-tenant streaming infrastructure. The goal is to provision access to a white-labeled Stremio-based client (Nuvio) for 50+ active concurrent users while ensuring zero buffering and absolute bypass of single-IP debrid restrictions via an unthrottled media proxy cluster. You will be linking a frontend billing gateway (FOSSBilling) to a media management layer (AIOStreams) and a high-throughput proxy server (MediaFlow Proxy Light in Rust). Key Responsibilities: Infrastructure Deployment: Set up and configure mediaflow-proxy-light (Rust build) and AIOStreams via Docker/Docker-Compose on a 1 Gbps dedicated Linux VPS (Ubuntu/Debian). Optimize network sockets (sysctl tuning) to handle concurrent multi-user segment chunk requests without latency. Billing & Provisioning Automation: Write a custom Server Manager PHP module for FOSSBilling (library/Server/Manager/) that interacts with the AIOStreams Admin API (/api/admin/users/*) to automate user lifecycle states: creation, token provisioning, account suspension, resumption, and permanent deletion. APK Modification / Authentication Setup: Modify the setup/addon layer of a custom Nuvio (Stremio-based) front-end application to replace the default URL manifest input with a clean, user-friendly Username/Password login screen. This screen must dynamically compile the underlying manifest path (https://yourdomain.com/api/(https://yourdomain.com/api/)username/password/manifest.json) in the background. Traffic & Bandwidth Engineering: Configure strict Stream Expression Language (SEL) rules inside the aggregator to optimize bandwidth (enforce 1080p H.265/HEVC profiles, filter out heavy 4K/Remux files, and apply strict video asset file-size ceilings). Set up load-balancing rotation across a pool of 5+ Real-Debrid accounts. Required Technical Skills & Experience: Languages: Strong proficiency in PHP (for FOSSBilling custom server modules), Rust/Python container environments, and Bash/Shell scripting. Containerization & DevOps: Docker, Docker-Compose, Linux server administration, reverse proxy routing (Nginx/Traefik), and SSL certificate orchestration (Let's Encrypt). Streaming & Video Architecture: Familiarity with HLS (.m3u8, .ts), MPEG-DASH, Stremio addon protocol ecosystem, AIOStreams, and MediaFlow Proxy network logic. Security Mindset: Understanding of secure API authentication, token handling, and how to harden a compiled client build to prevent network packet sniffing or exposure of private API credentials. Project Type: One-time project with high potential for long-term monthly infrastructure maintenance and scaling support. Application Requirement: When applying, please briefly describe your past experience with video streaming proxies, Stremio addon architectures, or building custom automation plug-ins for billing platforms like FOSSBilling, WHMCS, or Blesta. Applications using generic copy-paste templates will be immediately declined.
