# Senior Live Streaming Engineer (Backend) - PT - Worldwide

- **Company:** Arc Full-time
- **Location:** United States (Remote available)
- **Experience:** Expert
- **Contract:** Temporary contract
- **Skills:** Application Programming Interfaces (APIs), Transcoding, WebRTC, Backend, Live Streaming, Front End Software Development, Video Streaming
- **Published:** September 3, 2026

## About the Role

* Proven experience building or scaling live video streaming platforms (not just consuming third-party streaming APIs)
 * Strong grasp of cost-efficient streaming architecture at scale (bandwidth, transcoding, CDN cost optimization)
 * Backend engineering proficiency
 * Comfortable working independently with early-stage founders who are non-technical, * Experience with large-concurrency, low-latency live streaming (social/live-streaming apps specifically, vs. VOD)
 * Prior work in emerging-market or cost-constrained infrastructure environments

## Description

Laivi is a live social streaming and creator economy app launching first in Mauritania with broader Africa/MENA ambitions. The MVP is built - backend, frontend, and virtual economy are functional - but the core live streaming layer has not yet been implemented. We're looking for a hands-on senior engineer to design and build a live streaming architecture that can scale to large concurrent audiences while keeping infrastructure costs low. This is a backend/infrastructure-focused role - no frontend work required.

What You'll Do

 * Design and implement a live streaming solution (ingest, transcoding, delivery/CDN) optimized for cost efficiency at scale
 * Evaluate and select streaming infrastructure/protocols (e.g. RTMP/WebRTC/HLS, self-hosted vs. managed) balancing cost against integration complexity
 * Integrate the streaming layer into the existing backend and virtual economy systems
 * Advise the founders on trade-offs between "easy but costly" and "harder to integrate but cost-efficient" solutions
 * Set technical direction for this first build phase, with potential to help shape future technical hires
