SYSTEMS DESIGNER

Job Description

1. System Architecture & Solution Design

- Participate in the overall system design of the OTT video platform – covering content ingestion, processing, delivery, playback, and operational monitoring.

- Produce system integration plans, interface specifications, deployment topologies, and capacity planning documents.

- Assess the legacy system capabilities and design data migration, service cut‑over, and rollback plans to ensure a seamless replacement.

2. Platform Component Integration & Optimisation

- Middleware – Integrate middleware services (authentication, session management, EPG, subscription/billing interfaces); optimise performance and disaster recovery capabilities.

- Origin – Deploy origin clusters; configure injection, packaging, encryption (DRM) workflows; optimise back‑to‑origin and storage policies.

- CDN – Interface with multi‑vendor CDNs or self‑built CDN; design content preheating, refresh, bandwidth scheduling, and failover logic.

- Network – Analyse operator network environments; optimise transport protocols, edge node distribution, and QoE metrics (time‑to‑first‑frame, rebuffering ratio).

- Multi‑Device Adaptation – Collaborate with STB, mobile, and web client teams to define unified access protocols and compatibility matrices.

3. System Integration & Verification

- Set up integration test environments; execute end‑to‑end functional, performance, disaster recovery, and security tests.

- Diagnose cross‑component complex issues (e.g., CDN back‑to‑origin timeout, middleware authentication bottlenecks, player compatibility defects) and produce root cause analysis reports.

4. Deployment & Operations Support

- Responsible for production environment deployment, automation script development (Ansible/Python), and monitoring/alerting system implementation (Prometheus/Grafana).

- Define SLA/SLO metrics and establish incident response mechanisms to support 6‑year long‑term operations.

- Participate in customer technical discussions and assist the delivery team in UAT acceptance.

Requirements

1. 5+ years of experience in video domain system design, integration, or operations. Experience with operator OTT or IPTV projects is preferred. Experience with Singapore or Southeast Asia projects is a strong plus.

2. Deep proficiency in the four core domains: Middleware, CDN, Origin, and Networking, with a systemic understanding of multi‑device clients.

3.Technical Stack

- Proficient in streaming protocols (HLS/DASH/CMAF) and container formats (TS/MP4).

- Familiar with Linux, containerisation (Docker/K8s), and common middleware (Nginx/Redis/MySQL).

- Proficient in at least one scripting language (Python/Shell) with ability to develop automation and monitoring tools.

4.Ability to independently identify end‑to‑end root causes from system logs, network packet captures, and performance metrics.

6.Fluent in English (written and spoken); able to produce high‑quality system design documents, test reports, and operations manuals.

7 Bachelor’s degree or above in Computer Science, Telecommunications, or a related field.
