Expert System Engineer – Charging & Usage Platforms

Responsibilities

• Design and evolve large ‑ scale charging, usage rating, and network data processing platforms that support real ‑ time and high ‑ volume monetization of network traffic.
• Architect scalable, high ‑ performance systems that ingest, process, rate, and distribute usage data across complex BSS and downstream ecosystems.
• Translate charging and usage business requirements into end ‑ to ‑ end technical designs, ensuring accuracy, performance, and reliability at scale.
• Serve as the primary technical owner for charging and usage initiatives, accountable for architecture decisions, roadmap execution, and delivery outcomes.
• Lead cross ‑ functional design efforts involving network systems, mediation, rating engines, downstream billing, and data consumers.
• Partner closely with vendors and internal platform teams to influence technical roadmaps and ensure seamless system integration.
• Conduct deep performance, latency, and reliability analysis, proactively identifying and resolving system bottlenecks and operational risks.
• Apply AI and advanced automation to improve rating accuracy, throughput, anomaly detection, and delivery efficiency.
• Maintain detailed system and architecture documentation, ensuring compliance with security, risk, and regulatory requirements.
• Act as a senior technical leader across domains, influencing broader platform decisions beyond charging and usage.

• Proven experience designing charging, usage, mediation, or network ‑ adjacent platforms in large ‑ scale enterprise environments.
• Strong system architecture skills spanning real ‑ time processing, high ‑ volume data pipelines, and distributed systems.
• Hands ‑ on experience translating business monetization requirements into resilient technical solutions.
• Ability to operate across network, platform, software, and cloud environments.
• Experience leading complex initiatives through technical influence rather than direct authority.
