• Architect scalable distributed systems to support real-time workloads over petabytes of heterogeneous telemetry data.
• Build live evaluation pipelines, automated scoring systems, and benchmarks to measure and drive AI performance.
• Collaborate with AI engineers and scientists to integrate AI-driven insights and solutions into backend systems.
• Monitor, optimize, and scale backend services to handle high volumes of data while ensuring low-latency performance.

Requirements

• Strong system design skills for distributed systems.
• Proven production-scale software engineering experience.
• Experience with LLM-based applications and/or multi-agent systems.
• Strong data modeling skills and a track record of writing clean, maintainable code.
