Member of Technical Staff - AI Engineer

NeoSigma is a product-driven research lab building the intelligence layer that helps close the feedback loop between your customers, products, and AI systems. They are seeking a Research Engineer to build intelligent systems that learn from real-world usage, working across LLMs and production AI systems.

Responsibilities:

• Build SOTA agentic pipelines that mine production traces for failures mining, triaging, evaluations, and optimizations
• Design and implement large-scale data processing systems that turn production agent traces into signal for evaluation and optimization
• Design and run optimization loops that convert evaluation signal into measurable gains in agent behavior
• Own the cost and latency profile of our ML systems as trace volume and customer count scale
• Push novel evaluation and post-training research into production within weeks
