At hyperexponential, we’re building the AI-powered platform that enables the world’s most critical decisions in a $7 trillion industry, which risks to take, and how to price them. The AI Platform team provides the platform that makes all of this possible. We design, build, and operate the shared systems that allow teams to train, deploy, evaluate, and monitor AI safely at scale — including model serving, data pipelines, observability, deployment automation, and compute orchestration.
Job Responsibility:
Designing and operating scalable AI infrastructure for LLM inference, prompt management, and evaluation pipelines, supporting billions in premium flow
Building self-service tools, SDKs, and APIs that empower product teams to move from prototype to production 30% faster
Instrumenting production AI/ML workloads with standardised logging, tracing, and evaluation metrics, increasing observability coverage to 100% of deployed models
Implementing intelligent routing, caching, and provider optimisation via the LLM gateway, reducing AI compute costs by up to 25%
Driving adoption of shared platform services (LLM gateway, evaluation frameworks, monitoring) to replace bespoke solutions, increasing platform adoption across new AI features
Championing developer experience by delivering comprehensive documentation and responsive support, resulting in higher internal customer satisfaction
Requirements:
Built and deployed production AI infrastructure that scaled to support enterprise-grade reliability and observability
Delivered self-service tools or APIs that enabled multiple product teams to accelerate their AI/ML development cycles
Implemented evaluation frameworks, A/B testing infrastructure, or monitoring solutions that measured and improved model performance, latency, cost, and quality in production
Led initiatives to reduce AI compute costs through optimisation strategies such as intelligent routing or caching
Successfully migrated teams from bespoke AI solutions to shared platform services, driving measurable adoption
Prioritised and improved developer experience through documentation, support, or workflow enhancements
