Company mission
To build the decision infrastructure that helps the world take on more risk with confidence.
Role
Who you are
- 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
- If you're energised by complexity and motivated to grow, we encourage you to apply and join our global team
What the job involves
- At hx, AI is central to how we build software and make decisions across the company. From large-scale document intelligence to a domain-specific AI peer-programmer used by actuaries and underwriters, hx is redefining how the insurance industry uses generative AI in production
- 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
- Working closely with product and research teams, we turn fast-moving experimentation into reliable, cost-efficient, and developer-friendly production systems. Our success is measured in faster releases, stronger model performance in the real world, and AI products that customers can trust with critical decisions
- 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

Salary benchmarks
Our take
hyperexponential was created to provide modelling software to help people and businesses build, deploy and manage analytical models that work with small, sparse and fragmented datasets. Its goal is to make teams more agile, collaborate more deeply, and work more productively.
hyperexponential's pricing and data-driven decision-making software is built for the speciality and commercial insurance markets. The product has broad applications, but the company's initial focus is on speciality insurance, a sector the founders know well, having worked there for more than a decade.
The company's making a name for itself too, working with some of Europe's biggest insurers to transform how pricing decisions are made. And its newest launch, hx AI, blends powerful AI with its core platform to help insurers build smarter models, faster. It's a strong signal that hyperexponential is not just growing, but ready to lead the way.
