Company mission
To build the decision infrastructure that helps the world take on more risk with confidence.
Role
Who you are
- Built and deployed document extraction or document understanding systems that achieved measurable accuracy improvements in production environments
- Designed evaluation frameworks and datasets that enabled rigorous, repeatable measurement of model or pipeline performance
- Delivered data processing or transformation systems that were scalable, observable, and maintainable under real-world load
- Taken end-to-end ownership of complex AI features, from problem framing and experimentation through to production rollout and monitoring
- Collaborated across engineering, product, and customer-facing teams to ship solutions that solved real user problems rather than isolated research challenges
- Raised technical standards within your team by improving experimentation practices, documentation, or review processes beyond what was originally expected
- If you’re energised by complexity and motivated to grow, we encourage you to apply and join our global team
What the job involves
- AI is central to hx’s ambition to reinvent how insurers move from submission to decision. A significant part of that challenge begins before pricing even starts: transforming messy, inconsistent, insurance-specific documents into structured, reliable data that underwriters can trust. The AI Ingestion team owns this critical first mile
- Within this team, we build and scale document extraction and data transformation systems tailored to the complexity of specialty insurance. We operate at the intersection of large language models, classical document understanding techniques, evaluation-driven design, and production-grade infrastructure. Our outputs directly determine whether insurers can automate workflows across multiple lines of business with confidence
- As a Senior AI Engineer focused on Document Extraction, you will take ownership of solving high-stakes, insurance-specific extraction problems. Over the next 6 to 12 months, your mission will be to automate key data extraction and cleansing workflows across core specialty lines, hitting strict accuracy and consistency benchmarks while ensuring our systems are robust, observable, and built to scale
- Designed and delivered high-accuracy document extraction pipelines that automated key data capture across multiple specialty lines of business, enabling measurable reductions in manual processing during customer go-live
- Built and productionised data cleansing and manipulation capabilities within our ingestion system, improving consistency and reliability of downstream pricing inputs
- Defined and enforced rigorous evaluation-driven development practices, creating robust evaluation sets and benchmarks that guided model and pipeline improvements
- Improved our evaluation infrastructure for complex ingestion scenarios, enabling faster iteration cycles and clearer visibility into performance trade-offs
- Partnered directly with customers during go-live, diagnosing and resolving integration bottlenecks and production issues to ensure smooth technical rollouts
- Led technical deep-dives and brainstorming sessions to unblock complex extraction challenges, raising the bar on experimentation, knowledge sharing, and solution design across the team
Application process
- Initial call with Talent team (30 minutes)
- Manager Interview (60 minutes)
- Technical Assessment (e.g., code review, system design) (120 minutes)
- Values Interview with Tech Leadership (60 minutes)
- Offer
- If this opportunity resonates with you, we encourage you to apply or share it with your connections! Our dedicated talent team reviews all applications, and we promise to provide feedback regardless of the outcome
- Please note that background checks will be conducted as part of the hiring process to ensure compliance with our governance policies. We handle all background checks sensitively and in full compliance with relevant regulations
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.
