About hyperexponential (hx)

At hyperexponential, we're building the agentic platform for end-to-end underwriting, helping insurers make the most critical decisions in a $7 trillion industry: which risks to take, and how to price them. These decisions shape real-world outcomes, from whether rockets launch into space and autonomous vehicles reach the market, to how communities recover after major storms.

Until now, insurers have been making billion-dollar decisions with outdated tools. We're changing that. Our platform brings together data, AI and human expertise to give insurers the fastest path from submission to decision, so they can move faster, act smarter and take on more risk with confidence.

Founded in 2017 by two former actuaries and backed by a16z, Highland Europe and Battery Ventures, we're scaling globally. We're already trusted by nearly 50 of the world's largest insurers, with zero churn and billions in premiums flowing through hx. In October we announced that hx has agreed to join Guidewire, one of the world's leading insurance technology companies, which gives what we're building an even bigger stage.

What began as pricing and model development is now an agentic platform for end-to-end underwriting. It takes insurers from submission and triage through to the underwriting decision, with AI working across the whole workflow and underwriters in control. Our newest product, hyperoperator, is a unified agent for underwriting work.

What makes hx different is the people who build it. Here, impact isn't tied to title or tenure. It's defined by the challenges you take on and the discipline you bring. Surrounded by peers who stretch you, you'll do the best, hardest work of your life in a company built to last.

About the Delivery Engineering team

Our Delivery Engineering team is a blend of engineers, actuaries, mathematicians and data scientists. We don't take on traditional transformation projects (we have brilliant partners for that). We specialise in the most difficult and interesting problems our customers face, where only a mix of technical depth, market expertise and hx platform knowledge will do.

Delivery Engineers are the experts' experts of the hx platform. You'll know it top to bottom, including its limits, which of them can be pushed, and every trick and shortcut along the way. You'll combine that with a growing knowledge of insurance technology to show customers the art of the possible and help shape cutting-edge tech, while working alongside some of the brightest, most ambitious people in tech and insurance.

You'll sit between building and customers: hands-on in Python, and working directly with the actuaries and underwriters who rely on the models you build.

What you'll be doing

• Delivering models on hx from build through to testing, iteration and handover, with guidance from Senior Delivery Engineers on scoping and approach.

• Building and maintaining production-grade Python models, applying modern engineering and modelling practices.

• Working directly with customer actuarial teams and internal stakeholders to solve complex modelling and coding problems.

• Contributing to quality through code review, testing and our best-practice model development guidance.

• Supporting Associate Delivery Engineers through pairing and feedback, while learning from the Senior Delivery Engineers around you.

• Using AI tools such as Claude to work faster, while making sure you can explain every line you ship.

• Looking for ways to improve our model development standards, tooling and ways of working.

What you'll need

• Shipped production-grade Python code, including testing, ideally in complex or data-heavy environments.

• Applied predictive modelling or advanced analytics in real-world settings (insurance or reinsurance exposure is a bonus, not a requirement).

• Worked through ambiguous problems with some guidance, bringing structure and seeing them through to good outcomes.

• Worked with non-technical stakeholders or customers, turning requirements into technical solutions, in English.

• Operated well in a high-trust, high-accountability environment, driving your own development and learning.

You're unlikely to thrive here if

• You prefer following detailed instructions to experimenting and finding your own approach.

• You're uncomfortable working directly with non-technical stakeholders to understand their challenges.

• You avoid ambiguous or open-ended problems where the answer isn't obvious.

If reading our Culture Document leaves you feeling neutral rather than energised, hx may not be the place where you'll do your best work. We're building something that asks for commitment and conviction, and we want you to be excited by the chance to grow with us.
