About hyperexponential
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. These are the decisions that shape real-world outcomes: whether rockets successfully launch into space, autonomous vehicles make it to market, or communities recover after major storms.
Until now, insurance has been making billion-dollar decisions using outdated tools.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 - helping them move faster, act smarter, and take on more risk with confidence.
Backed by a16z, Highland Europe, and Battery Ventures, we’re scaling globally - already trusted by nearly 50 of the world’s largest insurers, with zero churn and billions in premiums flowing through hx.
What began as a single product in one market has rapidly evolved into a multi-product, multi-territory platform powering every stage of pricing and underwriting. AI is at the core of what we do - from building the world’s first domain-specific AI peer programmer for insurance (think GitHub Copilot with a PhD in actuarial science) to shaping agentic workflows that reinvent how this industry operates.
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 engineered to endure.
If that sounds like you, join us in building what comes next.
About our Pricing & Innovation Team
Most actuarial roles are tied to a single portfolio in a single organisation. At hyperexponential, you’ll apply your expertise across many insurers, seeing first-hand how the most advanced players are transforming their pricing and shaping what best practice looks like for the wider market.
As a Senior Pricing Actuary in our Pricing & Innovation team, you’ll sit at the centre of how hx defines and delivers next-generation pricing. This isn’t a back-office actuarial role. You’ll partner directly with underwriters, actuaries, and product leaders-both inside hx and at our clients - to understand their challenges, design solutions, and cast a vision for how pricing and underwriting can evolve.
The Pricing & Innovation team bridges actuarial depth with technical delivery and product insight. In this role, you’ll bring credibility in pricing, as well as curiosity about new methods, data, and technology, helping our clients adopt AI-enabled workflows and portfolio intelligence as part of their day-to-day practice.
hx itself is evolving rapidly - expanding into new lines, geographies, and use cases, with AI and automation redefining what’s possible. Your job is to help clients keep pace with that evolution, while feeding their insights back into our platform to ensure hyperexponential stays at the leading edge of insurance pricing.
Think of it as a hybrid between in-house and consulting: you’ll need the technical expertise to engage credibly with senior actuaries and CUOs, but also the consulting mindset to guide transformations, influence stakeholders, and shape how entire organisations adopt change.
What you’ll be doing
Act as a subject matter expert in pricing across commercial, specialty, and reinsurance - joining complex client and sales conversations, running best-practice workshops, and representing hx at industry forums.
Partner with senior stakeholders (Chief Actuaries, CUOs, Heads of Pricing) as a trusted advisor - guiding strategic conversations on pricing transformation, workflows, and portfolio strategy, and stepping in to resolve challenges with “amber-red” accounts.
Support customers through their transformation journeys - helping deploy new models, re-engineer workflows, and embed modern pricing processes, while building practical assets (reference models, reporting pipelines, workflow enhancements) that accelerate value from hx Renew.
Feed back client and market insights into hx - informing our product roadmap and ensuring we prioritise solutions that matter most to the business, not just technically.
Contribute to innovation projects - exploring new methods, data sources, or AI applications that reshape pricing and underwriting.
What you’ll need to have done
Be a newly or recently qualified actuary with pricing experience in commercial, specialty, or reinsurance markets (reinsurance exposure is a plus, but not essential).
Contributed to the development or enhancement of pricing models, with some experience of how models are applied in live underwriting.
Shown the ability to work effectively with stakeholders—whether peers or senior colleagues—by explaining technical work clearly and supporting decisions that go beyond the model.
Demonstrated an interest in the commercial impact of actuarial work, whether through project experience, client-facing exposure, or transformation initiatives.
Worked hands-on with actuarial and analytical tools (e.g. R, Python, data pipelines), and comfortable discussing methods, assumptions, and trade-offs with rigour.
You’re unlikely to thrive here if
You prefer established processes and aren’t motivated to explore how AI, automation, or portfolio intelligence could reshape pricing.
You’d rather focus narrowly on model-building than engage clients in shaping their wider pricing transformation.
You need rigid playbooks and step-by-step instructions, rather than the chance to help define what “best practice” looks like for the market.
If reading our Culture Doc 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 feel excited by the opportunity to grow with us.
