Senior Pricing Actuary in City of London

Overview

Join to apply for the Senior Pricing Actuary role at hyperexponential.

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 Until now, insurance has been making billion-dollar decisions using outdated tools.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. We’re backed by a16z, Highland Europe, and Battery Ventures, scaling globally and trusted by nearly 50 of the world’s largest insurers, with zero churn and billions in premiums flowing through hx. hx is evolving rapidly — expanding into new lines, geographies, and use cases, with AI and automation redefining what’s possible. Think of hx as a hybrid between in-house and consulting: you’ll combine actuarial depth with consulting mindset to guide transformations and shape how organisations adopt change. If that sounds like you, join us in building what comes next.

About Our Pricing & Innovation Team: You’ll apply your actuarial expertise across many insurers, seeing first-hand how the most advanced players transform pricing and shape best practice for the wider market. The Senior Pricing Actuary role sits at the center 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 to understand challenges, design solutions, and cast a vision for how pricing and underwriting can evolve. The team bridges actuarial depth with technical delivery and product insight, bringing credibility in pricing while exploring new methods, data, and technology to help clients adopt AI-enabled workflows and portfolio intelligence.

Responsibilities, qualifications, and the rest of the role are described below; hx is evolving rapidly and your work will help clients keep pace while informing our platform’s ongoing development.

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 — deploying new models, re-engineering workflows, and embedding 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 qualified actuary with several years of pricing experience in commercial, specialty, or reinsurance markets (reinsurance a strong plus).
• Built and deployed pricing models that improved underwriting outcomes, with hands-on technical capability (R, Python, data pipelines) and proven project delivery.
• Influenced senior stakeholders beyond the model — shaping workflows, governance, or portfolio strategy — through strong communication and presentation skills.
• Demonstrated commercial awareness in consulting, transformation, or client-facing roles, showing how actuarial expertise drives measurable business outcomes.
• Shown curiosity and a proactive mindset, exploring new methodologies, technologies, or data sources to advance pricing practice.

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.

Benefits

• £5,000 training and conference budget for individual and group development.
• 25 days of holiday plus 8 bank holidays (33 days total).
• Company pension scheme via Penfold.
• Mental health support and therapy via Spectrum.life.
• Individual well-being allowance via Juno.
• Private healthcare insurance through AXA.
• Income protection and Life Insurance.
• Cycle to Work Scheme

Additional Perks

• Top-spec equipment (laptop, screens, adjustable desks, etc.).
• Regular hackathons, lunch & learns, and socials, both remote and in-person, to foster collaboration and creativity.
• Team breakfasts and lunches, fully stocked snacks and drinks, and a fun, creative office at The Ministry.
• Access to cutting-edge AI tools and experimentation budget, giving you the freedom to test, learn, and innovate ahead of the market.
