Pricing Actuary in City of London

Join to apply for the 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 Until now, insurance has been making billion-dollar decisions using outdated tools.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.

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.

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.

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.

Interview Process:

• Talent Partner Screen - 30 minutes.
• Hiring Manager Interview - 1 hour.
• Skills Assessment - 1 hour.
• Meet the Team - 2 x 30 minute chats.
• Values Interview - 60 minutes.
