ABOUT HYPEREXPONENTIAL (HX) 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 Until now, insurers have been making billion-dollar decisions using outdated tools.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 THE MODEL DEVELOPMENT TEAM The hyperexponential Model Development team (MDT) is a unique blend of engineers, actuaries, mathematicians and data scientists. We don’t take on traditional “transformations” (we have brilliant partners for that) – we specialise in handling only the most difficult and interesting problems our customers face, where only a combination of technical depth, market expertise and hx Renew knowledge will do. The MDT are the experts' experts of hx Renew, knowing it top-to-bottom, inside-out – both breadth and depth. You’ll learn its limits and which can be pushed. You’ll uncover every trick in the book, the secret combinations, and the shortcuts. You’ll combine all of this with a growing knowledge of insurance technology to present 'the art of the possible' to our customers and help shape cutting-edge tech, while working alongside some of the brightest, most ambitious people in the tech and insurance industries. WHAT YOU’LL BE DOING * Learn the hx Renew modelling platform, you’ll ship your first models independently within days. * Build and maintain models in Python for seamless integration, applying modern approaches. * Work directly with customer actuarial teams, partner developers and internal colleagues to solve complex coding problems. * Contribute to the development of best-practice guidance for Python model building. * Review and test models as part of our day-to-day quality assurance process. * Support the creation and improvement of our internal and external training and development materials. * Always look for ways to refine and improve our model development standards and ways of working. WHAT YOU’LL NEED TO HAVE DONE * Developed strong Python skills, we’ll help you level up, but you’ll need production-grade experience to start with impact. * Applied predictive modelling or advanced analytics methods (exposure to insurance or reinsurance pricing techniques is a bonus, but not essential). * Shown a self-starter attitude, operating autonomously in a high-trust, high-accountability environment, and proactively driving your own development. * Demonstrated a passion for experimenting with new approaches and technologies, through work or personal projects. YOU’RE UNLIKELY TO THRIVE HERE IF * You prefer following detailed instructions rather than experimenting and finding your own approach. * You are uncomfortable working directly with non-technical stakeholders to understand their challenges. * You avoid tackling ambiguous or open-ended problems where the solution 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 feel excited by the opportunity to grow with us. COMPENSATION At hx, we’re committed to salary transparency. You’ll always have clarity on pay early in the process - our Talent Partner will share details with you during initial conversations - and we’re working towards publishing salary information for all roles globally. Because we’re building at the intersection of technology/SaaS and insurance, our roles don’t always map neatly onto traditional benchmarks. Our approach is to design compensation that’s competitive in the market, fair across teams, and aligned with the impact our people make. Equity: We offer equity across all roles at hx, making it a significant component of total compensation. Your talent partner will be able to share more details about this.

ABOUT THE DESIGN TEAM We’ve just wrapped up a stellar first year of Design at hyperexponential. We have built a lean team of six, spanning Product Design, Brand Design, and Design Engineering, with experience from organisations like Miro, InVision, V7, Lakera, and QuantumBlack. Over the past year, we’ve reimagined both the platform and the hx brand through our new design language, Xpression, giving hx a distinct edge in an increasingly competitive market. We’re a tight-knit, highly creative group who believe in showing rather than telling, staying curious, and pushing for deep craft excellence. We value systems thinkers, creative flare, generalists and specialists, and the kind of genuine collaboration and trusted relationships needed for radical candour. At hx, design leads from the front and not the sidelines. We are proud of our work so far and understand the responsibility to help our organisation see what comes next. As we grow, we’re intentional about bringing in designers with unique skill sets and perspectives - people who can elevate the team and expand what we’re capable of. WHAT YOU’LL BE DOING * Designing intuitive, accessible product experiences across the hx platform, translating complex problems into clear, usable solutions with a focus on evolving our model developer experience from 0 → 1. * Partnering with product managers, engineers, and researchers to support discovery, ideation, and delivery on well-scoped product initiatives. * Contributing components and patterns to our design language system, Xpression, helping ensure consistency and quality across the product. * Maintaining a high bar for design craft through thoughtful interaction design, visual clarity, and iterative improvement based on feedback and data. * Using AI tools within your own workflow to support research synthesis, exploration, and prototyping, helping the team move faster without sacrificing quality. * Supporting AI-native discovery and collaboration by bringing structured design thinking into cross-functional work. WHAT YOU WILL NEED TO HAVE DONE * Experience designing end-to-end product experiences that are grounded in user needs and deliver clear value. * Hands-on experience working within a design system, including contributing or refining components and patterns. * A strong foundation in design craft, with attention to usability, accessibility, and interaction quality. * Experience collaborating closely with Product and Engineering in a cross-functional product team. * Demonstrable use of AI-enabled tools in your design workflow, applied thoughtfully to enhance—not replace—human judgment. * Clear communication skills and comfort participating in critique, feedback, and collaborative problem-solving. IS THIS ROLE FOR YOU? Time for some candour. Stepping into a new role is a big decision and we want to be transparent about what it feels like to work in the Design team and the type of mindset that helps people thrive at hx. Does this align with your own approach? * AI maximalists - We’re all-in on AI. As a lean team, It’s central to our pace, our craft, and our workflow. Every day we’re experimenting, inventing, and building our technical acumen. If that excites you, you’ll fit right in. * Owning ambiguity - Everyone here shares the responsibility of navigating ambiguity. As Designers, we operate with a high degree of autonomy and are expected to lead others through shifting problem spaces with clarity and conviction. * Radical candour - We separate our identity from our ideas. It’s the only way to build the trust required for real conversations and for producing our best work. Feedback flows freely here because we’re optimising for the success of the collective, not the ego of the individual. If reading our Culture Document leaves you feeling neutral rather than energised, hx may not be where you’ll do your best work.
