Model Developer

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 Until now, insurance has been making billion-dollar decisions using outdated tools.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 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.
