At hyperexponential, were building the AI-powered platform that enables the worlds 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Until now, insurance has been making billion-dollar decisions using outdated tools. Were 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, were scaling globally - already trusted by nearly 50 of the worlds 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 worlds 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 isnt tied to title or tenure; its defined by the challenges you take on and the discipline you bring. Surrounded by peers who stretch you, youll 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.
The Models team at hx is at the heart of our mission to empower customers with the tools to write, version, test, and visualise their models, directly impacting the core functionality of our platform. We are responsible for rearchitecting our technology stack to deliver features rapidly and securely, ensuring our services can handle increasingly complex and nested customer data.
Our team blends deep technical skill with a culture of collaboration, ownership, and open communication. We work closely across disciplines, tackling complex data and performance challenges that drive real customer value. Constructive challenge and transparent leadership are central to how we operate, with a focus on delivering reliable, scalable solutions.
As a Senior Backend Engineer, you will play a pivotal role in improving the scalability and reliability of the Models service, accelerating delivery through well-designed abstractions and strong software architecture decisions. You will also be a cultural force, leading by example in ownership, kindness, and proactive problem-solving.
