Senior Engineer - AI

Engineering at hyperexponential

At hyperexponential (hx) we are transforming the traditional insurance industry with our groundbreaking SaaS platform, hx Renew. Insurers use it to build complex mathematical models that enable smarter, faster pricing decisions—whether it’s calculating the cost to insure a global superstar’s concert tour or protecting entire states from natural disasters.

With hx Renew, insurers can rapidly develop and iterate pricing models in Python and React within a modern software environment, free from the burden of legacy tech. What once took months now takes weeks—or even days. This agility has made our product the go-to platform for insurers worldwide.

We closed 2024 with remarkable milestones: doubling our revenue, raising $73M in Series B funding, setting course to offer Portfolio Solutions supported by AI. Our next ambitious target? Reaching $100M in revenue within the next 2-3 years and becoming an Insurtech Unicorn with a $1B valuation. Ambitious? Absolutely. Achievable? Without a doubt.
