We are transforming the insurance industry through the power of decision intelligence. Disconnected systems, unruly data, and outdated processes are undermining the ability of insurers to make their best decisions. We see a better way. We combine first-hand actuarial experience and first-class engineering expertise with a passion for technology, to develop solutions that enable quicker, smarter decision making. Teams are more agile, collaborate more deeply, and work more productively. They update their models more regularly, and have access to a broader array of tools than ever before. Our progressive approach, effective integration and continued support ensure our software delivers from day one and continues to evolve to meet the needs of your future ambitions. We work closely with our clients so they can embrace the digital revolution, enhance productivity and transform the performance of their organisation.

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.
In just five years, our winning formula has earned the trust of industry giants like Aviva and Top 5 US insurers, as well as cutting-edge innovators like Convex and Inigo. Our engineering team—made up of some of the brightest (and kindest!) minds in the industry—pushes technological boundaries every day through creative innovation and regular hackathons.
Your Mission The Policies Team works at the heart of our product hx Renew, building a system that keeps track of all our customers’ models, policies and much more! Sounds like a boring CRUD? We have domain logic and invariants to show for and to keep track of. Your mission – should you choose to accept it – will be to join us on the journey of chopping the monolith, introducing DDD and hexagonal architecture to our code, all while delivering brand new workflows and features.
Key Responsibilities
Any Experience on the following would be great!
The majority of our work lies with Kotlin, Spring & Hibernate, so experience with Kotlin would be best, but any JVM language will be highly relevant as well.
You will be upskilled in Kotlin if you didn’t already use it!
We will focus on deeper architectural work like modularising our monolith and isolating technical solutions like authentication and authorisation.
Additionally, we are conducting product work on new features expanding our product coverage.
