Meet the

Model Development

team

We build the pricing brains that power hx Renew.

Model Development at hx sits at the intersection of production engineering, actuarial complexity and customer delivery: where you turn legacy pricing logic into modern, trusted models.

Explore our Teams

Model Development

Is a collaborative, highly technical team that works directly with customers to build production-grade pricing and reinsurance models in hx Renew. You translate legacy Excel models or design new ones from scratch, support customers to own and extend their models, and work across global carriers, reinsurers and specialist MGAs. This is high-stakes, customer-facing work where you're often the main technical touchpoint customers have with hx. You need strong coding craft, clear communication under pressure, and the ability to move between technical depth and stakeholder conversations seamlessly.

How MDT is structured

One team - focused on rapid, agile delivery

One team - focused on rapid, agile delivery

Building and translating models

Wide range of pricing models across markets and lines. Some customers want speed. Others want transformation. AI-assisted tools speed up development, but the thinking and relationship-building are still yours.

Coaching and enabling customers

You don't just deliver models and walk away. You support customer teams to extend and maintain their own models, ensuring they can move confidently and independently once you've laid the foundation.

Sharing patterns across the team

Regular show and tell sessions mean you solve hard problems once, then share the solution. Clever model patterns become reusable components that accelerate future builds across all customers.

Working at the intersection of customer delivery and product

Model Developers translate complex pricing models - often built in Excel over years - into production-grade code that runs on the hx platform. You work directly with customer actuaries to understand their pricing logic, business rules and edge cases, then rebuild it in a way that's maintainable, collaborative and performs at scale.

Building models that underwriters trust

You don't just make code work - you make it match how actuaries and underwriters think. This means maintaining transparency in rating logic, building clear audit trails, and ensuring models produce explainable results that underwriters can defend to regulators and reinsurers. The challenge is balancing technical efficiency with the need for actuarial credibility.

Customer-specific implementations

Every customer's pricing approach is different - different perils, rating factors, regulatory requirements. You build tailored models for each insurer's book of business, working through their historical data, understanding their appetite and risk tolerances, and implementing logic that matches how they actually underwrite.

Converting actuarial logic into production code

Model Developers sit between customer-specific implementation and platform capabilities. You identify patterns across customer models that should become platform features, share product requirements back based on real implementation challenges, and help shape how the hx platform evolves to support increasingly complex pricing needs.

MDT’s playful use cases for hx Renew

Every technical new joiner builds and deploys a project inside hx renew, a way to learn fast, go deep, and show what’s possible from day one.

I’ve always wanted to create a temperature quilt, but realised it would involve a lot of calculations to estimate fabric needs. To simplify the process, I built a model using daily temperature data. I plan to extend it with three years of historical data to predict next year’s fabric requirements and compare the results to the actual data. Through this project, I learned about CUICs and loved seeing the visuals come to life.

The right environment

changes everything.

To thrive in

Model Development

at hx, you will need

The patterns of our very best MDT people

They're comfortable in front of customers

Translating complex pricing models - often built in Excel over years - into production-grade code. You work directly with actuaries to understand their pricing logic, business rules and edge cases, then rebuild it in a way that's maintainable, collaborative and performs at scale.

They write production-grade code, not prototypes

Your code goes live with real underwriters. It's not a university project or a one-off script. You develop from capable coder to building fully tested, maintainable models that hold up under scrutiny and support real business decisions.

They own outcomes, not just tasks

You don't just write code and move on. You see projects through, support customers to extend their models, and take responsibility for whether the engagement succeeds or needs adjustment along the way.

What the environment gives back

Scaffolding that scales with readiness

You start with strong support and senior partnership. As you grow, you lead engagements end to end and present at user groups. We guide you to the edge of your comfort zone while owning the risk at leadership level.

You develop two skill sets most people build separately

Production-grade engineering and stakeholder collaboration under pressure. You learn how to write robust code and how to build trust with C-suite executives. Most people spend years building one or the other - you develop both simultaneously.

Compressed learning across markets

You move between global carriers, specialist MGAs and complex reinsurance structures. You see how different markets price risk, how different customers work, and you build relationships and models that matter.
