We work across Product, CS, Sales and Solutions Architecture daily.
How MDT is structured
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 ours.
Coaching and enabling customers
We deliver models and stay involved. We support customer teams to extend and maintain their own models, ensuring they can move confidently and independently once we've laid the foundation.
Sharing patterns across the team
Regular show and tell sessions mean we solve hard problems once, then share the solution. Clever model patterns become reusable components that accelerate future builds across all customers.

The patterns of our very best MDT people
They're comfortable in front of customers
Most of their time is on customer projects. They're often the main technical face customers see. They explain complex logic clearly and build trust with actuaries, IT teams and C-suite stakeholders under real pressure. They work directly with actuaries to understand pricing logic, business rules and edge cases, then rebuild it in a way that's maintainable, collaborative and performs at scale.
They develop production-grade code with care
Their code goes live with real underwriters supporting real business decisions. They develop from capable coder to building fully tested, maintainable models that hold up under scrutiny. This means attention to detail, clear documentation, and code that others can understand and extend.
They own outcomes, not just tasks
They stay involved beyond the initial build. They see projects through, support customers to extend their models, and take responsibility for whether the engagement succeeds or needs adjustment along the way. This means ongoing collaboration, not just handoff.
What the environment gives back
Scaffolding that grows with you
We start with strong support and senior partnership. As we grow, we lead engagements end to end and present at user groups. The team guides us to the edge of our comfort zone while owning the risk at leadership level.
Developing two skill sets together
Production-grade engineering and stakeholder collaboration under pressure. We learn how to write robust code and how to build trust with C-suite executives. Most people spend years building one or the other - we develop both simultaneously.
Learning across markets and relationships
We move between global carriers, specialist MGAs and complex reinsurance structures. We see how different markets price risk, how different customers work, and we build relationships and models that matter.
