Job Term


Company Website

We're disrupting the insurance industry with our platform Renew, which insurers use to build mathematical models to make complex pricing decisions. Solving questions such as:

  • What are the chances that SpaceX's next launch will fail?
  • What are the chances of Kanye West cancelling his sell-out tour?

Renew is self-serve - allowing insurance professionals to login to our development platform and build their own models in a "pro-code" environment, using the open source language of Python.

The hx Model Development Team is not a typical consultancy; the technical/actuarial work we do here is quite different from most places. We don’t take on traditional “transformations” ourselves (we have brilliant partners for that) – we specialise in handling the most difficult or interesting problems for our clients, where only a combination of the very best market expertise and Renew knowledge will do. Here are some example challenges we will take on this year:

  • How do we make sure our clients are first-to-market with rapidly built, world class pricing models in Renew?
  • How do we integrate machine learning into Renew to allow our customers to better understand risks via data triage or optimise their portfolios on the fly?
  • How do we build out innovative assets to be used as parts of demos and PoCs, showcasing the full capabilities of the platform?

This role will work along side the rest of the hx Model Development Team (MDT), and closely partner across the organisation including with:

  • Sales - giving bespoke demos to prospective clients and building out innovative Proof of Concepts (PoCs) as part of the Sales process
  • Learning & Education - supporting the learning team to build out new learning pathways for users of our platform, Renew, particularly as it develops in line with our innovations
  • Product - ideating new features and innovative solutions, and working closely with the Product-Engineering team to then bring them to (product) life!

Key Responsibilities

Note: hx is still a relatively early-stage business, and our culture prizes initiative highly - as such this section is a good indicator of your role, but the list isn’t exhaustive.

Expand the capabilities of Renew across the Underwriting and Pricing process

  • The emphasis in this workstream will be to build scalable, repeatable innovations which our wider customer base can then benefit from. Examples of this may include building an automated follow-syndicate in partnership with one of our new customers, or building the ML tooling required to achieve data-driven triaging of risks
  • Develop assets to support the Sales process, specifically for PoCs and Demos, and lead the workshops with potential clients, demonstrating the power of the platform in live sessions (both virtually and face to face)
  • Consult with our customers to maximise the business value they are getting from Renew by, for example, conducting Business Value Workshops with Underwriters or reviewing and optimising their pricing tool landscape

Work directly with customer actuarial teams, underwriters and other customer teams in solving their hardest actuarial problems

  • Using your experience in the pricing market, work closely with the rest of the Model Development Team to support our customers in building best practice pricing models that are seamlessly integrated and employing cutting edge approaches
  • Drive initiatives that increase the usage of Renew with our customers, both with core functionality and pushing the boundaries of the platform to pave the way for innovation in pricing and underwriting

Enable the users of our platform to continually iterate and generate business value as it develops out with our innovations

  • Implement and improve our model development standards and platform capabilities, collaborating with the Head of Learning to build out world-class digital learning pathways

You will join hx at the most exciting stage of a rapid growth - we are scaling up across multiple business functions including Learning, Marketing, Sales and Customer Success - you will get to see this and contribute to that growth in many different ways. You can get stuck in many exciting initiatives such as hx University (where our engineers and model developers get introduced to the newest and most exciting tech tools and languages!) as well as the fun stuff like Social Committee or OKRs Champions!

Initial deliverables

You will:

  • Within the first month
    • Completed hx’s sales enablement training, and be demoing our platform to potential new customers
    • Be trained on the Renew platform and shipped your first models in Python

    • Be consistently contributing to and improving our internal and external training & development materials
  • Within 3 months
    • You will be working with our customers, whether building models as part of a PoC, client onboarding, a live project or consulting work
    • Be certified to train new hx team members and customers to build their own models within Renew
    • When not working on customer or sales opportunities, you will be responsible for independently driving initiatives which increases the value all our customers get from modelling in Renew - this may include building a model suite all customers can use on day one, delivering automated insurance pricing, working out how machine learning can accelerate our customers decision making, or researching and deploying an MI suite which automatically reports against regulatory standards


If you're the right fit for this role, you will be able to show clear evidence that you are:
