Hi, I'm Tom Clark - CIO, CISO, and hx employee #9.
I'm the executive in charge of our Systems & Security function. I joined in 2020 at seed stage, and I've been here through Series A, Series B, and everything in between - watching us grow from nine people to more than 250. I’m six years in, and I've never been more excited about what's ahead.
Fun fact: I didn't come from insurance. I came from TV and media - if you've ever used BBC iPlayer, ITVX, or listened to Capital Radio, I helped make them. I ended up in insurance and became, perhaps unexpectedly, one of the industry's biggest cheerleaders.
I know what you're thinking: insurance isn't cool. I can change your mind in five minutes, or your money back. And the best bit? What we're building with hxOS is cooler still. We take a product-centric, customer-centric view to internal IT - the same rigour and craft you'd bring to any customer-facing product. That's what makes this role different, and it's what I'm most excited about.
Let’s speak soon.

About hyperexponential (hx)
At hyperexponential, we're building the AI-powered platform that enables the world's most critical decisions in a $7 trillion industry: which risks to take, and how to price them. These are decisions that shape real-world outcomes - whether rockets successfully launch into space, autonomous vehicles make it to market, or communities recover after major storms.
Until now, insurance has been making billion-dollar decisions using outdated tools. We're changing that. Our platform brings together data, AI, and human expertise to give insurers the fastest path from submission to decision. We help them move faster, act smarter, and take on more risk with confidence.
Backed by a16z, Highland Europe, and Battery Ventures, we're scaling globally. We are already trusted by nearly 60 of the world's largest insurers, with zero churn and billions in premiums flowing through hx.
What began as a single product in one market has rapidly evolved into a multi-product, multi-territory platform powering every stage of pricing and underwriting. AI is at the core of what we do: from building the world's first domain-specific AI peer programmer for insurance (think GitHub Copilot with a PhD in actuarial science) to shaping agentic workflows that reinvent how this industry operates.
About the SYSSEC team
hxOS is hx's internal operating system. It's the platform every person in the company uses and builds on: devices, meeting rooms, core applications, SSO, AI tools, data infrastructure, security and compliance. The Systems & Security (SYSSEC) team builds it, runs it, and keeps improving it. It'll never be finished. That's the point.
hxOS is as much a vision as a current reality. The foundations are solid, day to day runs well because it has to, nothing gets built on shaky ground. The more ambitious layers - federated, AI-native, product-led infrastructure that the whole business builds on - are what the team is building now.
About the role
The Systems Associate is one of the most visible faces of SYSSEC. They're the first point of contact for everything coming into the team, and the work ranges widely: a day might move from troubleshooting a device, to helping a team get more out of a new AI integration, to contributing to a piece of infrastructure the whole company will rely on. What ties it together is ownership: of the service experience, of the queue, and progressively of the platform itself.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The career story here is real. This person becomes hxOS's internal expert, the colleague people turn to when they want to understand what's possible, get more out of their tools, or navigate something new. That's a rare combination of technical depth, operational credibility, and genuine impact at the centre of how the company works.
This is an Associate/IC1 role, suited to a talented graduate or someone with a year or two behind them.
What you'll be doing
- Own the front door. Triage, prioritise, route, and keep stakeholders informed on everything coming into SYSSEC, applying an ITIL/ITSM lens to how work arrives, gets handled, and gets resolved. How it feels to reach out to SYSSEC starts and ends with how this person shows up.
- Improve the service, continuously. Good enough today is a problem tomorrow. Look for recurring patterns, find root causes, and change the conditions that created them, through better templates, self-serve paths, proactive communication, and process work that makes repeat tickets rarer over time.
- Build things that reduce the work. Scripts, automations, integrations, paved-road workflows. Engineer toil out of the system rather than just processing it, and contribute to the broader hxOS integration layer: connectors, routing logic, self-serve tooling that makes the platform more capable over time.
- Be a partner to the business. As the internal expert in hxOS, help colleagues get more out of their devices, applications, and AI tools. This isn't ticket resolution, it's helping people understand what's possible and removing friction between them and a platform designed to make them better at their jobs.
- Contribute to strategic delivery. Around 20% of the role is higher-leverage work: contributing to platform design, supporting infrastructure decisions, and building the technical foundations needed to take on bigger challenges over time.
What good looks like
- Reliable under volume. Owns a queue without being chased, keeps work moving and stakeholders informed, and holds the same standard whether it's a routine request or a change that touches critical infrastructure.
- Builds rather than just processes. Comfortable writing scripts and configuring automations, thinks in repeatable patterns rather than one-off fixes, and treats "make the next version of this job smaller" as the actual goal.
- Already AI-native, not AI-curious. Uses AI tools as a natural part of everyday work: triage, documentation, automation scaffolding, first-pass review. Has judgement about where it helps and where it doesn't, rather than reaching for it by default.
- Figures things out unprompted. Given a problem, researches it, tests it, forms a view, and comes back with a recommendation rather than a question. Comfortable with ambiguity, applies feedback fast, and is honest about what they do and don't know yet.
