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 the 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Until now, insurance has been making billion-dollar decisions using outdated tools.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 - helping them move faster, act smarter, and take on more risk with confidence.

Backed by a16z, Highland Europe, and Battery Ventures, we’re scaling globally - already trusted by nearly 50 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.

What makes hx different is the people who build it. Here, impact isn’t tied to title or tenure; it’s defined by the challenges you take on and the discipline you bring. Surrounded by peers who stretch you, you’ll do the best, hardest work of your life in a company engineered to endure.

If that sounds like you, join us in building what comes next.

About The Central Data Team Data sits at the heart of hx’s mission to reinvent how insurers understand, price, and take risk. As we expand globally and deepen our AI capabilities, the need for trustworthy, unified, and AI-ready data becomes a core strategic advantage.

The Central Data team is being built to provide that foundation: a single lakehouse, a shared semantic layer, and a set of retrieval and embedding capabilities that power everything from exec dashboards to agentic workflows. This team partners closely with product, FP&A, people, customer success, and GTM to define and deliver the company’s central source of truth.

As the Founding Central Data Engineer , you will shape this team’s standards, architecture, and culture. You will design and own the full stack of hx’s data platform and build the systems that underpin analytics today and AI systems tomorrow.

What You’ll Be Doing

• Designing, building and owning hx’s Databricks lakehouse, including workspaces, clusters, Unity Catalog, medallion architecture, Delta tables, RBAC and cost controls, becoming the central source of truth for the company.
• Implementing robust ELT pipelines (Spark, dbt or similar) with tests, documentation, CI and monitoring to deliver daily freshness and agreed hourly SLAs with ≤4h recovery for critical data.
• Modelling cross-domain Gold entities and certified metrics across customers, usage, pricing, finance, people and GTM with clear grain, history and reconciliation paths that power all exec and board reporting.
• Building hx’s first embedding, vector and retrieval layer over curated tables and documents, enabling live RAG and agent workflows such as premium explanations, version tracing and automated KPI summaries.

What you’ll need to have done

• Built and run a Databricks-style platform with medallion layers, Unity Catalog, RBAC, SLAs, cost tuning and runbooks that served as a company’s primary data environment.
• Delivered multi-domain models linking product/platform, finance, people and GTM data into coherent entities and certified metrics, including revenue reconciliation and historical tracking.
• Created production-grade data pipelines using SQL, Python, Spark and Git workflows with tests, alerts, logging and documentation that elevated engineering quality across a team.
• Built at least one real-world RAG or vector search system using embeddings, thoughtful chunking, metadata, evaluation and safe retrieval patterns.
• Used data as software: robust CI, clear acceptance criteria, debugging discipline, observability, dev-to-prod promotion and well-maintained runbooks.

You’re unlikely to thrive here if

• You prefer operating only within a predefined roadmap rather than shaping unclear, cross-functional problems into structured solutions.
• You avoid deep technical ownership of systems in favour of handing off responsibility to others.
• You’re uncomfortable working at pace, with high autonomy and evolving requirements as we build foundational data infrastructure.
• If reading our Culture Document leaves you feeling neutral rather than energised, hx may not be the place where you’ll do your best work. We’re building something that asks for commitment and conviction, and we want you to feel excited by the opportunity to grow with us.
