Role
Who you are
- 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
- Served as an early or founding data hire, translating messy questions from senior leaders into clear designs, spotting systemic issues and raising the quality bar beyond your core remit
What the job involves
- 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
- 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
- Establishing data contracts, data quality checks, audit and observability patterns so teams can trust, debug and self-serve confidently across the platform
- Acting as a founding partner to product, FP&A, people and GTM by unblocking ambiguous data problems, setting data standards from scratch and driving the company’s AI readiness

Our take
hyperexponential was created to provide modelling software to help people and businesses build, deploy and manage analytical models that work with small, sparse and fragmented datasets. Its goal is to make teams more agile, collaborate more deeply, and work more productively.
hyperexponential's pricing and data-driven decision-making software is built for the speciality and commercial insurance markets. The product has broad applications, but the company's initial focus is on speciality insurance, a sector the founders know well, having worked there for more than a decade.
The company's making a name for itself too, working with some of Europe's biggest insurers to transform how pricing decisions are made. And its newest launch, hx AI, blends powerful AI with its core platform to help insurers build smarter models, faster. It's a strong signal that hyperexponential is not just growing, but ready to lead the way.
