Location: New York City - Full time onsite

Eligibility: US Residents Only

Requirement: Startup or high-bar tech environment experience (non-negotiable)

You'll own the data infrastructure that powers an AI platform trusted by household-name clients across sport, finance, and consumer - built by an exceptionally high-talent-bar team with serious backing and serious ambition.

This isn't a slides-and-stakeholders role. It's hands-on, high-ownership data engineering at a company scaling fast with the runway to match.

ℹ️ Very Important Notes

  • This role is for builders - if you're more comfortable presenting than building, this isn't for you
  • 5 days onsite NYC
  • You'll own a large-scale, proprietary data asset - scale matters, fragility doesn't
  • Startup experience is a hard requirement, not a preference

Must-Haves

  • Proven delivery of fast, resilient data pipelines and orchestration systems
  • Proficiency with Airflow, dbt, and/or SQLMesh
  • Python backend skills applied to data engineering workflows
  • True IC mentality - design, build, ship, own
  • Startup or VC-backed environment experience (or equivalent high-bar company)
  • AWS infrastructure exposure

Bonus Experience

  • Experience enabling AI or agentic access layers - AI retrieval and query interfaces, structured data orchestration
  • Exposure to key business systems of record in sales and marketing
  • Background in ML feature pipelines or data science workflows
  • Degree from a top CS programme

Hands-On Experience With

  • Snowflake and modern data warehouse architecture
  • Pipeline orchestration - Airflow, dbt, SQLMesh
  • Large-scale data integration and transformation
  • AWS infrastructure
  • Analytics engineering and data modelling

What You'll Be Doing

Pipeline & Platform Ownership

  • Own analytics engineering and data modelling across a Snowflake-powered warehouse
  • Build and scale integrations with key business systems as the data footprint grows
  • Develop fast, resilient pipelines that underpin the core AI platform

AI Infrastructure

  • Enable AI retrieval and query interfaces that make intelligent, real-time decisioning possible
  • Build the data foundation that powers the platform's most advanced capabilities

Scale & Scope

  • Work across a large-scale, proprietary data asset - this is serious infrastructure
  • Expand your scope over time, with a clear path to leading the Data Engineering function as the organisation grows

What They're Looking For

  • A true IC - hands on keys, not directing from a distance
  • 4-8 years of experience building and scaling data infrastructure
  • Scrappy, pragmatic, and obsessed with reliability and performance
  • Someone who wants to grow with a company, not just execute a brief

If you've got the Snowflake chops, the startup scars, and the IC mentality to own data infrastructure at scale - get in touch for a fast response.
