Data Architect

💡 Role Overview

We’re hiring our first engineer dedicated to internal go-to-market and operations systems. This is a foundational role where you’ll design and build an AI-first internal stack from scratch, enabling Sales, Finance, Ops, and Customer Success to operate at maximum velocity.

You’ll have end-to-end ownership across tooling, data, and automation; shaping not just systems, but how the company runs.

In this role, you will:

  • Architect and implement an AI-native internal tech stack, influencing infrastructure decisions and long-term direction
  • Rapidly ship internal tools and workflows, iterating directly with teammates who use them daily
  • Build and maintain our data warehouse and internal data architecture
  • Develop automation systems leveraging LLMs, agents, and modern AI tooling
  • Help define engineering standards and culture as we scale

🔥 About You

We’re looking for someone who genuinely enjoys building tools that make commercial teams faster and more effective.

You likely:

  • Have led projects independently from idea to production, and are comfortable collaborating with multiple senior stakeholders
  • Communicate clearly and can translate ambiguous business needs into structured technical solutions
  • Are familiar with commercial and operational tooling such as Notion, Slack, Retool, Amplitude, Stripe (or similar ecosystems)
  • Sales, Finance, Ops, and Customer Success teams will rely on you to improve efficiency and introduce AI-driven workflows
  • Are highly proficient in PostgreSQL and at least one major data platform (e.g., Snowflake, BigQuery, Databricks, Firebolt)
  • Experience with Node.js and TypeScript is a plus
  • Thrive in fast-paced startup environments and feel energized by ambiguity
  • Move quickly and constantly look for ways to ship faster

Bonus: Experience designing or building AI-powered internal tools or automation systems.

🚀 Why Join Us

  • Autonomy with mentorship: You’ll be the first London-based engineer with high ownership, while receiving guidance from a senior engineering team in NYC. You’ll travel to NYC for onboarding and project collaboration.
  • Exceptional traction: 10× revenue growth in 2025, profitable, and trusted by leading firms including MBB, Big 4, and top-tier mega-funds.
  • Flat structure: Minimal layers between you and leadership. Direct access to the CTO and CEO, with meaningful responsibility from day one.
