Job description

👶 About Junior

We’re building cutting-edge LLM-powered tools to supercharge the investment research process for private market investors. Our clients include several of the world’s top 10 private equity and consulting firms, and are responsible for investing billions of dollars annually. We’re a profitable, bootstrapped company with a growing team of 26 based in London and NYC.

We 10x’d our revenue in 2025.

💡 Role Description

We’re hiring our first engineer dedicated to the internal data and operations platform that powers how the company runs.

You’ll design and build the systems that support our commercial, product, and operations teams - helping automate workflows, improve decision-making, and enable the company to move significantly faster.

This is a high-ownership backend/data engineering role where you’ll work across data pipelines, integrations, automation, and internal infrastructure.

You’ll have the opportunity to:

• Design and build an AI-first internal platform from the ground up
• Own the architecture of our internal data systems and pipelines
• Build automation and integrations across our product, CRM, and financial systems
• Work on LLM-powered workflows, agents, and automation
• Ship tools quickly and see them used immediately across the company
• Help shape engineering culture and internal infrastructure decisions

🔧 Example Projects You’ll Work On:

Customer Health Intelligence System

• Design data pipelines that consolidate product usage, CRM data, and user feedback into a unified system of record.
• Build automated signals and alerts that detect churn risk, usage drops, or emerging product issues - enabling the team to act quickly.

User Feedback → Product Development Pipeline

• Build internal tooling that processes feedback calls with users.
• Use LLMs to extract themes, cluster feature requests, and surface the most important insights to the product team.

Billing & Revenue Infrastructure

• Design systems to support complex B2B pricing models — combining usage-based, seat-based, and platform fees.
• Automate invoicing, reconciliation, and financial reporting.

Internal Data Platform

• Build and own our internal data platform, integrating product telemetry, CRM data, and financial systems.
• Create reliable pipelines and APIs that power reporting, automation, and decision-making across the company.

🔥 About You

We’re looking for a Backend/Data Engineer who enjoys building systems that make a company run better.

You might be a good fit if you:

• Are based in London and excited to work from our Farringdon office (5 days/week)
• Have experience owning technical projects end-to-end, from architecture through production
• Enjoy translating business problems into clean technical systems and automation
• Like building high-leverage internal platforms that make teams dramatically more efficient
• Have strong experience with PostgreSQL and modern data platforms (Snowflake, BigQuery, Databricks, Firebolt, etc.)
• Write production code in Python, Node.js, or TypeScript
• Thrive in fast-moving startup environments and enjoy shipping quickly while maintaining strong engineering standards

Bonus

Experience building AI-enabled workflows, automation systems, or internal developer platforms.
