Description: Join a high-growth startup as a foundational engineer building an AI-native platform for M&A and private equity.

This role offers direct influence over the company's technical future.

• Strong commercial backing from the Big Change ecosystem and Cambridge AI researchers, moving rapidly toward product-market fit with active early customers.

What you will do

• Design, build, and operate a production Saa S platform using Python (Fast API), React, and Postgre SQL, ensuring high performance and security.
• Architect and scale cloud infrastructure on AWS using Terraform, ECS, and Lambda while maintaining multi-tenant security and ISO 27001 standards.
• Develop and optimize hybrid search capabilities and data pipelines, integrating LLMs to automate complex research tasks for dealmakers.

The ideal candidate

• 7+ years of experience building and shipping production-grade systems in startup or small-company environments with a strong bias for action.
• Expert proficiency across the full stack, specifically Python, React/Type Script, Postgre SQL, and hands-on AWS infrastructure management.
• Proven ability to make sound architectural decisions independently and a genuine enthusiasm for leveraging AI to solve fragmented manual workflows.
