Founding Engineer - Frontend

We’re looking for a Founding Software Engineer with deep expertise in frontend to help develop the next-generation AI platform for market due diligence. You'll own the frontend for AI-powered research workflows - building interfaces for voice AI interactions and interactive data visualization to create the next-generation of market reports for investment professionals in Private Equity, Hedge Funds, Private Credit, and Corporate M&A.

About DiligenceSquared

DiligenceSquared automates commercial due diligence for Private Equity funds. We're YC-backed, just raised a significant Seed round, and our clients include some of the world's largest PE funds.

The market is $10B+ annually - PE funds pay McKinsey, BCG, and Bain $500K-$1M per report. Our AI agents do this work faster, cheaper, and with full auditability (every claim linked to source).

Our founders bought and sold these reports at Blackstone and BCG where they held senior positions. We have deep experience with the workflows and know exactly what the market needs - and now we're automating it.

What you’ll do

• Own the entire frontend experience for our AI-powered platform, creating interfaces that delight users at top investment firms
• Transform complex data and AI outputs into intuitive, actionable interfaces
• Build performant, scalable frontend architecture that can handle intensive real-time operations
• Push the boundaries of what's possible with modern web technologies
• Apply learnings from each project into the product, so we're 1% better everyday (Law of Compounding is real. After all, we are founded by investment professionals)

Qualifications:

• 3+ years of professional React/TypeScript experience
• Deep expertise in modern frontend architecture and state management
• Experience building complex, data-heavy applications
• Experience with Next.js or similar React frameworks
• Portfolio demonstrating craft and attention to detail
• Passion for UI/UX and making complex information accessible

Bonus:

• Background building interfaces for AI/ML products
• Experience with real-time communication features
• Familiarity with voice AI integrations
• Previous startup experience

Who you are

• Obsess over craft - every interaction and layout decision matters
• Take pride in your code and want to work with others who do the same
• Act with Urgency so we can empower you with Agency
• Pay high attention to detail and are curious about how great products work
• Feel discomfort when things don't move as fast as you feel they should
