About the role

We're looking for a Software Engineer with deep expertise in full-stack development to help develop the next-generation AI platform for market due diligence. You'll own complete features end-to-end - from AI-powered backend systems to polished frontend interfaces that investment professionals in Private Equity, Hedge Funds, Private Credit, and Corporate M&A use to make billion-dollar decisions.

About DiligenceSquared

DiligenceSquared is the AI-native consulting firm. We deliver investment-grade market research and commercial due diligence, powered by AI agents and led by experienced consultants. Our founding team brings deep experience from Blackstone and BCG, and we're backed by Y Combinator and Relentless. Our clients include 5 of the 10 largest private equity firms in the world and represent more than $3T in combined AUM.

What you will do

  • Build new product features and experiences end-to-end, everything from database models to API endpoints, and integrating them with UI components for our Web App and AI Voice Agent application
  • Design and build new AI-powered modules from scratch (e.g., market sizing, competitive analysis) that become core capabilities of our research platform
  • Build and own product foundations across the stack (AI agent orchestration, voice AI pipelines, interactive data visualization, app and API performance, intelligent automations)
  • 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 full-stack development experience
  • Strong proficiency in React/TypeScript and Python
  • Experience building agentic systems with LLM platforms (Anthropic, OpenAI, or similar)
  • Deep hands-on experience with LLMs in production - building reliable agentic systems, not just API calls
  • Experience with PostgreSQL and SQL database design
  • Experience with modern frontend architecture, state management, and API design
  • Track record of shipping user-facing products end-to-end

Bonus

  • Experience with Next.js and FastAPI
  • Experience with Anthropic Claude API and Agent SDK
  • Familiarity with agent orchestration frameworks
  • Background building interfaces for AI/ML products or data-intensive applications
  • Familiarity with vector databases and semantic search
  • Experience with Supabase
  • Previous startup experience

Who you are

  • Love owning complete features rather than just frontend or backend pieces
  • Can context-switch effectively between system design and UI polish
  • 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
