Full Job Description
We're looking for a Software Engineer with deep expertise in backend to help develop the next-generation AI platform for market due diligence. You'll architect the AI-powered engine that orchestrates autonomous research agents and voice AI pipelines to create the next-generation of market reports for investment professionals in Private Equity, Hedge Funds, Private Credit, and Corporate M&A.

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 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 (AI agent orchestration, voice AI pipelines, app and API performance, intelligent automations)
  • Architect scalable backend services with complex async processing and background task orchestration
  • 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 Python backend experience
  • Strong expertise building production APIs (FastAPI, Django, or similar)
  • 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
  • Understanding of async programming, job queues, and distributed systems
  • Experience with background task orchestration and async processing workflows


Bonus:
  • Experience with Anthropic Claude API and Agent SDK
  • Familiarity with agent orchestration frameworks
  • Background in AI/ML systems or voice AI
  • Familiarity with vector databases and semantic search (pg_vector, etc.)
  • Experience with Supabase or similar Backend-as-a-Service platforms
  • Previous startup experience


Who you are:
  • Obsess over system design and think deeply about technical trade-offs
  • 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
