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.

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 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
