The Three-Person Software Team: A 2025–2030 Preview

By Cortexa · 21 Aug 2025

TL;DR: AI compresses software teams. The durable trio is Delivery Manager, Prompt Engineer, and Senior Architect. Everything else becomes a service, a tool, or an occasional role.

Why this happens

Codegen, tests, refactors, and glue work move to AI. What remains human: direction, judgment, and governance.

The roles

Getting started

  1. Pick one workflow (e.g., support knowledge assistant).
  2. Stand up private RAG with logging + redaction.
  3. Define a 25-case golden set + latency/error SLOs.
