Highlights

Passages saved from the original.

    • Senior engineers now do “system orchestration,” not just coding: architecting, directing AI agents, and keeping the whole system coherent.
    • Scope, not skill, is the real differentiator: deciding what to build, not just executing it well.
    • AI agents shifted the hard part from “how do I build this” to “should we build this,” compressing timelines from weeks to days.
  • There is no longer a clean line separating individual contributor (IC) and technical lead roles
  • The title says “engineer,” but the scope of the work has shifted toward something much broader: system orchestration.
  • Writing code is becoming something you direct rather than something you do by hand.
  • the complexity has not disappeared. It has moved from implementation to decision making.
  • system orchestration. As codebases grow and toolchains become more complex (AI agents, platform engineering, microservices), someone must understand how all the components interact
  • Complexity has not gone away. It has moved from syntax and implementation to architecture and decision making

Summary AI-generated

Summarised by an AI assistant when this source was saved. Double-check against the original.

In summary, senior engineers have evolved into system orchestrators who prioritize strategic scope and influence over mere code execution.

  • Focus on system orchestration and architectural direction rather than just writing code.
  • Prioritize technical judgment by defining what to build, not just how.
  • Enhance communication and influence to align teams and articulate feasibility without authority.
  • Collaborate symbiotically with managers to shape the entire engineering ecosystem.
