The stack
Four capabilities, not one
Almost every engineer has part of this. The rarity — and the pay — comes from holding all four at once.
- 1. Technical depth — build production systems fast in unfamiliar terrain
- 2. Business acumen — understand what the organisation actually needs
- 3. Communication under pressure — hold the room when it gets tense
- 4. High agency under ambiguity — decide and move without a full spec
