The Promotion Packet for AI Engineers Who Didn't Ship a Feature
The AI engineer with the strongest case for promotion on your team has a promotion packet that looks empty. Two quarters of work and the impact graph is a flat line. The eval-regression rate that used to spike to 12% on every model swap now sits at 4%. The $40k/month cost spike that finance was about to escalate never reached finance because somebody added a budget guard to the gateway. The P0 incident that would have made the company's status page never happened because a kill-switch tripped and routed traffic to the previous prompt version.
The packet has nothing to write in the "shipped X" column. The calibration committee sits down with two engineers side by side: one who shipped two visible features this half, one who quietly absorbed the load that made those features possible. The committee, doing what it has always done, rates the shipper higher. The infra-shaped engineer either takes a "meets expectations" rating they don't deserve and quits inside a quarter, or learns to write the packet in a language the committee can actually read.
