Your real edge is translation
Answer "Why does the JD treat R&D spend differently from production inference COGS and how should a TPM frame whether a costly experiment is worth running?" Use one lesson detail to support it.
Step 1 of 3
Your real edge is translationthe value that's hard to hire for
Engineers reason in latency, utilization and model quality. Finance reasons in margin, budget and forecast. The reason this role exists is that few people speak both fluently. You make a financial argument legible to an ML researcher and a technical argument legible to a CFO.
“To Finance I'd frame it as: routing simple queries to the smaller model cuts cost per active user by X% with no measurable quality regression, which protects gross margin as DAU grows. To the ML team I'd frame the same change as: here's the latency and eval budget it has to stay inside. Same decision, two languages.”
Do not pitch yourself as pure cost-cutting. A TPM who only ever argues to spend less will lose credibility with a research org whose whole job is to spend on bets that compound. Frame yourself as protecting margin while making sure the right bets get funded - efficiency in service of ambition, not against it.
