Mobile Engineer

Concentrated in consumer companies. Releases are slow and hard to roll back.

Full archetype card in progress

This role is mapped and its data is live — the figures on the field page come from parsing real postings. The full card — a decoded posting, the interview loop, a worked transcript of the decisive round, a three-week plan and pay bands — is still being written.

The themes below are complete, and are the more useful half.

The book for this field

Software Engineering

What postings now ask for, system design at the level actually assessed, product sense for engineers, code and review, debugging and the coding round, what changes from mid to staff, the loop round by round, and choosing a track.

Skills every archetype tests

These are shared across every field on this site — the same question asked in different vocabulary — so preparation here compounds rather than being spent once. The book above is specific to your field.

Failure and incident narrativeEvery archetype asks for this story. The outage is the setting; the decisions are the content.READ THE CHAPTER →Latency and cost arithmeticThe one piece of maths that is genuinely counterintuitive — and it comes up in every agent interview.READ THE CHAPTER →Measuring what resists measurementTested in every field on this site under a different name — evals, SLOs, DORA, ablations. Named in 59% of AI and 42% of platform postings, and almost nobody studies it deliberately.READ THE CHAPTER →
