Engineering managers care about uptime, latency, and user scale. State your exact production numbers in the opening paragraph to prove reliability.
Mentioning specific tools like kubernetes, terraform, and docker demonstrates that you understand modern deployment pipelines and CI/CD practices.
Instead of claiming you write good code, state your test coverage percentages and the exact number of repositories you managed.
Mention a product launch or company value briefly to show you did your research without sounding overly flattering.
