Nobody notices a pipeline that works. Your resume has to make the invisible visible: scale, reliability, and cost.
Three things, in order of weight.
Data volume and job scale you were responsible for
Reliability: SLA, on-time rate, how you handled late or dirty data
Cost and performance work on storage and compute
Work them into your title, project descriptions and skills — don't pile them into a list.
Each cover is the template itself, rendered.
Long, structured bullets sit well in one column.
Clear section separation for platform vs. project work.
Clean and ATS-safe.
One page. Unless you have 10+ years and a genuinely full second page, the second page only dilutes the first. Put data volume and job scale you were responsible for above the fold.
Listing the stack (Spark, Flink, Hive) with no scale behind it. It is the single most common reason this role gets screened out, and fixing it matters far more than changing templates.
Use AI for the first draft, then verify every claim and number yourself and reorder keywords against the target job description. AI handles speed; the content is still your responsibility.
