Infrastructure Engineer Resume
Skills & ATS Keywords

Aim for 32 to 48 named platform practices, tools, and DevEx surfaces, distributed across 8 short rows (build systems and monorepo, internal developer platform, languages and tooling, source control and CI platforms, infrastructure as code, containers and Kubernetes, developer experience and metrics, security and supply chain). Below 26 the file reads thin for an engineer who is supposed to build the platform 200 other engineers use daily; past 52 it reads like a glossary dump from someone who has never owned a BUILD file. Each line on the row has to be backed by a build-time win, a Backstage plugin, a golden-path template, a DORA dashboard, or an internal SDK release note. If nothing in your work proves the entry, it is filler.

Park it right under the Profile Summary, before the Work Experience block. The screens (Greenhouse, Lever, Ashby, Workday) and the platform-hiring tech leads both move down the file in a single sweep, and a clearly labelled block sitting near the top of page one banks more of its keyword weight than the same content tucked toward the end. On an Infrastructure Engineer file, the 8 named rows (build systems, IDP, languages, source control, IaC, Kubernetes, DevEx metrics, supply chain) let the panel pick out the Bazel, Backstage, and DORA signal in one pass.

Open the posting on a second screen and highlight every platform noun the description names twice or more: Bazel, Backstage, monorepo, golden path, remote-execution, DORA, OPA, the language stack (Go and Python at the platform tier), and the source-control flavor (GitHub Enterprise, GitLab self-managed). Move those into a 14 to 20 entry working list, hold it next to your Skills rows and your platform bullets, and close any gap truthfully: if the description asks for Backstage Scaffolder ownership and you have only edited a TechDocs page, do not park it in row one. Once the draft is tidy, push it through an ATS Checker so you can see exactly which platform tokens the parser is picking up.

The four titles share Kubernetes, Terraform, and a working knowledge of CI, yet the spine of each page sits in a different place. An Infrastructure Engineer page leads with the internal developer platform you build: the Bazel monorepo, the Backstage IDP, the golden-path templates, the build-time reductions, the engineers you onboarded onto the platform, the DORA scoreboard you wired up. A DevOps page leads with pipeline velocity for product squads (deploy lead time, GitOps adoption, Terraform-module authoring for product teams to consume). A Cloud Engineer page leads with cloud-native foundations (landing zones, multi-account architecture, IAM at scale, FinOps). An SRE page leads with reliability ownership (SLOs, error budgets, chaos, on-call program design). Where a DevOps bullet says cut deploy lead time from 22 minutes to 9, an IE bullet says migrated 8M LOC monorepo from Webpack to Bazel with remote-execution, cut median CI time from 28 minutes to 9, adopted by 140 engineers. If the role you want is Infrastructure or Platform Engineer, lead each work block with a build-system, IDP, or developer-experience win.

Not exclusively, but the file has to show something equivalent. The internal-platform signal sits in any of these forms: ownership of a build system at scale (Bazel, Pants, Nx, Turborepo, Buck), a self-service developer portal you stood up (Backstage, Cortex, Roadie, Port, OpsLevel), a golden-path template program adopted by a measurable engineer count, or an internal SDK or platform CLI you authored that other product teams import. If your last three roles were product-team CI tickets and Terraform-module bumps, the page reads as DevOps, not as Infrastructure. The job title on a posting matters less than the artifact set: monorepo, IDP, golden path, internal SDK, build-time metrics. If you carry at least two of those, the page reads as a real platform engineer.

It is the single most recognisable IDP token on the page right now. Roughly two-thirds of US Infrastructure and Platform Engineer postings in 2026 name Backstage by name (Spotify open-sourced it, and a long list of mid-sized engineering orgs adopted it through 2023 to 2025). If you own Backstage at any depth (plugin authoring, Scaffolder template library, Software Catalog ingestion, TechDocs adoption, Cost Insights, custom processors), it goes high on the file with a count: 22 Scaffolder templates, 1,200 services in the catalog, 320 engineers using TechDocs weekly. If your org runs Cortex, Roadie, Port, or OpsLevel instead, name the platform with the same depth signal. Naming Backstage without an owned artifact behind it reads as buzzword padding; the loop will ask which plugin you authored inside the first ten minutes.

Five families of numbers carry the weight on a platform page. Build performance: median and p95 CI times before and after (cut median CI build from 28 minutes to 9, a 68 percent drop), cache hit rate (lifted from 54 to 88 percent), remote-execution farm size. DORA metrics: deploy frequency, lead time for changes, MTTR, change failure rate, ideally as a movement (lifted deploy frequency from weekly to 14 deploys per day on the platform you own). Adoption: engineers using the platform daily, golden-path templates spun up per week, services in the Software Catalog, percent of new services bootstrapped via Scaffolder. Developer experience: internal NPS or platform-CSAT, time-to-first-PR for new hires, time-to-prod for new services. Toil reclaimed: hours per week the platform took off product teams, manual Terraform-bump tickets eliminated, build-incident pages auto-resolved. A bullet that names the platform surface, names the engineer cohort it serves, and lands one of those numbers reads as a real Infrastructure Engineer; phrases like improved developer experience or modernized internal tooling get parsed once and skipped on the second read.
