This is where the second pass actually plays out, the last gate before an interview hits your
inbox. The recruiter slows down right here, and even then your current role still drives
around 95% of the decision.
Makes sense: nothing tells a hiring team what you can run in production right now the way your
current job does. To clear that "yes", this section has to walk the full
Platform Engineer role profile, one bullet per slot you listed in Domain
Expertise above. Every bullet has to come off something you actually held in production,
not a Jira card that wandered past your queue.
1
IDP Architecture
The flagship work of the role. Show the Internal Developer Platform you designed, the
paved-road capabilities under it, and the application teams now shipping on top. Name the
platform and what it enabled, not "built a platform".
Techniques
Platform-as-a-Product
Platform capability map
Tenant model
Discovery interviews
Tools
Backstage
Port, Cortex
Kratix
Metrics
Application teams onboarded
Time-to-first-deploy cut
Platform NPS
2
Golden Paths & Templates
The paved roads that turn a new service from a tutorial into a production-ready repo on
day one. Show the templates you authored, the CI/CD wiring inside them, and the percentage
of new services that ship through them. Name the templates and the patterns they
standardize, not "wrote templates".
Techniques
Service templates
Software templates (Backstage)
Baked-in SLOs & observability
Repo bootstrapping
Tools
Backstage scaffolder
Cookiecutter, Yeoman
Helm, Kustomize
Metrics
Services on paved road
Templates maintained
Bootstrap time cut
3
Developer Portal & Self-Serve Catalog
The product surface application teams actually use. Show the portal you stand up (Backstage
or equivalent), the catalog of resources behind it, and the self-serve workflows you
exposed (request a database, spin up an environment, claim a cluster). Name the portal and
the workflows behind it, not "set up Backstage".
Techniques
Service catalog

Self-serve workflows
Catalog ingestion
Tools
Backstage
Port, Cortex
OpsLevel
Metrics
Weekly active developers
Catalog entities
Self-serve requests fulfilled
4
CI/CD & Release Engineering
The pipeline layer underneath the paved roads. Show the CI/CD platform you standardized
on, the progressive-delivery setup baked into every golden path, and the deploy frequency
it unlocked across application teams. Name the platform and what the templates wire in,
not "set up CI/CD".
Techniques
GitOps
Progressive delivery
Reusable workflows
Policy as code
Tools
GitHub Actions
Argo CD / Flux
Tekton, Flagger
Metrics
Deploy frequency
Lead time for changes
Change-failure rate
5
Infrastructure Abstractions & Platform APIs
How Platform Engineering hides infra complexity behind a clean developer API. Show the
Crossplane (or Kratix, or operator) abstractions you wrote, the resource claims developers
make, and the underlying cloud or Kubernetes primitives they replace. Name the API and the
primitive it abstracts, not "used Crossplane".
Techniques
CRDs & operators
Resource claims
Composition functions
Policy boundaries
Tools
Crossplane
Kratix
Operator SDK
Metrics
Resource types exposed
Claims served
Ticket queue reduced
6
Developer Experience & Productivity
How the platform proves it earns its keep. Show the DORA or SPACE dashboard you stood up,
the DX research you ran (surveys, interviews, friction logs), and the experiment that
shifted a metric. Cite the metric you moved and what it unlocked, not "measured
DX".
Techniques
DORA, SPACE
Developer surveys
Friction logs
Product discovery
Tools
DX, Jellyfish, Swarmia
Grafana / Looker dashboards
Linear, Notion
Metrics
Time-to-first-deploy
Developer NPS
DORA elite hit rate
7
Platform Operations & Reliability
What keeps the IDP itself trusted by application teams. Show the SLOs you wrote for the
platform, the on-call rotation behind it, and the incident you led for a platform outage.
Name the SLO and the rotation, not "ran platform on-call".
Techniques
Platform SLOs
Tier definitions
Capacity planning
Incident command
Tools
Prometheus / Grafana
PagerDuty
OpenTelemetry
Metrics
Platform SLO hit rate
MTTR cut
Pages per shift down
8
Tooling & Workflow
The setup that lets a small platform team serve hundreds of developers. Show the platform
RFCs you run, the contribution model you opened (inner-source contributions to the IDP),
and the docs that cut onboarding ramp. Name the workflow, not "a modern stack".
Techniques
Platform RFCs
Inner sourcing
Office hours
TechDocs
Tools
Git, GitHub
Python, Go, TypeScript
OpenAPI / GraphQL
