Round two of the screen plays out in this section, the closing gate before any interview
is on the table. A recruiter actually takes their time here, and even at that, your
current role still drives roughly 95% of the result.
That tracks: nothing proves what you can run in production today like the seat you sit in
right now. To earn a "yes", this section has to hit every entry on the
MLOps Engineer role profile, one bullet per area named under Domain
Expertise. And every bullet has to come off something you genuinely held in production,
never a Jira card that wandered past your queue.
1
ML Platform Architecture
You build the platform other teams ship their models on. Without it every team reinvents deployment
badly, so hiring managers want to see paths teams actually adopted, not a framework nobody uses. Talk
about how you used golden-path templates and self-serve onboarding, on Kubeflow or SageMaker, to host
more models and cut time-to-production for every team.
Techniques
Multi-tenant design
Self-serve onboarding
Workflow abstractions
Golden-path templates
Tools
Kubeflow, Metaflow
SageMaker, Vertex AI
Ray, Airflow
Metrics
Models hosted
Teams onboarded
Time-to-production cut
2
CI/CD & Model Deployment
You get a model from merged PR to production, hands-free. Hiring managers look here to see whether
models ship like code on your platform, or whether every launch queues behind the platform team. Point
out how you used GitOps deploys and canary rollouts, through ArgoCD and Helm, to raise deploys per week
and shrink rollback MTTR.
Techniques
GitOps deploys
Canary & shadow rollouts
Automated rollback
Progressive delivery
Tools
ArgoCD, Flux
GitHub Actions, GitLab CI
Helm, Kustomize
Metrics
Deploys per week
Lead time for changes
Rollback MTTR
3
Model Registry & Versioning
You own every model's record: versions, lineage, approvals. Lineage coverage and audit results are
binary, checkable facts, so real governance numbers carry more weight than "managed the
registry". Show them how you used artifact versioning and approval gates, in MLflow with DVC, to
get full lineage coverage and pass the compliance audits clean.
Techniques
Artifact versioning
Lineage tracking
Policy & approval gates
Audit & governance
Tools
MLflow, Weights & Biases
SageMaker Registry, Vertex
DVC, Pachyderm
Metrics
Models under registry
Lineage coverage
Compliance audits passed
4
Monitoring, Drift & Observability
You spot trouble across the platform before teams do. Two things ride on it for a hiring manager: drift
caught fleet-wide, and on-call pages that trend down, not up. Lay out how you used platform-wide drift
checks and routed alerts, in Arize with OpenTelemetry, to hold the platform SLO and cut the pages.
Techniques
Data & concept drift
Latency & error budgets
Skew & freshness checks
Alert routing & runbooks
Tools
Prometheus, Grafana
Evidently, WhyLabs, Arize
Datadog, OpenTelemetry
Metrics
Platform SLO hit rate
Drift incidents caught
On-call pages reduced
5
Infrastructure & Compute Orchestration
You squeeze real work out of a shared GPU fleet. Keeping expensive compute busy without teams fighting
over it is the hard part, so hiring managers want utilization you actually delivered. Walk them through
how you used autoscaling with spot capacity, driven by Karpenter on Kubernetes, to save compute dollars
while holding cluster uptime.
Techniques
GPU scheduling & quotas
Autoscaling
Spot / preemptible compute
Multi-cluster topology
Tools
Kubernetes, Kubeflow
Karpenter, Ray, SLURM
Terraform, Pulumi
Metrics
GPU utilization
Compute $ saved
Cluster uptime
6
Reliability, SRE & Incident Response
You make the platform reliable enough to bet a launch on. Hiring managers read that discipline as a
dependable platform, not process for its own sake. Mention how you used SLO design and blameless
postmortems, paged through PagerDuty, to spend less error budget and cut incidents quarter over quarter.
Techniques
SLO & SLI design
Error budgets
Runbooks & postmortems
Chaos & load testing
Tools
PagerDuty, Opsgenie
Statuspage, Incident.io
Chaos Mesh, k6
Metrics
Error budget remaining
Incidents per quarter
MTTR
7
Cross-Functional Collaboration
You run the platform as a product teams choose. Companies keep the platform engineers internal teams
would choose again, not the ones they quietly route around, so hiring managers look for it. Spell out
how you used platform RFCs and onboarding office hours, tracked to internal NPS, to onboard more teams
and cut their ramp time.
Techniques
Platform RFCs
Onboarding office hours
Joint on-call rotation
Internal customer reviews
Tools
Notion, Confluence
Slack, Linear
Jira, GitHub
Metrics
Teams onboarded
DS onboarding time cut
Internal NPS
8
Tooling & Workflow
You let another engineer change the platform safely in week one. Reusable modules and pre-prod testing
keep the platform changeable, so they tell a hiring manager you build it like a product, not a pile of
scripts. Tell them how you used shared IaC modules and Terratest checks, reviewed like any code, to keep
platform PRs moving and onboarding fast.
Techniques
IaC modules & libraries
Internal CLI / SDK
Pre-prod testing
Code review for infra PRs
Tools
Git, GitHub
Terraform, Helm, Kustomize
