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
The flagship work of the role. Lay out the platform you designed, the model count it now
hosts, plus the team count shipping on top of it. State what the platform enabled, never
"built an ML platform".
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
How a model PR becomes live traffic. Describe the pipeline you wired between commit and
production, the rollback story behind a bad deploy, plus the deploy cadence you unlocked.
Cite the deploy frequency and what it released for data science, not "wired CI/CD".
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
Where artifact, lineage, plus governance all sit. Describe the registry you run, the
lineage you track from data to model to deploy, plus the policy gates a model has to clear
before going live. Name the registry and what it now enforces, not "used a model
registry".
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
Platform-level eyes on every model the org runs. Cover the drift detection you wired in,
the dashboards every model on the platform gets for free, plus the incident you caught
before users felt it. Numbers do the work here: drift incidents caught, paged on-calls
reduced, SLO hit rate.
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
The compute substrate everyone's models run on. Show the cluster you sized, the GPU
pool you scheduled, plus the cost win you booked. Name the workload, the cluster, plus
what the org spends now, not "managed GPU infra".
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
What separates an ML platform from a shared notebook. Detail the SLOs you set with data
science, the runbooks you wrote, plus the incident you led the response on. Cite the
error budget held and what the team learned from a postmortem, not "handled
incidents".
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
MLOps Engineers run nothing on their own. Cover how you partnered with Data Science on the
deploy interface, ML Engineering on the registry contract, plus SRE on platform on-call.
Spell out what the partnership produced, never simply who was in the room.
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
The platform engineering workflow that keeps yak-shaving off everyone's plate. Cover
the IaC you wrote, the internal CLI or SDK you exposed, plus the review patterns that
catch a bug before it reaches a tenant. Name what you actually use, never "a modern
stack".
Techniques
IaC modules & libraries
Internal CLI / SDK
Pre-prod testing
Code review for infra PRs
Tools
Git, GitHub
Terraform, Helm, Kustomize
pytest, Terratest
Metrics
Infra modules maintained
Platform PR cycle time
Onboarding ramp time cut
