Career roadmap

MLOps / AI Platform Engineer

Own the runway: training infrastructure, model serving, GPU cost, monitoring, and rollback for everything AI teams ship.

Time
6-10 months part-time

Before you start MLOps

  • Linux and networking
  • Docker
  • Python
  • One cloud and its IAM model
  • CI/CD experience

Infrastructure fundamentals

6-8 weeks · 0/5 topics

Reproducible infrastructure, defined in code.

  1. Clicking in a console is not a platform.

    • State and locking
    • Modules
    • Plan review in CI
    • Drift detection
  2. The substrate most ML platforms run on.

    • Deployments and services
    • Requests and limits
    • HPA and node pools
    • GPU device plugins
  3. Least privilege, and no credentials in a container image.

    • Workload identity
    • Secret managers
    • Network boundaries
    • Audit logging
  4. Deploys must be boring and identical every time.

    • Pipeline as code
    • Environment promotion
    • Artefact immutability
  5. You cannot control a bill you cannot attribute.

    • Tagging conventions
    • Budget alerts
    • Idle resource reaping

BuildA Terraform-defined cluster a teammate can recreate from scratch with one command.

Model lifecycle

6-8 weeks · 0/4 topics

Any training run must be reproducible six months later.

  1. Runs, params, metrics, artefacts — in one place, automatically.

    • MLflow or W&B
    • Run metadata conventions
    • Comparing runs
  2. The contract between the people who train and the people who serve.

    • Stages and promotion
    • Approval gates
    • Model cards
    • Rollback to a prior version
  3. Same code plus different data is a different model.

    • DVC / LakeFS
    • Immutable dataset snapshots
    • Lineage from data to model
  4. Pinned everything, seeds fixed, container digest recorded.

    • Lockfiles and base images
    • Deterministic seeds
    • Recording the commit with the run

BuildA pipeline that reproduces a past training run from a commit hash.

Serving & GPUs

6-8 weeks · 0/5 topics

Serve models fast, and know the cost per thousand requests.

  1. vLLM for LLMs, Triton or TorchServe for the rest.

    • vLLM basics
    • Triton model repositories
    • Concurrency and queueing
    • Health checks
  2. The two levers that decide GPU throughput for LLM serving.

    • Continuous batching
    • KV cache memory maths
    • Prefix caching
    • Max sequence length trade-offs
  3. Cheaper inference, measured against an eval set — never assumed.

    • INT8 / FP8 / AWQ / GPTQ
    • Quality regression testing
    • Latency vs accuracy curves
  4. GPUs are the most expensive idle resource you will ever own.

    • Scale-to-zero and cold starts
    • Queue-depth based scaling
    • Spot and preemptible strategies
    • Multi-tenancy / MIG
  5. Answer this with a spreadsheet, not an opinion. You will be asked.

    Ch 87 — Cost & Latency Optimization
    • Break-even volume
    • Utilisation assumptions
    • Engineering time as a cost
    • Compliance drivers

BuildA self-hosted open model behind an autoscaling endpoint, with throughput, p95 latency, and cost per 1k requests reported.

Observability & safe release

4-6 weeks · 0/5 topics

Catch the regression before the customer writes in.

  1. Model services need the same three pillars as any service, plus quality signals.

    • Prometheus and Grafana
    • Request tracing
    • Token and cost metrics
    • SLOs for an AI endpoint
  2. Inputs change before outputs visibly break. Watch the inputs.

    • Input distribution monitoring
    • Prediction drift
    • Proxy quality metrics
    • Alert fatigue control
  3. A quality bar the deploy pipeline enforces, with a tolerance you chose deliberately.

    Ch 85 — Evaluation & Hallucination
    • Baseline comparison
    • Tolerances that neither block everything nor nothing
    • Blocking a merge
  4. 5% of traffic, a watched window, then promote or revert automatically.

    • Traffic splitting
    • SLO watch windows
    • Automatic rollback
    • Blue/green for weights
  5. Model failures need runbooks too — and a written post-mortem.

    • Severity levels
    • Runbooks per service
    • Post-mortems and guardrails added

BuildA canary deploy that rolls back automatically when an eval gate or latency budget fails.

Governance & cost

4 weeks · 0/4 topics

The questions finance and compliance will ask, answered in advance.

  1. What the model is, what it was trained on, who approved it.

    • Model card contents
    • Approval records
    • Change history
  2. Prompts, datasets, and weights are all sensitive assets.

    • Role-based access
    • Prompt and dataset permissions
    • Weight exfiltration risk
  3. Per-team visibility, and a hard stop before the quarter is gone.

    • Attribution by team and model
    • Quota enforcement
    • Chargeback reporting
  4. Inference logs contain user data. Decide the window before legal asks.

    • Retention windows
    • PII scrubbing in logs
    • Region constraints

BuildA cost dashboard broken down per model and per team, with an enforced quota.

MLOps tools on your CV

  • Terraform
  • Kubernetes
  • MLflow
  • vLLM or Triton
  • Prometheus + Grafana
  • GitHub Actions
  • A cloud with GPU quota

What MLOps employers ask to see

  • A repo that stands the platform up from zero
  • A cost-per-request number you reduced, with the method
  • An incident write-up with the guardrail you added

Demand follows AI adoption with a lag — companies hire this once models are in production and the bill arrives. The natural move for DevOps and SRE engineers; if you already run Kubernetes, you are most of the way there.
