Wizdaa Inc.; Argentina; Remote; ARS 181,906,000 - 272,860,000; Full time

Job summary

Wizdaa Inc. seeks a Platform Architect to set the standard for ML and AI infrastructure at scale. You will bridge ML infrastructure and SRE, owning deployment pipelines, model serving reliability, and cost-aware multi-tenant orchestration on GKE.

You’ll champion IaC, Terraform, GitOps, and CI/CD for reproducible pipelines, with strong GCP experience and a focus on production-grade ML systems. Remote LATAM, USD payments, EST hours.

Qualifications

• 5+ years in platform engineering, SRE, MLOps, or infrastructure at scale.
• Hands-on experience deploying ML/AI workloads in production: serving, inference, or training.
• Strong SRE/DevOps foundation with measurable reliability improvements.
• Deep Terraform expertise with multi-project configurations and CI-driven workflows.
• GitOps in production (ArgoCD or Flux) with declarative infra management.
• Kubernetes production experience (GKE, with multi-tenant considerations) and cost awareness.
• Strong GCP background: VPC, Compute Engine, IAM, Cloud Storage; BigQuery production usage.
• Hands-on experience with CI/CD pipelines and ML pipelines (GitHub Actions, Cloud Build, etc.).
• Automation-first mindset; ability to reduce manual work and improve toil.
• Excellent communication to explain operational decisions and trade-offs.

Responsibilities

• Build and operate model and inference serving infrastructure for real-time and batch workloads.
• Own ML deployment lifecycle: registry, versioning, promotion, canary/shadow rollout, rollbacks.
• Manage agentic/LLM workloads, gateways, quotas, guardrails, and graceful degradation.
• Create reproducible ML pipelines as code, with lineage and reproducibility built in.
• Extend IaC to ML systems using Terraform patterns and multi-project design.
• Operate GitOps for ML workloads with ArgoCD across environments and tenants.
• Run ML workloads on multi-tenant Kubernetes (GKE) with GPU scheduling and tenancy isolation.
• Define SLOs for inference services and monitor data/model drift and incident response.
• Drive ML cost efficiency via right-sizing accelerators and cost attribution across tenants.
• Review agentic tooling outputs to multiply engineering productivity.

Job description

we're looking for a Platform Architect who can set the standard for how we build, ship, and operate ML and AI systems at scale. You sit at the intersection of ML infrastructure and SRE. You'll own the path from model and pipeline to reliable production service, and you'll bring DevOps rigor to systems that are historically under-engineered. The immediate focus is AI/ML infrastructure on Google Cloud. This is not a ticket-processing role, and it's not a research role. You'll tackle hard problems: model serving reliability, inference cost and latency, reproducible pipelines, and agentic workload operations. You'll have the scope to solve them properly. Senior professionals here identify problems before they're asked and raise the ceiling on what the platform can do.

WHAT YOU'LL WORK ON

• Build and operate model and inference serving infrastructure, managing latency, throughput, autoscaling, and reliability for real-time and batch inference across multiple tenants.
• Own the ML deployment lifecycle: model registry, versioning, promotion workflows, rollout strategies (canary, shadow, A/B), and safe rollback.
• Operate agentic and LLM workloads in production, managing inference providers and gateways, quota and throttling behavior (TPS/TUPS limits), guardrails, prompt/version management, and graceful degradation under load.
• Build reproducible, automated ML pipelines: training, evaluation, and deployment pipelines as code, with lineage and reproducibility built in.
• Extend infrastructure-as-code to ML systems, using Terraform patterns and multi-project design that bring ML infrastructure under the same standards as the rest of the platform.
• Operate GitOps for ML workloads, owning ArgoCD configuration and promotion workflows across environments and tenants.
• Run ML and AI workloads on multi-tenant Kubernetes (GKE), managing GPU/accelerator scheduling, workload placement, tenant isolation, and cost-aware capacity.
• Own ML reliability and observability: SLOs for inference services, model and data drift detection, performance regression monitoring, alert quality, on-call ergonomics, and runbook culture.
• Drive ML cost efficiency by right-sizing accelerators, managing committed-use and Spot VM capacity, and attributing inference cost across tenants and workloads.
• Use agentic coding tools for infrastructure and pipeline work: scaffolding environments, generating and reviewing IaC and pipeline code, and accelerating automation.

WHAT YOU WON'T FIND HERE

A platform team that maintains the status quo. We're actively building: new scale requirements, new architectural domains, and an ML/AI footprint that's growing fast. Senior engineers here shape how the platform evolves, and the tools available to do it are better than they've ever been.

Requirements MUST HAVE

• 5+ years in platform engineering, SRE, MLOps, or infrastructure, with meaningful time operating production systems at scale.
• Hands‑on experience deploying and operating ML or AI workloads in production: serving, inference, or training infrastructure that real users depended on.
• Strong SRE/DevOps foundation. You've owned reliability for production services, defined and measured SLOs, run post‑mortems, and driven measurable improvements.
• Deep Terraform expertise. You actively manage complex Terraform state, reusable modules, and multi‑project configurations in production, with CI‑driven plan/apply workflows.
• Strong GitOps background (ArgoCD or Flux in production). You understand declarative infrastructure management at depth and have opinions on how to do it well.
• Deep Kubernetes knowledge. You've operated clusters in production, dealt with real failure modes, and understand the system at the control plane level. Production GKE experience (Standard and/or Autopilot) is strongly preferred.
• Strong GCP background: VPC networking, Compute Engine, IAM, Cloud Storage, and multi‑project/organization design.
• Hands‑on experience with GCP data services, especially BigQuery in production: partitioning and clustering, query cost and performance tuning, and dataset‑level IAM. Familiarity with at least one of Dataflow, Pub/Sub, or Dataproc.
• Hands‑on experience building and operating CI/CD pipelines (GitHub Actions, Cloud Build, GitLab CI, or equivalent), plus an understanding of how ML pipelines differ from standard application CI/CD.
• Automation‑first thinking at a senior level. You implement systems that eliminate entire categories of manual work.
• Active user of agentic coding tools. You know how to direct them effectively, review their output critically, and use them to multiply your output.
• Strong communicator. You can articulate operational decisions, model performance trade‑offs, and incident summaries clearly to engineers and leadership alike.

NICE TO HAVE

• Experience with GPU/accelerator scheduling and node lifecycle management in production (e.g., GKE node auto‑provisioning, GPU time‑sharing, or equivalent).
• Experience operating LLM inference at scale, managing provider quotas/throttling (TPS/TUPS), gateways, caching, and guardrails (e.g., Vertex AI, Gemini API, or equivalent).
• Experience with ML pipeline and orchestration tooling such as Argo Workflows, Kubeflow, Cloud Composer/Airflow, Vertex AI Pipelines, or equivalent.
• Experience with model registries, feature stores, and experiment tracking (e.g., MLflow, Feast, or equivalent).
• Familiarity with model and data drift monitoring and ML‑specific observability.
• Background in FinOps: inference cost attribution, committed use discount (CUD) and reservation planning, and accelerator capacity forecasting.
• Familiarity with data infrastructure such as object storage, CDC pipelines, or lakehouse patterns.
• Experience with multi‑tenant infrastructure: isolation patterns, noisy neighbor mitigation, and tenant lifecycle management.
• Prior experience scaling ML or platform infrastructure at a startup moving toward enterprise‑grade requirements.
