Resumen del rol

Buscamos un/a DevOps Engineer con dominio de AWS y Terraform para diseñar, automatizar y operar infraestructura y pipelines de entrega en un entorno IoT/OT industrial. El CI/CD se realiza exclusivamente con GitHub Actions.

El rol integra datos desde planta (KEPServerEX/Kepware en Windows – OPC UA/DA) hacia la nube, operando componentes edge en Linux con AWS IoT Greengrass v2 y modelado/ingesta industrial con AWS IoT SiteWise, utilizando una capa de streaming para la ingesta. El objetivo es asegurar seguridad, observabilidad y resiliencia end-to-end.

Arquitectura (alto nivel)

  • Planta/OT: KEPServerEX (Windows) expone tags vía OPC UA/DA
  • Edge: Gateway Linux con AWS IoT Greengrass v2 (normalización, buffering, store-and-forward)
  • Streaming: publicación a capa streaming (Kinesis/MSK o IoT Core Rules streaming) con backpressure y retries
  • Cloud: consumidores procesan/enriquecen e ingieren a AWS IoT SiteWise + observabilidad/almacenamiento complementario

Responsabilidades

  • IaC (Terraform): diseñar y mantener infraestructura AWS (módulos reutilizables, remote state/locking, multi-entorno dev/stg/prod, naming/tagging).
  • Estandarización de IaC: estructura de repos, versionado de módulos, estrategia de cambios vía PRs y trazabilidad.
  • CI/CD (GitHub Actions – exclusivo): workflows para fmt/validate/plan/apply, approvals por ambiente, despliegues controlados; reusable workflows/composite actions.
  • Seguridad en pipelines: OIDC/assume-role, gestión de secretos (Secrets Manager/Parameter Store), controles automáticos (secret scanning, policy/IaC scanning si aplica).
  • Edge (Greengrass en Linux): empaquetar/desplegar/actualizar componentes, operación del runtime, hardening, observabilidad y manejo de conectividad intermitente.
  • Integración con KEPServerEX (Windows): coordinación con OT (permisos/conectividad), mapeo de tags, troubleshooting OPC UA/DA y performance.
  • Streaming a cloud: publicación confiable (idempotencia, retries, orden/ventanas si aplica), monitoreo de lag/throughput/errores, DLQ y reprocesos.
  • AWS IoT SiteWise: soporte en modelado de activos (asset models), jerarquías y propiedades; monitoreo de ingesta/latencia/calidad; alertas/tableros.
  • Observabilidad end-to-end: métricas, logs, alertas y dashboards (CloudWatch y herramientas complementarias).
  • Operación e incidentes: RCA/postmortems, automatización de runbooks, mejora continua; participación en guardias si aplica.
  • FinOps: tagging/cost allocation, budgets/alerts, optimización de costos (retención de logs/datos, rightsizing).

Requisitos (Must-have)

  • Experiencia sólida en AWS (redes, seguridad, operación e integración de servicios).
  • Dominio práctico de Terraform (módulos, remote state, entornos, import/migraciones, buenas prácticas).
  • Experiencia comprobable con GitHub Actions (workflows, environments, runners, secrets, reusable workflows, approvals).
  • Operación Linux (edge) + conocimientos de Windows para interoperar con KEPServerEX; scripting Bash y/o Python.
  • Conocimiento práctico de streaming y patrones de confiabilidad (retries, DLQ, backpressure, idempotencia).
  • Buen manejo de Git (PRs, code review, branching).
  • Seguridad: IAM least privilege, KMS, segmentación de red, gestión de secretos y auditoría.

Deseables

  • Experiencia directa con AWS IoT Greengrass v2 y/o AWS IoT SiteWise.
  • Kinesis/MSK e integración con consumers (Lambda/ECS/EKS).
  • Conocimiento de SCADA/PLC/OPC y troubleshooting en redes industriales.
  • Observabilidad avanzada (Grafana/Prometheus, ELK/OpenSearch, Datadog).
  • Certificaciones AWS o Terraform Associate.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
