Edtech.com's Summary

Open LMS is hiring a Cloud Infrastructure Engineer (Open LMS) Colombia to help build, scale, and evolve the multi-tenant SaaS hosting platform that powers hundreds of Moodle LMS instances for education clients. The role sits deep in the infrastructure stack, spanning Terraform, Puppet, and Python automation rather than containerized tooling. Real ownership over the platform's architecture comes with the position as the team continues to grow it.

Highlights

Designs and maintains AWS infrastructure via Terraform, covering EC2, RDS, S3, SQS, Lambda, ALB, ElastiCache, Route 53, and VPC networking.
Writes and maintains Puppet modules to configure fleets of EC2 instances across multiple auto-scaling groups.
Builds and extends Python-based automation and production daemons that support platform operations.
Operates and improves distributed service discovery and configuration management through etcd.
Tunes a multi-tier caching strategy spanning Varnish, Redis/Valkey, and PHP OPcache.
Runs and scales an observability stack built on Prometheus, Grafana, Loki, Fluentd, and PagerDuty, including on-call rotations.
Leads incident response, root cause analysis, and ongoing platform reliability work.
Requires deep Linux (Ubuntu) systems knowledge alongside a solid grasp of distributed systems concepts like consensus, leader election, and distributed locking.
Works within a GitLab-based CI/CD workflow and documents architectural decisions for both technical and non-technical stakeholders.
Evaluates distributed storage options such as Ceph, GlusterFS, or AWS EFS as the platform scales.

Cloud Infrastructure Engineer (Open LMS) Colombia Full Description

Role Description

We are looking for a Senior Cloud Infrastructure Engineer to join our team and help build, scale, and evolve our multi-tenant SaaS hosting platform on AWS. Our platform dynamically provisions, manages, and scales hundreds of Moodle LMS instances for education clients — powered by custom orchestration tooling, distributed service discovery, and infrastructure as code.

This is a hands-on infrastructure role. You'll work across the full stack — from Terraform modules and Puppet manifests to Python automation and observability pipelines. The platform is not containerised — there is no Kubernetes here — so we're looking for someone who understands Linux systems deeply and can reason about distributed systems problems from first principles.

You'll have real ownership and influence over the platform's architecture and direction as we continue to grow and evolve the infrastructure.

What You'll Be Doing

Designing, building, and maintaining AWS infrastructure using Terraform (EC2, RDS, S3, SQS, Lambda, ALB, ElastiCache, Route 53, VPC networking)
Writing and maintaining Puppet modules to configure and manage fleets of EC2 instances across multiple auto-scaling groups
Maintaining and extending Python-based automation and tooling that supports platform operations
Operating and improving distributed service discovery and configuration management (etcd)
Managing and tuning a multi-tier caching strategy (Varnish, Redis/Valkey, PHP OPcache)
Running and scaling our observability stack (Prometheus, Grafana, Loki, Fluentd, PagerDuty) and participating in on-call rotations
Evaluating and implementing distributed storage solutions as the platform evolves
Improving deployment workflows and release processes
Collaborating with internal teams on API contracts, integration patterns, and operational tooling
Participating in incident response, root cause analysis, and platform reliability improvements

Skills and Aptitudes

Strong experience with AWS services in production — particularly EC2, RDS, S3, SQS, Lambda, ALB, ElastiCache, Route 53, IAM, and VPC networking
Proficiency in authoring and maintaining Terraform modules for production infrastructure
Proficiency in authoring and maintaining Puppet modules (or equivalent agent-based configuration management) for fleet management
Solid Python skills — you'll be writing and maintaining production daemons, not just scripts
Deep Linux systems knowledge (Ubuntu) — comfortable with Apache/Nginx, PHP-FPM, Varnish, systemd, filesystem mounts, and networking fundamentals
Understanding of distributed systems concepts: consensus, leader election, distributed locking, eventual consistency, and the tradeoffs involved
Proficiency in building and maintaining observability pipelines (Prometheus, Grafana, Loki, or equivalent) in production
Comfortable working in a GitLab-based CI/CD workflow
Clear communicator who can document architectural decisions and explain technical tradeoffs to both technical and non-technical stakeholders

Additionally, a Top Candidate Will Exhibit One or More of the Following Preferred Qualifications

Hands-on experience with distributed storage systems such as Ceph, GlusterFS, JuiceFS, CubeFS, or AWS EFS — particularly in the context of migration or evaluation
Familiarity with etcd (or similar distributed key-value stores like Consul or ZooKeeper) including watch APIs, TTL-based locking, and cluster operations
Experience with Varnish and VCL, especially dynamic backend routing or multi-tenant configurations
Working knowledge of PHP — not to build applications, but to understand and maintain integration scripts that bridge infrastructure and application layers
Background in multi-tenant SaaS platform design — particularly database-per-tenant models on shared infrastructure
Familiarity with Moodle LMS or education technology platforms
Experience with secrets management solutions (AWS Secrets Manager, HashiCorp Vault, Parameter Store) and automated credential rotation
Experience designing zero-downtime deployment strategies for VM-based (non-containerized) environments
