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., * 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 ## Related Videos - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Post-Quantum Cryptography: Preparing for Q-Day](https://www.wearedevelopers.com/videos/100179-post-quantum-cryptography-preparing-for-q-day) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [Seriously gaming your cloud expertise: from cloud tourist to cloud native](https://www.wearedevelopers.com/videos/373-seriously-gaming-your-cloud-expertise-from-cloud-tourist-to-cloud-native) - [Streaming AI Responses in Real-Time with SSE in Next.js & NestJS](https://www.wearedevelopers.com/videos/1630-streaming-ai-responses-in-real-time-with-sse-in-next-js-nestjs) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [The Best Job Search Websites of 2025](https://www.wearedevelopers.com/magazine/368-the-best-job-search-websites-of-2025)
