About the Role:

In the role of Cloud Infrastructure Engineer you will be responsible for building, shipping, and maintaining complex infrastructure at scale. The Mendix Cloud hosts tens of thousands of mission-critical customer applications, powering anything from insurance quotes, to ensuring that PostNL can deliver millions of parcels on time.

Specifically, you will be part of the team running the core infrastructure powering the Mendix Public Cloud. The Mendix Public Cloud has 4 primary components:

- Compute - using Kubernetes for our PaaS container orchestration, with AWS EC2 underneath

- Database - using AWS RDS

- Storage - Amazon S3

- Networking - Nginx both self-hosted and Kubernetes Ingress Controller

On top of this, there are various microservices, developed in house, that handle provisioning of these services, entitlement, and upgrades. These are written primary in Golang and a couple in Python.

The core infrastructure team is responsible for this infrastructure, spread across 10 production deployments across the globe, 24/7, with 4 nines of uptime. Our infrastructure is managed using Terraform (for IaC), GitLab CI and monitored using Prometheus and Datadog. Currently we are in the process of migrating our applications from CloudFoundry to Kubernetes.

We're looking for you if:

• You are strong infrastructure engineer with speciality in networking.
• You have strong networking fundamentals (DNS, subnets, VPN, VPCs, security groups, NATs, Transit Gateway etc)
• You have extensive and deep experience (~4 years) with IaaS Cloud Providers. AWS is ideal, but GCP/Azure would be fine too.
• You have experience with running cloud orchestration technologies like Kubernetes and/or Cloud Foundry, and designing highly resilient architectures for these.
• You have strong knowledge of Unix/Linux fundamentals.
• You have experience with infrastructure as code tools. Ideally Terraform, OpenTofu but CloudFormation or Pulumi are fine too.
• You have experience designing cross Cloud/on-prem connectivity and observability
• You have a DevOps mindset: you build it, you run it.
• You care about code quality, and know how to lead by example: from a clean Git history, to well thought-out unit and integration tests.

Even better (but not essential!) if you have experience with:

• Monitoring tools that we use, such as Datadog and Prometheus
• CI/CD tooling such as GitLab CI
• You have programming experience with (ideally) Golang or Python
• You are willing and able to use your technical expertise to mentor, train, and lead other engineers

You’ll help drive digital innovation by:

• Continually improving our security + operational excellence.
• Work directly with customers to set up connectivity between Mendix Cloud platform and customers backend infrastructure.
• Rapidly scaling our infrastructure to match our rapidly increasing customer base.
• Continuously improving the observability of our platform, so that we can fix problems before they occur.
• Improving our automation and surrounding tooling to further streamline deployments + platform upgrade.
• Improving the way we use AWS resources, and defining cost optimization strategies.

Here are many of the tools we make use of:

• Amazon Web Services (EC2, Fargate, RDS, S3, ELB, VPC, CloudWatch, Lambda, IAM, and more !)
• PaaS: (Open Source) Kubernetes, Docker, Open Service Broker API
• Monitoring: Prometheus, InfluxDB, Grafana, Datadog
• CI/CD: GitLab CI, ArgoCD
• Automation: Terraform, Helm
• Programming languages: mostly Golang and Python, with a sprinkling of Ruby and Lua
• Scripting: Bash, Python
• Version Control: Git + GitLab
• Database: PostgreSQL
• Webserver: nginx, Kong

If you see a job description and think, “I’d be perfect for that” but your experience doesn’t align perfectly with the qualifications – don’t let that hold you back. We’re always eager to hire talented, passionate candidates – so give it a try and apply.
