- AIMMS Cloud Platform is an AWS application (set of 10 Docker services);
- It is multi-tenant, we currently have tens of customers and the number is growing every week;
- It originates from an on-premise solution that is used publishing and deployment of AIMMS applications;
- We’re still supporting that on-premise product, but our main focus is at the Cloud.
What are the challenges we solved recently?
- Moved our big on-premise solution to the Cloud (AWS, Docker);
- Automated Cloud setup so that we can spin up new accounts within minutes (Python, CloudFormation);
- Started splitting that monolith into microservices (Java, Spring, Spring Boot);
What are the upcoming challenges for this year?
- Evaluate using Kubernetes (currently we’re using ECS for orchestration);
- Extract more microservices;
- Make our Cloud platform even more scalable and reliable.
How does our code look like?
- Our team covers everything that is related to our product: design, development, testing, release management and deployment;
- We have unit and integration tests in place. Our test coverage is low (around 50%), but we’re working on it;
- We’re using GitLab both as version-control system and CI/CD. Everything’s automated. You can push a commit and in 15 minutes you will have a build with all relevant tests executed;
- We have scripts (and UI) for deployment. A hotfix can be (and sometimes is) deployed to production within 30 minutes after the commit.
What do we offer?
- Flexible working hours with possibility to work from home
- A quarterly 2-days Hackathon
- No managers. We use Holacracy as operating system
- Daily lunch & fresh fruits
- A competitive salary
- Fully paid pension
- 6 weeks of holiday per year
- Annual performance-based bonus
- Annual training & conference budget
- 15-min train ride from Amsterdam Centraal Station (travel cost covered)
Why choose AIMMS?
- Software engineering challenge. For our cloud platform multiple services written in Java run in a mix of multi-tenant and single-user Docker containers on multiple AWS ECS clusters. The single-user Docker containers are launched on-demand to run custom AIMMS applications. We often exceed 99.98% up-time (incl. planned downtime for updates) and have already hit 100.0% a number of times. We keep strengthening our security and are continuously being monitored by large enterprise customers, external pen-testers and automatic scanning services.
- Our culture. We are proud of our culture and believe it is special. It is about people, about trust, about valuing differences and about the combination of performance and care. Read in our latest Culture Book what AIMMSians write about it.
- Holacracy. We are self-organized, using Holacracy. No managers. Plenty autonomy and transparency. Quick adjustments of organization, roles and accountabilities. A place where you can develop yourself to your full potential.

- You know when to prefer microservices over monolith solution and vice-versa
- You’re keen to build cloud-native applications
