Be yourself at Protolabs

We are an equal opportunity employer, and we are committed to building a diverse team that feels they are valued in the workplace. So do you feel you do not meet every single requirement but still intrigued? We encourage you to still apply! You can help make our company even better.

We are looking for a Senior Python Developer to join our team in AMS!
This is a hybrid role, and we are accepting applications from candidates based in the Netherlands.
The Manufacturing Partner Marketplace is the operational heart of Protolabs Network. We own the full order lifecycle - matching orders to the right manufacturing partners, moving them through production and quality control, and ensuring on-time delivery. Our work is critical to maintaining seamless operations and customer satisfaction.
Within this domain you'll be building systems that power the marketplace - automated auctions, order allocation, supplier tooling, production workflows, global logistics, quality control, and internal ops tools. We are looking for a pragmatic problem solver who will thrive in a dynamic environment and can take ownership of the business problem, not just the technical solution.
Our Tech Stack
- Backend: Python 3.11+ with FastAPI, Flask and SQLAlchemy (we also use Celery with RabbitMQ for background tasks and KNative for eventing)
- Frontend: Angular 15 with TypeScript
- DevOps: Kubernetes on AWS (using EKS), Terraform, GitHub Actions
- Data: PostgreSQL (on RDS), Redis (using Elasticache)
- Integrations: Retool and Zapier
- (Some teams also use Rust, Java, and C++)
