We’re looking for a Java Software Engineer (Remote) to join our team.

This position is remote & open to applicants based in the EU.

We are looking for a Java software engineer to join the Product Operations team at Protolabs, where our mission is to revolutionise our workflow and drive efficiency as we continue our scaling journey. The team is responsible for streamlining processes - from allocating orders to our manufacturing partners, navigating production stages, managing communications and quality controls, orchestrating shipping & logistics, and ensuring timely payments.

In the past, we moved fast with bespoke tools that improved shipping & logistics but left a fragmented landscape. As we scale globally, we are unifying these capabilities and establishing Logistics as a first‑class domain within our product and engineering ecosystem.

This is a true zero-to-one effort. You will ship early, small slices of value - balancing speed with durable foundations for scale and reliability.

Tech environment

For this role: Java microservices with Spring Boot; REST/async APIs; PostgreSQL; Redis; Docker/Kubernetes; CI/CD with GitHub Actions; observability and logging. RabbitMQ & KNative for eventing

The broader ecosystem you will integrate with: Python services (FastAPI/Flask with SQLAlchemy and Celery), Angular (TypeScript) frontends, Terraform, Docker, k8s for infrastructure, Retool and Zapier for operational tooling. Some internal teams also use Rust and C++.

What’ll you do

Ship business value fast: design, implement and release thin slices that reduce manual work, improve on‑time shipments, increase logistical visibility, and shorten cycle times
Build and integrate Java-based microservices and APIs: expose secure, well-documented endpoints and integrate with eventing systems
Make pragmatic architectural calls: design data contracts and integration approaches that balance speed with long‑term maintainability
Establish foundations: set up CI/CD, automated tests, observability and SLOs to ensure reliability from day one
Streamline operations: automate exception handling and reconciliations, retire legacy scripts/tools, and remove bottlenecks across the order‑to‑ship flow
Collaborate and influence: work closely with Product Ops, stakeholders, and contribute and participate in our Backend Guild
Own end‑to‑end delivery: discovery, design, build, deploy, monitor, iterate—and handle production issues to keep value flowing

What it takes

5+ years of experience building web applications and backend services, with at least 3 years of experience in using Sprint Boot in a (micro)services environment
Proficiency in Java for designing, developing, testing, and monitoring production systems
Experience with relational databases (like PostgreSQL)
Familiarity with Docker, Kubernetes, and CI/CD environments
Experience working in an agile team, and excellent communication and collaboration skills

Bonus point for:

Deep understanding of event-based architectures
Familiarity with Angular
Comfort reading and understanding Python code

Nice to have

Knows and understands basic concepts and procedures in one of the development disciplines
Strong verbal and written communication skills
Excellent work ethic, positive attitude and sense of urgency
