Role Overview
You will join a dedicated engineering team responsible for designing, building, and operating backend services and microservices powering a global research platform.
This is a backend‑focused role, centered around Java, Spring, cloud‑native architectures, and modern distributed systems. You will collaborate with engineering squads across Romania, the UK, and the Netherlands, contributing to the evolution of a complex, high‑availability ecosystem.
This position is open exclusively to candidates based in Romania.
Working Model
- Flexible collaboration: Employment (CIM) or B2B
- Location: Romania — remote or hybrid from Cluj / Iași
- Team setup: Cross‑functional engineering teams distributed across RO, UK, and NL
If you’re a senior backend engineer who thrives in modern architectures, enjoys ownership, and wants to build systems used by the global research community, send your profile, and let’s talk.
