We are Evolve Today, a recruitment agency connecting top engineering talent with world‑class opportunities. On behalf of our client — a global organization providing scientific, medical, and analytics information platforms — we are hiring Senior Software Engineers (Node.js & React.js) to build scalable backend services powering an AI‑driven research tool used by scientists, clinicians, and analysts worldwide.
This position is available only for candidates currently residing in Romania.
Project Overview
You will contribute to an AI‑powered research platform that helps users rapidly locate, compare, and summarize evidence from peer‑reviewed scientific literature. The system provides citations, direct links to sources, and supports workflows such as study comparison, evidence synthesis, and drafting research summaries.
Role Overview
This is a backend‑focused engineering role, with occasional frontend contributions. You will design and implement scalable services, APIs, and integrations, ensuring reliability, performance, and clean engineering practices.
We’re looking for senior engineers with 8+ years of experience, strong Node.js expertise, a solid understanding of algorithms and system design, and hands‑on experience building production‑grade systems.
Contract & Working Model
· Flexible collaboration model: employment (CIM) or B2B)
· Location: Romania — remote or hybrid from Cluj / Iași
If you’re a senior backend engineer passionate about building scalable systems and contributing to AI‑powered scientific tools, send your profile and let’s talk.
Responsibilities
· Build and maintain backend services and APIs
· Design and implement REST and/or GraphQL APIs
· Develop business logic and system integrations
· Ensure scalability, reliability, and performance of backend components
· Collaborate with frontend teams to support end‑to‑end delivery
· Write clean, testable, maintainable code
· Participate in system design, architecture discussions, and Agile ceremonies
Requirements
· 8+ years of professional software engineering experience
· Bachelor’s degree in Computer Science, Engineering, or equivalent
· Strong foundation in algorithms, data structures, and core programming concepts
· Strong expertise in Node.js
· Proficiency with TypeScript / modern JavaScript
· Experience designing RESTful APIs and/or GraphQL APIs
· Data modeling experience (SQL / NoSQL)
· Understanding of authentication and authorization concepts
· Experience working with production‑grade systems
· Knowledge of scalability, reliability, and performance best practices
· Experience with unit and integration testing
· Familiarity with Git and Agile workflows
