Job Description:

We are building a high-performance, real-time platform from the ground up, and we need a Backend Architect in the making. At Arosys (LeadAngel) our backend isn’t just a data pipe—it’s the engine room of our entire operation. We are looking for a Node.js expert who lives and breathes asynchronous programming, scalable API design, and cloud-native architecture. As an early hire in a fast-paced startup, you will work side-by-side with our Angular team to build a seamless full-stack experience. If you’re ready to move past “just building features” and want to start building a department, this is the role for you.

Job Responsibility:

  • Architect the Core: Design and implement robust, scalable server-side logic using modern Node.js (v22/24+)
  • API First: Build and maintain high-performance RESTful and/or GraphQL APIs that serve as the backbone for our Angular frontend
  • Data Mastery: Own the database schema design (SQL/NoSQL) and optimize queries for maximum speed and reliability
  • Security & Scalability: Implement industry-standard security protocols (OAuth2, JWT) and ensure the system can handle rapid user growth
  • Lead the Way: Mentor future hires, establish CI/CD pipelines, and contribute to the strategic technical roadmap as we scale toward managerial tiers

Requirements:

  • Node.js Expertise: 2 to 5 years of professional backend experience with a deep understanding of the Node.js event loop and non-blocking I/O
  • Modern Tooling: Proficiency with TypeScript, NestJS (or Express), and modern ORMs
  • Real-time & AI Ready: Experience with WebSockets (Socket.io) or integrating AI model APIs is a huge plus
  • Startup Mindset: You enjoy the “0 to 1” phase. You prefer building clean, reusable systems over patching old ones
  • On-Site Collaboration: You value the energy of a startup office and the speed of in-person brainstorming and whiteboarding

Nice to have:

Real-time & AI Ready: Experience with WebSockets (Socket.io) or integrating AI model APIs is a huge plus

What we offer:
  • Cutting-Edge Stack: No legacy baggage. We use the latest stable versions of Node.js and modern infrastructure
  • Leadership Path: We are looking for a future Head of Engineering. You’ll be groomed for leadership roles as the team grows
  • Direct Impact: Your decisions today will define our architecture for years to come
