Backend Developer with Infrastructure Expertise

Backend Developer with Infrastructure Expertise


Build Scalable Systems. Drive Innovation.

Nexus AI is growing, and we’re looking for a Backend Developer with a solid grasp of infrastructure and scalability to help us expand and refine our client's platform. Our mission is to bridge the gap between AI-driven innovation and real-world business needs, and we need someone who can build reliable, high-performance backend systems to support that vision.


What You’ll Do

  • Expand and optimize our backend services and API using Node.js.

  • Write clean, testable, and efficient JavaScript/TypeScript code.

  • Ensure high availability, security, and performance across our software systems.

  • Monitor and maintain infrastructure, keeping an eye on AWS configurations and EC2 instances.

  • Evaluate and implement the right tools, frameworks, and technologies to keep our system scalable and reliable.

  • Work closely with other developers, with the option to contribute to our React-based frontend if desired.


What We’re Looking For

  • 4+ years of software development experience, with a focus on backend systems. If you don’t meet this but are highly motivated and skilled, let’s talk.

  • Proficiency in Node.js and experience developing scalable web applications.

  • Familiarity with cloud computing platforms (AWS preferred, but any cloud experience works). We care more about deployment expertise than certifications.

  • Experience with Docker and containerization. Orchestration experience is a plus.

  • Strong problem-solving and communication skills.

  • Fluent in English, both written and spoken.


Our Tech Stack

  • CI/CD: GitHub Actions

  • Frontend Deployment: S3 + CloudFront (React)

  • Backend Deployment: Docker containers on AWS EC2

  • Database: MongoDB (Mongo Atlas)

  • Environments: Fully separated Dev and Prod


If you’re excited by the idea of building from the ground up, solving complex challenges, and making a real impact, we want to hear from you.
