Senior Back-End Developer (JS)
We are looking for a seasoned and focused Senior Back-End Developer to take ownership of the critical server-side architecture and services for our Cybersecurity SaaS platform.

This role is highly concentrated on Node.js back-end development, secure API design, and database management.

While your primary focus is the server, you must have strong working knowledge of the React.js/Next.js front-end ecosystem to ensure seamless integration and performance of our services.
Key Responsibilities
API & Core Services Development (Back-End Focus) ⚙️
Node.js Mastery: Design, implement, and maintain highly scalable, secure, and resilient back-end services using Node.js and frameworks like Express.js or NestJS.
API Development: Lead the development and evolution of secure, high-performance RESTful APIs (and/or GraphQL) that power all web and mobile clients.
System Architecture: Contribute to architectural decisions for our microservices, focusing on high availability, disaster recovery, and latency optimization.
Security & Compliance: Implement and rigorously enforce robust authentication (e.g., JWT, OAuth ), authorization, data encryption, and security protocols vital for a cybersecurity product.
Database & Data Management Data Modeling: Expertly design, manage, and optimize complex database schemas using PostgreSQL (preferred) and NoSQL databases like MongoDB .
Performance: Implement advanced caching solutions ( Redis ) and tune database queries to handle large volumes of traffic with speed.
Front-End Integration & Collaboration Integration Point: Work closely with the front-end team (who use React.js and Next.js ) to define API contracts, troubleshoot integration issues, and ensure efficient data fetching patterns.
Next.js Support: Understand how the Next.js framework utilizes the back-end (e.g., API routes, server-side data fetching) to build optimal server responses.
Testing & CI/CD: Write extensive unit and integration tests for all back-end services.

Participate in maintaining and improving the CI/CD pipeline and Docker/Kubernetes deployments.
Non-Negotiable Requirements Experience: 4+ years of dedicated professional experience in server-side/back-end development.
Core Language: Expert proficiency in JavaScript (ES6+) and the Node.js runtime environment.
Database Expertise: Proven experience with both relational ( PostgreSQL or MySQL) and NoSQL ( MongoDB ) databases, including complex query optimization.
API Design: Demonstrated ability to architect and implement secure, scalable RESTful APIs from scratch.
Front-End Awareness: Strong practical understanding of React.js principles and experience working on an application utilizing the Next.js framework.
Highly Desired Expertise (A Strong Advantage) Experience with TypeScript for large-scale back-end applications.
Hands-on experience with Docker and cloud platforms ( AWS, Azure, or GCP ).
Experience in a highly secure Cybersecurity or regulated SaaS environment.
Familiarity with message queuing systems (e.g., Kafka, RabbitMQ).
If you are a talented back-end engineer who is ready to build the core services that power a high-growth platform and thrive in a Node.js/React ecosystem, we encourage you to apply.
