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.
