Job description
 
                         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.
