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.
