Sr. Full Stack Node.Js Developer Remote Jobs Karachi Freelance

Younes Biane, an independent software company from Stuttgart, is hiring a Senior Full Stack Node.js Developer for a fully remote contract engagement, open specifically to candidates based in Pakistan. This role sits behind the scenes of AI-powered SaaS products built for text, photo, and video processing, working on backend services, worker infrastructure, and a lightweight frontend layer.

Why This Job Matters

There’s a real difference between a developer who can write an API endpoint and one who actually understands how a production system behaves under load, at 3 AM, when a background job queue backs up or a webhook from a payment provider fails silently. This role is built for the second kind of developer.

The company is small and independent, building AI-powered products that process real files at real scale, meaning the backend work here isn’t decorative, it’s the actual engine room. For a Pakistan-based developer who wants genuine remote international work, paid in a currency-adjusted range, and who already has real Node.js production experience rather than tutorial-level familiarity, this is a solid opportunity to work directly with a small European team rather than through several layers of outsourcing middlemen.

About Younes Biane

Younes Biane is an independent software company based in Stuttgart, Germany, building AI-powered SaaS products focused on text and video processing. Their technology stack centers on a Node.js and Express backend, PostgreSQL with migration-based schema management, Redis, background job queues and workers, and REST APIs. As a smaller, independent company rather than a large enterprise, the team here likely works close to the actual product, giving a remote hire meaningful influence over real architectural decisions rather than being one small cog in a massive engineering org.

Vacancies Overview

One Senior Full Stack Node.js Developer position is open, structured as a temporary remote contract on a rotation shift schedule. This is a single, focused hire rather than a team build-out, which suggests the company needs someone who can operate independently and take real ownership of backend services from day one.

Eligibility Criteria

Key Responsibilities

• Design, implement, and maintain Node.js and Express backend services and REST APIs, including routing, error handling, and performance optimization
• Develop and maintain PostgreSQL schema changes and migrations, writing efficient queries and tuning indexes
• Implement and support background job queues and worker infrastructure using tools like Bull or Bee-Queue
• Use Redis for caching, pub/sub messaging, and rate limiting
• Integrate webhooks and third-party APIs, including payment providers and provider routing systems
• Implement automated testing including unit and integration tests, following TDD and CI/CD practices
• Maintain observability through logging and error monitoring for production services
• Work in GitHub using PR workflows and branch protection, collaborating with AI-assisted tooling as needed
• Implement lightweight frontend components using Vanilla JS and Alpine.js

Required Qualifications

Candidates need at least 4 years of professional backend web development experience with demonstrable Node.js projects that have actually been deployed to production, not just built as personal projects. Deep familiarity with Express, REST API design, and PostgreSQL schema design and query optimization is essential, alongside genuine hands-on experience with background job queues, Redis for caching and pub/sub, and integrating third-party payment APIs.

Strong testing discipline matters here too, since automated unit and integration testing under TDD and CI/CD practices is explicitly listed as a must-have, not a nice-to-have. Good written and verbal English is required given the remote, international nature of this role, and familiarity with vector databases like pgvector or RAG techniques is considered a bonus for candidates who have that exposure.

Application Process

Candidates apply directly through the official Mustakbil.com listing for this position. Given the technical depth expected, applicants should be ready to point to specific production Node.js projects they have built and deployed, rather than describing experience in general terms. Applications remain open until 30 September 2026, 10:00 PM UTC.

Required Documents

• Updated CV clearly detailing backend Node.js development experience and production deployments
• Links to GitHub repositories or a portfolio showcasing relevant projects, if available
• Educational certificates confirming the Bachelor’s degree requirement
• Any documentation of experience with background job queues, Redis, or payment API integrations

Test Pattern and Selection Process

The official listing does not describe a formal written test, though a technical assessment or take-home coding task is common practice for backend roles of this depth. Selection is likely based on CV and portfolio review followed by a technical interview covering Node.js architecture decisions, database schema design, and how the candidate has handled production issues like queue backlogs or failed webhook deliveries in the past.

Preparation Tips

• Prepare specific examples of production Node.js systems you have built, including how you handled scaling issues or background job failures.
• Refresh your understanding of PostgreSQL migrations and query optimization, since this is named as a core, hands-on requirement, not background knowledge.
• Be ready to explain how you have used Redis for caching, pub/sub, or rate limiting in a real project.
• Brush up on TDD and CI/CD workflows if it has been a while, since automated testing discipline is explicitly required.
• If you have any exposure to vector databases like pgvector or RAG techniques, mention it clearly, since it is listed as a valuable bonus skill.

Salary Details

Younes Biane has advertised a clear monthly salary range of PKR 93,600 to 100,000 for this role. For a remote contract position with a European employer, this range reflects a fairly typical rate for a mid-senior backend developer working from Pakistan, and candidates with stronger production experience or additional skills like RAG or vector database familiarity may have room to negotiate toward the top of the stated range.

Benefits

• Fully remote work with an international, Europe-based employer.
• Direct exposure to real AI-powered SaaS products in text, photo, and video processing.
• Meaningful ownership over backend architecture decisions given the company’s smaller, independent structure.
• Opportunity to work with modern tooling including CI/CD, automated testing, and AI-assisted development tools.
