Full Stack Software Engineer

Kalakar.io is an innovative AI-powered captioning platform focused on Desi languages such as Urdu, Hindi, and other regional dialects. Our mission is to help creators effortlessly generate accurate captions and subtitles, making their video content more accessible, engaging, and shareable. Currently, over 100,000 creators and businesses rely on Kalakar.io to enhance their digital presence across various social platforms.

Key Responsibilities
You will be responsible for building and delivering new features across our React frontend and Node.js/Express backend. This includes designing and optimizing PostgreSQL schemas, writing efficient queries, and tuning database performance. You will integrate AI-driven captioning pipelines to create seamless and intuitive user experiences. Improving our caption editor and video rendering workflows will be a core part of your role. Additionally, you will work on scaling systems capable of processing thousands of videos efficiently. You will take full ownership of your projects, managing them end-to-end from concept through production.

Required Qualifications
Candidates should have at least 3 years of professional experience working with React and Node.js. Strong proficiency in PostgreSQL, including schema design and query optimization, is essential. Experience in designing and building RESTful APIs using Express is required. We are looking for someone who thinks beyond individual tasks and genuinely cares about delivering a great user experience. The ideal candidate should be comfortable working independently in a fully remote, asynchronous environment. A passion for problem-solving and shipping complete products, rather than just writing code, is important. Experience with AWS services such as EC2, S3, or Lambda for deploying and managing applications is also necessary.

Preferred Qualifications and Benefits
Experience with Remotion (React-based video rendering), audio/video processing, or AI and large language model (LLM) API integrations will be considered a strong advantage. Familiarity with speech-to-text technologies or machine learning applications is a plus. Knowledge of South Asian languages or an understanding of the Desi creator ecosystem will help you connect more deeply with our user base.

We operate as a fully remote team with flexible working hours, allowing you to balance your work and personal life effectively. Our small, agile team values minimal bureaucracy, fast feedback cycles, and quick product releases. We emphasize extreme ownership and provide a high degree of autonomy, empowering you to make meaningful contributions.

Role Details
This is a full-time software engineering position based remotely. The monthly salary offered is PKR 300,000.

We encourage applicants to share a brief, original introduction about themselves instead of submitting a generic or AI-generated cover letter. Please tell us who you are, what motivates you about software engineering, and what kinds of products or problems you have enjoyed working on. We value authenticity and originality over polished writing.

If you are passionate about building tools that serve an underserved community and want your work to impact tens of thousands of real users, we would love to hear from you.
