Job description

About the Role:

We’re looking for an experienced Senior Full Stack Developer (MEAN/MERN) to support the development of scalable, secure web applications for a global health-tech platform. In this position, you’ll work across the full stack — from front-end interfaces to backend services — contributing to feature development, architecture planning, and team mentorship.


Key Responsibilities:

  • Develop and maintain scalable front-end and back-end components using Node.js, React, MongoDB, and related technologies.

  • Collaborate with UI/UX designers, QA engineers, and DevOps specialists to deliver reliable, user-focused features.

  • Design and implement RESTful APIs and integrate them with cloud-based infrastructure.

  • Ensure code security and quality by adhering to OWASP best practices and relevant compliance standards such as HIPAA and GDPR.

  • Conduct unit testing, code reviews, and contribute to continuous integration processes.

  • Mentor and support junior developers, while actively participating in architectural and technical decision-making.


Qualifications:

  • At least 5 years of hands-on experience working with the MERN or MEAN stack.

  • Strong expertise in MongoDB, Express, React, and Node.js.

  • Practical experience with cloud services (preferably AWS).

  • Familiarity with WebSockets, RESTful APIs, CI/CD pipelines, and Agile development practices.

  • Experience working with databases such as MongoDB, PostgreSQL, or similar systems.

  • Solid understanding of security best practices (OWASP) and infrastructure automation tools.

  • Excellent English communication skills, both verbal and written.

  • Comfortable working with distributed teams and overlapping hours with colleagues based in Pakistan and the United States.
