Backend Software Engineer (Node.js / Full-Stack)

Vision71 Technologies, based in Karachi, is seeking a dependable Backend Software Engineer with strong Node.js expertise and full-stack capabilities. The role focuses primarily on backend development, with occasional contributions to React/Next.js interfaces. You will collaborate closely with the technical lead and a small team to develop, test, document, and deliver software solutions for both client and internal projects. This is a full-time, on-site position requiring clear communication and ownership throughout the development lifecycle.

Key Responsibilities
- Develop and maintain Node.js applications, REST APIs, and integrations using JavaScript/TypeScript with frameworks such as Express or NestJS.
- Design efficient data models and queries using SQL and/or MongoDB tailored to project requirements.
- Implement authentication, authorization, validation, error handling, and secure management of credentials and business data.
- Identify, reproduce, and fix bugs by investigating logs, addressing root causes, and adding automated tests.
- Improve existing codebases, manage Git branches and pull requests, and actively participate in code reviews.
- Contribute to frontend development using React/Next.js and integrate these interfaces with backend services.
- Support staging environments, manage approved deployments, troubleshoot production issues, and plan rollbacks with clear handovers.
- Break down requirements into manageable tasks, provide realistic estimates, and proactively communicate blockers or delivery risks.
- Maintain comprehensive API documentation, setup guides, task updates, and handover notes.
- Evaluate and prototype new tools when justified by project needs.

Required Qualifications
- Approximately 2–4 years of hands-on software development experience; strong candidates outside this range will also be considered.
- Proficient in Node.js and JavaScript/TypeScript, including asynchronous programming, API design, and debugging.
- Experience delivering or maintaining applications used by real users, with the ability to clearly articulate your personal contributions.
- Working knowledge of database design, query optimization, indexing, and migrations relevant to your technology stack.
- Familiarity with React or Next.js, Git version control, API testing, and automated testing practices.
- Sound judgment regarding maintainability, security, and technical trade-offs.
- Ability to work full-time on-site in Karachi with clear and effective communication skills.
- Relevant academic degree or equivalent practical experience.

Preferred Qualifications and Benefits
Experience with Docker, Linux, CI/CD pipelines, cloud hosting, background job processing, queues, third-party API integrations, reporting dashboards, and business software integrations is advantageous.

Candidates are expected to demonstrate integrity, reliability, and ownership by providing accurate progress updates, promptly reporting issues or delays with proposed solutions, adhering to review and deployment protocols, respecting confidentiality and intellectual property, and responsibly using AI tools. Maintaining agreed working hours, communicating availability changes promptly, and ensuring thorough handovers are essential.

Success in this role involves quickly understanding an existing codebase, delivering well-tested and documented features, communicating progress proactively, and gradually taking full ownership of backend tasks from clarification through to handover.

Applicants should submit an accurate CV via LinkedIn, including portfolio or repository links that clearly identify their personal work. Confidential code or credentials from previous employers must not be shared.
