Job Overview
- This listing is for a Full Stack Engineer position. The role is remote and is classified as full-time. For salary, the listing states rs,. The requirements point towards JavaScript, TypeScript, React.js, PostgreSQL, AWS and Artificial Intelligence. The listing is aimed at the following profile: 4+ years. For general context: React is a popular library for building interactive user interfaces. Artificial intelligence is increasingly part of everyday software products. Interested candidates can review the full details below and apply using the link provided on this page.
What These Requirements Mean in Practice
- ★ JavaScript: Typically means writing and debugging everyday JavaScript, including asynchronous code, array and object handling, and modern ES6+ syntax.
- ★ TypeScript: Adds types to JavaScript so mistakes are caught earlier; day to day it means defining interfaces and typing function inputs and outputs.
- ★ React.js: Building user interfaces from reusable components and managing the data that changes on screen.
- ★ PostgreSQL: A relational database where data lives in related tables; the work usually involves writing SQL and designing schemas.
- ★ AWS: Using cloud platform services for hosting, storage and databases instead of managing physical servers.
- ★ Flutter / React Native: Building mobile apps for Android and iOS from a single codebase.
- ★ Artificial Intelligence: A general understanding of how AI systems learn from data, where they are useful, and where they can be unreliable.
Skills to Brush Up Before Applying
- ★ JavaScript: promises and async/await, array methods such as map, filter and reduce, closures and scope
- ★ TypeScript: interfaces versus type aliases, generics basics, typing API responses
- ★ React.js: components, props and state, useState and useEffect, lists, forms and conditional rendering
- ★ PostgreSQL: joins, indexes, transactions and constraints
- ★ AWS: core compute and storage services, permissions and access control, basic deployment
- ★ Flutter / React Native: widgets or components, state management, calling APIs
- ★ Artificial Intelligence: supervised versus unsupervised learning, common real-world use cases, limitations and bias
Who May Be a Good Fit for This Role?
- This role may be suitable for candidates who match the skills and experience described in the requirements. Applicants with working knowledge of JavaScript, TypeScript, React.js, PostgreSQL, AWS and Artificial Intelligence may feel well prepared for what the listing describes. A remote arrangement may suit people who work well independently and communicate clearly in writing. This is editorial guidance only, and the employer makes the final decision on suitability.
Application Tips
- Applicants may want to highlight relevant experience with JavaScript, TypeScript, React.js and PostgreSQL in their CV. If you have used AI tools or built small projects with language models, briefly describe what you built and how you checked the results. Keep your CV to the point and tailor the summary to this role rather than sending a generic version. These are general tips, not requirements stated by the employer.
