Backend & Full Stack Developer — React.js

We’re Hiring: Backend & Full Stack Developer — React.js, AWS & AI Products
Company: Cyurae
Experience: 3–5 years
Location: Gurugram — Onsite
Employment: Full-time
Cyurae is building an AI-powered consumer product at the intersection of fashion and technology. We are looking for a hands-on Backend & Full Stack Developer who can build, test, deploy and maintain scalable applications.
You should have strong React.js and backend development experience, practical exposure to AI-based products, and hands-on experience deploying applications on AWS. You will work with the CTO, AI engineers, mobile developers, designers and QA to take features from requirements through production delivery.
Key Responsibilities
Backend development: Design and build secure REST APIs, business logic and application services. Implement authentication, authorization, input validation, error handling and clear API documentation.
React.js development: Build responsive interfaces and reusable components using React.js and JavaScript/TypeScript. Integrate APIs, manage application state and implement reliable loading, error and form-validation behaviour.
Scalable application development: Design applications for growing traffic and concurrent users. Apply database indexing, query optimization, caching, connection pooling and background processing. Identify bottlenecks through profiling and load testing.
AWS deployment and operations: Deploy and operate applications on AWS using Docker and CI/CD pipelines. Manage staging and production environments, configuration, secrets, monitoring, health checks, backups and release rollback. Troubleshoot deployment failures and production issues.
AI product integration: Integrate AI APIs and internal model services into application workflows. Handle asynchronous jobs, progress updates, retries, timeouts and provider failures. Validate responses and monitor latency and usage costs.
Database and security: Design and maintain PostgreSQL schemas, migrations and transactions. Use Redis appropriately for caching and rate limiting. Protect credentials and user data, enforce server-side access controls and implement secure file handling.
Testing and quality: Write unit, integration and end-to-end tests. Work with QA on regression, API, performance and failure-case testing. Review code, resolve defects and integrate automated checks into the delivery pipeline.
Delivery and ownership: Break requirements into tasks, estimate effort and communicate blockers early. Deliver against agreed acceptance criteria, document changes and coordinate releases using GitLab and Jira. Own features through deployment and post-release support.
Required Skills and Experience
3–5 years of professional backend, full stack or product engineering experience, including hands-on work on AI-enabled applications.
Strong React.js, JavaScript/TypeScript, HTML and CSS skills.
Production experience with a server-side framework, REST APIs, authentication, authorization and third-party integrations.
Hands-on AWS application deployment experience is mandatory. You should be able to explain the services you used, how releases were deployed and how production issues were resolved.
Practical experience with Docker, Git, Linux and CI/CD, including configuration, secrets, monitoring and rollback.
Strong SQL and PostgreSQL skills, with experience in caching, background jobs and asynchronous processing.
Experience building scalable products or improving application performance, supported by examples of bottlenecks identified and measurable improvements.
Experience writing automated tests, debugging frontend and backend issues, and delivering features through staging to production.
Ability to take ownership of implementation, testing and delivery while collaborating effectively with other engineers.
Willingness to work onsite in Gurugram. Candidates outside Gurugram must be willing to relocate.
Good to Have
Experience with AWS EC2 or ECS, RDS, S3, IAM and CloudWatch.
Infrastructure as code, WebSockets and production observability tools.
Exposure to embeddings, vector search, media-processing workflows or integration with Python AI services.
Experience working in a startup and collaborating with AI, mobile and QA teams.
What We Want to See
Be ready to explain an application you personally built and deployed, your contribution to an AI-enabled feature, the AWS deployment setup, a scalability challenge you solved, and how you tested and delivered the release.
