Join a small, highly collaborative on-site team in Gurugram where you will contribute end-to-end to product development, use cutting-edge frontend and backend technologies, leverage AI-assisted coding tools to accelerate delivery, and influence product strategy in a fast-paced, non-9-to-5, face-to-face working culture.

Key Responsibilities

• Develop and ship high-quality frontend applications using Vite, ReactJS and NextJS; implement responsive, accessible UIs and reusable design-system components that align with product and UX goals.
• Design and implement backend services in Node.js and Python (Express/Fastify, Flask/FastAPI), building scalable, maintainable APIs and microservices that integrate with PostgreSQL, MySQL and MongoDB.
• Use AI-assisted coding tools (e.g., Cursor, Windsurf, Lovable.dev, AntiGravity or similar) to accelerate implementation, generate prototypes, automate repetitive tasks and create tests and documentation while maintaining strong engineering standards.
• Own features end-to-end: contribute to architecture and technical design, implement code, write tests, deploy to CI/CD pipelines, instrument observability, and iterate based on user feedback and analytics.
• Collaborate closely with product managers, UX/UI designers, QA and security stakeholders to translate requirements into technical deliverables, estimates and release plans; participate actively in roadmap and prioritization discussions.
• Participate in rigorous code reviews, promote best practices for testing and security-first development, and help maintain an efficient, reliable development workflow to enable rapid iterations.
• Write clear prompts for AI tools and produce high-quality documentation, README files and code comments to ensure team knowledge transfer and maintainability.

Required Qualifications

• 2–4 years of professional software development experience, preferably with product or agency teams delivering web applications.
• Proven experience building frontend applications with Vite, ReactJS and NextJS, including SSR/ISR patterns, routing, state management and performance optimization.
• Strong backend development skills in Node.js and Python using modern frameworks (Express, Fastify, Flask, FastAPI) and experience designing RESTful APIs and services.
• Solid practical experience with relational and document databases (PostgreSQL, MySQL, MongoDB): schema design, queries, indexing and migrations.
• Demonstrable experience using AI coding assistants to accelerate development, refactor code, generate tests or documentation, and improve code quality.
• Good software engineering fundamentals: data structures, algorithms, system design basics, debugging and writing maintainable, testable code.
• Familiarity with Git, code review workflows and CI/CD; GraphQL knowledge is a plus.
• Strong written and verbal communication skills, clear prompt-writing ability, and ability to explain technical trade-offs to non-technical stakeholders.
• Ability to work on-site in Gurugram, Haryana, India; flexibility to work beyond strict 9–5 hours when project needs demand.
• Bachelor’s degree in Computer Science, Engineering or equivalent practical experience.

Preferred Qualifications

• Experience with TypeScript, GraphQL, WebSockets or other real-time systems.
• Familiarity with cloud platforms (AWS, GCP or Azure), containerization with Docker and building CI/CD pipelines.
• Experience with testing frameworks and automated test strategies (Jest, Cypress, PyTest) and a focus on test coverage and reliability.
• Knowledge of performance optimization, front-end security best practices and accessibility (a11y) standards.
• Prior exposure to product management or demonstrated product sense: defining MVPs, prioritization and customer-driven iteration.
• Contributions to open-source projects, personal projects or a portfolio of shipped products demonstrating craftsmanship.
• Experience in agency-style or client-facing roles where speed, communication and adaptability are essential.

What We Offer

• Work Location: On-site in Gurugram, Haryana, India with a collaborative, face-to-face team culture.
• Competitive salary commensurate with experience and performance-based bonuses.
• Meaningful ownership of product features and direct influence on product direction and roadmap.
