Job description

Bangalore North, India | Posted on 03/24/2026

We are looking for a skilled MERN Stack Developer to join our engineering team. You will be responsible for building and maintaining scalable web applications, working across both frontend and backend, and contributing to the evolution of our platform architecture. The ideal candidate is someone who takes ownership, thinks in systems, and is comfortable operating in a fast-paced environment.

Key Responsibilities

• Design, develop, and maintain web applications using the MERN stack (MongoDB, Express.js, React.js, Node.js)
• Build responsive, accessible, and performant frontend interfaces using React with Tailwind CSS and shadcn/ui or similar framework.
• Develop and maintain RESTful and/or GraphQL APIs on Node.js
• Work with microservices architecture — designing, deploying, and maintaining independently deployable services
• Integrate and work with event-driven pipelines using tools such as Apache Kafka, RabbitMQ, or similar messaging/streaming platforms
• Collaborate with product, design, and QA teams to translate requirements into technical solutions
• Write clean, testable, well-documented code and participate actively in code reviews
• Troubleshoot production issues, optimize application performance, and contribute to CI/CD pipelines
• Participate in architectural discussions and contribute to technical decision-making

Must-Have Skills

• Strong proficiency in React.js with hands-on experience using Tailwind CSS and shadcn/ui component library
• Solid backend experience with Node.js and Express.js
• Working knowledge of MongoDB (schema design, aggregation pipelines, indexing)
• Practical experience building or working within a microservices architecture
• Hands-on exposure to event streaming / message queue systems such as Apache Kafka, RabbitMQ, AWS SQS/SNS, or similar tools
• Familiarity with version control (Git), CI/CD practices, and containerization basics (Docker)
• Strong understanding of RESTful API design, authentication/authorization patterns (JWT, OAuth), and application security fundamentals
• Ability to write unit and integration tests

Good to Have

• Experience with React Native for mobile application development
• Exposure to cloud platforms (AWS, Azure, or GCP)
• Experience with TypeScript across frontend and backend
• Familiarity with infrastructure tooling — Kubernetes, Terraform, or similar
• Experience with monitoring and observability tools (Sentry, Datadog, Grafana)
• Understanding of database scaling strategies (replication, sharding, caching with Redis)

What We Value

• Ownership mindset — you don't wait to be told what to do
• Clear communication and the ability to articulate trade-offs in technical decisions
• A bias toward simplicity and pragmatism over over-engineering
• Curiosity to learn new tools and adapt to evolving requirements
