Job Summary:

We are looking for a Full Stack Developer (MERN) with hands-on experience in building highly scalable, performance-driven applications. The ideal candidate should have a deep understanding of both front-end and back-end development, microservices, and database optimization for large-scale systems. You will be responsible for designing, developing, and maintaining applications that can handle high concurrency (1,000+ active users) while ensuring performance, reliability, and scalability.

This role involves working closely with cross-functional teams — including product managers, designers, and DevOps engineers — to deliver cutting-edge, enterprise-grade solutions.

Roles & Responsibilities:

• Design and develop scalable and distributed web applications using the MERN stack (MongoDB, Express.js, React/Next.js, Node.js).
• Build and optimize RESTful APIs for high-performance, concurrent environments.
• Architect and manage MongoDB databases, ensuring high availability, efficient query performance, and scalability.
• Implement queueing systems (e.g., BullMQ, RabbitMQ, Kafka, or Redis Queues) for background jobs and asynchronous processing.
• Optimize server and client performance to support real-time data updates and high concurrent user loads.
• Collaborate with DevOps to improve deployment pipelines, containerization (Docker), and cloud scalability.
• Conduct thorough testing, profiling, and debugging to identify performance bottlenecks and optimize both code and infrastructure.
• Participate in code reviews, architecture discussions, and sprint planning to ensure technical excellence and scalability across all layers.

Qualification / Requirements:

• Bachelor’s degree in Computer Science, Engineering, or related field (or equivalent experience).
• 1 + years of hands-on experience in full-stack development using the MERN stack.
• Proven experience working on applications supporting 1,000+ concurrent users or large-scale distributed systems.
• Strong expertise in:
• Node.js (asynchronous programming, clustering, performance optimization)
• Next.js & React.js (SSR, CSR, and dynamic rendering)
• MongoDB (aggregation pipelines, indexing, schema design for scalability)
• Practical experience with message queues (BullMQ, RabbitMQ, Kafka, or Redis Streams).
• Familiarity with caching mechanisms (Redis, Memcached) to optimize performance.
• Experience with Docker and microservices-based architectures is a plus.
• Good understanding of API design, authentication mechanisms (JWT, OAuth), and security best practices.
• Experience working in Agile environments and using Git-based version control.

Nice to Have:

• Exposure to serverless computing (AWS Lambda).
• Experience with monitoring tools (New Relic, Datadog, ELK Stack).
• Knowledge of CI/CD pipelines and automated deployment workflows.
• Experience in real-time communication (WebSockets, Socket.io).

Why This Role Matters

We’re looking for a Principal Engineer to lead the architecture and execution of our GenAI-powered, self-serve marketing platforms. You will work directly with the CEO to shape, build, and scale products that change how marketers interact with data and AI. This is intrapreneurship in action — not a sandbox innovation lab, but a real-world product with traction, velocity, and high stakes.

What You'll Do

• Co-own product architecture and direction alongside the CEO.
• Build GenAI-native, full-stack platforms from MVP to scale — powered by LLMs, agents, and predictive AI.
• Own the full stack: React (frontend), Node.js/Python (backend), GCP (infra), BigQuery (data), and vector databases (AI).
• Lead a lean, high-caliber team with a hands-on, unblock-and-coach mindset.
• Drive rapid iteration with rigor, balancing short-term delivery with long-term resilience.
• Ensure scalability, observability, and fault tolerance in multi-tenant, cloud-native environments.
• Bridge business and tech — aligning execution with evolving user and market insights.

What You Bring

• 8–12 years of experience building and scaling full-stack, data-heavy or AI-driven products.
• Fluency in React, Node.js, and Google Cloud (Functions, BigQuery, Cloud SQL, Airflow, etc.).
• Hands-on experience with GenAI tools (LangChain, OpenAI APIs, LlamaIndex) is a bonus.
• Track record of shipping products from ambiguity to impact.
• Strong product mindset — your goal is user value, not just elegant code.
• Architectural leadership with ownership of engineering rigor and scaling best practices.
• Startup or founder DNA — you’ve built things from scratch and know how to move fast without breaking things.

Who You Are

• A former founder, senior IC, or tech lead who’s done zero-to-one and 1-to-n scaling.
• Hungry for ownership and velocity — frustrated by bureaucracy or stagnation.
• You code because you care about solving real problems for real users.
• You’re pragmatic, hands-on, and grounded in first principles.
• You understand that great software isn't just shipped — it's hardened, maintained, and evolves with minimal manual effort.
• You’re open to evolving into a founding engineer role with influence over the tech vision and culture.

What You Get

• Equity in a high-growth product-led startup.
• A chance to build global products out of India with full-stack and GenAI innovation.
• Access to high-context decision-making and direct collaboration with the CEO.
• A tight, ego-free team and a culture that values clarity, ownership, learning, and candor.

Why YOptima?

YOptima is redefining how leading marketers unlock growth through full-funnel, AI-powered media solutions. As part of our growth journey, this is your opportunity to own the growth charter for leading brands and agencies globally and shape the narrative of a next-generation marketing platform.
