Fullstack Developer

What role will you play? 

As a Full Stack Engineer, you will play a pivotal role in our development team, bridging the gap between the visual elements and the server-side infrastructure. You will be instrumental in developing full-fledged, scalable applications by combining the art of design with the science of programming. With your expertise in both front-end and back-end technologies, you will ensure the entire stack is designed and built for speed and functionality.  

Your day to day will involve designing and developing dynamic, high-quality web applications, leveraging the Node.js and python for the back end services and React/Angular for the front end. Close collaboration with UI/UX designers will be essential, allowing you to bring web designs to life while ensuring high performance and responsiveness. Additionally, you will actively participate in coding, debugging, and testing to deliver reliable solutions whilst also working closely with other developers, designers, and product managers, fostering a collaborative environment to meet project goals and deadlines effectively. 

What you offer 

• Proficiency in Typescript and a good understanding of React  
• Solid experience with the Node.js, including the ability to develop RESTful APIs 
• Experience with containerisation of service using Docker 
• Knowledge of modern authorisation mechanisms, such as JSON Web Token (JWT)  
• Familiarity with SQL databases, such as PostgreSQL 
• Experience with Kafka or other event driven tools and tech 
• Nice to have some experience integrating with LLMs through open AI, Gemini etc. 
• Nice to have exposure to AI tooling – Claude, Copilot, Cursor etc. 
• AWS experience is a nice to have 

Senior Full Stack Engineer

We’re looking for a Senior Full Stack Engineer who loves to build. This role is all about getting things working—fast—and then making them solid.

You’ll be hands-on across the stack, taking defined user journeys and turning them into real, clickable prototypes, then hardening them into reliable, production-ready features. There’s no people management here—just solving problems, writing code, and shipping.

You’ll work closely with your Innovation partner (who’s experimenting with new ideas and patterns) and help bring those ideas into the product in a practical, shippable way. We collaborate remotely, with in-person sessions to whiteboard, pair, and move things forward quickly.

Our Core Tech Stack

Frontend

• React + TypeScript (Vite)
• Storybook

Backend & APIs

• .NET (Minimal APIs)
• TypeScript (Node.js / Express)
• REST and gRPC

Testing

• Playwright (E2E & API)
• Vitest

AI / Process

• Agentic-driven code generation
• Automated workflow validation and refinement

What You’ll Do

• Build end-to-end features across frontend and backend—from idea to demo to production-ready.
• Turn lightweight wireframes and “good enough” requirements into working software.
• Prototype quickly, then clean things up: edge cases, error handling, performance, tests.
• Take AI-generated code and make it production-worthy.
• Plug experimental UI and workflows into our core applications and services.
• Work closely with design and engineering to keep things practical and moving.

What We’re Looking For

• You’re an experienced full stack engineer who likes shipping more than theorizing.
• You’re comfortable working across React + TypeScript and modern backend APIs.
• You enjoy ambiguity and don’t need everything fully specified to get started.
• You use AI tools to move faster—but you know when to step in and clean things up.
• You care about quality, testing, and building things that don’t fall over later.
• You’re self-directed, motivated, and take ownership of what you build.

What Success Looks Like

• Features go from idea to working demo quickly.
• Prototypes turn into stable, production-ready flows.
• Core admin and platform functionality “just works.”
• New ideas don’t stay experimental—they make it into the product.

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.
