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.

• Web Development: Creating and implementing the technical aspects of websites and web applications

• This involves working with programming languages such as HTML, CSS, and JavaScript to build the front-end (user interface) and back-end (server-side logic)

• Web Design: Collaborating with designers and using design tools to translate mockups and wireframes into functional web pages that align with the visual and user experience (UX) design

• Front-end Development: Focusing on the client-side of the application, ensuring responsive and interactive user interfaces, optimizing for various devices and screen sizes

• Back-end Development: Dealing with the server-side logic and databases to handle data storage, retrieval, and manipulation

• This may involve working with technologies like Node.js, Python, PHP, and more.

• Database Management: Creating and maintaining databases that store website/application data efficiently and securely

• Testing and Debugging: Identifying and fixing technical issues, ensuring the website or application functions smoothly across different browsers and devices

• Website Optimization: Improving website/application performance, load times, and overall user experience

• Version Control: Using version control systems (e g, Git) to manage code and collaborate with other developers

• Security: Implementing security measures to protect websites and applications from potential threats and vulnerabilities

• Collaboration: Working closely with designers, other developers, and stakeholders to ensure project requirements are met and deadlines are followed

• Continuous Learning: Keeping up with the latest web technologies, trends, and best practices to improve skills and stay current in the rapidly evolving web development landscape

• Deployment and Maintenance: Deploying websites/applications to servers and performing regular updates and maintenance to keep them running smoothly

• Troubleshooting: Investigating and resolving technical issues that arise from user feedback or testing

•

•

Desired Candidate Profile

• Engineering graduate (BE/B.Tech) or BCA/MCA from a reputed university.

• Ability to develop and manage e-commerce websites and web applications.

• Good understanding of fundamentals and concepts of PHP Scripting language.

• Good understanding of Smarty language.

• Hands-on experience in front-end technologies such as JavaScript, HTML5, jQuery and CSS3.

• Knowledge of OOPS & Database.

• Strong written and oral communication skills.

• Attention to detail and excellent organizational skills.

• Alternate Saturday and all Sunday will be fixed off
