This role is ideal for someone who has worked in a high-growth B2B SaaS environment, thrives in fast-moving teams, and enjoys owning products from concept to production. While this is a frontend-heavy role, backend experience is a strong advantage.

We're especially interested in candidates from Tier 1 engineering institutes (IITs, BITS, IIITs, NITs) or those who have built products at Y Combinator-backed startups.

What You'll Be Doing

• Build high-performance, scalable web applications using React, Next.js, TypeScript, and modern frontend technologies.
• Develop intuitive, responsive, and pixel-perfect user experiences.
• Work closely with product, design, and engineering teams to deliver features end-to-end.
• Optimize applications for speed, scalability, and reliability.
• Debug complex issues and maintain high code quality through testing and engineering best practices.
• Contribute to architecture discussions and continuously improve engineering standards.
• Work across the stack when needed. Experience with Python and backend development is a plus.

What We're Looking For

• At least 2 years of professional software engineering experience.
• Experience building products in a B2B SaaS company.
• Strong preference for candidates from Tier 1 engineering colleges (IITs, BITS, IIITs, NITs) or engineers with experience at Y Combinator-backed startups.
• Strong expertise in JavaScript, TypeScript, React, and Next.js.
• Excellent understanding of HTML5, CSS3, responsive design, and frontend performance optimization.
• Experience integrating REST APIs and working with modern frontend architectures.
• Backend experience with Python is a strong plus but not mandatory.
• Strong problem-solving skills, attention to detail, and a product ownership mindset.
• Excellent communication and collaboration skills.

Why You'll Love Working With Us

• Competitive salary with performance-based growth opportunities.
• Potential to earn up to 1.5x your monthly salary through overtime. We believe in rewarding commitment and exceptional execution.
• Work alongside some of the best engineering talent and accelerate your learning.
• Ship meaningful features at high velocity with real ownership from day one.
• Flexible working hours and a remote-first culture.
• High-impact role with significant autonomy and the opportunity to shape products used by millions.

We're a small, ambitious team that values talent, execution, and ownership. If you enjoy solving hard problems, moving quickly, and building products that matter, we'd love to hear from you.
