Our team is small, elite, and composed of industry veterans, including engineering leadership formerly of Meta.

The Role

We are looking for a scrappy, high-agency Full-Stack Engineer with 2 to 5 years of experience to join our core team. This isn't a role where you’ll be a small cog in a giant machine.

What to Expect (The Reality)

• High Velocity: We move fast. The workload is high, the deadlines are tight, and the quality bar is even higher.
• Extreme Impact: Every line of code you write will directly influence the success of our e-commerce partners.
• Direct Access: Reporting to the CEO means your ideas are heard immediately, and your feedback shapes the product roadmap.

Why Join Us?

• Equity/Growth: As an early member of a small team, you will have significant upside as the company scales.

The Ideal Candidate

You are a "Product Engineer" at heart. You don't just want a ticket assigned to you; you want to understand the "why" behind the feature. You are based in Maharashtra and are ready to put in the hours to build something that defines a category.
