Fullstack Engineer

Location: Maharashtra, India (Remote / Hybrid) Company: Videoselz Reporting to: CEO

About Videoselz

Videoselz is a fast-paced, Silicon Valley-based startup on a mission to revolutionize how e-commerce brands grow. We build high-performance video processing tools that empower brands to turn content into revenue. 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. You will report directly to the CEO, working alongside leaders who have scaled products for billions of users. You will be expected to wear multiple hats, moving seamlessly between architecting backend services and crafting fluid frontend experiences.

Technical Requirements

• Experience: 2–3 years of professional software development experience.
• The Stack: Deep proficiency in JavaScript, React, and Svelte.
• Full-Stack Mindset: Strong foundational knowledge of backend architecture and the ability to own a feature from database schema to UI deployment.
• Versatility: You are comfortable jumping into unfamiliar territory, whether it's optimizing video rendering pipelines or refining a checkout flow.

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?

While we work hard, we believe in taking care of our "A-Players." We offer a Silicon Valley-style environment right here in Maharashtra.

• Mentorship: Learn directly from ex-Meta engineering leaders who understand how to build world-class systems.
• Generous Benefits: Competitive salary.
• Rest & Recharge: We offer "Days Off" policy. We believe that when you aren't working, you should be completely disconnected so you can come back at 100%.
• 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.
