About Kaari

Kaari Labs is building spatial commerce infrastructure for modern retail. We help brands turn product images into interactive 3D and AR shopping experiences, and an end to end solution that allows customers to build and deploy 3D assets on the web.

Our Vision

Our larger vision is to build 3D intelligence that enables AI to understand the physical world. This involves building foundational 3D AI models and workflows that can create and edit 3D assets and scenes in filmmaking, robotics, and manufacturing, on problems like virtual set designing, and product prototyping.

These are ambitious goals, and to get there sustainably we have started with e-commerce as a wedge to break into the market. Our current offering turns product pages into interactive 3D experiences, this includes 3D asset generation, an AI-native 3D editor, and delivering mixed reality shopping experiences on the web. Spatial commerce has a clear commercial value and fast feedback loops, making it the right entry point into broader 3D intelligence.

This positions us to balance revenue alongside having a testbed for evaluating and experimenting on moonshot 3D AI problems.

Role Description

We're hiring a software lead who lives in the code. You will own large parts of Kaari's product: the AI-native 3D editor, dashboards, APIs, and set the technical defaults for how we ship. You should be comfortable making architectural calls and reviewing work. This is for someone who has already led development on a production system and wants to do that again in a small, fast-moving team. This is a full-time hybrid role based in Mumbai, with flexibility for partial work from home.

What you will work on





- Own end-to-end product slices: React/TypeScript UI, Next.js flows, APIs, storage, auth, embeds
- React and TypeScript frontend experiences for dashboards, editors, viewers, and configurators
- Next.js product flows for 3D asset management, material libraries, analytics, and client-facing tools
- Backend APIs, storage flows, signed asset delivery, authentication, and integrations
- Scalable systems for serving 3D/AR experiences through lightweight embeds on brand websites
- Internal tools that help teams generate, refine, manage, and deploy 3D product assets faster
- Product decisions around performance, UX, reliability, and developer experience along with deciding the quality and the architecture bar

What we are looking for

- 3-5 years of professional software engineering experience
- Strong React, TypeScript, and modern frontend fundamentals
- Experience building full-stack production grade products, preferably with Next.js or similar frameworks. We don't care too much about AI slop demos.
- Solid software design and database fundamentals — you can make sound architectural calls across APIs, schema design, caching, auth, and deployment.
- Experience making high-level technical decisions and setting the engineering standard in a fast-paced startup environment.




- Strong product mindset: you bridge the gap between engineering and user needs, ensuring technical decisions drive real business value.
- Thoughtful use of AI: Everyone uses it, but we need you to understand every code change you make so that you are in control of your AI and not the other way round.
- Bachelor's or Master's in CS/Engineering, or equivalent practical experience.

Bonus Points

- Background or interest in 3D, graphics, AR/VR, or applied AI is a strong plus.
- Experience technically leading a small team or owning a product area.
- Experience with cloud infrastructure and deployment.

The Kind of Person Who'll Fit

We want builders who take ownership, communicate clearly, and are not afraid to take on hard problems even when that requires learning new skills. Disagreement is expected. Power games are not. Argue hard, stay decent, then commit to what is best for Kaari.

We value unusual technical or creative interests, and solid fundamentals. If you are excited about difficult problems in 3D, AI, and product engineering, and want to turn imagination into something real, you will fit well.

Why Join Kaari

You'll set technical direction on a product at the intersection of commerce, 3D, and advancing AI, while staying in the code. Small team, close to product and customers, real say in how the company gets built.

To Apply

Send your resume, GitHub/portfolio if available, and a short note about a production system you owned or are proud of: what you decided, what you shipped, and any opinions you have of Kaari.
