• High Impact & Ownership: Your work will directly enhance the shopping experience of 50M+ shoppers daily. At StarApps, developers deploy code daily and see the immediate impact on thousands of merchants – you’ll own projects end-to-end and build features that matter.
• Fast-Growing, Profitable Startup: Join a bootstrapped, profitable company on an exciting growth trajectory (from $4M to $10M ARR). There’s no bureaucracy here – just a passionate team obsessed with product quality and merchant happiness. You’ll be part of our core team as we scale, with ample opportunities to grow into leadership roles.
• Cutting-Edge Tech & Challenges: Work with modern technologies (React, Rails, AWS) on performance-intensive applications. Tackle complex challenges in scaling, optimization, and UX for a global user base – continuously sharpen your skills in a supportive, learning-focused environment.

Growth & Benefits: We invest in our team’s growth. Expect a competitive salary, performance bonuses, and whatever tools you need to do your best work. We sponsor professional development (courses, conferences, books) and encourage knowledge-sharing. You’ll enjoy a flexible leave policy, team off-sites, and the excitement of building a global product from our new office in Baner, Pune.

Founding Full-Stack Engineer

Consumer AI | Delhi (Hybrid) | Building for the US Market

The Opportunity

We are a pre-seed startup redefining fashion discovery. We believe the future of e-commerce isn't about search bars and endless scrolling; it’s about context-aware curation.

We are looking for a Founding Full-Stack Engineer who sits at the intersection of Systems and Design. You will be the technical anchor of the team, turning chaotic web data into a fluid, consumer-grade experience.

The Role

You won't just be writing code; you will define the product's architecture. We need Vertical Ownership—the ability to take a feature from a raw database row all the way to a pixel-perfect interaction on the screen.

• The Data Engine (Backend & Scraping): You will build robust data pipelines that scrape and frequently refresh data from top fashion retailers. You will further structure and enrich this data, add additional attributes and prepare it for downstream consumption. Added bonus: prior experience with feature engineering
• The Experience (Frontend): You will craft the user interface. We are building a consumer brand, so "functional" isn't enough—it needs to feel "alive.”. If you have a refined design sense, and prior exposure to building eComm websites with complex landing and category pages, then you are the right fit for this role. 
• The Intelligence (AI Integration): You should be able to understand and re-run existing research algorithms on Fill-In-The-Blank (FITB) tasks.

The Toolkit

• Core Stack: Python for the heavy lifting; JavaScript/TypeScript (React) for the web interface.
• Data Ops: Experience building complex scrapers, handling proxies, and managing data pipelines is non-negotiable.
• Design Engineering: A strong grasp of building advanced eCommerce components (multi-tile grid layouts, drag-and-drop elements, etc.)
• Low-code tools: Adept at rapidly prototyping with Replit, Lovable, etc.

The DNA We Are Looking For

• You are a Builder, not just a Coder. You prefer shipping a live prototype over debating a PR for three days.
• You have Taste. You understand that building for the US consumer market requires a level of polish and minimalism that standard B2B SaaS ignores.
• You are "T-Shaped." You have deep expertise in one area (either scraping or frontend), but you are dangerous enough across the entire stack to build solo.
• You embrace the Chaos. You know how to build structure out of messy unstructured data.

Why Join Now?

• 0 to 1 Ownership: No legacy code, no technical debt. Just you, the founders, and a blank editor.
• Global Impact: You are building from India, but for the most competitive consumer market in the world (USA). The standards are higher, and so is the reward.
• Founding Team Status: Competitive pay with a future path to equity
