About Intro

Intro is a dating app where LGBTQ South Asians find love. Built by Queer Desis in New York for the 100 million queer South Asians around the globe who deserve a space of their own. Our mission: help 1 million Queer Desis find love by the end of 2026. We’re creating a safer, more intentional, and community-driven dating experience — one that celebrates identity, culture, and connection.

The Role

We’re looking for a Founding Full-Stack Engineer who thrives in 0→1 environments. You’ll take ownership of architecture, design, and execution across backend, web, and mobile (iOS/Android) — helping shape both the product and the culture of the company.

You’ll be joining at the earliest stage — working directly with the founding team on everything from feature development to infrastructure decisions and product strategy.

Responsibilities

• Architect and build scalable backend systems (APIs, data models, authentication, messaging, matching).
• Lead development across web and mobile clients (React, React Native, Swift/Kotlin).
• Collaborate on product design and iterate quickly on user feedback.
• Set up CI/CD, testing, and monitoring pipelines.
• Help define the tech culture, best practices, and early engineering team standards.
• Contribute to early hiring and mentorship as we grow.

You Might Be a Great Fit If You

• Care deeply about building for LGBTQ and South Asian communities.
• Are motivated by impact and ownership, not just code.
• Thrive in ambiguity and love solving real user problems fast.
• Want to help define the technical and cultural DNA of a mission-driven company.

Interview Process

1. AI Screen – Initial automated technical and culture-fit assessment.
2. Web Challenge – Build a small feature for the web app to demonstrate frontend and full-stack skills.
3. iOS Challenge – Build a small feature for the iOS app to showcase mobile development and design sense.
4. Android Challenge – Build a small feature for the Android app to highlight cross-platform depth.
5. Founder Chat – Meet with the Founder to discuss vision, values, and long-term fit.

What We Offer

• Competitive salary.
• Full-time (40 hours/week) with flexible hours.
• Opportunity to shape a product with global cultural impact.
• Work directly with the founding team building something that truly matters.

Design and develop scalable web applications using MEAN/MERN stack.

Build & optimize AI/LLM workflows using LangChain or LangGraph.

Implement vector storage & semantic search using FAISS / Pinecone / Chroma / Milvus.

Build APIs, microservices, and integration layers.

Optimize application performance and ensure code quality.

Collaborate with cross-functional teams (product, design, backend, DevOps).

Must-Have Skills

• Strong experience in Node.js, Express.js, MongoDB, and Angular/React.
• Hands-on experience in LLM apps, RAG pipelines, Vector Databases.
• Practical knowledge of LangChain / LangGraph.
