AI Internship Hackathon
OneInbox AI Internship Hackathon
Build. Ship. Get Hired.
Think you have what it takes to build production-ready AI systems?
The OneInbox AI Internship Hackathon is a hiring-first engineering challenge where exceptional builders compete for paid internship opportunities across AI Engineering, Voice AI Engineering, and Backend Development.
This isn't a hackathon for slide decks or AI wrappers. You'll solve real engineering problems inspired by production systems and showcase your skills directly to the OneInbox Engineering Team.
Internship Opportunities
We're hiring for:
AI Engineer Intern
Voice AI Engineer Intern
Backend Developer Intern
💰 Stipend: ₹20,000–₹25,000/month (based on performance)
Hackathon Format
Round 1 — Online Architecture Challenge
Design your solution before writing code.

📍 OJONE, Bengaluru
📅 Timeline
Round 2 Starts — 16th July | 10:00 PM IST
Build Sprint — 16th July – 22nd July
Final Submission Deadline — 22nd July | 9:00 PM IST
Top 20 Finalists Announcement — 22nd July | 11:59 PM IST
Offline Hiring Finale — 25th July | 2:00 PM IST onwards
Shortlisted participants will build a complete production-ready AI agent using their Round 1 architecture as the foundation.
All projects must be submitted by 22nd July, 9:00 PM IST. After evaluation, the Top 20 builders will be shortlisted and invited to OJONE, Bengaluru for the Offline Hiring Finale.
During the finale, the Top 20 finalists will present their AI agents to the judges through live demonstrations and technical discussions. Based on the final evaluation, one builder from each domain (AI Engineer, Voice AI Engineer, and Backend Developer) will receive an internship offer from the OneInbox Engineering Team.
Problem Statements
Participants can choose one Problem Statement from the following domains:
AI Engineer
Problem Statement 1 - Self-Correcting RAG Pipeline :
Build a RAG system that identifies insufficient or conflicting context and intelligently re-queries or asks for clarification instead of hallucinating. Measure improvements by comparing hallucination rates before and after introducing the self-correction layer.
Problem Statement 2 - Constrained Structured Extraction at Scale :
Extract structured JSON from noisy real-world documents while strictly following a predefined schema. The solution should achieve high schema accuracy at scale without relying on hardcoded regex-based extraction.
Voice AI Engineer
Problem Statement 3 - Interruption-Aware Voice Agent :
Develop a real-time voice agent that gracefully handles user interruptions, updates context, and continues conversations naturally. Demonstrate seamless multi-turn interactions with interruption handling in action.
Problem Statement 4 - Low-Latency Multilingual Voice Pipeline :
Build a multilingual voice-to-voice pipeline capable of switching languages mid-conversation without restarting the workflow. Optimize the system to deliver fast, low-latency responses with real performance measurements.
Backend Developer
Problem Statement 5 - Rate-Limited Multi-Tenant API Gateway :
Design a scalable API gateway that supports multiple AI providers with tenant-specific rate limiting, failover, and intelligent request queueing. Validate the system through concurrent load testing and reliability benchmarks.
Problem Statement 6 - Event-Driven Pipeline with Guaranteed Delivery :
Build a fault-tolerant asynchronous job processing pipeline with retries, idempotency, dead-letter queues, and observability. Ensure jobs are never lost or duplicated, even during worker failures.
Open Innovation Track
Problem Statement 7 - Have your own idea?
Build an original solution under AI Engineering, Voice AI Engineering, or Backend Development that matches the technical complexity of the official challenges.
