## About the role

As a Full Stack Software Engineer at InstaLILY, you'll own meaningful pieces of our AI agent platform: the core systems that let autonomous agents reason, act, and integrate into our enterprise customers' workflows. You'll work alongside the Lead Software Engineer and a team drawn from top-tier programs to design, build, and ship the platform features that show up in production at our customers.

## What they're looking for

- Bachelor's or Master's in CS, engineering, math, physics, or related: demonstrated ability matters more than credential
- 3–5 years of experience as a software engineer, with a track record of shipping production systems across the full stack
- Strong fluency on the backend (Python, TypeScript, or similar) and the frontend (React, Next.js, modern TypeScript)
- Solid grasp of system design fundamentals (API design, data modeling, async patterns, caching, queues) and frontend architecture (component design, state management, performance)
- Production experience with cloud infrastructure (AWS, GCP, or Azure) and CI/CD pipelines
- AI-serious: you've built and shipped something real with LLMs (a production RAG system, an agent in customer hands, a non-trivial integration), and you have opinions on what works and what doesn't
