The Opportunity

As a Senior Software Engineer, you will play a key role in designing, building, and delivering the end-to-end systems that power IruAI. You will work across the stack partnering closely with engineers, product managers, and designers to create reliable, scalable, and intuitive product experiences.

In this role, you will help shape modern system architectures that span frontend, backend, and data layers, ensuring high performance, security, and maintainability. You will contribute to both platform-level services and customer-facing features, taking ownership from concept through delivery.

You will also be instrumental in integrating AI-powered capabilities into the product. This includes working with Large Language Models (LLMs) and AI tooling to build intelligent, user-facing features (such as copilots, automation workflows, and conversational interfaces), as well as internal tools that enhance developer productivity.
