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.
How You'll Make a Difference Day to Day:
Build and Maintain Full-Stack Features: Design, develop, and maintain both backend services and user-facing applications that power core product functionality end-to-end.
Contribute to System Architecture: Work across the stack to design scalable architectures spanning frontend, backend, and data layers, ensuring performance, reliability, and maintainability.
Develop AI-Powered Features: Build AI-driven capabilities that surface directly in user experiences, integrating LLM APIs into both backend services and frontend workflows.
Improve Developer Workflows: Enhance full-stack developer experience, including frontend tooling, local environments, CI/CD pipelines, and testing workflows.
Build Scalable Systems: Develop scalable systems across frontend and backend layers, optimizing performance from API to UI.
Implement Messaging and Integration Patterns: Build event-driven systems and ensure seamless integration between backend services and real-time frontend experiences.
Collaborate Across Teams: Partner closely with product managers, designers, and engineers to deliver cohesive end-to-end user experiences.
Write High-Quality Code: Maintain high standards across frontend and backend codebases, including testing, code reviews, and performance optimization.
Continuously Improve the Platform: Improve both user experience and system performance by addressing technical debt across the full stack.
