Job description

Date Posted: 2026-10-26 Country: India Location: IN-KA-BENGALURU-NORTHGATE ~ Sy No 2/2 Venkatala Village ~ SY NO 2/2 VENKATALA VILLAGE, Yelahanka Hobli Position Role Type: Hybrid At RTX, the world's largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world’s most complex problems. With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can. Together, we push the boundaries of known science and find new ways to connect and protect our world. Join us and help shape the future of aerospace and defense.

What You Will Do

• Design and develop production-quality full-stack AI applications using modern frontend technologies such as React and TypeScript and backend technologies such as Python, Node.js, Java, or .NET.
• Build intuitive user experiences for conversational AI, Generative AI, intelligent workflows, and agentic applications, including streaming responses, dynamic content, citations, evidence, and AI-generated artifacts.
• Develop application-specific backend services, backend-for-frontend APIs, asynchronous workflows, application state, and integrations required to deliver complete end-to-end AI experiences.
• Build human-in-the-loop experiences that allow users to review, approve, modify, reject, pause, resume, cancel, or override AI and agent actions.
• Design application experiences that communicate agent activity, progress, tool execution, uncertainty, partial completion, errors, retries, and recovery.
• Integrate applications with enterprise AI services, agent runtimes, platform APIs, identity services, enterprise applications, data sources, and other backend systems.
• Develop reusable application components and patterns while ensuring accessibility, performance, security, automated testing, maintainability, and alignment with enterprise design systems.
• Partner closely with AI Product Design, Applied AI, Platform Engineering, and product teams from early prototypes through production deployment and continuous improvement.

What You Will Learn

• How modern full-stack engineering changes when applications are powered by LLMs, Generative AI, and autonomous or semi-autonomous agents.
• How to engineer user experiences around probabilistic AI behavior, asynchronous execution, streaming results, uncertainty, human oversight, and failure recovery.
• How enterprise applications securely interact with agents, models, tools, identity systems, enterprise data, and reusable AI platform capabilities.
• How AI applications are designed and operated across a global aerospace and defense company with complex security, data, and integration requirements.
• How emerging AI application patterns, agent interoperability standards, and AI-assisted software development practices are changing modern product engineering.
• How engineers in India collaborate with global AI, product, platform, architecture, and business teams to deliver enterprise AI products.

Qualifications

• A Bachelor's Degree in Computer Science, Software Engineering.
• Minimum of 5 years of relevant professional experience.
• A minimum of 3 years of hands-on full-stack software development experience, including experience building production web applications using modern frontend frameworks and backend APIs or services.
• Strong hands-on experience with JavaScript or TypeScript and a modern frontend framework such as React, Next.js, Angular, or Vue.
• Backend development experience using Python, Node.js, Java, .NET, or similar technologies, including building and consuming REST APIs, microservices, and application services.
• Experience with application architecture, authentication and authorization, state management, asynchronous processing, databases, API integration, and enterprise application integration.
• Strong software engineering fundamentals including source control, code reviews, automated testing, CI/CD, debugging, performance optimization, security, and maintainable code.
• Hands-on experience integrating Generative AI, LLM APIs, AI services, or other AI-enabled capabilities into software applications.
