Senior Full Stack Engineer(Node.js+ React)

Job Title: Full Stack Engineer – Data & AI

Location: Bangalore

Overview:

As a Full Stack Engineer you will collaborate with a global team of product owners, solution architects, data engineers, and application engineers. Your primary focus will be on developing data-driven web applications and APIs, integrating agentic AI workflows into production applications, and delivering user-facing data products on our UPTIMIZE Platform (Palantir Foundry, AWS). We aim to create data and analytics products that empower data-driven decisions and engage our users. This role focuses on product-grade application development and integration rather than researching ML modeling.

Key Responsibilities:

• Design, develop, test, and maintain state-of-the-art data applications in Palantir Foundry and/or AWS.

• Build data-driven internal applications with web applications and APIs to enable analysts and business users to explore, monitor, and act on data insights.

• Develop and maintain backend services and APIs using TypeScript that integrate with Palantir/AWS and other internal systems.

• Implement and deploy agentic AI workflows using LLM frameworks and cloud-native services, including tool-calling, retrieval-augmented generation, and multi-step reasoning capabilities.

• Integrate AI agents into existing applications through internally built interfaces in data apps and workflow automation.

• Own features end-to-end from design through implementation, testing, deployment, monitoring, and iteration based on user feedback while applying software engineering best practices (code reviews, automated testing, CI/CD, observability).

• Continuously evaluate and improve the user experience of our applications by generating creative ideas for intuitive and visually appealing interfaces.

Requirements:

• 3 to 8 years of experience in software or data engineering focused on production-grade applications and services.

• Bachelor's/master's degree in Computer science, Engineering, Mathematics or related fields.

• Strong proficiency in fronted tech stack TypeScript/JavaScript (Node.js, React) with strong REST API and UI development experience.

• Experience with agentic frameworks (LangChain, LangGraph), cloud-native AI workflows, and AWS deployments preferred.

• Strong communication skills, product mindset, and collaboration skills, with fluency in CI/CD, testing, and observability.

• Familiarity with Python and data processing engines (Spark/Polars/DuckDB), SQL, and ETL/data pipeline development in Palantir Foundry is advantageous.

If you meet the above qualifications and are excited to work with a team of talented professionals in a dynamic environment, we encourage you to apply for this position.
