[Hiring] Full Stack Developer @Quantiphi

Role Description

We’re looking for a Full Stack Software Developer to design and build scalable, high-performance applications powering next-generation Agentic AI platforms. In this role, you’ll lead the development of API-first, distributed systems and contribute across the stack from backend microservices to modern frontend experiences. You’ll partner closely with AI/ML teams to integrate LLM-driven workflows, RAG architectures, and multi-agent systems into production-grade applications. This is a hands-on engineering role with strong ownership across architecture, developer experience, and system reliability.

Key Responsibilities

• Design and build scalable full stack applications using React, TypeScript, and Next.js on the frontend and Python (FastAPI) and/or Node.js on the backend.
• Architect and maintain RESTful APIs and microservices with strong versioning, backward compatibility, and API-first design principles.
• Develop distributed systems leveraging event-driven architectures, messaging systems (Kafka, Pub/Sub), and asynchronous processing.
• Build and integrate LLM-powered applications, including RAG pipelines, agentic workflows, and tool-calling frameworks (LangChain, LangGraph).
• Collaborate with AI/ML teams to integrate model serving platforms and orchestrate multi-agent systems.
• Implement real-time capabilities using WebSockets, Server-Sent Events (SSE), or streaming frameworks.
• Ensure high-quality engineering standards across testing (TDD/BDD), CI/CD pipelines, and infrastructure-as-code.
• Deploy and manage cloud-native applications on GCP and/or Azure, leveraging Docker and Kubernetes.
• Champion observability and monitoring using logging, metrics, and tracing (e.g., OpenTelemetry).
• Build developer-friendly tools including SDKs, documentation, and API portals.
• Mentor engineers and contribute to system design, architecture reviews, and best practices.

Qualifications

• 5–10 years of experience in full stack software development.
• Strong expertise in:
  • Frontend: React, TypeScript, Next.js
  • Backend: Python (FastAPI) and/or Node.js
• Proven experience building REST APIs, microservices, and distributed systems.
• Hands-on experience with PostgreSQL and data modeling.
• Experience with Docker, Kubernetes, and cloud platforms (GCP and/or Azure).
• Strong knowledge of CI/CD pipelines (GitHub Actions or similar).
• Experience with API lifecycle management (authentication, versioning, rate limiting).
• Solid understanding of system design, scalability, and performance optimization.
• Experience integrating or building applications with LLMs, RAG, or Agentic AI systems.
• Familiarity with LangChain, LangGraph, or similar frameworks.

Other Qualifications (OQs)

• Experience with:
  • LlamaIndex, advanced LangGraph workflows, or multi-agent orchestration.
  • Prompt engineering and context engineering.
  • Model Context Protocol (MCP) or agent interoperability frameworks.
  • Exposure to GraphQL, gRPC, and advanced API design patterns.
  • Experience with event-driven systems (Kafka, Pub/Sub, Redis).
  • Knowledge of vector databases (pgvector, Pinecone, Milvus).
  • Experience building real-time/streaming UIs (WebSockets, SSE).
  • Understanding of OAuth 2.0, OIDC, RBAC for secure systems.
  • Strong testing practices (TDD, Playwright, contract testing).
  • Experience with OpenTelemetry or similar observability tooling.
  • Familiarity with Domain-Driven Design (DDD) and API-first architecture.

Healthcare Domain Experience (Nice to Have)

• Experience working with FHIR R4, HL7 v2, or SMART on FHIR.
• Integration with EHR systems (e.g., Epic).
• Understanding of HIPAA compliance and healthcare data privacy.
• Exposure to clinical workflows, CDS Hooks, or patient-facing applications.
• Experience building clinical decision support systems or healthcare interoperability solutions.

Benefits

• Make an impact at one of the world’s fastest-growing AI-first digital engineering companies.
• Upskill and discover your potential as you solve complex challenges in cutting-edge areas of technology alongside passionate, talented colleagues.
• Work where innovation happens - work with disruptive innovators in a research-focused organization with 60+ patents filed across various disciplines.
• Stay ahead of the curve - immerse yourself in breakthrough AI, ML, data, and cloud technologies and gain exposure working with Fortune 500 companies.
• If you like wild growth and working with happy, enthusiastic over-achievers, you'll enjoy your career with us!
