Role Overview

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
• Build distributed systems leveraging event-driven architectures, messaging systems (Kafka, Pub/Sub), and asynchronous processing
• Implement real-time capabilities using WebSockets, Server-Sent Events (SSE), or streaming frameworks
• 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

• Basic 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
