Role: Full Stack Software Developer

Experience Level: 5-10 yrs

Work Location: US East/Canada (Remote)

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

• 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

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
