(FastAPI preferred)

- Implement secure REST APIs and real-time

communication (WebSockets/streaming)

- Ensure clean separation of concerns across

frontend, API, and data layers

- Build layered backend architectures using FastAPI and dependency

injection

- Implement asynchronous data access patterns and high-performance APIs

- Define API contracts, validation models (Pydantic), and error handling

standards

- Implement authentication and authorization using JWT, OAuth, IAM

Agentic AI Platform Integration Cloud-Native Development

- Build backend services as tools and APIs for

AI agent workflows

- Design APIs providing structured, deterministic

data to LLM orchestration layers

- Support Human-in-the-Loop (HITL): approvals,

callbacks, state management

- Integrate with tool-calling frameworks and external

AI orchestration systems

- Enable agent observability via structured logging,

tracing, and correlation IDs

Frontend Engineering

- Build responsive, accessible UI components

- Implement state management (Redux Toolkit,

Zustand, NgRx, etc.)

- Integrate APIs, handle auth flows, and optimize

performance

- Write unit and integration tests (Jest, React Testing

Library, Angular equivalents)

- Build and deploy services on GCP (preferred), AWS, or Azure

- Implement event-driven architectures (Pub/Sub, messaging systems)

- Work with managed services for compute, storage, and data processing

- Ensure secure configuration, secret management, and scalable deployments

Data Layer & Integration

- Design and implement data access across:

- Relational databases (PostgreSQL / AlloyDB)

- Graph database (Spanner), NoSQL (Firestore)

- Caching (Redis) and analytics (BigQuery)

- Integrate with enterprise systems (SAP, Microsoft Graph, internal APIs)

- Build resilient integrations with retry, timeout, and fault handling

Scope & Expectations

- 100% hands-on engineering role (no people management)

- Collaborate closely with AI/ML engineers on agent workflows

- Participate in design discussions, code reviews, and architecture decisions

- Deliver production-quality, scalable, and maintainable systems

Testing & Quality Engineering

- Write comprehensive tests (pytest, pytest-

asyncio, Jest)

- Cover edge cases, failure scenarios, and

asynchronous workflows

- Follow best practices for code quality,

observability, and maintainability

qualifications:
Required

- 8+ years of full stack software engineering experience

- Strong frontend experience with React or Angular (TypeScript)

- Solid backend development with Python (FastAPI, Flask, or Django)

- Production-grade APIs, microservices, and distributed systems

- Agentic AI concepts: LangGraph, LangChain, tool-calling workflows

- REST APIs, async programming, relational and graph databases

- Hands-on with at least one major cloud provider (GCP preferred)

- Strong testing practices and Git-based workflows

Preferred

- LangGraph or similar agent orchestration frameworks

- Human-in-the-Loop (HITL) workflow patterns

- Model Context Protocol (MCP) or tool integration patterns

- Real-time systems (WebSockets, streaming architectures)

- GCP services: Firestore, Pub/Sub, BigQuery, Cloud Run

- Distributed caching and concurrency patterns (Redis)
