Position: AI Engineer (Conversational Analytics & GenAI Systems)

Location: Bengaluru, India

About the Product:

You will work on IRISS's conversational analytics platform, a GenAI-powered chatbot that

transforms natural language queries into validated, compliant, and tenant-aware SQL and

visual insights. This platform enables users to ask business questions like Show me last

month's motor temperature anomalies in Plant 3 and get immediate, accurate dashboards

and reports generated safely through AI-driven data pipelines.

Our AI stack:

- Interprets user intent using LLMs.

- Generates validated, policy-compliant SQL.

- Executes and visualizes data with context and feedback loops.

- Powers a RAG-based (Retrieval-Augmented Generation) framework integrated with

existing IoT and analytics microservices

Job Overview:

You will design, develop, and maintain the AI chatbot platform that serves as the

intelligence layer for our SaaS ecosystem. This includes architecting end-to-end

conversational pipelines from LLM prompt design to data retrieval, integrating vector-

based search systems and RAG pipelines into our service mesh, leveraging AWS AI/ML and

orchestration services such as Bedrock, Kendra, OpenSearch, Lambda, ECS, and S3 to build

scalable and secure infrastructure, and partnering with full-stack and front-end engineers

to embed AI features directly into user workflows

Backend:

- ASP.NET Core with ABP & ASP.NET Zero modules, EF Core, and SQL Server for tenancy-

aware domain logic

- Python (FastAPI/Flask) for new microservices and migration targets

- APIs: SignalR hubs and REST endpoints exposed through the Web Host

- Infrastructure:

- AWS Services: ECS for container orchestration, RDS (Aurora) for databases, S3 for

storage, Lambda for serverless functions

- Hangfire for background jobs, log4net + custom middleware for correlation-aware

logging

- HealthChecks, Stripe + Firebase integrations

- DevOps: AWS CDK-driven Infrastructure as Code with containerized services, Redis

caching, and microservice extensions

Frontend:

- Angular 18 (latest version with standalone components support)

- TypeScript 5.5

- RxJS 7.4 for reactive programming

- PrimeNG, Angular Material, ngx-charts for UI components

Key Responsibilities:

- Design and implement backend services in .NET Core (ASP.NET Core Web API) using

Entity Framework Core and LINQ

- Help migrate our backend APIs to Python microservices architecture

- Build clean, testable Angular 18+ UIs and reusable components (standalone)

- Design and evolve multi-tenant backend services for assets, sensors, work orders,

notifications, and AI workflows

- Integrate data sources: SQL (SQL Server/Aurora) and InfluxDB for time-series telemetry

- Implement background jobs, rate limiting, and observability using Hangfire, Redis, and log

enrichment patterns

- Extend REST and SignalR endpoints while maintaining tenant isolation and role-based

access control

- Collaborate with IoT and data teams to expose sensor data, alerts, reports, and analytics

- Implement authentication/authorization, input validation, and error handling across the

stack

- Participate in code reviews, ADRs, grooming, and release readiness checks

- Contribute to CI/CD pipelines (GitHub Actions), basic observability, and performance

profiling

- Define service boundaries, transactional integrity, and performance within core

application layers
