Architect (.NET) — AI Platform

Hiring : Architect (.NET) — AI Platform

Experience : 10–15+ years (3–5+ years AI / ML platforms)

Location : Bengaluru / Mysuru / Pune / Kochi

Employment Type : Full-time

About the Role

We are looking for a hands-on . NET Architect to lead the end-to-end design and delivery of an AI-driven platform. This platform powers recommendation engines, NLP search, LLM / SLM integrations, data scraping, and large-scale systems across web, mobile, and messaging channels—with computer vision use cases included.

What You’ll Do

Own the platform architecture on .NET (C#, ASP.NET Core) and cloud-native services (Azure / AWS / GCP)

Ship AI search & recommendations with candidate generation, re-ranking, A / B testing, and pipelines

Integrate large language models (LLMs) & small language models (SLMs) with prompt orchestration and guardrails

Design NLP search combining lexical, semantic, vector retrieval, and relevance evaluation

Build and serve computer vision pipelines (OCR, similarity, detection, moderation) at scale

Guide front-end architecture for AI UX (React, Next.js, TypeScript) focusing on performance and telemetry

Lead mobile AI experiences (.NET MAUI, React Native, Swift / Kotlin), including on-device inference

Design messaging assistants for WhatsApp, Slack, Teams, SMS with workflows and analytics

Oversee data scraping, ingestion, and normalization with ethical and compliant practices

Ensure non-functional excellence : scalability, resiliency, security, latency, compliance, observability

Mentor engineers, run design reviews and RFCs, and produce reference implementations and playbooks

Must-Have Qualifications

Deep expertise in .NET (C#, ASP.NET Core, async I / O, performance, security)

Proven experience architecting AI / ML platforms and deploying production workloads

Hands-on with recommendation engines, NLP search techniques (BM25, embeddings, vector DBs)

LLM / SLM integration experience with Azure OpenAI / OpenAI / local models, prompt routing, caching, safety

Front-end proficiency : React, Next.js, design systems, accessibility, state management, performance

Mobile app experience : .NET MAUI / Xamarin, React Native, Swift / Kotlin, release pipelines, crash analytics

Messaging infrastructure : event streams (Kafka / Event Hubs), chat / bot platforms (Slack, Teams, WhatsApp)

Computer vision : model serving, pipelines, OpenCV, deep learning frameworks familiarity

Strong system design skills for distributed, event-driven systems, caching, partitioning, backpressure

Cloud-native : Azure / AWS / GCP, containers (Docker / Kubernetes), Infrastructure as Code (Bicep / Terraform), CI / CD

Observability expertise : OpenTelemetry, tracing, metrics, dashboards, cost / performance optimization

Excellent communication and cross-functional collaboration skills

Nice to Have

Vector search (Azure AI Search, Elastic / OpenSearch, Pinecone, Weaviate)

LLM tooling (Semantic Kernel .NET, LangChain .NET, guardrails, evaluation harnesses)

MLOps experience (MLflow, SageMaker, Azure ML, streaming / batch pipelines)

On-device ML (Core ML, NNAPI, ONNX Runtime Mobile) and edge computing (WebAssembly / WebGPU)

Push notification & messaging infrastructure (FCM / APNs, webhooks, rate limiting)

Video / image processing at scale with real-time inference pipelines

Tech Stack (Indicative)

Backend : .NET 7 / 8, ASP.NET Core, gRPC / REST, MediatR

Data / Infra : Kafka / Event Hubs, Redis, Postgres / SQL Server, Kubernetes

Search / Semantic : Azure AI Search, Elastic / OpenSearch, vector DBs, RAG pipelines

AI / LLMs / CV : Azure OpenAI, local SLMs, Semantic Kernel, OpenCV, ONNX Runtime, PyTorch / TensorFlow

Frontend : React, Next.js, TypeScript, Tailwind CSS, telemetry, feature flags

Mobile : .NET MAUI, Xamarin, React Native, Swift / Kotlin, OTA updates

Messaging : Slack, Teams, WhatsApp, Twilio, webhook / bot frameworks

Observability : OpenTelemetry, Prometheus, Grafana, App Insights, CloudWatch
