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
