Senior Technical Lead - .Net Fullstack

Integrant Inc is hiring a passionate "Senior Technical Lead - .Net Full-Stack". This role is the technical backbone of the project — owning architecture, engineering standards, and technical quality while partnering with the Technical Project Lead on delivery. Top candidates will demonstrate deep technical expertise across modern .NET, cloud, AI, and distributed systems, with the ability to elevate their team's skills and drive engineering excellence.Duties & Responsibilities:Architecture & System DesignOwn and approve system architecture, design specifications, and technical directionDefine bounded contexts and map context relationships using DDD patterns (Shared Kernel, Customer-Supplier, Anti-Corruption Layers)Design event-driven systems: model domain events, implement async event processing, ensure event idempotency, and handle eventual consistencyDesign microservices communication strategies (sync/async), API gateways, database-per-service patterns, and distributed transaction handlingDesign distributed caching strategies including cache-aside, write-through, and cache invalidation/coherency patternsDesign comprehensive testing strategies: contract testing, integration testing, end-to-end testing, and test data managementAI & AgentsBasic (must have) :LLM integrationSimple RAGSimple AI workflow like n8nPlus:Design and implement multi-agent systems where agents collaborate using coordination frameworks or shared context for complex workflowsImplement operational patterns for multi-agent reliability: retry logic, branching/conditional logic, fallback strategies, and long-running task managementEstablish agent evaluation frameworks — log agent actions, track errors/latency/success rates, and drive continuous improvement through feedback loopsCloud & ServerlessImplement advanced caching solutions using Redis/Azure Cache (strings, hashes, lists, sets, sorted sets, pub/sub)Design complex serverless orchestration: function chaining, fan-out/fan-in workflows, connection pooling, and scalability optimizationDesign API gateway policies: request/response pipelines, hierarchical policy scopes (global, API, endpoint), authentication/authorization mechanisms, and transformation/caching policiesDatabaseDesign and implement database replication (master-slave) and high availability/failover strategiesDevOpsDesign multi-container applications using Docker Compose, manage volumes for data persistence, configure container networking, port mapping, and environment variablesDrive CI/CD pipeline practices and source control workflows across the teamSecuritySecure AI API keys and model endpoints: key rotation, rate limiting, endpoint authentication, TLS, usage monitoring, cost controls, and IP allow listingDesign agent authentication and authorization: agent identity management, service-to-service auth, credential rotation, and inter-agent communication securityUnderstand and apply vulnerability scanning approaches (SAST, DAST, SCA) and tools (SonarQube, Snyk)Engineering Standards & QualityEnforce sound software engineering practices: iterative development, code reviews, unit testing, integration testing, and automation testingReview and sign-off on functional and technical specifications;
