Senior Technical Lead – .Net Full-Stack

Role Overview

• Own and approve system architecture, design specifications, and technical direction.
• Define 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 consistency.
• Design microservices communication strategies (sync/async), API gateways, database-per-service patterns, and distributed transaction handling.
• Design distributed caching strategies including cache-aside, write-through, and cache invalidation/coherency patterns.
• Design comprehensive testing strategies: contract testing, integration testing, end-to-end testing, and test data management.
• Design and implement multi-agent systems where agents collaborate using coordination frameworks or shared context for complex workflows.
• Implement operational patterns for multi-agent reliability: retry logic, branching/conditional logic, fallback strategies, and long-running task management.
• Establish agent evaluation frameworks — log agent actions, track errors/latency/success rates, and drive continuous improvement through feedback loops.
• Implement 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 optimization.
• Design API gateway policies: request/response pipelines, hierarchical policy scopes (global, API, endpoint), authentication/authorization mechanisms, and transformation/caching policies.
• Design and implement database replication (master-slave) and high availability/failover strategies.
• Design multi-container applications using Docker Compose, manage volumes for data persistence, configure container networking, port mapping, and environment variables.
• Drive CI/CD pipeline practices and source control workflows across the team.
• Secure AI API keys and model endpoints: key rotation, rate limiting, endpoint authentication, TLS, usage monitoring, cost controls, and IP allow listing.
• Design agent authentication and authorization: agent identity management, service-to-service auth, credential rotation, and inter-agent communication security.
• Understand and apply vulnerability scanning approaches (SAST, DAST, SCA) and tools (SonarQube, Snyk).
• Enforce sound software engineering practices: iterative development, code reviews, unit testing, integration testing, and automation testing.
• Review and sign-off on functional and technical specifications; monitor deliverables vs. specifications and provide corrective actions.
• Champion best practices in design patterns, SOLID principles, and clean architecture.
• Mentor and train team members on software design, design patterns, SOLID principles, and emerging technologies.
• Conduct code reviews that are educational — raise the engineering bar for the whole team.
• Assess team capabilities and advise the Technical Project Lead on task assignments based on technical strengths.
• Provide technical feasibility assessments and effort estimates for scope reviews and change requests.
• Supply technical input for risk assessments, status reports, and delivery decisions.
• Support client-facing technical discussions and demos when deep technical context is needed.

Requirements

• 9+ years of experience in software engineering.
• 2+ years as a Lead Software Engineer with hands-on technical leadership of cross-functional teams.
• Strong hands-on experience with .NET Core, C#, and the modern .NET ecosystem.
• Proficient with frontend technologies (Angular or React).
• Hands-on experience with software architecture: DDD, Event-Driven Architecture, microservices, and distributed systems.
• Experience designing and implementing multi-agent AI systems and agent observability.
• Hands-on with cloud platforms (Azure and/or AWS) including serverless, caching, and API management services.
• Experience with database replication, high availability, and failover strategies.
• Hands-on with DevOps tools: CI/CD, source control, Docker, Docker Compose, and Kubernetes.
• Understanding of security practices: vulnerability scanning (SAST/DAST/SCA), AI endpoint security, and agent authentication.
• Agile methodology experience.
• Strong client engagement skills — this role requires regular interaction with US clients.
• Self-learner who stays current with software development trends.
