About the role

We’re seeking a highly experienced, hands-on Principal .NET Consultant who combines deep technical mastery of the .NET ecosystem with exceptional client-facing, leadership, and communication skills. You will lead complex delivery engagements, architect robust solutions, mentor teams, and serve as a trusted advisor to clients—translating business needs into secure, scalable, and maintainable .NET solutions.

Responsibilities

• Lead end-to-end client engagements: discovery, solution design, delivery, and post-go-live support
• Build and maintain strong executive-level relationships; act as a trusted technical advisor
• Facilitate requirements workshops, steer scope and expectations, and negotiate trade-offs
• Mentor senior and mid-level engineers; foster a culture of quality, ownership, and continuous improvement
• Contribute to pre-sales: estimates, proposals, solution narratives, and technical win strategies
• Design and implement enterprise-grade solutions using modern .NET (e.g., .NET 8/9, ASP.NET Core, C#)
• Own critical components: domain modeling, API design, performance tuning, security, and observability
• Define architecture patterns (clean architecture, DDD, microservices, event-driven) and enforce coding standards
• Drive DevOps practices: CI/CD pipelines, infrastructure automation, and cloud-native deployments (Azure/AWS)
• Perform code reviews, troubleshoot complex issues, and occasionally write production code to unblock teams
• Establish quality gates, testing strategies (unit/integration/load), and reliability practices
• Identify technical risks early and lead mitigation plans; ensure compliance and security best practices
• Measure outcomes and iterate: track KPIs, gather feedback, and refine solutions over time

Qualifications

• 10+ years of professional software development, with 6+ years focused on .NET
• Expert-level C# and deep knowledge of .NET frameworks: ASP.NET Core, EF Core, Web APIs, background services, gRPC as needed
• Strong experience with:
  • Cloud platforms (Azure and/or AWS), containers (Docker/Kubernetes), and serverless patterns
  • Data access and performance (SQL Server, PostgreSQL, caching, message brokers like Azure Service Bus/Kafka/RabbitMQ)
  • Security (OAuth2/OIDC, JWT, secrets management), observability (OpenTelemetry, structured logging, metrics)
• Demonstrated ability to make sound technology choices and justify them to both engineers and business stakeholders
• Proven track record leading client engagements and delivering complex projects on time and within scope
• Excellent communication: able to explain complex technical concepts clearly to non-technical audiences
• Strong facilitation, negotiation, and stakeholder management skills; comfortable in executive conversations
• Experience mentoring engineers, leading design reviews, and elevating team capability
• Comfortable in a consulting environment: travel as needed, multi-client context, and shifting priorities
