Job Summary:
We are seeking a highly skilled Architect / Lead .NET Developer to design and deliver secure, scalable cloud-first solutions on Microsoft Azure. The ideal candidate will have deep expertise in .NET (C#), modern architecture and design patterns, SQL Server, and Azure PaaS, with hands-on experience guiding engineering standards, CI/CD, and application modernization.
Key Responsibilities
- Own solution architecture and technical design for .NET-based applications, ensuring scalability, reliability, security, and maintainability.
- Design and build APIs and services using .NET (C#), applying SOLID principles and design patterns (e.g., Factory, Strategy, Repository, CQRS where appropriate).
- Define and enforce architecture standards, coding guidelines, and reusable patterns to improve overall engineering quality.
- Collaborate with product owners, stakeholders, and cross-functional teams to translate business needs into technical architecture and delivery plans.
- Build and govern CI/CD pipelines using Azure DevOps implement branching strategies, quality gates, and automated deployments.
- Design, deploy, and operate solutions on Azure PaaS (e.g., App Service, Functions, Azure SQL, Storage, Service Bus/Event Grid) with cost, performance, and resiliency in mind.
- Lead troubleshooting and performance tuning across application, database, and Azure resources drive root-cause analysis and preventative fixes.
- Mentor engineers, conduct architecture/design reviews, and lead code reviews to ensure alignment with standards and patterns.
- Drive modernization initiatives (e.g., monolith to microservices, legacy to cloud) including roadmap, patterns, and migration strategy.
- Evaluate technology options and make high-level architectural decisions (trade-offs, NFRs, scalability, observability, and security).
- Embed security best practices (OWASP, secrets management, identity and access, secure SDLC) into design and delivery.
- Create and maintain architecture artifacts and technical documentation (HLD/LLD, API specs, runbooks, ADRs).
- Champion continuous improvement by staying current with .NET/Azure best practices and recommending pragmatic adoption.
- Partner with stakeholders to gather, clarify, and refine requirements, including non-functional requirements (availability, latency, scalability, compliance).
- Lead and contribute to agile ceremonies (planning, stand-ups, reviews, retrospectives) to ensure predictable delivery and cross-team alignment.
- Establish observability standards (logging, metrics, tracing) and ensure monitoring/alerting is implemented using approved tools (e.g., Datadog/Azure Monitor) with SLOs where applicable.
Qualification:
- 9+ years of experience in software development.
- Strong hands-on expertise in .NET (C#) including Web API, asynchronous programming, performance optimization, and secure coding.
- Strong experience with SQL Server data modelling, query optimization, and integration patterns.
- Strong understanding of architecture styles including microservices, event-driven design, and API-first approaches.
- Strong understanding and practical application of design patterns and principles (SOLID, GoF patterns) and clean architecture.
- Hands-on experience designing serverless and integration solutions using Azure Functions and messaging/eventing services.
- Hands-on experience with Azure PaaS and cloud architecture (App Service, Azure SQL, Storage, Key Vault, networking fundamentals, scaling and resiliency patterns).
- Experience with Azure DevOps (Repos, Pipelines) and CI/CD practices exposure to release governance and Infrastructure as Code is a plus.
- Experience implementing observability using monitoring/logging tools (e.g., Datadog, Azure Monitor, Application Insights).
- Excellent problem-solving skills and attention to detail.
- Strong communication and teamwork skills.
Preferred Qualification:
- Infrastructure as Code (IaC) using Terraform/Bicep/ARM templates.
- DevSecOps experience: integrating security scanning, secrets, and policy controls into CI/CD pipelines.
- Automated testing practices (unit/integration/contract tests) and test strategy for distributed systems.
- API governance and management using Azure API Management (policies, versioning, security, throttling).
