Solution Architect (.NET/C#) - Cloud Enablement

The Solution Architect plays a critical role in shaping and evolving cloud-enabled application architecture to deliver
secure, scalable, resilient, and business-aligned solutions. This hands-on role combines technical roadmapping,
solution design, independent research, application development, and close collaboration with engineering teams

and stakeholders.

The ideal candidate combines strong .NET and Azure expertise with practical architecture thinking, modern DevOps
and infrastructure-as-code experience, and the ability to communicate complex technical concepts clearly. This
person can move between strategic architecture and hands-on delivery, turn ambiguous challenges into wellsupported
recommendations, and help define executable work for others.

Key Responsibilities

Technical Leadership and Delivery

• Define technical roadmaps and architecture strategies for cloud migration, application modernization, and
  scalable digital solutions.
• Design secure, scalable, resilient, and highly available systems that align technical decisions with business
  objectives.
• Balance long-term architecture direction with hands-on development, prototyping, technical validation, and
  delivery support.
• Research architecture options, evaluate tradeoffs and risks, and present clear recommendations to
  engineering teams and stakeholders.
• Produce architecture diagrams, decision records, technical plans, and system representations that make
  complex designs easy to understand.
• Translate architecture into executable work by helping define epics, features, stories, dependencies, and
  technical sequencing.
• Design security-first solutions that protect customer and enterprise data, support compliance, and reduce
  operational risk.
• Collaborate with architects, engineering leaders, product partners, and business stakeholders to align
  solutions with enterprise standards and delivery priorities.

Database and Performance Optimization

• Design data and integration architectures that support scalability, reliability, maintainability, and future
  growth.
• Write and review advanced SQL, data models, indexing strategies, and query plans to improve application
  and database performance.
• Identify and address performance bottlenecks across applications, services, integrations, and databases.
• Design APIs, third-party and vendor integrations, and synchronous or asynchronous communication
  patterns.
• Define service boundaries, integration contracts, versioning approaches, error-handling strategies, and data
  integrity controls.
• Support distributed and event-driven solutions using technologies such as Azure Service Bus, Kafka, or
  RabbitMQ.

Cloud and DevOps

• Design and support solutions in Microsoft Azure using secure, scalable, and repeatable cloud patterns.
• Help migrate applications and services from on-premises environments to Azure.
• Define and improve application onboarding patterns that enable engineering teams to move workloads into
  the cloud consistently.
• Use infrastructure-as-code and deployment tooling, including Bicep, Helm, GitHub Enterprise, and GitHub
  Actions workflows.
• Apply Agile and DevOps practices to improve delivery quality, deployment reliability, collaboration, and
  continuous improvement.
• Promote observability, resilience, fault isolation, secure configuration, and operational readiness across
  cloud solutions.
• Partner with engineers to troubleshoot architecture, environment, integration, deployment, and operational
  issues.

Full-Stack Development

• Design and build backend services using C#, .NET, .NET Core, Web APIs, web applications, and servicebased
  architectures.
• Remain close enough to the code to validate designs, support implementation, and contribute hands-on
  when needed.
• Build and support modern front-end applications using JavaScript, TypeScript, and frameworks such as
  Vue.js, React, or Angular.
• Design and evaluate secure authentication and authorization solutions for external users and customerfacing
  applications through an Identity Provider (IdP), using OAuth 2.0, OpenID Connect, JWT, and
  platforms such as Microsoft Entra ID, Duende IdentityServer v8, or OpenIddict.
• Support customer identity and access management modernization by evaluating and adopting Microsoft
• Entra External ID, including secure migration paths from Azure AD B2C or other legacy identity platforms.
• Promote clean, maintainable, testable code and sound engineering practices across the software
  development lifecycle.
• Support modernization of legacy applications and the evolution of monolithic systems toward appropriate
  modular, service-based, distributed, or event-driven designs.

Mentorship and Team Development

• Mentor engineers through pairing, design reviews, code reviews, knowledge-sharing sessions, and technical
  discussions.
• Bring ideas forward, encourage constructive brainstorming, and help teams evaluate multiple solution
  options.
• Communicate proactively and clearly in a distributed, cross-functional environment.
• Influence stakeholders and align technical decisions with business objectives, customer needs, delivery
  constraints, and risk considerations.
• Research unfamiliar technical areas independently and share findings in a clear, actionable way.
• Foster a culture of ownership, accountability, curiosity, collaboration, quality, and continuous improvement.

Required Qualifications

• High school diploma or equivalent required. Bachelor's degree in Computer Science or a related field
  preferred.
• 8 to 10 years of software development experience, including technical leadership or architecture
  responsibilities.
• 2 or more years of experience creating technical roadmaps and presenting architectural solutions.
• Strong hands-on experience designing and developing solutions with C#, .NET, .NET Core, Web APIs, and
  the broader Microsoft technology stack.
• Strong Microsoft Azure experience, including cloud migration, cloud-native solution design, and application
  modernization.
• Hands-on experience with infrastructure as code and delivery automation, including Bicep, Helm, GitHub
• Enterprise, and GitHub Actions or comparable tooling.
• Hands-on experience designing and implementing external-user authentication and authorization through an
• Identity Provider, using OAuth 2.0, OpenID Connect, and JWT.
• Practical experience with at least one relevant identity platform, such as Microsoft Entra ID, Duende
• IdentityServer v8, OpenIddict, Azure AD B2C, or Microsoft Entra External ID.
• Experience with distributed systems, asynchronous communication, and event-driven architecture.
• Strong understanding of API design, third-party integrations, SQL development, data modeling, indexing,
  and performance optimization.
• Experience with JavaScript or TypeScript and at least one modern front-end framework such as Vue.js,
  React, or Angular.
