Solution Architect (.NET/C#) - Cloud Enablement, Remote: Colombia - Costa Rica, Fulltime.

- This position is open to candidates located in Colombia or Costa Rica only -

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,
