Software Architect – .NET

We’re looking for a hands-on Software Architect to own the architecture of a .NET-based product line that spans multiple systems.

Responsibilities

Define and evolve the architecture for a suite of .NET Core services and web apps (.NET Core, SQL/Postgres, Cognito, Docker, AWS).

Align and integrate frontends built with React, Angular, and Vue with .NET Core backends and external services (Mailgun, Strapi/Node, APIs).

Ensure scalability, security, and reliability across distributed systems and messaging/async processing (e.g., SQS).

Lead modernization (framework upgrades, cloud-native patterns, modularization) and CI/CD practices.

Work closely with product and business stakeholders to translate needs into simple, maintainable solutions and identify opportunities for AI/ML and automation.

Engage with complex and demanding clients, effectively managing expectations, navigating ambiguity, and negotiating technical trade-offs to reach pragmatic, win–win solutions.

Requirements

7+ years in software development, with strong .NET Core / C# and web architecture experience.

Solid background in distributed systems, authN/authZ (OAuth2/OIDC, JWT, Cognito), and relational databases (MySQL, PostgreSQL, SQL Server).

Experience with at least one major frontend framework (React, Angular, or Vue) and cloud (AWS).

Strong Git/CI/CD and automated testing experience.

Excellent communication in English and proven ability to collaborate with non-technical stakeholders.

Demonstrated ability to build trust, handle complex client relationships, and negotiate priorities and scope in high-stakes environments.

Nice-to-Haves

Experience with PHP, Java, or Python in polyglot environments.

Knowledge of Node/Strapi, containers, IaC, and observability tooling.

Practical exposure to AI/ML or data-driven product features.
