Mid-Level Fullstack Engineer

We need an English-fluent Mid-Level Fullstack Engineer, based in Latin America (preferably Brazil), available to work remotely.
We are looking for someone with exceptional communication and relationship-building skills, who embraces changes while maintaining strong attention to detail. An interested and proactive person, who's constantly learning and improving their skills.

Are you the one we are looking for?

You will be the bridge between our data layer and our user interface. Working alongside our Front-End and AI engineers, you will build the robust back-end services necessary to power new features, while also jumping into the React/Next.js codebase to help push user-facing features across the finish line.

Responsibilities:

• Design, build, and maintain scalable back-end services and APIs using C# and .NET.
• Deploy and manage application infrastructure within the Azure cloud ecosystem.
• Develop and maintain secure integrations with complex third-party APIs (e.g., external tracking systems, secure payment/billing gateways, and communication tools).
• Support the front-end team by building full-stack features end-to-end, utilizing React and Next.js when required.
• Design and optimize database schemas to support heavy operational data and performance metrics.
• Collaborate effectively via GitHub, writing clean, well-documented, and testable code.

Requirements:

• 3+ years of full-stack software development experience.
• Strong back-end experience with C# and .NET, including building RESTful APIs.
• Solid experience with cloud platforms, preferably Microsoft Azure (App Services, SQL Database, Functions, etc.).
• Proven ability to work on the front-end using React and Next.js.
• Experience migrating, mapping, and integrating third-party APIs (such as CRMs, ATS platforms, or payment providers).
• Ability to troubleshoot across the entire stack and work collaboratively to meet rapid release cycles.
