Position Overview

We are seeking a highly sophisticated, systems-minded Senior Fullstack Engineer to join our growing global Engineering cell in a full-time remote contractor capacity within Argentina. Working in close collaboration with our strategic client—a global integration partner specializing in the digital media supply chain—you will assume absolute individual accountability for building, maintaining, and scaling large-scale single-page web applications (SPAs). Moving completely past boilerplate code fixes, you will act as a primary full-stack owner, managing complex application state matrices, integrating robust RESTful web services, and auditing pull requests to enforce rigid quality standards. This high-agency role demands a seasoned JavaScript/TypeScript authority who excels at cross-layer troubleshooting, loves a culture of deep technical ownership, and can smoothly align delivery milestones with distributed organizational stakeholders.

Key Responsibilities

• Single-Page Application Engineering: Design, develop, and refactor high-performance, responsive single-page web applications (SPAs) equipped with intricate runtime state management layers.
• Interactive Frontend Layout Programming: Code modular, maintainable user interfaces natively utilizing React, TypeScript, HTML5, and CSS3.
• Responsive Component Styling: Implement modern visual hierarchies and layout designs across customer-facing web spaces leveraging frameworks like Tailwind, Bootstrap, or Material UI.
• NodeJS Server-Side Development: Model, secure, and maintain scalable full-stack backend routers and RESTful APIs using Node.js web frameworks (specifically Express.js or Hapi.js).
• Multi-Engine Database Instrumentation: Manage structural data persistence layers, designing and optimizing performant queries across relational and non-relational database environments like PostgreSQL, MongoDB, MySQL, or MSSQL.
• Rigorous Testing Quality Assurance: Author and execute comprehensive automated unit and integration testing blocks using Jest, Cypress, or Chai to preserve continuous application stability.
• Collaborative Code Auditing: Conduct thorough peer code reviews, verifying security hygiene and code reusability while actively fostering knowledge sharing across distributed development teams.
• Stakeholder Onboarding Alignment: Onboard and collaborate tightly alongside internal project owners and key stakeholders to map technical guidelines and ensure unconditional adherence to client product standards.

Required Skills & Qualifications

• 5+ years of verified professional history running native Full Stack Web Development, distributed application architecture, or enterprise software delivery.
• Expert-tier programming literacy across foundational web technologies, encompassing JavaScript, TypeScript, and modern frontend frameworks like React, Angular, or Vue.js.
• Hands-on operational experience building and launching server-side application routing architectures natively inside the Node.js ecosystem.
• Practical data engineering familiarity configuring and executing schema scripts within database structures like MongoDB or PostgreSQL.
• Demonstrated experience configuring automated unit and integration tests using libraries such as Jest or Cypress.
• Deep underlying comprehension of version control systems, highlighting structured asset management workflows natively within Git.
• Outstanding verbal and written communication mechanics, with an absolute capacity to analyze client criteria and explain architectural trade-offs clearly.
• Location Context: Contract-based parameters open exclusively to qualified full-stack engineering leads permanently based anywhere within Argentina to execute from home under 100% remote conditions.

Preferred Strategic Indicators (Nice to Have)

• Prior experience building or securing software systems natively inside the Media & Entertainment, Solar Energy, or corporate Compliance sectors.
• Hands-on integration experience working alongside enterprise application suites, specifically SAP / BTP (Business Technology Platform) ecosystems.
• Practical background deploying and scaling microservice containers across major cloud service providers like AWS, Azure, or Google Cloud.

What We Offer

• The exceptional professional canvas to directly direct, code, and expand the full-stack web platforms delivering vital media supply chains to global audiences.
