About Us

At Talent2Win, we specialize in connecting top-tier LATAM talent with leading global companies. Our mission is to create meaningful, long-term remote opportunities that empower professionals to grow their careers while making an international impact. We partner with organizations that prioritize engineering excellence, product ownership, and collaboration.

Our Client

Our client is a global leader in Human Experience Management (HXM), offering an all-in-one platform for global payroll, talent management, and compliance. With a presence in over 160 countries, they are redefining the way organizations manage their international workforce. As a fully distributed company, they foster a remote-first culture that values autonomy, ownership, and clear communication.

About the Project

You’ll join a high-performing engineering team working on the evolution of the company’s core product—a platform that supports global HR, payroll, and compliance solutions. The engineering culture emphasizes clean architecture, strong fundamentals, and product thinking. The current focus is on simplifying a complex system built around microservices and microfrontends, modernizing the codebase, and enhancing performance, usability, and scalability. As part of this transformation, you’ll help refactor and build new APIs and backend services, collaborate on architectural decisions, and work closely with cross-functional teams—including VPs and senior stakeholders.

Responsibilities

• Build scalable, high-quality software that powers a global HXM platform.
• Contribute across the stack—from React frontends to Node.js/TypeScript APIs and AWS infrastructure.
• Participate in code reviews, pair programming, and architectural discussions.
• Collaborate with product and design teams to deliver solutions that meet user needs.
• Simplify and modernize existing architecture (microservices, microfrontends).
• Write unit, integration, and smoke tests to ensure product reliability.
• Take ownership of the full development lifecycle—from implementation to monitoring.
• Stay curious and proactive about understanding the full system, including deployment and infrastructure.

Requirements

• 5+ years of experience building software in production environments.
• 3+ years working with modern JavaScript/TypeScript, Node.js, and React.
• Solid understanding of cloud services (AWS preferred, Azure experience is a plus).
• Experience with front-end tools such as React Router, Tailwind CSS, Remix, and accessibility libraries like React Aria.
• Familiarity with infrastructure-as-code tools like Terraform is a plus.
• Strong fundamentals in software engineering (clean code, performance, testing).
• Ability to work across the stack—even if you’re stronger in one area.
• Excellent communication skills and ability to collaborate across disciplines.
• Ownership mindset and eagerness to improve product and engineering practices.

Perks and Benefits

• 100% remote – work from anywhere in LATAM.
• Competitive compensation in USD.
• Opportunity to transition from a contractor position to a full-time role directly with the client.
• Long-term engagement with a globally recognized HR tech company.
• Work closely with senior leadership and influence key decisions.
• Flexible schedule and strong work-life balance.
• Collaborative, feedback-driven engineering culture that values quality and innovation.
