About DaCodes

At DaCodes, we build high-impact software solutions for startups and global companies across LATAM and the U.S. We work with senior teams who value ownership, technical excellence, and high-quality engineering standards.

Role Overview

We are looking for a Senior Backend Engineer with a strong focus on integrations, capable of designing, implementing, and maintaining robust, scalable, and secure backend systems, primarily using Node.js, APIs, and event-driven architectures.

This is not a low-code configuration role. It requires deep understanding of backend engineering, protocols, concurrency, and security.

Why this role is interesting

• Work on complex backend systems and real-world integrations (SaaS, APIs, ERPs)
• Solve challenges around scalability, reliability, and distributed systems
• Collaborate with a highly senior team with strong technical ownership
• Work directly with U.S.-based clients and products with real impact

What You’ll Do

• Design and build scalable backend services using Node.js
• Develop and maintain robust, secure APIs
• Work on integrations between SaaS platforms, ERPs, and internal systems
• Implement event-driven flows (webhooks, retries, idempotency)
• Contribute to authentication and authorization flows (OAuth2, JWT, API keys)
• Identify and solve performance, concurrency, and scalability challenges
• Improve observability, logging, and error handling in production
• Participate in technical decisions and architecture discussions

Requirements

• 4+ years developing backend systems in production, with experience in integrations and distributed architectures.
• Strong experience with Node.js in production environments
• Experience building and working with APIs
• Familiarity with authentication and authorization mechanisms (OAuth2, JWT or similar)
• Experience integrating with external systems or third-party services
• Solid understanding of backend fundamentals (performance, scalability, reliability)
• Advanced English (you’ll work with U.S. clients)

Nice to Have (Not Required)

• Experience with event-driven architectures or webhooks
• Experience with iPaaS tools (Mulesoft, Workato, Boomi, etc.)
• Experience integrating with ERPs (NetSuite, SAP, Business Central)
• Experience with high-concurrency systems
• Familiarity with CI/CD practices

How we work

• Remote-first culture
• High ownership and autonomy
• Focus on clean, maintainable, production-grade code
• Collaborative, senior-level environment
