About DaCodes

At DaCodes, we build high-impact software solutions for startups and general 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 (Net Suite, 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
