Senior Software Engineer (Node.js)
Important: This role is open only to candidates currently living in Mexico or Latin America. Applications from other regions will not be considered.
Join MagmaLabs, a leading provider of expert software engineers dedicated to helping companies achieve their goals across diverse and impactful industries. We are actively seeking a seasoned Senior Software Engineer (Node.js) to join our fully remote team.
In this pivotal role, you will apply your passion for building scalable, high-performance backend systems to solve complex challenges for our clients in healthtech, e-commerce, fintech, and other fast-growing sectors. You will play a key role in designing, developing, and maintaining modern backend architectures powered by Node.js and cloud-native technologies, directly contributing to our clients’ success while driving technical excellence across projects.
About the Role
Are you a seasoned Backend Engineer passionate about building reliable, secure, and scalable systems with Node.js?
As a Senior Software Engineer (Node.js), you will take ownership of architectural decisions, lead backend initiatives, and ensure best practices across high-traffic APIs, SaaS platforms, and distributed systems. You’ll balance delivery speed with long-term maintainability, performance optimization, security, and observability.
Your contributions will directly impact system reliability, developer productivity, and business scalability.
If you thrive on solving complex backend challenges using modern JavaScript/TypeScript ecosystems, we want to hear from you.
Responsibilities
• Lead the architectural design, development, and continuous evolution of scalable backend applications using Node.js (preferably with TypeScript).
• Design and implement RESTful and/or GraphQL APIs with clear versioning, validation, documentation, and error-handling standards.
• Optimize database performance (primarily PostgreSQL), including schema design, indexing strategies, query tuning, and transaction management.
• Implement asynchronous processing, background jobs, and event-driven workflows using modern queue or messaging systems.
• Design resilient integrations with third-party APIs and services (timeouts, retries, circuit breakers, monitoring).
• Ensure code quality and reliability through automated testing (unit, integration, and contract tests).
• Participate in code reviews, maintain high engineering standards, and actively mentor team members.
• Collaborate cross-functionally with product managers, designers, and other engineers to deliver end-to-end solutions.
• Contribute to infrastructure and deployment processes (Docker, Kubernetes, CI/CD pipelines).
• Improve production reliability through monitoring, logging, tracing, and performance optimization.
• Maintain clear technical documentation, including architecture decisions and operational guidelines.
• Take ownership of complex technical initiatives and drive them to completion independently.
Requirements
• Minimum of 7 years of software development experience, with at least 5 years focused on backend development using Node.js in production environments.
• Strong proficiency in TypeScript (or modern JavaScript with willingness to work in TypeScript).
• Experience with backend frameworks such as NestJS, Express, or Fastify.
• Solid expertise with relational databases (preferably PostgreSQL), including schema design and query optimization.
• Experience with caching and/or asynchronous processing systems (e.g., Redis, message brokers, queues).
• Hands-on experience with automated testing frameworks (e.g., Jest or similar) and CI/CD pipelines.
• Strong understanding of secure backend practices (authentication, authorization, input validation, secrets management, rate limiting).
• Experience working with containerization and cloud environments.
• Proficiency with Git and collaborative development workflows.
• Strong problem-solving skills and ability to thrive in a remote-first environment.
• Excellent communication skills in English.
• Demonstrated ability to take initiative and lead technical decisions independently.
• Experience working within Agile development methodologies (Scrum, Kanban, etc.).
Bonus Points If You Have
• Experience designing microservices or refactoring monolithic systems.
• Experience with event-driven architectures.
• Familiarity with GraphQL or advanced API contract design.
• Experience with Amazon Web Services, Google Cloud, or Microsoft Azure.
• Hands-on experience with Docker and container orchestration.
• Knowledge of distributed tracing and observability practices.
• Exposure to frontend frameworks such as React.js.
• Contributions to open-source projects or technical publications.
