Senior NodeJS Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior NodeJS Engineer based in United States.

The Senior NodeJS Engineer will play a key role in shaping and scaling a rapidly evolving platform designed to support high-growth, global-level services. You will join a newly formed engineering team focused on decoupling a monolithic architecture and building scalable, cloud-native systems capable of handling significant traffic and complexity. This role combines hands-on backend development with architectural decision-making, giving you ownership over both design and implementation. You will collaborate closely with cross-functional teams and a large engineering organization to ensure seamless integration and system reliability. A strong emphasis is placed on performance, scalability, and engineering excellence in a fast-moving Agile environment. This is a high-impact role where your work will directly influence the stability and future growth of the platform.

• Contribute to the design and implementation of scalable backend systems using NodeJS, ensuring high performance, reliability, and maintainability across distributed services.
• Participate in key architectural decisions as part of a team responsible for decoupling and modernizing a large-scale platform.
• Build and optimize APIs, services, and backend components capable of handling increasing traffic and system complexity.
• Collaborate with 40+ engineers and cross-functional stakeholders to ensure smooth integration of new and existing services.
• Troubleshoot and resolve performance bottlenecks, scaling challenges, and system reliability issues across the platform.
• Write clean, testable, and efficient code following best practices in software engineering and cloud-native development.
• Improve infrastructure and deployment processes using modern DevOps practices, enhancing automation and system resilience.

Requirements:

• Proven experience as a Senior NodeJS Engineer building scalable, production-grade backend systems in high-growth environments.
• Strong expertise in NodeJS, Express, and backend architecture design for distributed systems.
• Hands-on experience with cloud platforms such as AWS and containerization tools including Docker and Kubernetes.
• Solid understanding of event-driven architectures and messaging systems such as RabbitMQ, SNS, or Kafka.
• Experience working with databases such as MongoDB and caching systems like Redis.
• Familiarity with infrastructure-as-code tools such as Terraform and CI/CD pipelines.
• Strong problem-solving skills with the ability to troubleshoot complex performance and scaling issues.
• Experience working in Agile teams with strong collaboration and communication skills; English and Portuguese proficiency is a plus.
• Bonus: experience with microservices, distributed systems, and large-scale system design.

Benefits:

• Competitive compensation aligned with senior-level engineering roles in North American markets.
• Flexible working arrangements within a remote-friendly and collaborative engineering culture.
• Opportunity to work on large-scale, high-impact systems serving global enterprise clients.
• Continuous learning environment with training, mentoring, and technical growth opportunities.
• Exposure to modern cloud-native technologies including AWS, Kubernetes, and event-driven architectures.
• Travel opportunities for team collaboration and off-site gatherings.
• Strong engineering culture focused on learning from failure, experimentation, and shared ownership.
