Senior Full-stack Engineer (React/Node) (Backend-Focused) - Real Estate

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Full-stack Engineer (React/Node) (Backend-Focused) - Real Estate based in Brazil.

This is a high-impact engineering opportunity focused on building resilient, scalable, and data-intensive systems for a technology-driven real estate environment.
You will own features end-to-end, from PostgreSQL schema design and distributed backend services to polished React and Next.js experiences.
The role places a strong emphasis on reliability, data integrity, asynchronous processing, and operational excellence.
You will design systems that integrate with third-party platforms through webhooks, queues, retries, and reconciliation workflows.
Working within an autonomous engineering environment, you will influence architecture, mentor teammates, and contribute to technical standards.
Modern AI-assisted development tools will be part of the engineering workflow, helping accelerate delivery while maintaining high-quality software practices.
This role is ideal for a systems-minded engineer who enjoys ownership, complex technical challenges, and building production-grade solutions.

• Own the full lifecycle of product features, from database schema design and backend implementation through frontend development, deployment, and production monitoring.
• Design, develop, and maintain scalable event-driven and distributed systems with strong reliability and data-consistency guarantees.
• Build and optimize PostgreSQL schemas, queries, migrations, and transactional workflows for high-performance applications.
• Develop resilient integrations with third-party systems using webhooks, queues, retry mechanisms, and reconciliation processes.
• Implement reliability patterns such as idempotency, dead-letter queues, outbox patterns, and fault-tolerant asynchronous processing.
• Build responsive, high-quality user interfaces using React, Next.js, and modern TypeScript practices.
• Contribute to architectural decisions and continuously improve scalability, observability, reliability, and operational excellence.
• Use AI-assisted development tools such as Claude Code or comparable agentic coding platforms to improve engineering productivity and delivery speed.
• Participate in code reviews, mentor engineers, and promote strong engineering practices for sensitive financial and transactional data.
• Collaborate with product, design, and engineering stakeholders to deliver intuitive and reliable user experiences.
• Implement and maintain monitoring and observability solutions using platforms such as Datadog or OpenTelemetry.
• Contribute to infrastructure automation and cloud resource management using Infrastructure as Code tools such as Terraform or Pulumi.
• Ensure solutions follow appropriate security, compliance, and regulated-environment requirements, including SOC2 and PCI-DSS standards where applicable.

Requirements:

• 5+ years of experience as a Full-Stack Engineer building and delivering production-ready applications end-to-end.
• Strong proficiency in TypeScript and Node.js, with advanced experience in React and Next.js.
• Deep expertise in PostgreSQL and database engineering, including raw SQL, query optimization, migrations, and performance analysis.
• Proven experience designing and maintaining event-driven and distributed systems.
• Strong understanding of reliability engineering patterns, including idempotency keys, retry strategies, dead-letter queues, outbox patterns, and reconciliation processes.
• Experience designing webhook-driven architectures and integrating third-party systems.
• Strong understanding of scalable architectures, asynchronous processing, fault tolerance, and distributed-system behavior.
• Experience working with financial, payments, billing, payroll, ledgering, or other high-transaction-volume systems.
• Hands-on experience with AI-assisted development tools such as Claude Code or similar agentic coding platforms.
• Strong problem-solving and systems-thinking skills, with particular attention to edge cases, reliability, and data integrity.
• Excellent communication skills and the ability to work autonomously within high-impact engineering teams.
• Experience with Infrastructure as Code tools such as Terraform or Pulumi is a plus.
• Familiarity with observability platforms such as Datadog or OpenTelemetry is advantageous.
• Experience in regulated or compliance-heavy environments, including SOC2 or PCI-DSS, is beneficial.
• Knowledge of property-based testing frameworks such as fast-check is a plus.
• Experience optimizing applications for scalability, reliability, and operational excellence is valued.
• Prior experience mentoring engineers or contributing to technical leadership initiatives is advantageous.
• Exposure to modern AI-enhanced engineering workflows and automation practices is beneficial.
• Experience working in autonomous, product-focused engineering teams and a passion for clean architecture and software craftsmanship are highly valued.

Benefits:

• 100% remote work with the flexibility to work from a location that suits you.
• Highly competitive compensation paid in USD.
• Paid time off to support rest, recharge, and work-life balance.
• High level of autonomy and flexibility in managing your time and work.
• Opportunity to work on innovative, high-impact projects with leading U.S. companies.
• Access to a diverse global network of experienced technology professionals.
• Collaboration with senior engineering talent across Latin America and other regions.
• Professional growth through challenging projects, modern technologies, and opportunities for technical leadership.
• A culture focused on well-being, engagement, collaboration, and long-term professional development.
