[Hiring] Software Architect (Backend, Node.js) @EX Squared LATAM

Role Description

Become an EXpert as a Software Architect (Backend, Node.js) at EX Squared LATAM, where we partner with leading U.S.-based technology companies to build scalable, high-performance systems that power real-world business operations.

We are currently looking for a Software Architect (Backend, Node.js) to join a fast-growing healthtech company. This is a high-impact, hands-on architecture role within a small team, focused on designing and evolving distributed, real-time, cloud-native systems that operate at scale.

This role goes beyond implementation, we are specifically seeking individuals who have designed and built event-driven systems end-to-end and have successfully navigated real-world production challenges, including failure scenarios, system degradation, and recovery strategies.

What You'll Do

• Architect, design, and lead the development of scalable backend systems using Node.js and TypeScript.
• Define and implement robust event-driven architectures, including asynchronous workflows and messaging patterns (e.g., queues, streams).
• Drive the design of fault-tolerant, resilient distributed systems, including clear strategies for:
  • Error handling
  • Failure recovery
  • Retry mechanisms
  • Idempotency and consistency
• Lead the evolution of microservices architectures running in AWS production environments.
• Establish and improve system reliability, observability, and monitoring practices.
• Guide teams on best practices in scalability, performance optimization, and system design.
• Contribute to and elevate CI/CD pipelines and Infrastructure as Code (Terraform, CloudFormation, etc.).
• Act as a technical leader in architectural decisions, mentoring engineers and reviewing system designs.
• Collaborate cross-functionally while maintaining a strong backend and platform focus.
• Remain hands-on when needed, delivering production-grade code and solutions.

Qualifications

• 10+ years of software engineering experience, with a strong backend focus.
• Proven experience architecting and building distributed, real-time systems in production.
• Deep, hands-on experience with event-driven architectures, beyond basic usage:
• Demonstrated ownership of system design decisions.
• Experience handling real-world failure scenarios at scale.
• Strong expertise in Node.js, JavaScript, and TypeScript.
• Extensive experience with AWS in production environments.
• Solid background in microservices architecture and system decomposition.
• Proven ability to design systems with high availability, fault tolerance, and resilience.
• Experience implementing observability, monitoring, and alerting strategies.
• Strong understanding of CI/CD pipelines and Infrastructure as Code.
• Ability to evaluate trade-offs and deliver robust, production-ready solutions, not just functional ones.
• Advanced English proficiency for technical leadership and communication.

Nice to Have

• Experience with streaming platforms (Kafka, Kinesis, etc.).
• Experience with multi-region or globally distributed systems.
• Exposure to healthcare or regulated environments.
• Experience with Python or polyglot backend systems.
• Frontend collaboration experience (React or similar).
• Background in startups or high-growth environments.

What We're Prioritizing

• Candidates who have built and owned complex event-driven systems, not just used them.
• Strong experience dealing with system failures, edge cases, and recovery mechanisms.
• Engineers with breadth and depth across the stack and lifecycle of distributed systems.
• Profiles with solid industry experience (~10+ years) to ensure well-rounded architectural judgment.

Benefits

• You will join a collaborative LATAM engineering team working on systems that directly impact patient care in the U.S. healthcare industry.
• This is an opportunity to contribute meaningfully to backend platform evolution while remaining deeply hands-on in development.
