About this role.
This Senior Full-Stack Engineer role supports a tech-driven real estate company on fintech-focused, high-transaction systems. The engineer will own features end to end, spanning PostgreSQL data modeling, Node.js and TypeScript backend services, event-driven integrations, and React/Next.js interfaces. Core work emphasizes reliability patterns such as idempotency, retry handling, dead-letter queues, outbox workflows, reconciliation, observability, and secure handling of sensitive financial data. The position is fully remote for LATAM talent and expects autonomous collaboration, technical leadership, mentoring, and use of AI-assisted development tools.

Sample interview questions
I would persist each provider event with a unique idempotency key and process it within a transaction where appropriate. The consumer would acknowledge only after durable state changes succeed, use retries with exponential backoff for transient failures, and route exhausted failures to a DLQ. I would also build reconciliation jobs to compare internal records with the provider's source of truth.
I would use an outbox pattern when a database update and event publication must remain consistent without relying on distributed transactions. The application writes both the business change and an outbox record in one database transaction; a separate publisher reliably emits the event and marks it delivered. This prevents a successful data update from being lost if the message broker is temporarily unavailable.
I start by measuring the slow query and reviewing EXPLAIN ANALYZE, row estimates, join strategy, index usage, lock behavior, and I/O. I then improve query shape, add or adjust targeted indexes, avoid unnecessary data retrieval, and validate changes against representative production-like data. For transactional workloads, I also assess isolation level, contention, and connection-pool behavior.
I would define clear API contracts and model the UI around explicit states such as queued, processing, completed, and failed. The frontend should provide immediate feedback, safely poll or subscribe for status updates where needed, and expose actionable error handling without implying that an asynchronous operation has completed prematurely. I would keep domain logic on the server and use reusable UI components for consistent loading and error states.
I would add structured logs, metrics, and distributed traces with a correlation ID propagated across requests, queue messages, and third-party calls. Key metrics would include throughput, latency, retry volume, DLQ depth, reconciliation mismatches, error rate, and success rate by provider. Alerts should focus on customer-impacting thresholds and be paired with dashboards and runbooks for rapid incident response.
