Today we have more than 9 million active users, both consumers and merchants, and we've become a trusted brand in Venezuela, winning hearts and minds.\nAbout the role\nWe're looking for a Senior Backend Engineer who owns systems, not just services. You'll design the backend that moves money for millions of people - which means correctness, resilience, and performance aren't nice-to-haves, they're the job.\nYou'll work close to Product and to other engineering teams, shaping how our platform scales as we grow. This is hands-on: you'll write code, make architectural calls, and be on the hook for how your services behave in production. The growth path here rewards engineers who go deep, raise the bar around them, and make the system better than they found it.\nOverall you will...\nDesign and build robust, scalable backend services in Node.js and NestJS (Express).\n\nCreate and maintain high-performance RESTful APIs that other teams can build on with confidence.\n\nBuild for financial correctness - idempotency, reconciliation, retries, and well-defined failure states.\n\nModel and manage relational data, primarily in PostgreSQL, with performance and integrity in mind.\n\nMake architectural and system-design decisions, and own the trade-offs behind them.\n\nEnsure optimal service performance and own production deployments end-to-end.\n\nRaise the engineering bar through code reviews, pairing, and clear technical standards.\n\nMentor engineers and lead technical discussions, leaving the team stronger than you found it.\n\nMove fast across multiple workstreams in a dynamic, high-growth startup environment.\n\nQualifications\nBachelor's degree in Computer Science or a related field, or equivalent practical experience.\n\n5+ years of backend development experience, with solid depth in Node.js and NestJS (Express).\n\nProven experience designing and operating RESTful APIs in production.\n\nAdvanced knowledge of relational databases, preferably PostgreSQL.\n\nExperience writing unit and integration tests, and treating quality as part of delivery.\n\nStrong grasp of design principles and architectural patterns.\n\nTrack record of shipping features independently and owning service performance in a fast-moving context.\n\nAbility to communicate complex technical concepts clearly, and to mentor others effectively.\n\nExcellent problem-solving and analytical thinking, with genuine curiosity about new technology.\n\nDesirable skills\nExperience with cloud platforms, specifically Google Cloud Platform (GCP).\n\nKnowledge of containers and orchestration, such as Docker and Kubernetes.\n\nExperience with messaging and queuing systems like RabbitMQ, Kafka, or Pub/Sub.\n\nExperience building in fintech, payments, or credit.\n\nSpanish and English proficiency.\n\nInterview Process\nSilver screening Interview\n\nSilver Technical Interview (System Design Interview)\n\nClient Screening Interview\n\nClient Technical interview\n\nClient Behavioral
