Senior Backend Engineer

Join Jeeves, a fast-growing financial platform, as a Senior Backend Engineer. You will design and build scalable backend systems that process financial transactions and serve customers across 20+ countries. Your responsibilities will include writing clean, production-quality code, building and consuming APIs, optimizing database schemas, and implementing security best practices. You will also collaborate with AI and data science teams, participate in on-call rotation, and contribute to CI/CD pipeline improvements. This is a remote position with flexible work options and comprehensive benefits.

• Design, build, and maintain scalable, reliable backend services that process financial transactions and serve customers across multiple countries.
• Write clean, testable, production-quality code in Go, Python, or Node.js/TypeScript; participate actively in design and code reviews.
• Own backend features end-to-end — from scoping and technical design through deployment, monitoring, and iteration.

• Comfortable using AI tools as part of everyday engineering work — integrating LLM API outputs into backend services and using AI coding assistants fluently
• Fluent in Spanish or Portuguese — preferred for collaboration with LATAM teammates, customers, and operational partners
• Experience in fintech, financial services, payments, or a regulated industry — familiarity with ledger systems, payment rails, or financial compliance (KYC/AML, PCI-DSS) is a strong plus
• Experience designing and building RESTful APIs, microservices, and event-driven backend systems
• Global work experience — prior roles at companies operating across multiple countries and regulatory environments
• Experience with cloud infrastructure (AWS, GCP, or Azure), containerization (Docker, Kubernetes), and CI/CD pipelines
• Fluent in English — professional fluency required for daily work with global teams in written and spoken contexts
• Demonstrated ability to integrate third-party APIs reliably in production — including error handling, retry logic, and observability
• 5+ years of professional backend engineering experience building and operating production systems
• Familiarity with message queue systems (Kafka, RabbitMQ) and event-driven architecture
• Prior experience at a startup or high-growth scale-up, comfortable building in ambiguity without heavy process support
• Experience with multi-currency systems or cross-border payment processing
• Experience working on globally distributed teams across time zones and regions
• Solid understanding of relational databases (PostgreSQL preferred): schema design, query optimization, and data modeling
• Strong proficiency in at least one backend language: Go, Python, or Node.js/TypeScript
