Principal Backend Engineer

This is a fully remote position, open to applicants in Mexico.

📋 Description

• Design, develop, and maintain scalable and reliable backend services that process financial transactions for Jeeves customers in over 20 countries.

• Write clean, testable, production-quality code using Go, Python, or Node.js/TypeScript; actively engage in design and code reviews.

• Create and utilize RESTful and GraphQL APIs; design inter-service communication with gRPC, message queues, and event-driven architectures.

• Design and optimize relational and non-relational database schemas (PostgreSQL, MongoDB, Redis) ensuring correctness, performance, and scalability.

• Take ownership of backend features throughout the entire lifecycle — from scoping and technical design to deployment, monitoring, and iteration.

• Implement best practices for security: authentication, authorization, input validation, and data protection across distributed services.

• Integrate LLM API calls (e.g., OpenAI, Anthropic) into backend services as product features — such as spend categorization, document parsing, or natural language workflows — ensuring these integrations are reliable, observable, and cost-effective.

• Develop backend pipelines that safely consume AI-generated outputs: validating structured outputs, managing fallback scenarios, and designing for graceful degradation when AI services are unavailable or yield low-confidence results.

• Collaborate with AI and data science teams to merge model outputs into backend APIs — linking experimental AI efforts with production systems.

• Utilize AI coding tools (GitHub Copilot, Claude, Cursor, etc.) proficiently as part of your daily development workflow.

• Instrument services with structured logging, distributed tracing, and metrics to achieve full operational visibility.

• Participate in on-call rotations; address production incidents and contribute to post-incident reviews.

• Contribute to improvements in CI/CD pipelines, testing infrastructure, and deployment practices.

• Work collaboratively with engineering, product, compliance, and data teams across various time zones and regions — communicating in both English and Spanish or Portuguese as needed.

• Foster a globally distributed engineering culture through comprehensive documentation, asynchronous design reviews, and constructive pull request feedback.

• Bring your regional insights to product and engineering discussions — understanding the specific needs of our LATAM customers enhances our product.

⛳️ Requirements

• 5+ years of professional backend engineering experience in building and operating production systems.

• Fluent in English — professional proficiency is necessary for daily communication with global teams in both written and spoken contexts.

• Fluent in Spanish or Portuguese — essential for collaboration with LATAM teammates, customers, and operational partners.

• Strong expertise in at least one backend programming language: Go, Python, or Node.js/TypeScript.

• Experienced in designing and constructing RESTful APIs, microservices, and event-driven backend systems.

• Solid comprehension of relational databases (PostgreSQL preferred): schema design, query optimization, and data modeling.

• Familiarity with cloud infrastructure (AWS, GCP, or Azure), containerization (Docker, Kubernetes), and CI/CD pipelines.

• Proven ability to integrate third-party APIs reliably into production — encompassing error handling, retry logic, and observability.

• Experience working with globally distributed teams across different time zones and regions.

• Comfortable incorporating AI tools into daily engineering tasks — integrating LLM API outputs into backend services and using AI coding assistants effectively.
