Principal Backend Engineer

Design, build, and maintain scalable, reliable backend services that process financial transactions and serve Jeeves customers across 20+ countries.

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

Build and consume RESTful and GraphQL APIs; design inter-service communication using gRPC, message queues, and event-driven architectures.

Design and optimize relational and non-relational database schemas (PostgreSQL, MongoDB, Redis) for correctness, performance, and scale.

Own backend features end-to-end — from scoping and technical design through deployment, monitoring, and iteration.

Implement security best practices: 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 those integrations are reliable, observable, and cost-efficient.

Build backend pipelines that consume AI-generated outputs safely: validate structured outputs, handle fallback scenarios, and design graceful degradation when AI services are unavailable or return low-confidence results.

Collaborate with AI and data science teams to integrate model outputs into backend APIs — bridging experimental AI work and production systems.

Use AI coding tools (GitHub Copilot, Claude, Cursor, etc.) fluently as part of your everyday development workflow.

Instrument services with structured logging, distributed tracing, and metrics for full operational visibility.

Participate in on-call rotation; respond to production incidents and contribute to post-incident reviews.

Contribute to CI/CD pipeline improvements, testing infrastructure, and deployment practices.

Work closely with engineering, product, compliance, and data teams across multiple time zones and regions — communicating in both English and Spanish or Portuguese as the situation requires.
