Senior Backend Engineer

We are looking for a Senior Backend Engineer with a strong focus on backend architecture, data integrations, and production-ready application development. In this role, you will play a key part in transforming AI-generated prototypes and business workflows into reliable, production-ready applications using our engineering stack. While this is primarily a backend role, you should be comfortable making basic changes to the React/TypeScript frontend when needed to support end-to-end product development.

Responsibilities: - Build and maintain backend applications using Java 21 and Spring Boot, making basic changes to the React/TypeScript frontend when needed. - Convert existing AI-generated and vibe-coded MVPs into reliable, production-ready applications. - Refactor prototype logic into clean backend services, typed APIs, database schemas, and maintainable end-to-end workflows. - Design PostgreSQL schemas and manage database migrations with Liquibase. - Integrate BigQuery as a read source and maintain adjusted/published data views with clear source-of-truth boundaries. - Follow OpenAPI-first development practices to build well-defined APIs and generate typed frontend API clients. - Implement backend observability using Spring Boot Actuator, Prometheus metrics, and structured logging. - Ensure applications are deployable, maintainable, and ready for engineering handoff. - Work with business stakeholders to preserve product intent while improving technical quality.

Requirements

• 5+ years of backend development experience. - Strong proficiency in Java 21 and Spring Boot 3.x. - Strong experience with Maven. - Experience designing and building REST APIs using OpenAPI contract-first development. - Experience with Spring Security. - Strong experience with PostgreSQL schema design and Liquibase. - Experience with BigQuery or similar data warehouse technologies. - Experience with production readiness practices: observability, error handling, configuration, and deployment support. - Solid understanding of versioned data, source-of-truth boundaries, data freshness, cache rebuilds, and fallback behavior. - Experience with AI-assisted development tools (OpenAI, Claude, Cursor, Replit AI, or similar). - Experience evaluating and refactoring AI-generated or vibe-coded solutions into production-ready applications. - Familiarity with React and TypeScript, with the ability to make basic frontend changes when needed. Nice to Have - Experience with multi-module Maven projects. - Experience integrating legacy systems without rewriting them. - Experience with Google APIs (Sheets, Drive, BigQuery). - Experience with n8n or other workflow automation tools. - Familiarity with Vite. - Familiarity with TanStack Query.
