We are looking for a Senior/Lead Full-Stack Engineer with a strong backend and product-integration focus, who will also play a key role in shaping engineering standards and development practices across the team.
This person will take ownership of turning business workflows and early MVPs into reliable, production-ready applications — and will establish the patterns and guidelines others follow, using our agreed engineering stack.
Main Responsibilities
Define and maintain engineering standards, development guidelines, and code quality practices for the team
Lead architecture decisions for the Internal Operational Platform and connected tooling
Build and maintain full-stack applications using Java/Spring Boot and React/TypeScript
Convert existing vibe-coded MVPs into production-ready implementations
Refactor prototype logic into clean backend services, typed APIs, database schemas, and maintainable frontend workflows
Design PostgreSQL schemas and Liquibase migrations
Integrate BigQuery reads and adjusted publish layer
Follow and enforce OpenAPI-first development and typed frontend API clients
Own backend observability through Actuator, Prometheus metrics, and structured logs
Ensure apps are deployable, maintainable, and ready for engineering handoff
Work with business stakeholders to preserve product intent while raising technical quality

Java 21
Spring Boot 3.x
Maven

Strong preference:

Experience defining backend architecture standards and code review practices
Frontend

TanStack Query or equivalent server-state management
Strong handling of loading/error/empty states
Ability to build practical workflow UIs, not just static pages

Ability to reason about data freshness, cache rebuilds, and fallback behavior
Nice-to-have:
Google APIs: Sheets, Drive, BigQuery

Must-have:
Hands-on experience with AI-assisted development and LLM integrations, including tools and APIs such as OpenAI, Claude/Anthropic, Cursor, Replit AI, or similar
