Lead Full-Stack Engineer

About the role

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.

Key responsibilities

• Lead architecture decisions for our Internal Operational Platform and connected tooling, defining engineering standards and code‑quality practices.
• Build and maintain full‑stack applications (Java/Spring Boot + React/TypeScript), turning prototypes into clean, production‑ready services with typed APIs, proper authentication, persistence, and observability.
• Design PostgreSQL schemas and Liquibase migrations, and integrate BigQuery reads and publish layers.
• Champion OpenAPI‑first development and typed frontend API clients.
• Own backend observability using Actuator, Prometheus, and structured logs.
• Partner with business stakeholders to preserve product intent while raising technical quality.

Required profile

• Strong backend expertise with Java 21, Spring Boot 3.x, REST/OpenAPI, PostgreSQL, Liquibase, Spring Security, and observability tooling.
• Proficient frontend development with React, TypeScript, API‑driven UI, and state‑management libraries such as TanStack Query.
• Experience with data integration, BigQuery or similar warehouses, and handling versioned data, freshness, and cache/fallback strategies.
• Hands‑on experience building with LLM tools and APIs (OpenAI, Claude/Anthropic, Cursor, Replit AI) and refactoring AI‑generated code into a maintainable stack.
