Lead/Staff Full-Stack Engineer

AI Digital is an AI-native media consultancy and innovation partner powered by an Open Garden framework. Founded in 2018, AI Digital’s global team of 550+ specialists connects clients to audiences through a unique blend of human expertise and advanced technology, delivering unbiased, AI-enhanced media solutions for brands and agencies. The company partners with all major advertising platforms to deliver measurable results aligned with clients’ business objectives and brand KPIs.
We are looking for a Lead/Staff 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.
What You'll Do:
Lead architecture decisions for our Internal Operational Platform and connected tooling, and define the engineering standards and code quality practices the team follows.
Build and maintain full-stack applications (Java/Spring Boot + React/TypeScript), turning vibe-coded MVPs and prototypes into clean, production-ready services with typed APIs, proper auth, 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 (Actuator, Prometheus, structured logs).
Partner with business stakeholders to preserve product intent while raising technical quality.
You Are a Great Fit If:
Backend: Java 21, Spring Boot 3.x, REST/OpenAPI contract-first development, PostgreSQL + Liquibase, Spring Security, and observability tooling (Actuator, Prometheus). Bonus if you've defined backend architecture standards, worked in multi-module Maven projects, or integrated legacy systems without rewriting them.
Frontend: React + TypeScript, API-driven UI, server-state management (e.g. TanStack Query), and a good instinct for loading/error/empty states and practical workflow UIs.
Data & Integration: Experience with BigQuery or a similar warehouse, and comfort reasoning about versioned data, source-of-truth boundaries, freshness, and cache/fallback behavior. Nice to have: Google APIs (Sheets, Drive, BigQuery), workflow automation tools like n8n.
AI-Assisted Development: Hands-on experience building with LLM tools and APIs (OpenAI, Claude/Anthropic, Cursor, Replit AI, or similar), and the judgment to evaluate, refactor, and productionize AI-generated code into a clean, maintainable stack.
What We Offer:
Salary that values your expertise.
31 days of paid time off – 21 days of annual leave + 10 days sick leave, because balance matters.
Growth-focused environment – access to learning resources and clear pathways for advancement.
Fun team events – join our online cooking classes, yoga sessions, and more – all from home!
A Culture of Trust – say goodbye to bureaucracy and micromanagement; we focus on results, not processes.
