Full-Stack (Java + Next.js) Engineer

**Intetics Inc**., a global technology company providing custom software application development, distributed professional teams, software product quality assessment, and “all-things-digital” solutions, is seeking a highly skilled and experienced **Full-Stack Engineer** to join our dynamic team on a full-time basis. About the project: Building a neutral, AI-powered logistics infrastructure platform (ZYYDER MESH) connecting shippers and carriers directly - covering quoting, booking, routing, tracking, invoicing, CO₂ reporting, and embedded financial services We're hiring engineers to join the core team building the platform's backbone: an event-driven, domain-driven backend with a Next.js frontend. This is not a "write code from a ticket" role. Development is AI-driven - engineers write tests and own architecture decisions; AI handles code generation in between, with the engineer as the human-in-the-loop reviewer. **Architecture & design patterns** (this is the primary screen — technical stack comes second): - Domain-Driven Design (DDD) — bounded contexts, aggregates, aggregate roots, value objects, domain events, ubiquitous language - Hexagonal architecture (ports & adapters) - CQRS (command/query responsibility segregation) - Saga pattern (distributed transaction coordination) - Outbox pattern (reliable event delivery) - Event sourcing and eventual consistency at scale - Designing for high throughput, strong and eventual consistency **Backend:** - Java (core language) - Kafka (event streaming) - PostgreSQL - Redis - Blob storage / S3 - Parquet, Delta files - Serialization: Protobuf, Avro, JSON - gRPC, REST - CDC (Change Data Capture) via Debezium **Frontend:** - Next.js (backend-for-frontend pattern) - JavaScript, TypeScript - MUI (Material UI) - Figma (design handoff) - REST, JSON, Protobuf, gRPC integration from the frontend - PostgreSQL (read-side familiarity) **What we're explicitly NOT looking for** - Engineers who know the tech stack but have never applied DDD/CQRS/Saga/Hexagonal patterns in production - Candidates needing onboarding time to learn these concepts — there isn't time before the September start - Pure backend or pure frontend specialists without full-stack range across this stack
