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.

Requirements

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
