Full-Stack (Java + Next.js) Fejlesztő

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 Originally posted on Himalayas
