Job Description
Full-Stack Engineer – Java, Next.js
Intetics
• Join a dynamic team to build AI-powered logistics infrastructure platform • Develop and maintain a domain-driven backend and Next.js frontend • Write tests and own architecture decisions with AI handling code generation
Job 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.
