Description
At Graphwise, we help enterprises transform fragmented data into connected, intelligent systems using Knowledge Graphs, semantic technologies, and modern AI architectures.
About the role
We're looking for a strong Java Backend Engineer who wants to build systems where Knowledge Graphs, LLMs, and custom ML models come together. You'll be designing and implementing backend services that orchestrate complex AI workflows for some of the largest and most prominent organizations in the world. You don't need to be an AI expert already – what matters most is solid engineering thinking, curiosity, and the ability to design clean, reliable systems that solve hard real-world problems.
Main Responsibilities:
Design and build robust backend services that orchestrate Knowledge Graphs, LLMs, and custom ML models
Implement scalable APIs and integration layers that connect AI components with enterprise systems
Develop retrieval and context architectures, including RAG and GraphRAG patterns
Contribute to the design of distributed, production-grade systems for demanding enterprise workloads
Help shape how Knowledge Graphs interplay with modern AI in real-world deployments
Collaborate with ML engineers, data engineers, and solution architects to deliver end-to-end functionality
Collaborate with technical and business stakeholders to solve complex information challenges
Explore and adopt modern AI, NLP, and backend engineering technologies
Must-haves:
Strong software engineering fundamentals
Strong analytical and problem-solving skills
Professional experience with Java and Spring Boot or similar Java backend frameworks
Experience designing and building backend systems, services, and APIs
Solid understanding of good software design practices and distributed systems
Experience with Git, CI/CD, and collaborative engineering practices
Excellent communication skills in English
Curiosity and willingness to learn new domains and technologies
Nice-to-haves:
Cloud platforms, containerization
Experience integrating LLMs or ML models into production backend systems
Familiarity with modern AI concepts such as: LLMs, vector databases, embeddings, (Graph)RAG implementations
