JAVA FULL-STACK DEVELOPER (Java
· Spring Boot
· Kafka (distributed systems) ?

Location:
T-Hub, Hyderabad (On-site) ?

Experience:
4–7 years of professional Java backend development ?️ Work Week: 6 days for the first 9 months → 5 days after ? Type: Full-time ? Company: QUIPU (https://thequipu.com/) ━━━━━━━━━━━━━━━━━━━━ ABOUT QUIPU Quipu is AI infrastructure for long-term memory. We give every entity in a complex system a single, audit-grade memory so engineering teams can study cause and effect instead of guessing at it. Our platform powers real enterprise work:
- Vehicles with component-level traceability and failure prediction
- Drug development with fewer risky experiments
- Battery storage systems with trusted cell-ageing models
- AI agents with a shared persona that never resets ━━━━━━━━━━━━━━━━━━━━ ⚠️ PLEASE READ BEFORE APPLYING This is an on-site role at T-Hub, Hyderabad, on a 6-day working week for the first 9 months. We're building core infrastructure on a hard timeline and would rather be upfront about the commitment than surprise you later. After 9 months, the schedule moves to a standard 5-day week. Applications with less than 3 years of skilled Java experience will not be considered. ━━━━━━━━━━━━━━━━━━━━ THE ROLE We're looking for a Java backend engineer who thinks in systems, not just code. You'll own architecture decisions on the core services behind a distributed graph memory platform: graph storage, streaming ingestion, ETL pipelines and semantic retrieval at scale. We expect you to reason about trade-offs and failure modes before you write a line of code. ━━━━━━━━━━━━━━━━━━━━





WHAT YOU'LL DO
- Build and evolve Spring Boot microservices at the core of the platform
- Own architecture decisions: service boundaries, data flow, failure handling and how the platform scales
- Design security and access control: authentication, authorization, multi-tenant data isolation and secrets management
- Build event-driven, Kafka-based pipelines with backpressure-aware stream processing and actor-model concurrency
- Build and operate ETL and ingestion workflows across heterogeneous data sources
- Model and query data across graph (Neo4j), distributed SQL (YugabyteDB), vector stores and embedded key-value stores
- Own features end-to-end: design, build, test, deploy and debug in production using logs, metrics and traces
- Take part in design reviews and explain your decisions with clear reasoning ━━━━━━━━━━━━━━━━━━━━ MUST-HAVE ✅ 4–7 years of production experience with Java and Spring Boot ✅ Strong core Java: collections, concurrency, JVM fundamentals ✅ Experience designing service boundaries and owning systems beyond single features ✅ Security in Java apps: OAuth2/OIDC, JWT, role
- and attribute-based access control, secure API design ✅ Production experience with Kafka or a similar event-streaming platform ✅ Experience building or operating ETL / data pipelines ✅ Distributed systems fundamentals:



consistency, partitioning, idempotency, retries, backpressure, failure handling ✅ Strong SQL plus experience with at least one NoSQL or graph database ✅ Available on-site in Hyderabad, 6 days a week for the first 9 months ━━━━━━━━━━━━━━━━━━━━ STRONG PLUS ⭐ Keycloak, HashiCorp Vault or production IAM integration ⭐ Akka / Apache Pekko (actors, streams, cluster) ⭐ Neo4j, Cypher or graph data modeling ⭐ Distributed SQL (YugabyteDB, CockroachDB, Spanner-class systems) ⭐ Vector databases and semantic search (Milvus, pgvector, etc.) ⭐ Python (FastAPI) for service sidecars ⭐ LLM-integrated systems: prompt pipelines, extraction workflows, RAG ⭐ Jenkins, Docker, containerized deployments on Linux ━━━━━━━━━━━━━━━━━━━━ WHO YOU ARE
- You ask "Why is the system shaped this way?" before "What do I build?"
- You're comfortable with ambiguity and small-team ownership, without rigid specs or hand-holding
- You debug from first principles and write down what you learn
- You communicate trade-offs clearly and disagree constructively ━━━━━━━━━━━━━━━━━━━━

WHAT WE OFFER
?Designation: Member Technical Staff ? Direct ownership of core infrastructure: your work ships and matters immediately ? Deep, unusual problems: bitemporal modeling, graph traversal at scale, streaming knowledge extraction ? Close mentorship from technical leadership on architecture and systems design ?
