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

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

Experience: 4–7 years of qualified 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 professional 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

A small, high-ownership team building infrastructure for enterprise clients
