Required Skills & Experience
- 10+ years of professional software development experience, with 5+ years focused on Java backend development.
- Expert-level SQL and RDBMS experience with Oracle (schema design, complex queries, query optimization, stored procedures, PL/SQL/T-SQL).
- Hands-on experience with Graph databases (TigerGraph/Neo4j/JanusGraph/Amazon Neptune), including data modeling and query languages (Cypher, Gremlin).
- Strong experience with Java 11+, Spring Boot, REST APIs, JPA/Hibernate, and JDBC.
- Proven track record in performance tuning (both SQL and JVM), transactions, locking, isolation levels, and concurrency.

Job Description
We’re seeking a seasoned Senior Java Developer/AI Engineer to design, build, and optimize mission critical applications and data platforms. You will own end to end engineering across backend services (Java/Spring) and data layers with a focus on performance, reliability, security, and scalability. Additionally, you will be responsible for integrating with industry leading AI platforms for cybersecurity intelligence solution. This is a hands-on role for someone who enjoys solving complex data and system problems, leading technical initiatives, and mentoring others.
Key Responsibilities
- Application Development o Architect, develop, and maintain backend services using Java (Java 11+/17), Spring (Boot, Data, Security), and RESTful APIs. o Implement robust data access patterns using JDBC, JPA/Hibernate, and stored procedures/functions where appropriate.
- Database Engineering o Design and optimize schemas, indexes, constraints, and query plans for Oracle Database o Build and maintain ETL/ELT processes; ensure data quality, lineage, auditing, and reconciliation. o Implement and query Graph databases (e.g., TigerGraph, Neo4j, JanusGraph, Amazon Neptune) for relationship heavy workloads; design graph models (nodes, relationships, properties), Cypher/Gremlin queries.
- AI Platform Integration o Design and implement AI and Graph DB friendly application data output o Integrate with Graph DB for security graph visualization o Integrate with LLMs and provide solution for complex cybersecurity investigation
- Performance, Scalability & Reliability o Conduct SQL performance tuning (execution plans, hints, statistics, partitioning, indexing strategies). o Profile Java services (GC tuning, thread management, connection pools, caching) to meet latency and throughput SLAs. o Design for high availability and disaster recovery (replication, failover, backups).
- Security & Compliance o Implement least-privilege access, encryption at rest/in transit, secrets management, auditing, and compliance (SOX/PCI/HIPAA as applicable).
- Collaboration & Leadership o Partner with Product, Data, and Platform teams to translate requirements into robust designs. o Lead code reviews, establish best practices, and mentor junior engineers. o Contribute to roadmaps, estimation, documentation, and production support (on-call rotation if applicable).
