We’re seeking a seasoned Senior Data Solution Developer 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.

• Application Development
  • Architect, develop, and maintain backend services using Java (Java 11+/17), Spring (Boot, Data, Security), and RESTful APIs.
  • Implement robust data access patterns using JDBC, JPA/Hibernate, and stored procedures/functions where appropriate.
• Database Engineering
  • Design and optimize schemas, indexes, constraints, and query plans for Oracle Database.
  • Build and maintain ETL/ELT processes; ensure data quality, lineage, auditing, and reconciliation.
  • Implement and query Graph databases (e.g., Tiger Graph, Neo4j, Janus Graph, Amazon Neptune) for relationship heavy workloads; design graph models (nodes, relationships, properties), Cypher/Gremlin queries.
• AI Platform Integration
  • Design and implement AI and Graph DB friendly application data output.
  • Integrate with Graph DB for security graph visualization.
  • Integrate with LLMs and provide solution for complex cybersecurity investigation.
• Performance, Scalability & Reliability
  • Conduct SQL performance tuning (execution plans, hints, statistics, partitioning, indexing strategies).
  • Profile Java services (GC tuning, thread management, connection pools, caching) to meet latency and throughput SLAs.
  • Design for high availability and disaster recovery (replication, failover, backups).
• Security & Compliance
  • Implement least‑privilege access, encryption at rest/in transit, secrets management, auditing, and compliance (SOX/PCI/HIPAA as applicable).
• Collaboration & Leadership
  • Partner with Product, Data, and Platform teams to translate requirements into robust designs.
  • Lead code reviews, establish best practices, and mentor junior engineers.
  • Contribute to roadmaps, estimation, documentation, and production support (on‑call rotation if applicable).

• 8+ 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 (Tiger Graph/Neo4j/Janus Graph/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.
• Strong experience using the MCP to enable LLMs to safely query and interact with cybersecurity data source. Familiarity with secure context management and auditability within MCP‑driven architectures is highly valued.
• Experience with CI/CD, Git, Docker/Kubernetes, and cloud platforms (AWS or Azure).
• Solid understanding of data security, encryption, auditing, and access control.
• Excellent problem‑solving skills, communication, and the ability to lead complex cross‑functional initiatives.

• Experience with data caching (Redis/Apache Ignite), message brokers (Kafka/Rabbit
  
  MQ), and event‑driven architectures.
• Familiarity with partitioning, sharding, table compression, in memory OLTP, and column store indexes (MSSQL).
• Exposure to Oracle features (e.g., AWR/ASH, optimizer hints, partitioning, materialized views).
• Self‑motivated and enjoy resolving issues and building solutions to complex problems.
