Staff Engineer - JAVA

System Architecture & Design:
Lead the design of cross-functional, enterprise-scale services. You will oversee how Java services interact with No

SQL backends and streaming pipelines to ensure seamless integration.

Technical Strategy:
Partner with Product Management and Dev Ops to define long-term technical debt reduction and infrastructure scaling (Kubernetes/Cloud).

Operational Excellence:
Own the observability strategy. You won't just use Loki or Grafana; you will define the SLIs/SLOs and architectural patterns that ensure 99.9% availability.

Mentorship & Influence:
Act as a force multiplier. Review complex designs, lead "Communities of Practice" for Java performance, and foster a culture of clean code and TDD across multiple teams.

Innovation:
Proactively identify bottlenecks in our Big Data processing (Hadoop/Kafka) or search indexing (Open Search) and spearhead the adoption of new patterns or tools.

Core:
Java (Expert level), Linux (Ubuntu, Rocky Linux).

Data & Streaming:
Cassandra, MongoDB, Hadoop, Kafka.

Search:
Open Search, Lucene.

Infrastructure:
Kubernetes, Docker, Ansible, Jenkins.

Observability:
Prometheus, Grafana, Loki, Zabbix.

15+ years of professional software development experience, with at least 12 years focused on the Java ecosystem.

Architectural Leadership:
Proven experience designing distributed systems that handle massive datasets and high-concurrency workloads.

Deep Networking Knowledge:
Mastery of HTTP/S, TLS, TCP, and Thrift; ability to debug complex network latency or security issues.

Full Lifecycle Ownership:
Experience taking a product from napkin-sketch architecture to global production deployment and long-term maintenance.

JVM Internals:
Expert-level knowledge of JMM (Java Memory Model), Garbage Collection tuning, and multi-threaded synchronization.

Scalability Patterns:
Deep understanding of sharding, consistency models (CAP theorem), and distributed locking.

CI/CD & Dev Ops:
Experience building or significantly optimizing CI/CD pipelines and container orchestration strategies.

Testing Philosophy: A "test-first" mindset that extends beyond Unit Tests to include contract testing, chaos engineering, and performance benchmarking.

Active contributor to open-source Java or Big Data projects.

Experience migrating monolithic legacy systems to modern, service-oriented, or mesh architectures.

Public speaking or technical writing (blogs, whitepapers) on complex engineering topics.
