Job Description:

ArkCase is looking for a Senior Java Engineer to join our team and help modernize and scale our enterprise-grade case management platform. You’ll work on challenging engineering problems and modern architecture patterns, contributing to a platform that handles mission-critical workflows for legal, government, and enterprise clients. We’re not looking for someone who’s done everything already, we’re looking for someone who's tackled similarly complex problems and is eager to dig in, solve issues, and deliver robust solutions. You should be self-directed, capable of proposing architecture improvements, and comfortable working without daily handholding. Regular peer reviews and collaborative planning sessions will be your check-ins.

Job Responsibility:

Transition containerized applications from in-pod logging to centralized log aggregation (e.g., syslog)
Significantly reduce Java/Spring application startup time
Refactor synchronous operations (e.g., page counting, file detection) to asynchronous flows
Analyze memory and performance bottlenecks
replace inefficient libraries (e.g., PDFBox)
Identify and modularize monolithic components into microservices (e.g., PDF rendering, audit history, uploads)
Convert our Spring modulith into a distributed service architecture (message or gRPC-based)
Enforce strict plugin architecture with runtime plugin loading
Implement constant-time request handling with async side-effect processing
Enable OAuth and JWT-based authentication to replace Spring Context - based mechanisms
Replace Solr-based metadata querying with SQL-based search
use Solr strictly for full-text search
Introduce multi-tenant persistence capabilities
Enhance build pipeline: enforce formatting, code quality, and security scoring
Lead and support engineering efforts to improve system resiliency
Drive framework and library upgrades (e.g., Java, Spring, Angular)
Improve testing strategy and coverage before undertaking refactors
Contribute to FOIA/legal case file capabilities and ensure future-proof architecture for integrations

Requirements:

Java (core language)
Spring Framework
Kubernetes, managed via Rancher
ActiveMQ (event-based architecture)
Solr (search)
S3 / MinIO (document storage)
Pentaho (reporting)
PDFTron (document viewing & redaction)
Samba (centralized user management)
Node.js / Angular / AngularJS (web UIs)
Keycloak, Splunk, Grafana, Prometheus
Proven experience with complex Java applications and enterprise architecture
Strong knowledge of Spring (modulith/microservices)
Hands-on experience with Kubernetes, containers, and CI/CD pipelines
Comfort with asynchronous processing and event-driven design
Understanding of secure API design and modern authentication (OAuth2, JWT)
Familiarity with performance optimization and memory profiling
Willingness to work with and improve legacy codebases
Strong testing discipline (unit, integration)

Nice to have:

Experience with FOIA or legal case management platforms
PDFTron or other native code integrations
Contributions to microservices design, gRPC, and plugin systems
