Senior Software Engineer - Java / Hibernate

We're looking for a Senior Software Engineer who thrives in a multi-language, full-stack environment and wants to shape how enterprise users discover insights from their data. You'll design and build features end-to-end: from schema migrations and Spring/Hibernate service layers, through Java and SAIL (our proprietary functional UI language) with Redux state management, to TypeScript/React chart components.

On the AI side, you'll extend our LLM copilot infrastructure, building prompt pipelines, validation actions, and suggestion services that use large language models to generate KPIs, insight summaries, and event recommendations from process mining data.

What You'll Do:

• Design and implement full-stack features across Java services, SAIL interfaces, and React/TypeScript chart components
• Build and extend AI copilot pipelines that use LLMs to generate process insights, KPI suggestions, and actionable recommendations
• Own features from database schema (Liquibase/JPA) through API layer (Spring) to interactive UI
• Develop rich data visualization experiences: chart configuration UIs, dashboard builders, and report designers
• Write interface-first Java with constructor injection and proper layering
• Contribute to SAIL system rules using functional programming patterns, Redux state management, and deferred evaluation
• Build and maintain TypeScript/React chart widgets that render complex configurations
• Lead feature development with spec-driven workflows, mentor engineers, and conduct thorough code reviews
• Ensure reliability through comprehensive testing (unit expression tests, integration tests, UI tests, migration tests)
• Collaborate on feature breakdowns, sizing, and architectural decisions with your squad

Required:

• BS in Computer Science (4+ years experience) or MS in Computer Science (2+ years experience)
• Strong Java fundamentals - Spring Framework, Hibernate/JPA, interface-first architecture, dependency injection
• Experience building interactive web UIs with TypeScript/React (or similar component frameworks)
• Comfort with functional programming concepts (immutability, higher-order functions, declarative UI)
• Experience with relational databases - schema design, migrations, query optimization
• Demonstrated ability to work across multiple languages and layers in a single feature
• Strong testing discipline - unit, integration, and UI-level tests
• Excellent communication skills and ability to mentor others

Preferred:

• Experience with data visualization libraries (Highcharts, D3, Chart.js, or similar)
• Experience integrating LLMs/AI into production features (prompt engineering, pipeline design, response validation)
• Familiarity with Redux or similar state management patterns
• Experience with Gradle build systems and CI/CD pipelines
• Background in analytics, reporting, or business intelligence tooling
• Experience with process mining or operational intelligence
