About The Position

Appian is seeking a Senior Software Engineer to join their team. This role involves designing and building features end-to-end for the analytics layer of the Appian platform, which is used by millions of business users. The work spans from database schema design to chart components and AI prompt pipelines. The engineer will work across a multi-language, full-stack environment, shaping how enterprise users discover insights from their data. This includes designing and building features from schema migrations and Spring/Hibernate service layers, through Java and SAIL (proprietary functional UI language) with Redux state management, to TypeScript/React chart components. On the AI side, the role involves extending 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.

Requirements

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

Nice To Haves

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

Responsibilities

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
