Job Description

Java Workflow Engine Developer

Ideal Candidate Profile

The ideal candidate is a strong Java backend engineer who has worked on real enterprise workflow systems, preferably in finance, insurance, banking, or another regulated industry. They understand that workflow applications are not just simple CRUD systems. They require careful handling of process state, transaction boundaries, retries, concurrency, auditability, and production

reliability.

They should be able to design and implement backend workflow services using Java and a workflow engine such as jBPM or Camunda, while also being comfortable using modern AI coding tools to improve productivity.

Position Overview

We are looking for a strong Java Backend Developer / Workflow Engine Developer to design, develop, and support mission-critical, workflow-driven backend applications.

This role requires hands-on experience building enterprise Java services using workflow/BPM engines such as jBPM, Camunda, Flowable, Activiti, or similar platforms. The ideal candidate understands backend transaction integrity, ACID principles, concurrency, multithreading, JVM performance, garbage collection, and enterprise integration patterns. Experience in finance, insurance, banking, government, healthcare, or other workflow-heavy industries is highly preferred, especially where systems require strong auditability, reliability, state management, and transaction correctness.

The candidate should also be comfortable using modern agentic AI development tools such as Claude Code, OpenAI Codex, GitHub Copilot, Cursor, or similar tools to improve productivity, analyze code, generate tests, and accelerate backend development.

Required Qualifications

Strong hands-on experience as a Java backend developer.

Strong experience with Spring Boot, REST APIs, and enterprise backend

service development.

Hands-on experience with at least one workflow/BPM engine, such as:

o jBPM

o Camunda

o Flowable

o Activiti

Apache Airflow, Temporal, or similar workflow orchestration platforms may also be relevant depending on project background.
Strong understanding of workflow-driven application design, including process state, task assignment, escalation, retries, timers, compensation, and audit history.
Solid understanding of ACID transactions, transaction boundaries, rollback behavior, database consistency, and distributed transaction challenges.
Strong knowledge of multithreading, concurrency, thread pools, asynchronous processing, and synchronization issues.

Preferred Qualifications

Experience in finance, insurance, banking, pension, claims processing,
underwriting, payment processing, government case management,
healthcare workflow, or other regulated workflow-heavy domains.
Experience building systems involving approvals, reviews, adjudication, case management, claims, payment workflows, onboarding workflows, compliance workflows, or exception handling.
Experience with BPMN 2.0, DMN, rules engines, or decision tables.
Experience with Camunda 7 / Camunda 8, jBPM, Flowable, or Activiti in production environments.
Experience with message-driven architecture using Kafka, RabbitMQ, JMS,
ActiveMQ, or similar messaging platforms.
Experience with Spring Security, OAuth2, JWT, IAM integration, or role-based access control.
Experience with observability tools such as logs, metrics, traces,
Prometheus, Grafana, ELK, OpenTelemetry, or similar.
Experience with Docker, Kubernetes, CI/CD pipelines, Git, Maven/Gradle, and automated testing.
Experience using GenAI or agentic development tools such as Claude Code,
OpenAI Codex, GitHub Copilot, Cursor, or similar tools.
