Job description

At Lumenalta, we partner with forward‑thinking organizations to build technology solutions that scale, delight users, and accelerate business growth. We value transparency, autonomy, and impact, empowering every team member to do their best work.

We’re seeking a BRMS / Drools Developer with strong Java expertise to design and implement complex business‑rule solutions for enterprise‑scale systems. This role is ideal for someone who thrives on translating business logic into elegant, maintainable rules and integrating them seamlessly into modern Java applications.

Salary range: $60,000 – $96,000 annually, with final compensation determined by your qualifications, expertise, experience, and the role's scope.

What You’ll Do

• Design, develop, and optimize business rules using the Drools Rule Engine, integrating these rules into Java / Spring Boot enterprise applications.
• Develop and implement Decision Model and Notation (DMN) models and complex event processing (CEP) features using Drools Fusion.
• Build and maintain microservice architectures, ensuring seamless integration of rule‑based services.
• Containerize and deploy Drools applications using Docker and manage them in AWS cloud environments.
• Configure, tune, and maintain application servers such as WildFly (JBoss AS) and Tomcat.
• Collaborate with cross‑functional teams, including Business Analysts and Product Managers, to translate complex business logic into executable rules.
• Implement and maintain automated test suites to validate rule execution and ensure system stability.
• Monitor, optimize, and continuously improve rule performance and scalability.

Required Skills & Qualifications

• Bachelor’s degree in Computer Science, Information Technology, or related field.
• 7+ years of experience in Java development with a strong focus on the Drools Rule Engine.
• Hands‑on experience with Drools Workbench, KIE Execution Server, and KIE APIs.
• Expertise in Java, Spring Boot, and microservices architecture.
• Experience with containerization (Docker) and cloud platforms, preferably AWS.
• Strong understanding of rule‑based systems, decision tables, and rule optimization techniques.
• Familiarity with Agile methodologies and test automation frameworks (JUnit, TestNG, Cucumber).

Nice to Have

• Experience with Red Hat Decision Manager (RHDM) or other enterprise BRMS tools.
• Knowledge of CI/CD pipelines (Jenkins, GitHub Actions) and infrastructure as code.
• Exposure to performance tuning, rule versioning, and governance in production environments.
• Familiarity with API integration and REST‑based decision services.

This position is open to candidates based in the United States only. Applicants must have current U.S. work authorization.

Location: This is a fully remote position; however, candidates must be based in regions that align with the Pacific, Central, or Eastern U.S. time zones to ensure effective collaboration with client and team schedules.

In addition to competitive pay, we offer a variety of benefits to support your professional and personal growth, including:

• Flexible working hours in a remote environment.
• Health insurance (medical and dental) for W2 employees.
• 401K contribution.
• A professional development fund to enhance your skills and knowledge.
• 15 days of paid time off annually.
• Access to soft‑skill development courses to further your career.

This is a full‑time position requiring a minimum of 40 hours per week, Monday through Friday.
