The posting

We are seeking a Senior Drools Engineer to design, build, and maintain business rules for a large‑scale underwriting and decisioning platform. This role focuses on translating complex credit and risk policies into high‑performance, explainable Drools rules that power real‑time decisions.

Key Responsibilities

• Design, develop, and maintain Drools (KIE) rules using DRL, Decision Tables, and Rule Templates to implement complex underwriting, eligibility, and policy logic

• Optimize rule execution for low latency and high throughput, including management of rule salience, agenda groups, rule flows, and conflict resolution

• Ensure decisions are deterministic, explainable, and auditable, meeting regulatory and audit requirements

• Contribute to the overall decisioning and rules architecture, designing rule sets for reusability, versioning, and controlled rollout

• Participate in design reviews and technical discussions related to rule design and platform evolution

• Develop unit tests and scenario‑based tests to validate rule behavior across multiple decision paths

• Troubleshoot production issues related to rule execution and support deployments across development, QA, and production environments

• Act as a subject‑matter expert for Drools and business rules best practices, mentoring junior engineers

• Establish and enforce standards for rule authoring, documentation, testing, and maintainability

Required Qualifications

• 7+ years of software engineering experience

• 5+ years hands‑on experience with Drools / KIE

• Strong proficiency in Java

• Experience in building a lightweight orchestration layer using Apache Pekko is a plus

• Deep experience with:

◦ DRL, Decision Tables, Rule Templates

◦ Stateless and stateful KIE sessions

◦ Rule performance tuning and debugging

◦ Experience building or supporting policy‑driven or decisioning systems

◦ Strong understanding of business rules management systems (BRMS)

◦ Exposure to cloud platforms and CI/CD pipelines

What Success Looks Like

• Business policies are accurately captured as maintainable Drools rules

• Decisions are fast, consistent, and explainable

• Rule changes can be made confidently without impacting platform stability

• The rules layer is reliable, scalable, and regulator‑ready

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
