At BrightWay (www.meetbrightway.com) we’re living our mission to improve the financial well-being of hard-working Americans. Our goal is to transform the way our customers think about and use credit cards, rewarding good behavior in ways that truly add value, while providing experiences that empower and engage, even if that means challenging industry norms.

Operating as a startup and owned by OneMain Financial, one of the largest and most successful personal finance companies in the industry, we launched our digital-first suite of credit cards in 2021 and have been on a high growth, fast-track ride of fostering innovative thinking to engaging and empower our customers ever since. We continually challenge what a digital finance product can be - employing a customer-first approach in developing all of our products, features, or experiences. We’re not afraid to look to outside influences and create new frameworks.

We are seeking a Senior Staff level Software Engineer with extensive Drools experience 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

Basic Qualifications:

  • 7+ years of software engineering experience

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

  • Strong proficiency in Java and Spring/Spring Boot

  • Deep experience with:

  • Experience with DRL, Decision Tables, Rule Templates

  • Experience with stateless and stateful KIE sessions

  • Experience with 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

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

  • Experience with building solution on Python, Javascript, NodeJs is a plus
