Koalafi is a company that provides non-prime financing solutions, allowing more customers to make crucial purchases with convenience and support. By offering lease-to-own and second-look financing options, Koalafi enables retailers to accommodate a wider range of credit scores, helping close the financing gap for up to 47% of U. S. adults who don't qualify for traditional financing. Their services report payment activity to credit bureaus, thus helping customers build credit while making purchases easier and more affordable. Koalafi's data-driven applications ensure quick and confident customer approvals, supporting retailers in increasing conversions and consumer loyalty.

📋 Description

• Implement microservices and event-driven workflows to integrate Koalafi's systems with a third-party loan servicing platform • Build and maintain REST APIs that support loan origination, payment processing, and customer servicing operations • Navigate and contribute to existing internal services where the NPIL product intersects with current Koalafi systems — reading unfamiliar code, understanding its intent, and making clean, well-scoped changes • Develop frontend components in React/TypeScript to support customer-facing and internal tooling as needed • Write code that is testable, observable, and built to last — not just built to ship • Work closely with the Tech Lead on system design and integration architecture • Partner with Product and Compliance to understand requirements and translate them into reliable, compliant implementations • Participate in code reviews — both giving and receiving feedback with the goal of raising the bar, not just checking a box • Engage actively in sprint ceremonies: planning, retros, standups — contribute to the team's rhythm, not just your own ticket • Implement monitoring and alerting at integration points so issues surface before customers notice them • Support audit logging and data reconciliation requirements inherent to a regulated financial product • Identify and flag technical risk early — bad news early is always better than bad news late • Leverage AI development tools to move faster and stay consistent with team patterns

🎯 Requirements

• 2–4 years of professional software engineering experience • Hands-on experience building backend services in Golang • Working knowledge of REST APIs, HTTP/JSON patterns, API authentication including bearer tokens and OAuth flows and API Testing tools like Postman, HTTPPIe • Experience building or contributing to frontend applications; React/TypeScript preferred • Familiarity with AWS, Kubernetes, and cloud-native deployment patterns • Familiarity with observability concepts and tools like Dynatrace • Familiarity with AGILE/Scrum principles, ceremonies and JIRA • Solid testing instincts — unit, integration, and contract testing aren't afterthoughts for you • Comfort navigating and contributing to unfamiliar codebases — not just greenfield builds • Strong communication skills: you can explain what you're building and why, not just how

🏖️ Benefits

• Comprehensive medical, dental, and vision coverage • 20 PTO days + 11 paid holidays • 401(k) retirement with company matching • Student Loan & Tuition Reimbursement • Commuter assistance • Parental leave (maternal + paternal) • Inclusion and Associate Engagement Programs
