About Perseus Payments Inc.

Perseus Payments Inc., part of Constellation Software, builds PerseusPay. PerseusPay is a cloud-native payments platform for marine, outdoor power equipment and RV dealers in the US and Canada. The platform is PCI DSS compliant, and the team is building toward an AI-native way of developing software.

Why This Role

This is a chance to build features on a live payments platform used by hundreds of dealer locations. You will own work from an incomplete brief through to production, across backend, UI and payment processor integrations. The platform is secure, PCI-compliant and built to scale.

Role Overview

We are hiring a software developer for the team that builds new PerseusPay features, as distinct from our support and platform work. You will own features from an incomplete brief through to production: shaping the design, building the backend APIs and UI, working through payment-processor rules, and shipping behind feature flags. Requirements on a payments product change often, because processor behaviour, compliance rules, DMS partner needs and dealer feedback all move. We want someone who finds that interesting and keeps delivering without waiting to be told what to do next.

Key Responsibilities

• Take a feature from PRD or user story to production: clarify the scope, design the solution, build, test, and release behind a feature flag.

• Build and maintain REST APIs, background processing and database changes in C# / .NET.

• Build and maintain React UI for the dealer portal, the embedded payment page and the checkout plugin.

• Integrate with payment processor APIs and webhooks, and read processor documentation to find the edge cases that matter.
