Software Developer- Fullstack

Join our PBU Subscriptions team, where you'll build backend services that power recurring loyalty subscriptions for global travel partners. Our subscription platform owns the subscription lifecycle, product catalogue, recurring billing engine, payment integrations, and member-facing workflows. We’re looking for a backend developer who wants to own meaningful product capabilities end to end - not just clear tickets.

You’ll help evolve our Python/Flask services and Cloudant-backed systems, improve observability and production support, and use AI-assisted workflows to accelerate coding and testing without compromising quality. You’ll contribute to technical proposals, help lead initiatives as an Epic Champion, and troubleshoot high-impact production issues as part of the team’s shared support rotation.

Python 3.11

You build maintainable backend systems and robust APIs, with clean code, strong computer science fundamentals, and the ability to reason about complex stateful workflows, data models, and recurring billing logic.

You hold a high standard for software quality, using unit and integration testing, static analysis, and CI/CD feedback loops to ship reliable features quickly and safely.

You communicate complex technical concepts clearly, making architecture and trade-offs accessible to product, design, QA, support, partner teams, and fellow developers.

You use AI thoughtfully to improve how your team works,



creating repeatable practices that increase delivery speed while preserving code quality, test coverage, and system reliability.

You have a practical understanding of -or strong interest in -subscription products, recurring billing, payment integrations, stored payment methods, asynchronous callbacks, and the secure handling of payment data.
