Full Stack Developer (Senior Level) - Subscription Engine Focus

We're a nimble and agile startup revolutionizing the mobility landscape with our innovative subscription‑based mobile app. We're seeking a skilled and experienced Senior Full Stack Developer to spearhead the rebuilding of our core subscription engine. In this critical role, you'll be instrumental in designing, developing, and deploying a new, custom‑built subscription platform in Kotlin, hosted on Google Cloud, that will power our B2B / B2C solutions. You'll collaborate closely with our Head of System Architecture to bring this vision to life.

Tasks

• Subscription Engine Re‑Architecture: development of our next‑generation subscription engine, transitioning away from WooCommerce to a custom solution built in Kotlin and React
• Backend Development (Kotlin / GCP): Develop robust, scalable, and secure backend services in Kotlin, leveraging the full potential of Google Cloud Platform for hosting and related services.
• API Development & Integration: Design and implement clear and efficient APIs to connect the new subscription engine seamlessly with our front‑end mobile application. (Note: While API connection is crucial, the primary focus of this role is on the backend engine itself, not extensive front‑end development.)
• B2B Solution Focus: Develop and optimize the subscription engine specifically to support our B2B offerings, including the Jobticket+ and the B2B Dashboard.
• Data Modeling & Management: Design and implement the necessary data models and database schemas to efficiently manage subscription data.
• Payment Gateway Integration: Integrate with various payment gateways to ensure seamless and secure payment processing within the new subscription engine.
• Testing & Quality Assurance: Implement comprehensive unit, integration, and end‑to‑end tests to ensure the reliability and stability of the new subscription engine.
• DevOps & Deployment: Work with our team to establish and maintain CI / CD pipelines for the efficient deployment and management of the subscription engine on Google Cloud.
• Collaboration with System Architect: Work closely with our Head of System Architecture on the overall design, architecture, and implementation of the new subscription engine.
