Jobbeschreibung

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.

• 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.)

• Data Modeling & Management: Design and implement the necessary data models and database schemas to efficiently manage subscription data.

• 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.

Requirements

• Exceptions are the following European countries: Albania, Bosnia and Herzegovina, Georgia, Montenegro, North Macedonia, Serbia, Turkey, Ukraine

Experience and Skills

• Significant experience as a Full Stack or primarily Backend Developer with a strong understanding of system architecture.
• Proven expertise in developing backend systems with Kotlin and React.
• Must have: Experience building APIs using a domain‑driven design approach.

• Experience with testing frameworks and methodologies.

Personal Attributes

• Excellent communication and collaboration skills, particularly in working with technical leadership.
• Ability to work independently and manage tasks effectively in a remote environment.

Benefits

• Ownership: The opportunity to lead the development of a critical component of our platform and have a significant impact on our B2B strategy.
