Backend Engineer • Senior

Who you are

You have 5+ years of backend engineering experience building scalable and robust systems — you've designed and implemented complex backend architectures that support high transaction volumes and ensure data integrity. Your expertise in Scala allows you to write clean, efficient code that meets the demands of a fast-paced environment.

You are familiar with Google Cloud Platform (GCP) services, including GKE, Pub/Sub, and BigQuery — you understand how to leverage these tools to build and maintain cloud-native applications. Your experience with containerized microservices architecture enables you to contribute effectively to a system with over 200+ services running in Kubernetes.

You have a strong data-driven mindset, utilizing tools like Amplitude and Datadog to monitor system performance and user engagement — you thrive on making informed decisions based on analytics and metrics. Your collaborative spirit allows you to work closely with product managers and cross-functional teams to align on project goals and deliver high-quality features.

You are comfortable operating autonomously while maintaining strong communication with your team — you value asynchronous decision-making and understand the importance of alignment in a remote work environment. You are eager to iterate on features and ship code quickly, contributing to the overall success of the product.

Desirable

Experience with fraud detection systems or payment processing is a plus — you understand the challenges and requirements of building secure and reliable financial applications. Familiarity with agile methodologies will help you adapt to the team's workflow and contribute to continuous improvement.
