About the Role

We are looking for a Back-End Engineer to help build the cloud services behind Rapsodo’s products. Every swing and pitch captured by a Rapsodo device becomes data that flows through our platform to athletes and coaches, often in real time. You will build and maintain the APIs, databases, and event-driven services that power that experience, using Go, PostgreSQL, and Google Cloud Platform (GCP). You will ship production code early, with mentorship and code reviews from senior engineers.

Responsibilities:

  • Lead the design, development, and maintenance of cloud-based backend applications using Go (Golang) programming language.
  • Collaborate closely with cross-functional teams to gather requirements, architect solutions, and implement features that align with business needs.
  • Utilize PostgreSQL and Elasticsearch to design and optimize databases and data storage solutions for efficient retrieval and real-time querying.
  • Develop real-time applications and services on Google Cloud Platform (GCP), leveraging cloud-native tools and technologies.
  • Implement RESTful APIs and microservices to ensure scalable and performant communication between various components of the application.
  • Write clean, maintainable, and testable code while following best practices for software development.
  • Monitor application performance and troubleshoot issues to ensure optimal functionality and user experience.
  • Stay updated with industry trends and emerging technologies, suggesting innovations that enhance our backend architecture.

Requirements

  • Bachelor's or higher degree in Computer Science, Software Engineering, or a related field.
  • Strong hands-on experience in backend development with Go.
  • Experience building cloud-based applications, preferably with GCP.
  • Solid understanding of PostgreSQL and database design.
  • Experience with RESTful APIs, event-driven systems, and microservices.
  • Familiarity with Docker, Kubernetes, and Git.
  • Experience with AI-assisted development tools and integrating AI into the software development lifecycle.
  • Strong problem-solving, communication, and collaboration skills.
  • Ability to work independently and effectively within a team.
