About this role

Developers interact with our service, for the most part, using our client library software. We provide libraries on significant ecosystems (iOS, JVM, Web, and Infra & Automation). Our libraries are open-source and available on GitHub, and we are receptive to contributions from our customers, the developers they work with, and the broader open-source community.

As a Senior Software Engineer, you will play a key role in expanding and improving our open source client libraries, shaping how developers interact with our services. Your expertise and involvement will directly impact the success of our product and contribute to our team’s mission of expanding the Developer Ecosystems that we currently support.

  • Provide technical leadership. You’ll own one of our Developer Ecosystems, depending on your background:
    • iOS - Cocoa, flutter iOS, Swift
    • JVM - Java, flutter Android, Kafka, Kotlin
    • Infra & Automation - Rust, Go, Terraform
  • Design developer-friendly APIs and SDKs. You’ll formulate API proposals and the published specifications for new features, including liaison with the customers requesting them.
  • Collaborate on ambitious projects. You’ll work on a big project per period with other Developer Ecosystems Leads on any of the libraries that we own, or create a new one.
  • Manage complex development projects. You’ll be responsible for the entire lifecycle of development of our projects, including the development of new features, maintenance, bug fixing and testing.
  • Oversee external resources. You’ll lead and review work by freelancers and others that contribute to our ecosystems.
  • Engage and support the developer community. You’ll actively engage with the developer community to gather feedback and resolve issues raised against our client libraries.

We'd love to hear from you if you have

  • High expertise in one of our existing ecosystems (iOS, JVM, or Infra & Automation) mentioned above
  • Experience developing public-facing APIs and/or SDKs
  • Experience making technical decisions to drive projects forward efficiently
  • A strong focus on customer outcomes and the ability to quickly comprehend and convert business requirements into technical solutions
  • A growth mindset - you view intelligence, abilities, and talents as learnable and that they can be improved through effort
  • A pragmatic approach; the ability to quickly and successfully embrace change and adapt effectively in response
  • A passion for contributing to and optimizing software quality and ways of testing
  • Experience with multiple programming languages and willingness to work with any

It would be great, but not essential if you have

  • Experience building developer-first products.
  • Experience with products that are brought to market primarily through a product led growth approach.
