DFINITY is reimagining the Internet as a public network that hosts secure software and services. The Internet Computer is a new technology stack that is fast and scales to billions of users around the world, and supports a new kind of autonomous software that promises to reverse Big Tech’s monopolization of the internet. DFINITY was founded in 2016 by Dominic Williams and is backed by top-tier institutions including Polychain Capital and Andreessen Horowitz.

Are you ready to identify weaknesses in our stack, to discover bugs in our APIs and to improve the quality of a complex product by establishing a strong test harness? Are you passionate about building test automation to ensure that regressions are discovered before they reach production? Do you have hands-on experience with distributed systems and like to work with them on a daily basis? Then we have a role for you!

You will collaborate with a motivated team that works on some of the most sophisticated, secure, and efficient distributed messaging protocols ever to be deployed. We are a vibrant startup that has grown to 180+ employees with offices in the Bay Area and Zurich.


  • Extend our existing system and production test frameworks written in Rust, Python and bash.
  • Integrate automated tests into our GitLab pipelines and drive improvements based on data collected in the Elastic stack.
  • Identify design and implementation weaknesses of the Internet Computer using state-of-the art testing strategies:
    • Functional tests
    • Performance tests
    • Fuzz testing
    • Chaos and network testing    
  • Collaborate with engineering teams to reproduce and pinpoint uncovered defects and anomalies.
  • Establish best practices that capture the learnings from testing. 
  • Support the definition of quality gates for software releases based automated tests.
  • Participate in R&D design reviews to incorporate learnings from your verification work early on in the design process.


  • You’re a skilled programmer with a deep understanding of at least one systems software language like C, C++, or Rust.  Our distributed systems components and part of our test framework is written in Rust (and we’re committed to helping you learn if you lack experience with Rust).
  • You have excellent communication skills and can explain complex topics with clarity and conciseness.
  • You have experience releasing live services to a large user base
  • You’re experienced in automating test scenarios and their integration in a DevOps pipeline - preference for experience with GitLab and the Elastic stack. 
  • You’re eager to understand a software stack in detail and to rigorously test it to ensure that it behaves as expected.
  • A quality mindset that demands excellence from yourself and your team.
  • You enjoy collaborating with other technical experts, across teams and to jointly drive for software and process improvements.
  • Experience working with deployment tooling such as Terraform and Ansible is a plus.
