At Spruce, we are reimagining trusted interactions by creating the world’s best software for packaging assertions digitally. We are a team of programmers developing world-class open source software implementing open standards for identity.

There are no well-worn paths or theoreticals here. Every Spruce technical staffer gets their hands dirty writing code, learning new technologies, and solving problems at the bleeding edge of our space. We hire results-oriented developers who love technology and are committed to intellectual honesty, user privacy, and innovation.

The ideal candidate for this test engineering role will have experience working on mobile applications through their full lifecycle, from concept through shipping to maintenance. You will work on a privacy-first digital identity wallet, controlled by the end user. We use a combination of core identity libraries, cutting-edge cryptography, and new interoperable identity standards.


  • Implement automated testing infrastructure in Rust and relevant cloud automation technologies such as Terraform, including test harnesses, mock APIs, and environments.
  • Write end-to-end tests that cover testing of libraries, applications and communications between devices and servers.
  • Work closely with the development team to help with good practices, and with the product team to assess the quality of critical components.
  • Help with debugging production issues.


  • Experience with automated testing in two or more of the following: backend systems, web applications, and mobile applications.
  • Proficiency with CI/CD platforms (e.g. GitHub Actions).
  • 4+ years of experience with automated testing.
  • Experience collaborating with geographically and culturally diverse engineering scrum teams.


  • Professional software development experience in a modern backend programming language.
  • Experience with Rust.
  • Experience with digital identity standards (e.g. OAuth2.0, JOSE, X.509)
  • Experience with cryptographic primitives (e.g. secure enclaves, hardware-based cryptography).
  • Experience with cloud environments and technologies (e.g. AWS, Terraform, Kubernetes).
  • Bachelor's Degree in computer science, IT, engineering, or related field.

We are passionate about cultivating a thriving culture of diverse individuals who bring unique perspectives to our mission. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or Veteran status.
