Senior Quality Engineer

Apply for this Role →

Do you want to help scientists make breakthroughs, doctors save lives, and historians learn from our past? Join our small, fully-remote software development team that builds tools to connect scholars of all disciplines with the peer-reviewed journal articles that advance their research.

Third Iron's industry-leading software services BrowZine and LibKey are used by millions of students, doctors, industry researchers, and scientists affiliated with over 2,000 libraries at universities, hospitals, corporations, and government departments in over 35 countries, including places like Stanford University, Mayo Clinic, NHS England, and University of Hong Kong.

In a refreshing change from advertising-dependent tech companies or those who sell user data, we instead have a straightforward business-to-business model. We sell our subscription-based services to libraries that may be used by anyone affiliated with them. We do not sell user data. Our focus is on building the best software to enable research that changes the world.

Your Role

As a Senior Quality Engineer, you will help lead our Quality Assurance approach, defining and improving our quality processes across all of our systems. You will also lead the tooling and implementation of automated UI testing, as well as incorporating manual exploratory testing where appropriate.

Products we are responsible for include web apps, a browser extension, internal web app tools, Javascript code that enhances other library tools, and some APIs used by external library technology groups.

Quality-focused teammates are fully integrated into the Software Development team. You attend our quick daily standup, our end-of-sprint demo day, retrospective, and requirements discussion meetings.

Each of our systems already have an extensive suite of automated tests that are run on every commit in CI. However, we are looking to improve our test suites with more UI automation, helping us capture precise reports of how our systems are performing to enable even stronger confidence that things are behaving as we intend, without undesired visual glitches or behavior regressions.
