Senior Software Developer in Test
- San Francisco, CA
We believe the economy is better when everyone has access. When everyone has room to grow. No one should be left out because the cost is too great or the technology too complex. We started with a little white credit card reader but haven’t stopped there. We’re empowering the independent electrician to send invoices, setting up the favorite food truck with a delivery option, helping the ice cream shop pay its employees, and giving the burgeoning coffee chain capital for a second, third, and fourth location. We’re here to help sellers of all sizes start, run, and grow their business—and helping them grow their business is good business for everyone.
Our hardware team builds the tangible connection to all that is Square. As we introduce more and more of our products to the world, our hardware footprint expands.
As the Sr. Test Automation Engineer, you will be responsible for planning and executing integrated system testing with an emphasis on hardware-centric software risks for new and existing payment device projects. This includes cross-functional work with developers, QA Engineers, and product managers, to identify risk areas, testing responses and ensure total quality.
You should have an engineering background consisting of software development, low-level test automation systems design and development, and automating existing manual testing. You have a strong aptitude for learning new technologies with a good instinct for discovering defects in firmware, software, and hardware.
