Today, we’re a partner to sellers of all sizes – large, enterprise-scale businesses with complex commerce operations, sellers just starting out, as well as merchants who began selling with Square and have grown larger over time. As our sellers scale, so do our solutions. We all grow together.
There is a massive opportunity in front of us. We’re building a business that is big, meaningful, and lasting. And we are helping sellers around the world do the same.
Our hardware team builds the tangible connection to all that is Block. As we introduce more and more of our products to the world, our hardware footprint expands. In this role, you will be responsible for developing software that simulates Block's hardware products, in order to expand our automated testing capacity and make the lives of our firmware developers easier by giving them the ability to test firmware code without using hardware devices. Ideally you will have firmware development experience, but have interest and/or experience developing host-side systems that run on the cloud.
- Build scalable simulators for all of Block's hardware products
- Understand our payments processor at the lowest level, helping to build a virtualized version
- Understand code written within the constraints of tiny embedded systems and modify it as necessary to work on Linux and Mac
- Write integration code with CI/CD systems and cloud infrastructure services
- Write and collaborate on new system-side code; including protocol design
- Develop tests to validate product features, drivers, and system functionality
- Collaborate with firmware, iOS and Android developers that will be using the simulators you build
- 5+ years of relevant industry experience
- A software development discipline, including modularization, documentation, and test methods
- Firmware / Embedded software development experience
- Expertise in C software development, tools, and debugging
- Experience integrating with CI/CD and cloud infrastructure services (e.g. AWS, GCP)
- Understanding of common communications protocols (e.g. SPI, UART, I2C, USB)
- BS in CS, CE, EE, or equivalent practical experience
- Experience with real-time operating systems
- Experience debugging issues cross-functionally
Even better if you have experience in any of the following:
- Experience with wireless protocols (e.g. BLE, NFC)
- Experience using Python (or similar scripting languages) in automated testing, build systems, or device firmware communication
