Software Engineer, Tools & Services

Full-time

Company Description

Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

Job Description

Our inclusive 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. You will develop the software tools used to develop and test Square's hardware products.

Our team looks across the software development lifecycle to find opportunities to help speed up delivery and improve quality. We build: custom circuit boards running C, C++-based virtual test environments for firmware, Python command line tools that support firmware testing and CI/CD pipelines, and even web-based applications used by developers to manage test-related data. While team members focus on a specific area and tool chain, there are opportunities to try something else if you are interested. You will report to our Senior Software Engineering Manager for the Off-Device Test Environments team.

Role Location:

We want employees to be able to reside where they feel most creative and productive. You will be part of an org and team that works across Pacific, Central and Eastern Time Zones.

In this role, you and your direct team will be based in the Eastern time zone. This role is open to all people who can be effective partners with this team, including sharing and adjusting to typical working hours.

Qualifications

You have:

BS in CS, CE, EE, or equivalent practical experience
2+ years of software development experience
Expertise in C and C++ software development, tools and debugging
Experience in Python
System software/platform development experience
Experience leading development of core features within large systems
A History of mentoring engineering team members to raise technical standards
Experience collaborating across multiple teams, disciplines and locations keeping the best interests of customers in mind
Have a broad range of knowledge and be willing to work across our technology stack

Even better if you have experience in any of the following:

Firmware/embedded software development experience
Understanding of common communications protocols (e.g. SPI, UART, I2C, USB), debugging practices (e.g. JTAG and associated GDB integrations)
Experience working with CMake or similar build systems
Experience with Android Framework & application level development
Understanding of the Android framework internals and AOSP code
