Our mission is to increase the GDP of the internet, and we have a staggering amount of work ahead. That means you have an unprecedented opportunity to put the global economy within everyone’s reach while doing the most important work of your career.

About the team

the company's Developer & End-user Experience Platform (DEEP) organization empowers all of the company's products with a shared product platform that helps with rapidly delivering high-quality, cross-product experiences across our UI and API surfaces. It focuses on providing a consistent and scalable developer experience that any developer (both internal and external) can leverage to accelerate a merchant's ability to create value using the company.

What you’ll do

We're looking for Backend Engineers who want to make an impact on managing money at a global scale with a passion for building ergonomic APIs. You'll play a key role in extending our balance management platform and in building out a new funds accessibility platform that enterprises and SMBs use. Our team collaborates with many cross-functional teams—from Infrastructure to Product—at the company to deliver innovative solutions that address evolving user needs.

  • Debug and solve critical production issues across services and multiple levels of the stack
  • Mentor engineers to help them grow
  • Collaborate with stakeholders across the company to build new features at large-scale, while improving internal engineering standards, tooling, and processes
  • Collaborate effectively in a distributed and hybrid team, maintaining open communication and strong connections with colleagues
Who you are

We're looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply. The preferred qualifications are a bonus, not a requirement.

Minimum requirements
  • 2–12+ years of industry software engineering experience (does not include internships or co-ops)
  • Strong coding skills in any programming language (we understand new languages can be learned on the job, so our interview process is language-agnostic)
  • Strong collaboration skills and the ability to work across workstreams within your team and contribute to your peers' success
  • Ability to thrive with a high level of autonomy and responsibility, with an entrepreneurial mindset
  • Interest in working as a generalist across varying technologies and stacks to solve problems and delight both internal and external users
Preferred qualifications
  • Experience with large-scale financial tracking systems
  • Good understanding and practical knowledge in cloud-based services (e.g., gRPC, GraphQL, Docker and Kubernetes, cloud services such as AWS, etc.)
