A day in the life and how you’ll make an impact:

  • As a Senior Full Stack Engineer for Product Engineering, your day will be spent creating and maintaining the products that let our customers manage their business payments in new ways.
  • We are building a platform that allows us to quickly iterate and launch custom solutions with high profile partners like Capital One and Shopify. We release features on an ongoing basis, build integrations, and develop tools that help us work more efficiently.
  • You'll interact with various parts of the system, from the back-end to the front-end, hence your work will involve dealing with diverse data structures and user interfaces. You'll work with technologies like AWS Lambda, Node.js, TypeScript, React, and MySQL to make this possible. We’re building REST APIs that we use internally and share externally, and new products based on these.
  • Cross-collaborate and discuss with other team members about current issues or future improvements, writing code to implement new features or fix bugs, conducting code reviews, and deploying updates.
  • Having a continuous improvement mindset, you'll strive to identify areas for improvement in the codebase and propose actionable solutions. 
  • This role will be vital to ensure we maintain the quality of our products, uptime and availability, and solving our users’ needs.

We work with modern technologies, including React, Node.js, TypeScript, and AWS microservices, and we are agile and collaborative, constantly looking for ways to improve our partner experience, product reliability, and codebase.

In this team, you’ll be part of a high-performance culture that values innovation, problem-solving, and teamwork.
