• We work together. In-office culture with people you want to work with. Lots of whiteboard space. Expense coffee, lunch, and dinner when in the office.

What You'll Do

• Participate in full life-cycle software development from inception to maintenance in production
• Work closely with other engineering teams and internal stakeholders to identify and drive improvements to the merchant experience
• Design and implement highly scalable and reliable systems
• Contribute ideas for new features and identify areas for improvement proactively
